Read This Page!
1. Turn the channel level, mon 1, and FX/mon 2
controls fully down.
We realize that you must be really keen
to try out your new powered mixer, but
please read the safety instructions on
page 2, and this page first.
2. Turn down the compressor controls (ch. 1–4).
3. Set all the EQ controls to the center, including
the graphic EQ sliders.
4. Turn down the main level and monitor 1 level
controls, and turn on the powered mixer.
Setup
The PPM608 powered mixer is designed for ease of
operation, and to be set up quickly and easily.
5. For each channel, press the gain switch in (low
gain) if you are using a line-level source. Press
it out (high gain) if you are using a microphone
or other low-level source.
Place the powered mixer in a position where it is easy
to reach the controls. All the controls and input con-
nection points are located on the front panel so you can
make quick adjustments and connections on stage.
6. For condenser mics, push in the phantom
power switch. If you are using both condenser
and dynamic mics, don’t worry. Phantom power
will not hurt most dynamic mics. Check the
microphone’s user manual if you’re not sure.
Make sure there is at least 6 inches of airspace behind
the powered mixer for ventilation. There are two fans
inside the cabinet to cool the power amplifier section.
Use the powered mixers in a nice clean and dry environ-
ment, free from dryer lint and dust bunnies.
7. Play something into an input at real-world lev-
els, and turn up the channel level to U (unity).
8. In normal playing, the channel's OL LED should
only light occasionally. If it stays on for a large
portion of your performance, check that the
gain switch is set correctly.
Connections
1. Be sure the rear-panel power switch is off
before making any connections.
9. Slowly turn up the main level control until you
hear the signal in your speakers.
2. Push the linecord securely into the IEC connec-
tor on the rear panel, and plug the other end
into a 3-prong AC outlet that is properly config-
ured for the voltage of your powered mixer.
10. Repeat steps 5 to 8 for the remaining channels.
11. If needed, apply some EQ wisely.
12. Adjust the levels to get the best mix. Keep the
level controls fully down on unused channels.
3. Plug a balanced microphone into one of the mic
XLR (3-pin) connectors on the front panel. Or
you can connect any line-level signal (key-
board, or guitar preamp) to a line input jack
using a TS or a TRS 1/4" plug.
Other Notes
•
Only connect the powered mixer's speaker-level
outputs to passive loudspeakers.
4. You can connect a guitar directly to inputs 5 or
6 without need for a DI box, if you press the hi-z
switch on these channels.
•
When shutting down, turn off any external
amplifiers or powered loudspeakers first. When
powering up, turn on any external amplifiers or
powered loudspeakers last.
5. The insert jacks are used if you want to connect
an external effects or dynamics processor into
the signal chain. See page 13 for more details.
•
Save the shipping box!
6. Plug the speakers (4 ohms or greater) into the
speaker output jacks on the rear panel. If you
plug two speakers into a side, each speaker
must be 8 ohms or greater to maintain a 4-ohm
minimum load on the amplifier. Use at least
18 gauge speaker cable with 1/4" TS plugs or
Speakon® plugs. For now, set the rear panel
power amp mode switch to stereo mains.

1. POWER CONNECTION
3. SPEAKER-LEVEL OUTPUTS
This jack accepts the supplied 3-prong IEC AC power
cord.
These output connections provide speaker-level
output power from the internal power amplifiers to your
passive speakers. The power output of the PPM608 is
300 watts rms per channel into 4 ohms.
Before you plug the AC power cord into the
powered mixer, make sure that the voltage of
your unit is the same voltage as your local AC
mains supply. Use only the power cord supplied. Also,
disconnecting the plug’s ground pin is dangerous. Please
don’t do it.
Only passive loudspeakers should be con-
nected to these speaker-level outputs.
The outputs can be selected with the amp mode
switch [4] to be either the stereo main mix, mono main
mix/monitor 1, or monitor 1/monitor 2.
2. POWER SWITCH
Two common types of connector are provided for your
convenience: Speakons and 1/4" TS.
Press the top of this rocker switch inwards to turn on
the mixer. The front panel power LED [31] will glow
with happiness, or at least it will if you have the mixer
plugged into a suitable live AC mains supply.
•
Speakon outputs are wired Pin 1+ positive
(hot) and Pin 1– negative (cold).
Press the bottom of this switch to turn off the mixer,
whenever you feel that this would be a safe thing to do.

As a general guide, you should turn on your
mixer first, before any external power ampli-
fiers or powered speakers, and turn it off last.
This will reduce the possibilities of any turn-

5. VENTILATION and REAR PANEL
Ventilation holes in the rear panel and the bottom
panel allow the internal fans to flow breezy and minty-
fresh cooling air over the internal power amplifiers. Do
not obstruct these holes, or the amplifiers may overheat
and shut down.

Do not remove the feet, as these keep the
powered mixer off the ground for ventilation.
Do not place the powered mixer on a carpeted
or similar soft and fuzzy surface that may obstruct the
ventilation holes in the bottom panel.
1/4" TS Connection
These two types of outputs are wired in parallel, and
it is possible to use both types at once.
The minimum impedance that the powered
mixers can handle is 4 ohms per channel, and
we recommend that you do not go below this.
If you are using both outputs per channel, make sure
each loudspeaker is 8 ohms impedance or greater.
6. HANDLES
These metal handles are delightfully modern in
styling and good looks, and truly represent the perfect
accessory to accent your busy work schedule. Use the
handles to carefully lift and move the powered mixer.
Better yet, have someone else lift it for you. They will
be remarkably pleased with its light weight, and high
power, ideal for all sorts of road trips.
4. POWER AMP MODE SWITCH
This three-position switch lets
you choose which signal paths
from the mixer section are sent
to the internal power amplifiers.
This allows considerable flexibil-
ity in the use of the powered mixer. For example, if you
already have powered loudspeakers, you could use the
PPM608 power amplifiers to run passive stage monitors.
Stereo Mains
The output from channel A is the left side of the main
mix, and the output from channel B is the right side of
the main mix. Choose this position to play a straight
stereo show.
Mains/Monitor 1
Channel A is the mono main mix, and channel B is the
monitor 1 mix. In this setup, you could run a mono PA
system on one channel, and a passive stage monitor
system on the other.
Monitor 1/Monitor 2
Channel A is the monitor 1 mix, and channel B is the
monitor 2 mix. In this setup, the internal power am-
plifiers are powering two independent passive stage
monitor systems.
Make sure that the front panel FX send/mon
2 send switch [47] is pressed in (mon 2), or
there will be no monitor 2 signal to the inter-
nal power amplifier channel B.
If anything is plugged into the front panel
power amp inputs [20], then this switch has
no effect. The internal power amplifier will
play whatever signals are coming into the
power amp inputs.

7. MIC INPUTS
This is where you plug in things such as: microphones,
We use phantom-powered, balanced microphone
inputs just like the big studio mega-consoles, for exactly
the same reason: This kind of circuit is excellent at
rejecting hum and noise. You can plug in almost any
kind of mic that has a standard XLR-type male mic con-
nector.
line-level instruments, guitars, and effects, a recorder,
PA system, powered monitors, powered subwoofer etc.
(The speaker-level outputs from the internal power
amplifiers are on the rear panel.) Check out the hookup
diagrams for some connection ideas. See Appendix B
(page 25) for further details and some rather lovely
drawings of the connectors you can use with your mixer.
Professional ribbon, dynamic, and condenser mics all
sound excellent through these inputs. The mic inputs
will handle any kind of mic level you can toss at them,
without overloading.
Microphone-level signals are passed through the
mixer's splendid microphone preamplifiers to become
line-level signals. Because more gain is required to
boost the microphone level signals, make sure the gain
switch [28] is in the up position when you are using
microphones.
Channels 1 to 4 have the extra benefit of built-in sig-
nal in-line compressors [29]. These can be adjusted to
add just the right amount of compression to your vocals
and help prevent distortion and the effects of tonsillitis.

PHANTOM POWER
12. INSERT (CH. 1 to 6)
Most modern professional condenser mics are
equipped for phantom power, which lets the mixer
send low-current DC voltage to the mic’s electronics
through the same wires that carry audio. (Semi-pro
condenser mics often have batteries to accomplish the
same thing.) “Phantom” owes its name to an ability to
be “unseen” by dynamic mics (Shure SM57/SM58, for
instance), which don’t need external power and aren’t
affected by it anyway.
These unbalanced 1/4" jacks on channels 1 to 6 are for
connecting serial effects processors such as compres-
sors, equalizers, de-essers, or filters. The insert point
is after the gain switch [28] and compressor circuits
(on channels 1 – 4), but before the channel’s EQ and
level [27] controls. The channel signal can go out of
the insert jack to an external device, be processed (or
whatever) and come back in on the same insert jack.
To do this requires a special insert cable that must be
wired thusly:
The mixer's phantom power is globally controlled
by the phantom [42] switch on the front panel. (The
phantom power for all channels is turned on and off
together.)

Never plug single-ended (unbalanced) micro-

jacks if phantom power is on.
Tip = send (output to effects device)
Ring = return (input from effects device)
Sleeve = common ground
Do not plug instrument outputs into the mic
XLR input jacks with phantom power on,
unless you know for certain it is safe to do so.
Insert jacks can be used as channel direct outputs;
post-gain, and pre-EQ. See the connector section on
page 26 (figure G) showing three ways to use insert con-
nections.
8. MONO LINE INPUTS (CH. 1 to 4)
These 1/4" jacks share circuitry (but not phantom
power) with the mic preamps, and can be driven by bal-
anced or unbalanced sources.
13. TAPE OUTPUTS
To connect balanced lines to these inputs, use a 1⁄4"
Tip-Ring-Sleeve (TRS) plug.
These stereo unbalanced RCA outputs allow you
to record the main stereo mix onto a tape deck, hard
disk recorder, automatic CD burner, or a computer, for
example. This allows you to make a recording for poster-
ity/archive/legal purposes whenever the band gets back
together again.
To connect unbalanced lines to these inputs, use a
1⁄4" mono (TS) phone plug or instrument cable.
9. LINE/INSTRUMENT INPUTS (CH. 5 and 6)
The tape output is the stereo main mix, not affected
by the main level [34], or the main graphic EQ [32].
The line-level inputs for channels 5 and 6 can also
accept instrument-level signals if the hi-z switches
[30] are pressed in. This allows you to connect guitars
directly to channels 5 and 6, without the need for a DI
box. The input impedance is optimized for direct con-
nection, and high-frequency fidelity is assured.
14. BREAK SWITCH and LED
This important "take-a-break" switch quickly mutes
all the microphones and the mono channel line-level
inputs when the band is between sets. This will prevent
protestors or rogue karaoke singers from storming the
stage at the interval. The monitor 1 and FX/monitor 2
outputs, and the drive signal to the internal effects are
also muted. The LED will come on, as a reminder that
the break switch is engaged. Check this LED first, if you
are having trouble with no sound in your system.
10. STEREO LINE INPUTS (CH. 7 and 8)
Channel 7 and 8 have stereo line inputs. If you
just have a mono source, plug it into the left input of
channel 7 or 8 (labeled left/mono), and the signal will
appear (as if by magic) equally on the left and right of
the main mix.
You can still play the stereo channel line inputs
[10] and RCA inputs [11] in the main stereo mix. For
example, you could play a soothing CD to restore order
before the police arrive.
11. RCA INPUTS (CH. 7 and 8)
Channel 7 and 8 also have RCA line inputs, suitable
for connecting the line-level, unbalanced output from
CD players, tape decks, iPod docks etc. They are not
suitable for direct connection of phono-level outputs
from turntables, as a phono preamp is required.

If they want "more me, and less Keith," you can turn
up their channel's FX/mon 2 control, and turn down
Keith's. (If you were using monitor 1 to feed the stage
monitor, then you would adjust the mon 1 control [21]
on each channel.)
15. FX/MON 2 SEND OUTPUT
This 1/4" TRS line-level output can be used to feed an
external effects processor (FX) or a second set of stage
monitors (mon 2). The output from here is a copy of
what goes into the internal FX processor, being the care-
ful mix of all channels whose FX/mon 2 control [22] is
turned more than minimum.
The processed output of the internal FX does
not come out of here, but is added internally
to the main mix or monitor 1 mix.
To channel 5 or 6
instrument inputs
The overall output level can be adjusted with the
FX/mon 2 send control [45], and it can be either post
or pre channel level, depending on the setting of the FX
send/mon 2 send switch [47] as follows:
From mon 1 or mon 2
line-level output
SRM450v2
MONITOR 2 or FX?
Powered Stage Monitor
To run one set of stage monitors, use the monitor 1
system because it has its own graphic EQ [37], master
level [39], and meter [41]. To run another set of moni-
tors, set the FX send/mon 2 send switch to mon 2.
To feed an external effects processor, such as a nice
sound effect, or delay, the feed should be "post-fader."
In this way, any changes to the channel level will also
affect the level going to the external processor. The
processed output from the effects processor is usu-
ally returned to a spare channel, and you can carefully
mix the original unprocessed channel (dry) and the
processed channel (wet). Altering the original channel
level increases both the wet and dry signals and keeps
them at the same delicate ratio. (For example, the re-
verb remains at the same level relative to the original).
Stage monitors allow the talented musicians in your
band to hear themselves clearly on stage, and this can
often be a good thing. The monitor output can be care-
fully adjusted in level using the channel FX/mon 2 con-
trols [22], and not change if the channel levels or main
mix levels are adjusted. This is known as "pre-fader."

(The main mix still plays the full frequency range,
this sub output is just a mono copy of the range below
100 Hz for external subwoofers.)
EFFECTS: SERIAL OR PARALLEL?
“Serial” means that the entire channel signal
leaves the mixer (insert [12] send), is routed
through the effects device, and returns to the
mixer (insert return). Examples: compressor,
limiter, graphic equalizer. Line-level sources can also be
patched through a serial effects device before connec-
tion to the mixer.
19. MAIN OUTPUTS
These 1/4" balanced TRS outputs supply the stereo
main mix at line-level. You can connect these outputs to
the line-level inputs of external power amplifiers run-
ning passive loudspeakers, or to the inputs of powered
loudspeakers (or not use them at all, if you don't have
the external gear).
“Parallel” means that a portion of the signal in the
mixer is tapped off to the device, processed, and re-
turned to a spare channel of the mixer to be mixed with
the original “dry” signal. This way, multiple channels
can all make use of the same effects device. Examples:
reverb, digital delay. The internal effects are parallel,
as all channels can make use of it, and the processed
output is added to the main mix.
These outputs play the same signal as the rear-panel
speaker-level outputs [3] (when set to stereo mains),
only at line-level.
These outputs can also be used to feed an external
stereo effects processor or other device, and have the
processed output of that device feed the power amp
inputs [20]. This places the device in-line and it will
affect the main mix.
16. FX FOOTSWITCH
This 1/4" TRS connector is where you can connect a
footswitch. This will allow you to easily mute or un-mute
the internal effects, while stamping your foot and look-
ing like you were mad about something. Any one-button
on/off footswitch will work.
Another super idea is to use an external
active crossover. This splits the line-level main
output into two or three frequency bands.
The high-frequency line-level output of the
If the internal effects have already been muted with
the front panel mute switch [50] then the footswitch
has no effect, but you can still stamp your foot and pout
if that helps any. Cultivate that bad-boy image.
crossover could be connected to the power amp inputs
[20], so the internal amplifiers will power your top-fre-
quency-range loudspeakers. The active crossover's low-
frequency outputs could connect directly to powered
subwoofers. In this way, you can take some of the strain
off your powered mixer's internal amplifiers, and have
the powered subwoofers crank out the bass.
17. MON 1 SEND
This 1/4" TRS connector allows you to send the moni-
tor 1 line-level output to stage monitors. These could
either be passive stage monitors powered by an external
amplifier, or powered stage monitors with their own
amplifier built in.
20. POWER AMP INPUTS
These 1/4" TS unbalanced inputs allow you to connect
line-level signals directly to the input of the internal
power amplifiers.
The monitor signal is the sum (mix) of all the chan-
nels whose mon 1 control [21] is set to more than
minimum. The overall output level can be adjusted with
the mon 1 master level [39] and its EQ tweaked with
the monitor graphic EQ [37].
The amplifiers will only play what you put in, and only
the precision passive EQ switch [43] and limiters [44]
will affect the output. The power amp mode switch [4]
has no effect, and the meters will not show the levels.
Plugging anything in here, does not affect any of the
line-level outputs.
The monitor 1 output is not affected by the main
master level [34], or the channel level controls [27].
This allows you to set up the monitor mix and level just
right, and not have it change every time a channel level
or the main mix level is adjusted. This is the main aim
of a monitor mix: independence from the main mix.
You could patch a device between the main outputs
[19] and these inputs, in which case, the controls and
meters will work except for the power amp mode switch.
These inputs are also useful when you need more
channels then the PPM608 provides. You could connect
the line-level outputs from another mixer, and use it to
control the mix and levels playing in loudspeakers at-
tached to the powered mixer.
18. MAIN SUB
This 1/4" TRS connector supplies a copy of the mono
main mix below 100 Hz. This is usually patched to the
inputs of an external power amplifier running a passive
subwoofer, or directly to a powered subwoofer. Whatever
adjustments you make to the main mix, will affect this
output below 100 Hz.
The external mixer or device will control the
volume, so turn it down at first, or the pow-
ered mixer may come on at full volume.

“U” like Unity gain
Channel Controls
Mackie mixers have a “U” symbol on almost every level
control. It stands for “unity gain,” meaning no change in
signal level. The labels on the controls are measured in
decibels (dB), so you’ll know what you’re doing level-
wise if you choose to change a control setting.
The eight vertical channel strips look very similar,
with only a few differences between them. Each chan-
nel works independently, and just controls the signals
plugged into the inputs directly below it.
Mono Channels 1 to 6
Signal Flow
•
Channels 1 to 6 are mono channels, and their
controls affect either the mono mic input or the
mono line-level input.
The block diagram on page 29 shows the signal flow,
but here is a short description of the flow through the
channel strip section:
•
•
•
•
Channels 1 to 4 have a built-in signal in-line-
compressor circuit with adjustable threshold.
The mic inputs and mono line inputs each feed a
preamplifier whose gain is set by the gain switch [28].
The stereo channel line inputs and RCA inputs do not go
through a gain-selectable preamp.
Channels 5 and 6 have a hi-z switch [30] so you
can connect guitars directly.
The 3-band EQ has shelving high, shelving low,
and peaking mid EQ.
The signal then passes through the compressor circuit
(ch. 1 to 4 only), then through the channel EQ, and the
channel level [27].
The mono signals are split equally to the left
and right of the main mix.
The mon 1 control [21] taps the signal off just before
(pre) the channel level.
Stereo Channels 7 to 8
•
Channels 7 and 8 are stereo channels, and their
The FX/mon 2 control [22] taps the signal off before
(pre) and after (post) the channel level. The FX send/
mon 2 send switch [47] lets you choose which is used.
Post is used for FX, and pre is for monitor 2.
controls affect either the mono mic input, ste-
reo line-level input, or stereo RCA inputs. (The
mono mic input of each stereo channel is split
equally to left and right).

The stereo channel EQ is a 3-band design just
like the mono channel EQ.

CHANNEL EQUALIZATION (EQ)
This control allows you set up a nice monitor mix,
independent of the main mix or the monitor 2 mix.

you never heard. Peaking means that certain frequen-
cies form a “hill” around the center frequency.
With too much EQ, you can really upset
things. We’ve designed a lot of boost and cut
into each equalizer circuit because we know
that everyone will occasionally need that. But
if you max the EQ on every channel, you’ll get mix mush.
One of the powered mixer's internal amplifiers can
power passive stage monitors if you set the power amp

repeatedly using full boost or cut, consider altering the
sound source, such as placing a mic differently, trying a
different kind of mic, changing the strings, or gargling.
22. FX/MON 2
These controls allow you to send a sample of each
channel's signal to the internal FX processor, and to the
FX/mon 2 line-level output [15] to run external proces-
sors, or a second set of stage monitors.

27. CHANNEL LEVEL
This adjusts the level of each channel onto the main
mix. The “U” mark indicates unity gain, meaning no
increase or decrease of signal level. All the way up
provides an additional 20 dB, should you need to boost
a section of the band. If you find that the overall level
is too quiet or too loud with the level near unity, you’ll
want to confirm the gain switch is set correctly.
IN (LOW)
Gain = 25 dB
Gain = 0 dB
Gain = 20 dB
OUT (HIGH) Gain = 45 dB
This is the first control that the input signals meet. It
allows you to choose the level depending on the type of
input source you have connected. If it is set incorrectly,
then the input signals may overload the mixer, caus-
ing distortion, or it may come in too low, and be lost in
noise.
The gain switch allows you to make the initial level
adjustment, appropriate for the connected device (mic
or instrument, for example). The channel level controls
[27] are more for fine-tuning, to balance the channels
appropriately for the song.

29. COMPRESSOR

Channels 1 to 4 have an in-line compressor circuit
with a variable threshold. This is very useful for com-
pression of vocals, for example.
+15
+10
+5
When the incoming signals exceed the threshold level
set by this knob, the signal level is automatically com-
pressed. This reduces the dynamic range, and reduces
the chance of distortion due to overloading the input
signals.
+0
-5
Dynamic range is the difference in level be-
tween the quietest part of your song and the
loudest part. Using a compressor, you are able
to squeeze the dynamic range, resulting in
an overall steadier, more constant volume level for the
signal. It helps sources such as vocals "sit" properly in
the mix, and it is very useful for live sound as well.

INPUT SIGNAL STRENGTH dBu
The compression ratio is fixed at around 6:1, with
a soft knee response. The threshold can be adjusted
clockwise from off (no compression) to 0 dBu (max).
The other blue curves represent in-between positions
of the compressor knob, with higher thresholds before
compression begins.
As an example, suppose the threshold is set to maxi-
mum. An incoming signal reaches the threshold of 0
dBu. As it increases beyond the threshold, it becomes
compressed at a ratio of 6:1. This means that even if the
input further increases by 6 dB, the actual output only
increases by 1 dB. This compresses the output signal, so
there is more protection to your system from distortion
and overload due to poor microphone technique (say
it ain't so) and general pops, bangs and heavy metal
screaming. The soft knee means that the compression
slowly ramps up to 6:1 from the threshold. It does not
jump abruptly to 6:1, as this would be hard knee com-
pression, and hard on the ears too.
Separate compressors often have controls such as
compression ratio, threshold, soft knee/hard knee, at-
tack time, and release time. These last two affect how
quickly the compressor kicks in when the input exceeds
the threshold, and how quickly it is released after it
drops below the threshold. In this powered mixer com-
pressor, these parameters are specially chosen to give
you the best overall performance.
Adjust the threshold carefully, so your dynamic range
is still lovely, without distortion or overload during the
performance. Run through a few practice songs and
adjust the compression as required.
The following graph shows the input signal
level going into the compressor, versus the
output level coming out of it. It is the typical
graph to see when compressors are discussed,
and is just the kind of thing our engineers like to talk
about during the company Christmas party.
30. HI-Z SWITCH
Channels 5 and 6 are the only place to plug
in guitars and basses directly to the powered
mixer. These switches must be pressed in first.
If you connect a line-level device, such as a keyboard
or drum machine, make sure these switches are out.
(They only affect the 1/4" line inputs of channels 5 or 6,
not the XLR mic inputs.)
If the compressor is off, then the input = output. For
example an input signal level of +5 dBu results in an
output level of +5 dBu. The diagonal line from lower left
to upper right represents x = y, that is, input = output.
To use guitars or other instruments on other chan-
nels, you will need to use an external DI box first. With-
out the DI box, (or if these switches are not pressed in)
guitars will sound dull and muddy.
At the maximum compression, the threshold is set
at 0 dBu, and the input to output relationship is repre-
sented by the lower blue curve. If the input is –5 dBu
(that is, below this threshold), the output is –5. As the
input reaches 0 dBu, the output is a bit less than 0 dBu.
If the input is +5 dBu, the output is about +2 dBu. If
the input reaches +10 dBu, then the output is +3 dBu.
Notice the shapely curve of the soft knee between the
diagonal slope of x = y and the compressor slope of 6:1
(the compression ratio).

Master Controls
As with the channel EQ, just take it easy.
There is a large amount of adjustment, and
if you are not careful, you can upset the
delicate balance of nature. Although it may
not seem cool to actually turn down controls,
with EQ it is often your best option. Turn
down the offending frequency range, rather
than boost the wanted range. You can reduce
the level of some frequency bands where
feedback occurs.

With this constant–Q graphic
EQ, the bandwidth (and Q) of a
frequency band doesn't vary with
41
the amount of boost or cut, and it
has minimal effect on adjacent bands for all
settings of the slider levels. (There's always
some effect on adjacent bands to avoid too
much variation or ripple between bands,
but the constant-Q design keeps this fairly
constant for all settings.) The position of the
sliders gives a good indication of the fre-
quency response across the audio band. Non-
constant types of EQ (on other mixers) give
a wider bandwidth for lower levels of boost
or cut, and narrows as the level goes up or
down. For example, if you're boosting 500 Hz

and 2 kHz slightly, the 1 kHz band will also be boosted,
even though the 1 kHz slider is in the flat position.
This LED comes on when the powered mixer is
plugged into the correct-voltage AC mains supply, and
the rear panel power switch [2] is on.
33. FX TO MAIN
This knob lets you adjust the level of the internal ef-
fects being added to the main mix. It is a stereo control,
as the output from the internal effects processor is
stereo and is added to the left and right main mix.
If the LED does not turn on, make sure the AC
power is live, both ends of the power cord are correctly
inserted, your electricity bill has been paid, the lights in
town are on.
Adjust the FX level being added, compared to the
other channels playing in the main mix.
32. MAIN MASTER GRAPHIC EQ
This 7-band graphic equalizer adjusts the main mix
output. It affects the line-level outputs [19], as well as
the main speaker-level outputs if the internal amplifiers
are playing the main mix.
At the fully-down position, no effects are added, the
center U mark is unity gain, and 10 dB of effects gain is
available at the fully clockwise position.
Each slider allows you to adjust the level of its
frequency band, with up to 15 dB of boost or cut, and
no change in level at the center (0 dB) position. The
frequency bands are: 125, 250, 500, 1k, 2k, 4k, and 8kHz.
34. MAIN LEVEL
This knob controls the level of the main mix, and
affects the meters [36], main line-level outputs [19],
main sub out [18], and the main speaker-level outputs
if the internal power amplifiers are playing the main
mix. The level adjustment occurs before the EQ [32].
The EQ section comes after the main level [34], and
just before the main meters [36]. Therefore, as you ad-
just the EQ, you can keep an eye on the meters in case
you over-do it and take the levels into overload.
This gives you ultimate control over your audience.
Adjust it carefully, with your good eye on the meters to
check against overloading, and your good ear on the
levels to make sure your audience is happy.

The control does not affect the monitor 1 output [17],
monitor 2 output [15], or the internal power amp if it
is playing a monitor. (For stage monitor work, it is good
that the main mix level does not affect the monitor out-
puts, so they can be set up nicely and stay that way.)
The sliders will help you reduce frequencies in the
stage monitors that could cause feedback from nearby
microphones.
38. FX TO MON 1
The main mix signals are off with the level fully down,
the “U” marking is unity gain, and fully up provides 12
dB of additional gain. This additional gain will typically
never be needed, but once again, it’s nice to know it’s
there. The level control is stereo, as it affects both the
left and right of the main mix equally. This is the control
to turn down at the end of the song when you want “The
Great Fade-Out.”
This knob lets you control how much of the internal
effects is added to the mono monitor 1 mix. (The output
from the internal effects processor is stereo, summed to
mono and added to the mono monitor 1 mix.)
Adjust the FX level being added, compared to the
other channels playing in the monitor 1 mix.
At the fully-down position, no effects are added, the
center U mark is unity gain, and there is 10 dB of effects
gain at the fully clockwise position.
35. 100 Hz RUMBLE REDUCTION SWITCH
This switch is used to reduce the level of the frequen-
cy range below 100 Hz. It operates on the mono channel
1 to 6 mix, not the stereo channel mix.
39. MONITOR 1 LEVEL
This knob controls the level of the monitor 1 mix, and
affects the monitor 1 meter [41], mon 1 line-level out-
puts [17], and the monitor 1 speaker-level output if the
internal amplifier is playing the monitor 1 mix. The level
adjustment occurs before the monitor 1 EQ [37].
Use this to reduce the amount of low frequency
problems such as mic handling, stage rumble, bangs and
thumps in your main mix.
This switch is the audio-electronic equiva-
lent of taking anti-gas medication. It relieves
low-end rumble, and the whole room sounds
better.
This gives you ultimate control over your monitor 1
stage monitors. Adjust it carefully, with your good eye
on the monitor 1 meter [41] to guard against overload-
ing. Check that your band are happy with the levels. The
control does not affect the main mix level.
36. MAIN MIX METERS
The monitor 1 mix signals are off with the level fully
down, the “U” marking is unity gain, and fully up pro-
vides 12 dB of additional gain.
Developed from a harmless ex-NATO hamster
hypnotizer, these stereo meters show the level of the
left and right main mix, after it has passed through the
main level [34] and graphic EQ [32]. The top LEDs are
marked OL (overload), and you should adjust the levels
to avoid these coming on too often, if at all.
40. 100 Hz RUMBLE REDUCTION SWITCH
This switch is used to reduce the level of the frequen-
cy range below 100 Hz, playing in the monitor 1 mix. It
only affects the monitor 1 mix, and does not affect any
effects being added from the internal FX processor.
Please remember: Audio meter displays are just tools
to help assure you that your levels are “in the ballpark.”
You don’t have to stare at them (unless you want to).
Use this to reduce the amount of low frequency
problems such as mic handling, stage rumble, bangs and
thumps, that might affect the stage monitors.
37. MONITOR 1 MASTER GRAPHIC EQ
This 7-band, constant–Q graphic equalizer adjusts
the monitor 1 mix output. It affects the line-level mon 1
outputs [17], and the monitor 1 speaker-level output if
the internal amplifier is playing the monitor 1 mix.
41. MONITOR 1 METER
This meter shows you the level of the monitor 1 mix,
after it has passed through the monitor 1 level [39] and
graphic EQ [37].
Each slider allows you to adjust the level of its
frequency band, with up to 15 dB of boost or cut, and
no change in level at the center (0 dB) position. The
frequency bands are: 125, 250, 500, 1k, 2k, 4k, and 8kHz.
The top LED is marked OL (overload), and you should
adjust the levels to avoid this coming on too often, if at
all.
The EQ section comes after the monitor 1 level [39],
and just before the monitor 1 meter [41]. Therefore, as
you adjust the EQ, keep an eye on the meter in case you
over-do it and take the levels into overload. As with the
channel EQ, just take it easy.

fiers, so only loudspeakers connected to the
rear panel speaker-level outputs [3] will be

44. POWER AMP LIMITER LEDs
These independent LEDs turn on when
power amplifier channel A or B is being over-
loaded internally and its internal automatic
limiter (which is always in the signal path) is
actively working. The LED will pulse in time
with how much the limiter is being used in
the signal path.
If the Limiter LEDs come on and
stay on for more than a second or
two, it means the power supply
has overheated and the limiter is holding
the amp signal down to 1/4 power until the
power supply cools down enough to release
the limiter. If this happens, check there is
good ventilation around the mixer, and that
you are not cranking it too much. Also make
sure that your speakers are OK, and are not
less than 4 ohms impedance.

Stereo Effects Processor
42. PHANTOM SWITCH
The Mackie Running-Man 32-bit internal effects pro-
cessor is a mono-in, stereo-out effects processor, with 24
presets. It is fed by adjusting the FX/mon 2 control [22]
on each channel.
Press in this switch to add phantom power to all the
XLR microphone inputs of the mixer. This lets the mixer
send low-current DC voltage to the mic’s electronics
through the same wires that carry audio. The LED will
turn on as a reminder that phantom power is engaged.
The output from the processor can be added to the
main mix or monitor 1 mix by adjusting the FX to main
[33] and FX to mon 1 [38] controls.
Most modern professional condenser mics are
equipped for phantom power. Semi-pro condenser mics
often have batteries to accomplish the same thing.
“Phantom” owes its name to an ability to be “unseen”
by dynamic mics (Shure SM57/SM58, for instance),
which don’t need external power and aren’t affected by
it anyway.
This processor is also doing the calculations that hold
together the very fabric of the space-time continuum
(or at least the lunch-time portion of it).
45. FX/MON 2 SEND MASTER
Never plug single-ended (unbalanced) micro-
phones, or ribbon mics into the mic input
jacks if phantom power is on.
Use this knob to control the level of the signals going
into the internal effects processor. Adjust it carefully,
with your inner magical eye on the adjacent SIG/OL
LED [46] to prevent overloading the effects processor.
Do not plug instrument outputs into the mic
input jacks with phantom power on unless you
know for certain it is safe to do so.
It also affects the level going out of the FX/mon 2 line
level output [15], and the internal power amplifier if it
is playing monitor 2.

If you are not using Mackie speakers, then press it
anyway and listen for an improvement. The passive EQ
circuit is added just before the internal power ampli-
This dual-LED illuminates in green when the signal
level going into the effects processor is in a good operat-

The signals going into the processor are affected by
the channel FX/mon 2 controls [22], and the channel

[47] is out (post)). Check the LED if you alter these
controls.
49. PRESET SELECTOR, TAP DELAY and LED
Rotate this endless control to select one of the 24
preset effects. When you stop the rotation, that preset
will be loaded and become operational. The current pre-
set number is shown in the display [48]. The different

The FX/mon 2 control [22] on each channel samples
the channel signals after (post) the channel level
controls [27]. Any changes to the channel level will also
affect the level feeding the internal effects.

You can also set up an external effects processor by:
1. Muting the internal effects processor.
12 Gated Reverb
2. Connecting the FX/mon 2 output to an external
processor.
The knob also offers a tap delay function for the pre-
sets 17 to 24. This works as follows:
3. Returning the processed signal back to a free
mono or stereo channel line input.
1. Use the knob to select a preset from 17 to 24.
2. Press the knob in at least two times.
MON 2 SEND (PRE)
The DSP processor will calculate the time delay
between the last two pushes, and it will assign
this time interval to the echoes of the current
digital delay. The minimum tap delay is 50 ms
and the maximum is 500 ms. If taps are faster
than 50 ms, they will be set to 50 ms. If taps
are between 500 ms and 1 second, they will be
set to 500 ms. If taps are greater than 1 sec-
ond apart, they will be ignored. Try again a bit
faster.
In this position (in), the FX/mon 2 control on each
channel samples the channel signals before (pre) the
channel level controls.
This is ideal for using the FX/mon 2 output to feed a
stage monitor 2 setup, or to use the internal power amp
to power it (power amp mode switch [4] in the mon
1/mon 2 position).
You might want to mute the internal effects processor
with the FX mute switch [54].
3. The LED will flash in time with the new tap
delay time.
For more details, please see page 14, or the
rather lovely block diagram on page 29.
50. INTERNAL FX MUTE
When engaged, the internal effects processor is muted
at its output, and the adjacent LED will come on. The
footswitch connection [16] becomes disabled, and you
will not be able to use the footswitch to mute or unmute
the effects.
48. PRESET DISPLAY
This display shows the number of the currently
selected effects preset, as shown in the list of presets
silkscreened to the left of the display. Rotate the preset
selector knob to choose a preset.
If this switch is not engaged, then the internal effects
can be muted or unmuted with the footswitch.
The new preset will be loaded approximately 1/4 of
a second after you stop turning the knob, and will be
stored into the FX memory after about one second.
When the powered mixer is turned on, the FX section
will load up the last-used preset.
Congratulations! You’ve just read about all the fea-
tures of your powered mixer. Time for a cold one.

Appendix A: Service Information
If you think your powered mixer has a problem, please
check out the following troubleshooting tips and do your
Noise
best to confirm the problem. Visit the Support section of
of useful information such as FAQs and documentation.
You may find the answer to the problem without having
to send your mixer away.
•
Turn the channel levels down, one by one. If
the sound disappears, it’s either that channel or
whatever is plugged into it, so unplug whatever
that is. If the noise disappears, it’s from your
whatever.

Troubleshooting
•
The power LED should come on if the powered
mixer is connected to a suitable live AC mains
outlet, and the power switch is on. Check the
power cord is securely plugged in.
Bad Channel

Is phantom power required for your micro-
phones?
Bad Output
•
•
•
•
Is the main master level control turned up?
Are the graphic EQs set to reasonable levels?
Is the FX level going to the main mix, too high?
If it’s one of the main speaker-level outputs,
try unplugging its companion. For example, if
it’s the 1/4" left main output, unplug the left
Speakon output. If the problem goes away, it’s
not the powered mixer.
•
•
•
If a left speaker is presumed dead, connect it
to the right output instead. If the problem stays
with the same speaker, check the speaker wir-
ing, or any speaker fuses.
Unplug anything from the main line-level
outputs, or other line-level outputs, such as the
sub out, FX/mon 2 send, or mon 1 send, just in
case one of your external pieces has a problem.
If the power amp limiter lights come on often,
you may be overdriving the amplifiers. Check
the loudspeaker average load impedance is not
less than 4 ohms. Check the speaker wiring.

Appendix B: Connections
“XLR” Connectors
They must be separated into a left cord and a
right cord, which are plugged into the two mic
preamps.
Mackie mixers use 3-pin female “XLR” connectors on
all microphone inputs, with pin 1 wired to the grounded
(earthed) shield, pin 2 wired to the “high” (”hot” or
positive polarity) side of the audio signal and pin 3
wired to the “low” (“cold” or negative polarity) side of
the signal. See Figure A. This is all totally above board
and in full accord with the hallowed standards dictated
by the AES (Audio Engineering Society).
You can cook up your own adapter for a stereo
microphone adapter. “Y” two cables out of a
female 1⁄4" TRS jack to two male XLR plugs,
one for the Right signal and one for the Left.
•
Unbalanced Send/Return circuits. When wired
as send/return “Y” connector, a 1⁄4" TRS jack
or plug is connected tip to signal send (output
from mixer), ring to signal return (input back
into mixer), and sleeve to ground (earth).
Use a male “XLR”-type connector, usually found on the
nether end of what is called a “mic cable,” to connect to
a female XLR jack.

If you insert a TS (mono) 1⁄4" plug only partially (to
the first click) into a Mackie insert jack, the plug will
not activate the jack switch and will not open the insert
loop in the circuit (thereby allowing the channel signal
to continue on its merry way through the mixer).

This allows you to tap out the channel signal without
interrupting normal operation.
The recommended conductor gauges are listed for
AWG (American Wire Gauge) and Metric WG (Metric
Wire Gauge). Note that smaller AWG numbers = larger
conductors and smaller Metric WG numbers = smaller
conductors. The Metric WG is equal to ten times the
nominal conductor diameter in millimeters.
If you push the 1⁄4" TS plug in to the second click, you
will open the jack switch and create a direct out, which
does interrupt the signal in that channel. See Figure G.
NOTE: Do not overload or short-circuit the signal you
are tapping from the mixer. That will affect the internal
signal.
Longer Lengths
For cable lengths over 200 feet / 60 m at 8 ohms, and
over 100 feet / 30 m at 4 ohms, the conductor sizes need-
ed for less than 0.5 dB power losses are rarely practical
for physical and cost reasons. As a practical compromise
for these situations the recommended conductor gauge
is 10 AWG or 25 metric.
