3. Be sure that the volume of the input is the

same as it would be during normal use, or you

may have to readjust the gain in the middle of a

set. You can listen with headphones if you

carefully turn up the channel fader and

headphones level a little.

mixer right away. Before you do, please

read the safety instructions on page 2,

then read this page, and the rest later.

Zero the Mixer

4. The mono channel gain affects the mic and the

line inputs. The stereo channel gain adjusts the

stereo line inputs. Adjust as desired, and make

sure that the OL LED does not come on during

the loudest passages.

1. Turn down all knobs except the channel EQ and

pan knobs, and set all the faders fully down.

2. Set all channel EQ knobs, pan knobs, and the

graphic EQ sliders at their center detent.

3. Set all buttons to the “out” position.

4. Whistle a popular show tune.

Note: there are two hybrid channels [9/10 and

11/12 on the ProFX16 and 15/16 and 17/18 on

the ProFX22] that have both mono mic and

stereo line inputs. In these channels, the gain

control affects only the mic gain.

Connections

If you already know how you want to connect the

mixer, go ahead and connect the inputs and outputs

the way you want them. If you just want to get sound

through the mixer, follow these steps:

5. Repeat steps 1 to 4 for the other channels.

Instant Mixing

1. To get sound out of the speakers and into a

waiting world, engage a channel's L-R assign

switch, turn up that channel’s fader to the “U”

(unity gain) position, and slowly bring up the

main fader to a comfortable listening level.

1. Plug signal sources into the mixer, such as:

•

Microphones plugged into the mic inputs.

Engage phantom power if your mics need

it. Check the mic's user manual to be sure.

•

Line-level sources such as keyboards, drum

machines, or CD players plugged into the

line-level inputs.

2. Sing and play. You’re a star!

3. Bring in other channels as mentioned above.

Connect cords from the main outs to your

powered speakers or ampliﬁer.

USB

The USB connection allows you to play two channels

of audio from your computer, and to record the main

mix to your computer. This feature is explained more

thoroughly on pages 4, 9-10, 16 and 23.

3. Plug in the mixer’s power cord to a live AC

outlet and turn on the mixer.

4. If you have powered speakers, turn them on.

Otherwise, hook up your passive speakers to

your amp with speaker cables, and turn it on.

Adjust your powered speaker or ampliﬁer level

controls to however the manufacturer

Notes

For optimum sonic performance, the channel faders

and main fader should be set near the “U” (unity gain)

markings.

recommends. (This is usually all the way up.)

Set the Gain

Turn down all faders before making connections to

and from your ProFX mixer.

1. Plug something into an input. This could be an

instrument, you singing or speaking, or a line

level source such as a keyboard or CD player.

When shutting down the system, turn off ampliﬁers or

powered speakers ﬁrst. When powering up, turn them

on last. This will prevent the possibility of turn-on and

turn-off thumps heard in your speakers.

2. Engage the channel's PFL Solo switch to view

the input level via the main meters.

Save the shipping box and receipt! You may need

them someday.

Introduction

Awesomely unheard of features

Powerful on-board FX engine and four

individual compressors

In pursuit of the ultimate Mackie “do-it-all” live

sound mixer, we threw in the kitchen sink and packed

this bad boy with a full set of processors allowing you to

travel “rack free” while still making professional

sounding mixes.

USB Recording and Playback

The ProFX Series Mixers feature a 2x2 USB recording

and playback function. This means two signals may be

recorded simultaneously and a stereo mix returned to

the mixer for playback.

There is a switch in the master section labeled USB

OUT that allows for some powerful and ﬂexible routing.

The default switch conﬁguration allows the L-R mix to

be recorded for convenient stereo mixes of the show.

Or it routes subgroups 1-2 over the USB connection to

your favorite DAW software for an alternate 2-track

recording when the USB OUT switch is engaged.

For starters, we added our patented Running Man FX

processors (RMFX^™) featuring 16 “gig-ready” effects

right into the board. This does not include useless

effects such as “the warbler” or the “insanity delay”, but

rather a suite of quickly accessible and useable reverbs,

choruses and delays that make enhancing your mix a

breeze.

For playback, there is a switch in the master section

labeled 2-TRACK RETURN. This switch changes the

standard dual RCA inputs to main (tape, switch

disengaged) to stereo USB to main (USB, switch

engaged).This is an extremely convenient function for

playing music over the main mix from a computer. We

prefer to jam some Johnny 'The Man in Black' Cash in

between bands at the local rock clubs. But feel free to

play whatever you want, unless it's... ah, never mind, we

won't go there!

The ProFX16 and ProFX22 also have four single knob

compressors to stop the dynamic signals from poking

out of the mix. They are located on the last four mono

mic inputs so that the most critical signals (such as

vocals, snare drum, the occasional jaw harp or

mountain goats) may be addressed.

Bottom line? You have an awesome mixer with Mackie

sound quality, “built-like-a-tank” build quality and a

recording and processing feature set that is

Another cool feature of the ProFX is routing the

stereo USB return to the last stereo channel of the

mixer. This is a mighty ﬁne tool for a number of live and

recording uses. For example, playback through the

stereo channel allows the EQ to be utilized to sweeten

the sounds. It may also be used for overdubbing by

sending music to the musicians' headphones through

the auxes.

unparalleled. Congratulations... and happy mixing!

This diagram shows a mic'd up drum kit utilizing the ﬁrst seven channels of the mixer. Microphones are

connected to the next three channels for lead and background vocals. A guitar and bass are attached

to the next two channels' line-level inputs, each via a mono effects processor. An iPod docking station is

attached to the stereo tape inputs.

Mackie SRM450v2 powered speakers are connected to the left and right main output. Two of these

speakers are also set up as stage monitors and connect to the mixer's monitor output via a graphic EQ.

The aux mon controls of each channel allow you to create a stage monitor mix as desired. Headphones

are used for monitoring and a footswitch allows you to mute/unmute the internal effects as desired.

A laptop connects to the USB port and allows the 2-channel main mix of the performance to be

recorded to a DAW. Two channels of audio can also play from your computer to the main mix.

Connections

1. POWER CONNECTION

3. USB INPUT/OUTPUT

This is a standard 3-prong IEC power connector.

Connect the detachable linecord (included in the box

with your mixer) to the power receptacle, and plug

the other end of the linecord into an AC outlet. ProFX

Series mixers have a universal power supply that

accepts any AC voltage ranging from 100 VAC to 240 VAC.

No need for voltage select switches. It will work virtually

anywhere in the world. That’s why we call it a “Planet-

Earth” power supply! It is less susceptible to voltage sags

or spikes, compared to conventional power supplies, and

provides greater electromagnetic isolation and better

protection against AC line noise.

The built-in USB interface allows for some

powerful and ﬂexible routing. It is a 2x2 interface

allowing you to record two streams from the mixer, or to

input stereo playback from a computer and route it to

nearly any output or pair of outputs on the mixer.

The USB routing capabilities are as follows:

USB input TO the mixer - playback:

(1) Stereo channel 15/16 (on the ProFX16) and

21/22 (on the ProFX22) features a USB button, so one

may route computer output (such as iTunes^®) down the

last stereo channel of the board. This stereo signal may

then be EQ'd, sent to auxiliaries (i.e. to feed monitors,

headphones or effects) and is routable to mains and/or

subgroups via the fader routing features that are

available on all other channels. In short, this signal may

be sent to nearly any desired output or pair of outputs.

Additionally, the gain knob at the top of this channel

strip adjusts the USB input level to the mixer to achieve

an optimal signal level.

Disconnecting the plug’s ground pin is

dangerous. Don’t do it.

2. POWER Switch

Press the top of this rocker switch inwards to turn on

the mixer. The front panel power LED [36] will glow

with happiness...or at least it will if you have the mixer

plugged into a suitable live AC mains supply.

(2) The 2-Track Return section features a ﬂip switch,

so a “Tape” source (such as an iPod^®connected via RCA

cables) or the USB signal from a computer

Press the bottom of this switch to put the mixer into

standby mode. It will not function, but some circuits

are still live. To remove AC power, either turn off the AC

mains supply, or unplug the power cord from the mixer

and the AC mains supply.

(playing Windows Media Player^®ﬁles, for example) may

be routed to the main bus. This section also features an

input level adjustment for fading house music up and

down between bands, at a house of worship, or any other

event where this may be necessary.

As a general guide, you should turn on your

mixer ﬁrst, before any external power

ampliﬁers or powered speakers, and turn it off

last. This will reduce the possibility of any turn-on, or

turn-off thumps in your speakers.

Round Two Rejects

USB output FROM the mixer - recording, etc:

In the USB OUT section you may select either the

main mix (disengaged) or subgroups 1-2 (engaged)

from the conveniently titled USB OUT switch [49]. The

USB tap points for the subgroups are pre-fader and

signals will show up on the DAW dependent upon how

they are panned on the channels.

In other words, if subgroups 1 and 2 are used to sub-

mix drums and those drums have a stereo image

(e.g. overheads and toms pan according to desire), this

stereo image is retained in the DAW inputs (assuming

subgroup 1 is set to “L” and subgroup 2 is set to “R”).

Any adjustments made to the subgroup drum levels

during the show only pertain to the live show itself;

recording levels are not adjusted in the DAW unless they

are adjusted on the channels.

Smashing Guitar Man

Then, in the early 2000s, the graphic designers

decided to give the Running Man logo some color,

basically adding a theme to “spice it up”. This idea

didn't take off, so it was eventually shelved.

Likewise, it is possible to record the main mix to take

home a copy of the live show. These levels are also

pre-main fader. Therefore, levels may be mixed up or

down in the DAW later depending on the needs of the

recording versus the live show. The end result is that

fade-ins and/or fade-outs made during the show do not

affect recorded levels.

4. RUNNING MAN LOGO

The Running Man logo has been a point of controversy

since its inception.

The history of the Running Man is rather vague; nor

do we know what he is running from...or towards? Or

perhaps the man is running sound and not actually

running to or from anything or anyone. Here is what we

do know:

Rockabilly Man

Samba Man

Metal Man

Current status, the future and beyond:

Origins:

The current status is easy; it's as you see it today on

every Mackie product. Who knows what the future of

the Running Man logo holds? It's like the wheel analogy:

why ﬁx it if it ain't broke? The Running Man logo may be

seen all over the world, from the tiniest hole-in-the-wall

clubs to the biggest sized arenas, mid-sized theatres,

houses of worship, casinos and more!

It originated in the early '90s when founder Greg

Mackie decided that a logo was just as (if not moreso)

important than just the name. He stated that, “brands

are not recognized by name alone, but by their

accompanying logo...take a look at the logos of

McDonald's^®, Nike^®, Microsoft^®and Apple^®. You can

recognize those brands based on the logo alone.”

He quickly assembled a team to design what would

eventually become the Running Man logo. Here are a

few early examples that were eventually rejected:

Most modern professional condenser mics require

48V 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.

The ﬁrst two stereo channels [9/10 and 11/12 on the

hybrid channels, each with a mic input XLR jack [5]

and low cut switch [10]. In these channels, the gain

control [9] only affects the mic input. The stereo line

inputs are ﬁxed at unity gain.

This 20 dB of attenuation can be very handy when you

are inserting a hot signal, or when you want to add EQ

gain, or both. Without this “virtual pad,” there is more

chance of channel clipping.

8. INSERT

These unbalanced 1/4" jacks are for connecting

serial effects processors such as compressors,

equalizers, de-essers, or ﬁlters. The insert point is

after the gain control [9] and low cut ﬁlter [10],

but before the channel’s EQ [11-15] and level [23].

The channel signal can go out of the insert jack to

an external device, be processed and come back in

on the same insert jack.

10. LOW CUT Switch

All mono channels have a low-cut switch (often

referred to as a high-pass ﬁlter) that cuts bass

frequencies below 100 Hz at a rate of 18 dB per octave.

To do this requires a standard insert cable that must be

wired thusly:

We recommend that you use low-cut on every

microphone application except kick drum, bass guitar,

or bassy synth patches. These aside, there isn’t much

down there that you want to hear, and ﬁltering it out

makes the low stuff you do want much more crisp and

tasty. Not only that, but low-cut can help reduce the

possibility of feedback in live situations, and it helps to

conserve ampliﬁer power.

Another way to consider low-cut’s function is

that it actually adds ﬂexibility during live

performances. With the addition of low-cut,

Insert jacks may be used as channel direct outputs;

post-gain, and pre-EQ. See the connector section on

page 27 (ﬁgure G) showing three ways to use insert

you can safely use low equalization on vocals.

Many times, bass shelving EQ can really beneﬁt voices.

Trouble is, adding low EQ also boosts stage rumble, mic

handling clunks and breath pops from way-down low.

Applying low-cut removes all those problems, so you can

add low EQ without blowing your subwoofers.

“U” like Unity gain

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

CHANNEL EQUALIZATION (EQ)

All ProFX mono channels have 3-band EQ with

shelving hi, peaking mid with adjustable mid

frequency and shelving low. The stereo channels have

a peaking mid EQ control in addition to the shelving hi

and shelving low EQ controls.

level-wise if you choose to change a control’s settings.

9. GAIN

If you haven’t already, please read the level-setting

procedure on page 3.

Shelving means that the circuitry boosts or cuts all

frequencies past the speciﬁed frequency. For example,

the low EQ boosts bass frequencies below 80 Hz and

continuing down to the lowest note you never heard.

Peaking means that certain frequencies form a “hill”

around the center frequency.

The gain knobs adjust the input sensitivity of the mic

and line inputs. This allows signals from the outside

world to be adjusted to run through each channel at

optimal internal operating levels.

With too much EQ, you can really upset things.

We’ve designed a lot of boost and cut into

If the signal originates through the mic XLR jack,

there will be 0 dB of gain with the knob fully down,

ramping to 50 dB of gain fully up.

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. Equalize

subtly and use the left sides of the knobs (cut), as well

as the right (boost). If you ﬁnd yourself repeatedly using

a lot of boost or cut, consider altering the sound source,

such as placing a mic differently, trying a different kind

of mic, a different vocalist, changing the strings, or

gargling.

Through the 1⁄4" line input of channels 1-8 (ProFX16)

and channels 1-14 (ProFX22), there is 20 dB of

attenuation fully down and 30 dB of gain fully up, with

unity gain “U” at 12:00.

Through the 1⁄4" line input of channels 13/14 and

15/16 (ProFX16) and 19/20 and 21/22 (ProFX22), there

is 20 dB of attenuation fully down and 20 dB of gain fully

up, with unity gain “U” at 12:00.

The pan [18], mute [20] and channel fader [23] do

not affect the monitor output, but the other channel

controls will. The aux mon is pre-fader.

19. OL LED

This LED indicates the channel’s signal level after the

gain [9] and EQ controls [11-15], but just before the

channel’s level [23]. So even if the level is turned down,

you can see if the channel is being overloaded.

The overall output level may be adjusted with the aux

master mon knobs [42] and monitor 1's EQ tweaked

with the graphic EQ [37] if the main mix/mon 1 switch

[38] is pressed in. Internal FX may also be added to the

monitor mix with the internal FX to mon knobs [44].

The OL (overload) LED will come on when the

channel’s input signal is too high. This should be

avoided, as distortion will occur. If the OL LED comes

on regularly, check that the gain control [9] is set

correctly for your input device, and that the channel

EQ is not set with too much boost. The OL LED will

also illuminate when a channel's mute switch [20] is

engaged.

17. AUX FX

These knobs tap a portion of each channel's signal to

set up a nice FX mix feeding the internal FX processor,

and to feed external processors via the FX send [27].

The controls are off when fully turned down, deliver

unity gain at the center detent, and can provide up to

15 dB of gain turned fully up.

20. MUTE Switch

Mute switches do just what they sound like they do.

They turn off the signal by “routing” it into oblivion.

Engaging a channel's mute switch (almost) provides

the same results as turning the fader all the way down

(a pre-aux send is not affected by the channel fader,

but it is by the mute switch). Any channel assignments

to main mix, subgroup 1-2, or subgroup 3-4 will be

interrupted and all of the aux sends will be silenced

(both pre- and post-fader). The channel insert [8] will

continue to provide a signal when a channel is muted.

The OL LED [19] will illuminate when a channel's mute

switch is engaged.

The mute [20], channel fader [23] and other channel

controls affect the FX output, but pan [18] does not.

The aux FX is post-fader.

The FX signal reaching the internal FX processor

and the FX send output jack is the sum (mix) of all

the channels whose aux FX control is set to more than

minimum.

The overall output level may be adjusted with the aux

master FX knob [42]. FX are added to the main mix by

increasing the level of the internal FX to main L-R

knob [44]. Internal FX may also be added to the

monitor mix by increasing the level of the internal

FX to mon knobs [44].

21. ASSIGN Switches

Alongside each channel fader are three buttons

referred to as channel assignment switches. Used in

conjunction with the channel's pan knob [18], they

are used to determine the destination of the channel's

signal.

18. PAN

This control allows you to adjust how much of the

channel signal is sent to the left versus the right

outputs.

With the pan knob at the center detent, the left and

right sides receive equal signal levels (main mix L-R,

sub 1-2 and sub 3-4). To feed only one side or the other,

turn the pan knob accordingly.

With the knob panned hard left, the signal feeds

the main left, sub 1, or sub 3 busses, depending on the

setting of the assign switches [21]. With the knob

panned hard right, the signal feeds the main right, sub

2, or sub 4 busses, again dependent on the setting of the

assign switches.

If you are doing a mixdown to a 2-track, for example,

simply engage the main mix switch on each channel

that you want to hear, and they will be sent to the main

mix bus. If you want to create a group of certain

The pan control employs a design called “Constant

Loudness.” If you have a channel panned hard left (or

right) and then pan to the center, the signal is

attenuated about 3 dB to maintain the same apparent

loudness. Otherwise, it would make the sound appear

much louder when panned center.

channels, engage either the 1-2 or 3-4 switches instead

of the main mix, and they will be sent to the appropriate

subgroup faders. From there, the groups may be sent

back to the main mix (using the group assign switches

[54] above the group faders [55]), allowing you to use

the group faders as a master control for those channels.

If you are creating new tracks or bouncing existing

ones, you will also use the 1-2 and 3-4 switches, but not

the main mix switch. Here you do not want the groups

sent back into the main mix bus, but sent out, via the

sub out jacks [32], to your multitrack inputs.

25. COMPRESSOR

+20

Each of the last four mono channels of the ProFX

mixer has an in-line compressor circuit with a variable

threshold. This is very useful for compression of vocals,

and snare drums, for example, so you might consider

connecting your vocal and drum mics to these channels,

rather than one of the other channels.

+15

+10

When the incoming signal exceeds the threshold level

set by this knob, the signal level is automatically

compressed. This reduces the dynamic range and

reduces the chance of distortion due to overloading the

input signals.

-5

Dynamic range is the difference in level

between the quietest and loudest parts of a

song. A compressor “squeezes” 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; it is very useful for live

sound.

-10

-5

+10

+15

+20

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).

At the maximum compression, the threshold is set at

0 dBu, and the input to output relationship is

represented by the lower curve. If the input is –5 dBu

(that is, below the threshold), the output is –5 dBu. 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).

As an example, suppose the threshold is set to

maximum. 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

compression, and harder on the ears too.

The other blue curves represent in-between positions

of the compressor knob, with higher thresholds before

compression begins.

Outboard compressors often have controls such as

compression ratio, threshold, soft knee/hard knee,

attack 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 compressor, these

parameters are specially chosen to give you the best

overall performance.

The graph on this page shows the input signal level

going into the compressor, versus the output level

coming out of it. It is the typical graph to view when

compressors are discussed, and is just the kind of thing

our engineers like to discuss during the company

Christmas party*.

Adjust the threshold carefully, so your dynamic range

is still lovely, without distortion or overload during the

performance. Run through a few practice screams and

high-notes, and adjust the compression as required.

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.

* My High School math teacher, Mr. Marvin, thought that

graphs might come in handy for me one day. Finally!

Stage monitors allow the talented musicians in the

band to hear themselves clearly on stage. This can be a

good thing! The monitor mix may be carefully adjusted

in level using the aux mon controls [16]. These tap a

portion of each channel's signal to provide a 1/4" TRS

output here to feed external stage monitors. These

could either be passive stage monitors powered by an

external ampliﬁer, or powered stage monitors with their

own built-in ampliﬁer.

This 1/4" TRS line-level output may be used to feed

an external effects processor (FX), such as a nice

sound effect, or delay unit. The output from this jack

is an exact copy of what goes into the internal FX

processor, being the careful mix of all channels whose

aux FX control [17] is turned to more than minimum.

(The processed output of the internal FX does not

come out of this output, but is added internally to the

main mix or monitor mix.)

The monitor signal is the sum (mix) of all the

channels whose aux mon control is set to more than

minimum. If they want “more me and less Brian,” you

may turn up their channel's aux mon control, and turn

down Brian's. Of course, with two monitor buses and

two monitor outputs, anyone who wants “more Brian”

can have their own monitor mix.

The overall output level may be adjusted with the aux

master FX knob [42]. (This knob also affects the level

going into the internal FX.)

The output is “post-fader,” so any changes to the

channel faders [23] will also affect the level going to

the external processor.

The overall output level may be adjusted with the

aux master mon knob [42] and mon 1 may have its

EQ tweaked with the graphic EQ [37] if the main

mix/mon 1 switch [38] is pressed in. Alternatively, you

could add an external graphic EQ between this output

and your powered monitors. This will allow you to adjust

the EQ, and minimize the chance of feedback from

nearby microphones.

The processed output from the effects processor is

usually returned to the aux returns [29] or a spare

channel, and you may carefully mix the original

unprocessed channel (dry) and the processed channel

(wet). Altering the original channel fader increases

both the wet and dry signals and keeps them at the

same delicate ratio. For example, the reverb remains at

the same level relative to the original.

The monitor output is not affected by the main mix

fader [56] or the channel faders [23]. This allows you

to set up the monitor mix and level just right, and not

have it change when a channel fader or the main mix

fader is adjusted. This is known as “pre-fader.”

This 1/4" TRS connector is where to connect your

These four 1/4" jacks are usually patched to the

inputs of a multitrack deck or to secondary ampliﬁers

in a complex installation.

33. PHONES

If the internal effects have already been muted with

the internal FX mute switch [48], then the footswitch

before they are added to the main mix. (Solo signals

reaching the headphones are not affected by the

channel level or main level, therefore turn down the

phones level ﬁrst, as soloed channels may be loud.)

Level adjustment of the incoming signals is made with

the aux return controls [43].

You may also use these inputs to add any stereo

line-level signals to your main mix, so it could be

another line-level source, not just an effects processor.

The phones output follows standard conventions:

Tip = Left channel

Ring = Right channel

Sleeve = Common ground

If you are connecting a mono source, use the left

(mono) stereo return input, and the mono signals will

appear on both sides of the main mix.

can cause permanent hearing damage. Even

intermediate levels may be painfully loud

with some headphones. BE CAREFUL! Always turn the

phones level control [53] all the way down before

connecting headphones or pressing a solo switch, or

doing anything new that may affect the headphone

volume. Then turn it up slowly as you listen carefully.

The male XLR connectors provide a balanced

line-level signal that represents the end of the mixer

chain, where your fully mixed stereo signal enters the

real world. Connect these to the left and right inputs of

your main power ampliﬁers, powered speakers, or serial

effects processor (like a graphic equalizer or

compressor/limiter). The XLR outputs are 6 dB hotter

than the TRS outputs.

34. TAPE INPUTS / OUTPUTS

The stereo unbalanced RCA inputs allow you to play a

tape, CD player, iPod^®dock, or other line-level source.

The tape in jacks accept an unbalanced signal using

standard hi-ﬁ hookup cables.

The 1/4" TRS output connectors provide balanced or

unbalanced line-level signals. Connect these to the next

device in the signal chain like an external processor

(compressor/limiter), or directly to the inputs of the

main ampliﬁer. These are the same signal that appears

at the XLR main outputs, but 6 dB lower than the XLR

outputs. When the meters read “0”, these TRS outputs

are at 0 dBu.

The stereo unbalanced RCA outputs allow you to

record the main stereo mix onto a tape deck, hard disk

recorder, or automatic CD burner, for example. This

lets you make a recording for posterity/archive/legal

purposes whenever the band gets back together again.

The tape output is the stereo main mix, and it is not

affected by the main mix fader [56]. The output could

also be used as an extra set of main outputs for feeding

another zone.

31. CR OUT L/R

These 1/4" jacks are usually patched to the inputs of

35. 48V PHANTOM POWER Switch

Most modern professional condenser mics require

48V 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.

This green LED will illuminate when the mixer is

turned on, as a reminder of how on it really is. If it is

not on, then it is off, and the mixer becomes a rather

nice weight for keeping your morning newspaper from

blowing away in the wind.

If it does not turn on, make sure the power cord is

correctly inserted at both ends, the local AC mains

supply is active, and the power switch [2] is on.

37. STEREO GRAPHIC EQ

This 7-band graphic equalizer adjusts the main mix

output. It affects the line-level outputs [30, 31], but

not the headphones [33], tape outputs [34], or the

USB output [3]. This EQ may be used for a monitor mix

instead of the main mix if the main mix/mon 1 switch

[38] is engaged. It may also be quickly bypassed using

the EQ in/bypass switch [39].

Press this switch in if your microphone requires

phantom power. (Always check the position of this

switch before connecting microphones.) A red LED just

to the right of the switch will illuminate to indicate that

phantom power is active. This is a global switch that

affects all mic channels' XLR jacks at once.

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, 1 k, 2 k, 4 k

and 8 kHz.

Never plug single-ended (unbalanced)

microphones, or ribbon mics into the mic

input jacks if phantom power is on. 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. Be sure the main mix fader [56] is

turned down when connecting microphones to the mic

inputs when phantom power is turned on, to prevent

pops from getting through to the speakers.

The EQ section comes before the main mix fader [56]

and meters [40]. 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

boosting the desired range. You may use it to reduce the

level of some frequency bands where feedback occurs.

38. MAIN MIX / MON 1 Switch

This switch allows you to choose if the stereo graphic

EQ [37] is used for the stereo left and right main mix

or if it is used for monitors. For example, there may be

times when the graphic EQ may be used wisely in the

monitor mix to reduce feedback in the monitors from

nearby microphones. Note that this does not affect the

monitors 2 send, only the monitors 1 output.

The left meter's 0 dB LED is labeled “level set” to

show where the level should be when adjusting a

channel’s gain [9] in the solo mode.

When 0 dBu (0.775 V) is at the main left and right

TRS outputs [30], it shows as 0 dB on the meters.

You can get a good mix with peaks ﬂashing anywhere

between –20 and +10 dB on the meters. Most ampliﬁers

clip at about +10 dBu, and some recorders aren’t so

forgiving either. For best real-world results, try to keep

your peaks between “0” and “+6.” Remember, audio

meters 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).

39. EQ IN / BYPASS Switch

This switch allows you to quickly engage or disengage

the stereo graphic EQ [37]. This may be used for quick

checks of your EQ settings, or to shorten the signal path

if you do not need to use the EQ.

41. RUDE SOLO LED

These peak meters are made up of two columns of

twelve LEDs, with three colors to indicate different

ranges of signal level, trafﬁc light style. They range from

the top.

This large red LED ﬂashes when one or more solo

switches are engaged [22]. This acts as a reminder that

what you hear in the control room and headphones

is the soloed channel(s). If you forget that you are in

solo mode, you can easily be tricked into thinking that

something is wrong with your mixer. Hence, the rude

solo light. Please forgive its rudeness, it is only trying to

help, and wants to be your friend.

When a channel is soloed, the right meter shows no

reading, and the left meter shows the level of that

channel’s signal level, pre-fader.

DAW software for an alternate 2-track recording.

This important “take-a-break” switch quickly mutes

all the microphones and line-level inputs when the band

is between sets. This will prevent protestors or rogue

karaoke singers from storming the stage at the interval.

55. SUB 1-4 FADERS

As you might expect, these faders control the levels of

the signals sent to the sub outs [32]. All channels that

are assigned to subs, not muted, and not turned fully

down will appear at the sub outs.

The sub signal is off when its fader is fully down, the

“U” marking is unity gain, and fully up provides 10 dB

additional gain. Remember that if you are treating two

subs as a stereo pair, sub 1 and 2 for example, make sure

that both sub faders “ride” together to maintain the left/

right balance.

When a channel's solo switch [22] is engaged, any

existing selection is replaced by the solo signal,

appearing at the control room outputs [31], phones

[33] and at the left meter [40]. The audible solo levels

are then controlled by the control room knob [53]. The

solo levels appearing on the meters are not controlled

by the control room knob [53] - you would not want

This stereo fader allows you to adjust the levels of the

main mix signals sent to the XLR and 1/4" main

line-level outputs [30] and the tape outputs [34].

Solo signals reaching the headphones and

monitor outputs are not affected by the

channel level or main level; therefore, turn

not want to try that with seven hands or seven ﬁngers,

so just unassign these channels from the main mix and

it’s there. The fader is stereo, as it affects both the left

control to slowly bring down at the end of a song (or

If you engage just one assign to main mix button per

main mix, engage both the assign to main mix left and

right buttons. The signal will be sent to both sides, and

reduced in level by 3 dB like a pan pot, so the overall

level is the same, whether the group is assigned to main

If you think your mixer has a problem, please check

out the following troubleshooting tips and do your best

Noise

to conﬁrm the problem. Visit the Support section of our

website (www.mackie.com) where you will ﬁnd lots of

useful information such as FAQs, documentation and

any updated PC drivers etc. You may ﬁnd the answer to

the problem without having to send your mixer away.

•

Turn the channel gains 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.

Power

Troubleshooting

•

The power LED should come on if the mixer is

connected to a suitable live AC mains outlet,

and the power switch is on. Check to make sure

that the power cord is securely plugged in.

Bad Channel

•

Is the channel EQ set up nicely?

Is the channel gain set correctly?

Is the channel level up enough?

Is the channel OL led on?

Repair

For warranty service, refer to the warranty

information on page 35.

Is the channel pan set in the middle?

Try the same source signal in another channel,

Time, to explain the problem. Tech Support will tell you

where the nearest factory-authorized service center is

located in your area.

Are the EQs set to reasonable levels?

Are any aux returns maxed out?

Unplug anything from the other line-level

outputs, such as monitor out, just in case one of

your external pieces has a problem.

•

Make sure that you are not overdriving your

ampliﬁers. Check the loudspeaker average load

impedance is not less than the minimum your

ampliﬁer can handle. Check the speaker wiring.

XLR Connectors

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).

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.

¹⁄4" TS Phone Plugs and Jacks

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.

TS stands for Tip-Sleeve, the two connections

available on a mono 1⁄4" phone jack or plug. See

When wired for stereo, a 1⁄4" TRS jack or plug is

TRS Send/Receive Insert Jacks

Mackie’s single-jack inserts are the three-conductor,

TRS 1⁄4" phone type. They are unbalanced, but have

(return) signals in one connector. See Figure F.

Figure F

The sleeve is the common ground (earth) for both

signals. The send from the mixer to the external unit is

carried on the tip, and the return from the unit to the

mixer is on the ring.

Using the Send-only on an Insert 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.

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.
