Introduction

Another important feature you’ve come to expect

from Mackie is pristine sound quality, and Big Knob

is no exception. This is studio-quality gear, and we

made sure the audio signal suffers no degradation

by passing through Big Knob. You can connect this

baby between your expensive DAW and your really

expensive studio monitors with no reservations.

Big Knob will pass the test!

Thank you for choosing the Mackie Big Knob,

your signal routing and monitoring solution for your

DAW-based studio. Big Knob provides a control

room matrix and the basic features of an expensive

mixer, but tailored for the requirements of your

DAW (Digital Audio Workstation) environment.

These features include selecting up to four separate

stereo input sources, monitoring through three dif-

ferent speakers for A/B/C comparisons, providing a

separate headphone mix and a studio output for the

talent, and a built-in talkback mic for slate-to-tape

and headphone cueing. In other words, it gives you

everything you need from a mixer, without the stuff

you don’t need!

Big Knob is part of the growing family of Mackie

computer recording products. Visit our website

(www.mackie.com) to learn more about these prod-

ucts and the solutions to your audio and recording

needs that Mackie has to offer, or pick up a catalog

at your nearest Mackie dealer.

Zero the Controls

1. Turn off the POWER switch on the rear panel.

Getting Started

The following steps will help you set up your Big

Knob and get the levels adjusted correctly. Once you

have made the connections and adjustments, refer to

the Features section for more in-depth information

about each input, output, switch, and control knob.

2. On the front panel, turn the Big VOLUME Knob

and all the LEVEL controls all the way down

(counterclockwise).

3. Set all the switches to the up position (front

and rear panels).

Most of the inputs and outputs on Big Knob

have either a trim control or a level switch

labeled –10 dB and +4 dB. This actually

4. On the rear panel, turn all the trim controls all

the way down (counterclockwise).

comes from two standard operating levels

that have evolved in the audio industry:

–10 dBV consumer level and +4 dBu pro-

fessional level. Most consumer equipment with RCA

connectors operate at the –10 dBV level, while most

professional equipment with 1/4-inch phone jacks

or XLR connectors operate at the +4 dBu level.

As you might expect, the +4 dBu level is higher

(louder) than the –10 dBV level, so it is important to

match the input and output levels of Big Knob to the

equipment you have connected to it. For a Big Knob

input, the –10 dB setting accepts a smaller signal

and provides more gain than the +4 dB setting. For

a Big Knob output, the –10 dB setting produces a

smaller signal than the +4 dB setting.

Connections

1. Connect the supplied detachable power cord to

the AC socket on the rear panel of Big Knob.

Set the AC SELECT switch

For Monitoring:

2. Connect the audio outputs (stereo mix) from

your DAW’s audio interface to the two DAW MIX

input jacks on the rear panel of Big Knob.

3. Connect the MONITOR A output jacks on the

rear panel of Big Knob to a pair of active studio

monitors (or the inputs of an ampliﬁer that is

powering a pair of passive studio monitors).

These will be located at your mixing position.

If you know whether the inputs to the active

studio monitors (or ampliﬁer) accept a –10 dBV

(consumer) or +4 dBu input level, set the trim

control above the MONITOR A output jacks

to the appropriate position. Otherwise, leave it

at the –10 dBV position for now. You can con-

nect additional speakers to the MONITOR B

and MONITOR C output jacks so you can hear

your mix through different types of speakers.

Set the Levels

1. With everything off, turn on Big Knob’s POWER

switch ﬁrst.

2. Turn on all other external power ampliﬁers, active

speakers, and headphone ampliﬁers.

3. Start playback on your DAW and play some-

thing you’ve already recorded (or a demo track).

You want to be able to listen to it over the moni-

tor speakers connected to Big Knob.

4. Press the DAW MIX button in the INPUT

SOURCE SELECT section on the front panel.

The LED above the DAW MIX button should

light.

4. If you have a separate studio for recording,

connect the STUDIO OUTS to a pair of active

studio monitors (or the inputs of an ampliﬁer that

is powering a pair of passive studio monitors).

These will be located in studio for the talent.

Set the trim control above the STUDIO OUTS

output jacks to the appropriate position, or leave

it at the –10 dBV position if you’re not sure.

5. Press the MONITOR A button in the MONITOR

SELECT section on the front panel. The LED

above the MONITOR A button should light.

6. If you know whether your DAW’s audio inter-

face output is at a –10 dBV level (consumer) or a

+4 dBu level (pro), set the +4/–10 level switch

for the DAW MIX inputs to the appropri-

ate position. If you don’t know, leave it out (in

the +4 dBu position). We can change it later if

we need to.

5. If you have a headphone distribution ampliﬁer

for monitoring while recording, connect the

PHONES AMP output jacks to the inputs

of the headphone amp. Set the +4/–10 level

switch above the PHONES AMP output

jacks to the appropriate position, or leave it at

the –10 position (pushed in) if you’re not sure.

7. Slowly turn up the trim control for the DAW

MIX input until you see the meters on the

front panel lighting and dancing happily. Adjust

the control until the meters are lighting the “0”

LED regularly. You want the “+8” LED to light

only occasionally, and the “OL” LED to not light

at all.

For Recording

6. Connect the 2-TRACK A outputs to the line-

level inputs of any recording device, like a DAT

or cassette recorder. This allows you to record

from your DAW to the recorder. Set the +4/–10

level switch above the 2-TRACK A output

jacks to the appropriate position, or leave it at

the –10 position (pushed in) if you’re not sure.

8. If you can’t adjust the trim control far enough

to get the signal level up to the 0 and +5 LEDs

on the meter, turn the trim control all the way

down, push in the +4/–10 level switch for the

DAW MIX input, and slowly turn up the trim

control again. Now the signal should be strong

enough to get the 0 and +5 LEDs to light.

7. Connect the line-level outputs from the DAT or

cassette recorder to the 2-TRACK A inputs.

8. Connect the DAW output jacks on the rear

panel of Big Knob to the stereo inputs of your

DAW’s audio interface. This allows you to

record from the 2-TRACK recorder back to your

DAW. Set the +4/–10 level switch above the

DAW output jacks to the appropriate position,

or leave it at the –10 position (pushed in) if

you’re not sure.

9. Slowly turn up the Big Knob VOLUME

control. You should begin to hear playback from

your DAW through your studio monitor speak-

ers. Adjust the VOLUME control to a comfort-

able listening level. If it seems like you have to

turn up the VOLUME control all the way to hear

the monitor speakers, turn down the VOLUME

control and check to see if the trim control

11. Slowly turn up the STUDIO OUTS LEVEL

control on the front panel. You should begin

to hear playback from your DAW through your

studio monitor speakers. Adjust the STUDIO

OUTS LEVEL control to a comfortable listening

level. If it seems like you have to turn up the

LEVEL control all the way to hear the studio

monitor speakers, turn down the LEVEL control

and check to see if the trim control above the

STUDIO OUTS jacks is in the –10 dB position

(counterclockwise). If it is, turn the control

up to the +4 dB position and then turn up the

LEVEL control. Now it should get louder, faster.

CAUTION: See “A Cautionary Note” on the next

page to avoid creating a feedback loop through

the 2-TRACK inputs and outputs.

15. Push in the 2-TRACK A button in the INPUT

SOURCE SELECT section on the front panel

and turn off the DAW MIX button. Slowly turn

up the trim control for the 2-TRACK A input

until you see the meters on the front panel

light. Adjust the control until the meters are

lighting the “0” LED regularly. You want the

“+8” LED to light only occasionally, and the

“OL” LED to not light at all.

12. If you have a headphone distribution ampliﬁer

connected to the PHONES AMP outputs, you

should be able to turn up the volume for each

headphone connected to the headphone ampliﬁ-

er and hear playback from the DAW. If it seems

like you’re not getting enough volume from the

headphone ampliﬁer, turn down all the head-

phone volume controls on the headphone ampli-

16. Make sure the inputs to the DAW are selected

for recording. Start recording and the playback

from the 2-TRACK A input to Big Knob should

be recording in the DAW application. If it seems

like you’re not getting enough volume from the

2-TRACK playback, check to see if the +4/–10

level switch above the DAW output jacks

is in the –10 dB position (pushed in). If it is,

switch it to the +4 position. This will provide a

stronger signal to send to your DAW.

Big Knob Features

Front Panel

INPUT SOURCE SELECT Section

PHONO

Turns on the signals connected to the PHONO ste-

reo inputs.

These buttons turn on or off the four input signals

connected to Big Knob. Any combination of the four

inputs can be turned on at the same time, as indi-

cated by the red LEDs above the buttons.

INPUT METERS

These six segment meters show the signal level of

the currently selected stereo source(es). The scale

of the six segments of the meter is:

–24, –8, –4, 0, +8, and OL (Overload), where “0” is

referenced to +4 dBu.

When selected, these input sources are routed to the

MONITOR A, B, and C stereo outputs, the 2-TRACK A

and 2-TRACK B stereo outputs, the DAW stereo

outputs and, when the PHONES/STUDIO OUTS

SOURCE button is out (INPUT SOURCES), to the

PHONES AMP and STUDIO OUTS stereo outputs, and

to the PHONES 1 and 2 outputs on the front panel.

VOLUME

This Big Knob adjusts the volume of the selected

input source going to the selected speaker outputs

(MONITOR A, B, and C). The VOLUME knob ONLY

affects the volume level of the monitor outputs (A,

B, and C). It does not affect the volume of the signal

going to other outputs, such as the headphone out-

puts, 2-TRACK outputs, or DAW outputs.

A Cautionary Note: When you

have a 2-track recording device

connected to both the inputs and

the outputs on Big Knob, you run

the risk of creating a feedback

loop. If the recording device is in record, record

pause, or input monitor mode, the signal can go

from the 2-TRACK outputs through the recording

device and back into the 2-TRACK inputs, creating

a circular loop that results in a terrible howl.

You must remember to turn off the 2-TRACK

INPUT SOURCE SELECT button when recording

to your 2-track recorder!

The VOLUME knob ranges from OFF (∞) to +10 dB

of gain (MAX)

MONO

Pressing this button combines the stereo signal

into a monophonic signal at the MONITOR A, B,

and C outputs. The left and right input signals are

summed and the mono signal is output at both the

left and right outputs. This lets you check for phase

problems in the stereo signal when played over a

monophonic system.

DAW MIX

Turns on the signals connected to the DAW MIX

stereo inputs.

2-TRACK A

MUTE

Turns on the signals connected to the 2-TRACK A

stereo inputs.

Press this button to mute the signal going to the

MONITOR A, B, and C outputs.

out affecting the speaker level you have set.

These 1/4-inch TRS connectors output an ampli-

ﬁed stereo signal of either the DAW PHONES MIX

INPUT or the INPUT SOURCES

depending on the position of the PHONES/STUDIO

OUT SOURCE switch described below.

Note: Like the Big Knob VOLUME control, the

MONO, MUTE, and DIM buttons ONLY affect the

MONITOR A, B, and C outputs. These buttons have

no effect on the currently selected source(s) as they

are routed to the other various outputs.

PHONES 1 and 2 Level Control

These rotary knobs control the volume of the stereo

signal at the PHONES 1 and 2 headphone connec-

tors. The same signal appears at both headphone

outputs, but the volumes are adjusted independently

with these level controls.

POWER LED

This cool blue LED lights when the POWER switch

is turned on and Big Knob is receiving AC power. It

lets you know that Big Knob is turned on, even if no

other buttons are pressed that would light up their

associated red LED.

Note: Turn down the PHONES

LEVEL controls before plugging

in your headphones. The PHONES

outputs are designed to drive

headphones to a very loud level,

MONITOR SELECT

so it is best to start with the LEVEL controls turned

all the way down and then turn them up SLOWLY to

a comfortable listening level. In fact, starting right

now, get in the habit of turning down the PHONES

LEVEL controls when you are done using your

headphones so you don’t plug them in later and ac-

cidentally blow out your ears!

Press this button to route the currently selected

input source(s) to the MONITOR A output jacks.

Press this button to route the currently selected

input source(s) to the MONITOR B output jacks.

PHONES/STUDIO OUT SOURCE Button

This button affects the stereo signal going to:

• Both headphone outputs (PHONES 1 and 2) on

the front panel

Press this button to route the currently selected

input source(s) to the MONITOR C output jacks.

When the button is down (PHONES MIX INPUT),

the STUDIO/PHONES outputs are fed the signal

from the DAW PHONES MIX INPUT jacks on the

rear panel. In this position, the recording engineer

listens to the “real” mix coming from the DAW

(DAW MIX INPUT), but the talent can listen to an

alternate and specialized mix coming from the DAW

using a stereo aux send routed to another pair of

outputs, which is connected to the DAW PHONES

MIX INPUT on Big Knob and routed to the STUDIO/

PHONES outputs with the PHONES/STUDIO OUT

SOURCE button.

The TALKBACK TO PHONES/STUDIO button routes

the talkback signal to all of these outputs no matter

how the PHONES/STUDIO OUTS SOURCE selec-

tor button is set. This means that all the headphones

and studio outputs will hear the talkback signal

whether they are getting program material from the

This button turns the signal path on and off going to

the STUDIO OUTS jacks on the rear panel. When

the button is pushed in (ON), the red LED above the

for professional equipment operating at the +4 dBu

standard, and use the –10 dB setting for consumer

equipment operating at the –10 dBV standard.

2-TRACK A Level Switch

This two-position switch sets the input level of the

2-TRACK A inputs to either +4 dB (balanced input)

or –10 dB (unbalanced input). Use the +4 dB setting

for professional equipment operating at the +4 dBu

standard, and use the –10 dB setting for consumer

equipment operating at the –10 dBV standard.

DAW MIX Trim Control

This control adjusts the input sensitivity of the

incoming DAW MIX signal by 10 dB (unity at center

detent). This allows you to precisely ﬁne tune the

incoming level of the DAW MIX input so it matches

the signal level of other incoming 2-track sources.

2-TRACK A Trim Control

This control adjusts the input sensitivity of the

incoming 2-TRACK A signal by 10 dB (unity at

center detent). This allows for precise level matching

between the various incoming 2-track sources, which

often do not have output level controls of their own.

PHONO

These stereo RCA unbalanced inputs are fed by the

outputs of a turntable with a moving-magnet cartridge

(MM). These inputs have a built-in precision RIAA

preampliﬁer that provides the equalization and gain

required for a phono-level signal to return it to a

proper line-level signal.

2-TRACK B Inputs

These stereo 1/4-inch balanced/unbalanced inputs

are fed by the outputs of the second external 2-track

recorder. If a mono signal is plugged into the LEFT

input only, it is automatically routed to both LEFT

and RIGHT inputs.

This allows you to playback vinyl records and dub

them to a 2-track recorder, as well as send the

phono signal to the input of the DAW for archiving/

restoration/CD burning.

2-TRACK B Level Switch

Note: Two RCA shorting plugs are provided, which

should be plugged into the PHONO inputs when they

are not being used. This terminates the inputs and

reduces the noise ﬂoor should you accidentally push

in the PHONO INPUT SOURCE SELECT button.

This two-position switch sets the input level of the

2-TRACK B inputs to either +4 dB (balanced input)

or –10 dB (unbalanced input). Use the +4 dB setting

for professional equipment operating at the +4 dBu

standard, and use the –10 dB setting for consumer

equipment operating at the –10 dBV standard.

PHONO Trim Control

This trim control adjusts the input sensitivity of

the incoming PHONO signal by 10 dB. This allows

you to precisely ﬁne tune the incoming level of the

PHONO input so it matches the signal level of other

incoming 2-track sources.

2-TRACK B Trim Control

This control adjusts the input sensitivity of the

incoming 2-TRACK B signal by 10 dB (unity at

between the various incoming 2-track sources, which

often do not have output level controls of their own.

The PHONO input does not need a +4/–10 level

switch since a phonograph is always at a consumer

signal level, unlike tape decks and soundcards,

which could be –10 or +4, depending on the model.

DAW MIX

These stereo 1/4-inch balanced/unbalanced in-

puts are fed by the master mix output of the DAW,

usually the DAW outputs 1-2. If a mono signal is

plugged into the LEFT input only, it is automatically

routed to both LEFT and RIGHT inputs.

PHONO Grounding Lug (GND)

This small grounding lug allows you to connect the

grounding wire from an attached turntable. This

prevents ground loops and hum from showing up in

the phono source’s audio signal.

DAW MIX Level Switch

This two-position switch sets the input level of the

DAW MIX inputs to either +4 dB (balanced input) or

–10 dB (unbalanced input). Use the +4 dB setting

DAW PHONES MIX INPUT

These stereo 1/4-inch balanced/unbalanced inputs

allow connection of a second stereo mix from the

DAW for a custom headphone mix.

and STUDIO OUTS

Note: The overall level of the MONITOR A, B, and C

OUTPUTS is controlled by the Big VOLUME Knob

on the front panel.

DAW PHONES MIX Level Switch

This two-position switch sets the input level of the

DAW PHONES MIX inputs to either +4 dB (bal-

anced input) or –10 dB (unbalanced input). Use the

+4 dB setting for professional equipment or sound-

cards operating at the +4 dBu standard, and use the

–10 dB setting for consumer equipment or sound-

cards operating at the –10 dBV standard.

2-TRACK A OUTPUTS

These stereo 1/4-inch balanced/unbalanced outputs

connect to the inputs of the ﬁrst external 2-track

recorder. This could be a DAT deck, cassette deck,

reel-to-reel recorder, etc. The signal at these out-

puts is whatever source is selected with the INPUT

SOURCE SELECT buttons on the front panel.

TALKBACK FOOTSWITCH

2-TRACK A Level Switch

This 1/4-inch TS connector accepts a standard

momentary footswitch (normally open), or a mo-

mentary handheld switch such as the Switchcraft

ED900. This allows a producer standing at a remote

location to activate the talkback circuit and commu-

nicate with recording talent.

This two-position switch sets the level of the 2-TRACK

A outputs to either +4 dB (out) or –10 dB (pushed in).

Use the +4 dB setting when connecting to balanced

inputs on professional equipment operating at the

+4 dBu standard, and use the –10 dB setting when

connecting to unbalanced inputs on consumer equip-

ment operating at the –10 dBV standard.

When an external switch is connected and goes from

its “normally open” position to its “momentary closed”

position, the front panel TALKBACK TO 2-TRACKS

2-TRACK B OUTPUTS

and TO PHONES/STUDIO

buttons both activate,

their LEDs illuminate, and the talkback circuit is

activated just as if someone had physically pressed

these two buttons. See “Appendix B: Connections” for

a wiring diagram of the footswitch connection.

Works as described above for the 2-TRACK A OUTPUTS.

2-TRACK B Level Switch

Works as described above for the 2-TRACK A level

switch.

OUTPUTS

DAW OUTPUTS

The following outputs are fed by the “control room

bus.” This is the signal path fed from the inputs cur-

rently selected with the INPUT SOURCE SELECT

buttons and routed through the Big VOLUME Knob.

These stereo 1/4-inch balanced/unbalanced outputs

connect to a pair of inputs on the DAW audio interface.

DAW Level Switch

MONITOR A OUTPUTS

This two-position switch sets the level of the DAW out-

puts to either +4 dB (out) or –10 dB (pushed in). Use

the +4 dB setting when connecting to balanced inputs

on professional equipment or soundcards operating at

the +4 dBu standard, and use the –10 dB setting when

connecting to unbalanced inputs on consumer equip-

ment or soundcards operating at the –10 dBV standard.

These stereo 1/4-inch balanced/unbalanced outputs

connect to the ﬁrst set of external speakers. You

can connect these outputs to self-powered speakers,

or to a power ampliﬁer driving passive speakers.

MONITOR A Trim Control

This trim control adjusts the sensitivity of the

MONITOR A output signal. Use the +4 dB setting

when connecting to balanced inputs on professional

equipment operating at the +4 dBu standard, and

use the –10 dB setting when connecting to unbal-

anced inputs on consumer equipment operating

at the –10 dBV standard. The trim control can be

adjusted to any setting between the +4 and –10

positions if necessary to precisely match the levels

among the MONITOR A, B, and C outputs.

By allowing balanced or unbalanced operation, as well

as –10 or +4 operation, on an individual basis, you can

connect any combination of professional or consumer

2-track recorders and DAW soundcards that you have

available in your arsenal of audio recording equipment.

Note: All three of the above out-

puts (2-TRACK A, 2-TRACK B, and

DAW) produce the signal selected

by the INPUT SOURCE SELECT

buttons on the front panel. These

MONITOR B OUTPUTS

outputs require no variable level output controls

(aside from the +4/–10 switches), since the con-

nected 2-track recorders and DAW inputs typically

have their own variable input level controls.

Works as described above for the Monitor A path.

PHONES AMP and STUDIO OUT

STUDIO OUTS

The PHONES AMP and STUDIO OUTS have the

option of being fed signal by the currently selected

INPUT SOURCE SELECT buttons (thus mirroring

the mix being heard by the engineer) or the signal

connected to the DAW PHONES MIX INPUT con-

nectors (thus providing a separate unique monitor-

ing mix for the talent).

Connect these stereo 1/4-inch balanced/unbalanced

connectors to a pair of active monitors (or to an

ampliﬁer and passive monitors) in the studio per-

formance space. This allows the performers to hear

playback without having to use headphones, and

allows the control room engineer to communicate

to the performers through the talkback system. The

STUDIO OUTS level is controlled by the STUDIO

OUTS LEVEL control on the front panel.

This allows the engineer to listen to his or her own

master mix in the control room, while allowing the

talent to listen to a customized headphone mix at

the same time through the PHONES 1 or 2 outputs

on the front panel or through an external headphone

amp connected to the PHONES AMP OUTPUT on

the rear panel, as well as the studio monitor outs

(STUDIO OUTS). The choice of which stereo signal

(current source or headphone mix input) is heard is

determined by the PHONES/STUDIO OUTS SOURCE

select button on the front panel.

STUDIO OUTS Trim Control

This trim control adjusts the sensitivity of the

STUDIO OUTS signal. Use the +4 dB setting when

connecting to balanced inputs on professional equip-

ment operating at the +4 dBu standard, and use the

–10 dB setting when connecting to unbalanced inputs

on consumer equipment operating at the –10 dBV

standard. Although the trim control is typically set to

one side or the other, it can be adjusted to any setting

between the +4 and –10 positions if necessary.

PHONES AMP OUTPUTS

Connect these stereo 1/4-inch balanced/unbalanced

connectors to an external multi-headphone ampliﬁ-

er. This allows you to connect multiple sets of head-

phones for the talent. The PHONES AMP OUTPUT

level is not affected by the Big VOLUME Knob or

the headphone level controls on the front panel. The

headphone ampliﬁer should have its own individual

volume controls for the headphones.

AC Socket

Connect the included detachable power cord to

this AC socket (2-prong IEC connector) on the rear

panel. Make sure the AC SELECT switch is set to

the correct AC voltage (see AC SELECT Switch

below).

POWER Switch

PHONES AMP Level Switch

This rocker style switch turns power on and off for

Big Knob.

This two-position switch sets the level of the PHONES

AMP outputs to either +4 dB (out) or –10 dB (pushed

in). Use the +4 dB setting when connecting to balanced

inputs on professional equipment operating at the

+4 dBu standard, and use the –10 dB setting when

connecting to unbalanced inputs on consumer equip-

ment operating at the –10 dBV standard.

AC SELECT Switch

Set this switch to the 100-120V position for 100 VAC

and 120 VAC power, and to the 220-240V position for

220 VAC and 240 VAC power.

Appendix A: Service Information

Warranty Service

•

If there is no sound in the PHONES

STUDIO outputs:

Details concerning Warranty Service are spelled out

in the Warranty section on page 19.

• Make sure the PHONES/STUDIO OUTS

SOURCE button on the front panel is up

(INPUT SOURCES selected).

• Make sure the PHONES or STUDIO

Level control is turned up.

• Make sure the STUDIO OUTS ON/OFF button

is ON.

If you think your Big Knob has a problem, please do

everything you can to conﬁrm it before calling for

service. Doing so might save you from the depriva-

tion of your Big Knob and the associated suffering.

These may sound obvious to you, but here are some

things you can check. Read on.

•

If there is no sound in the MONITOR OUTPUTS

• Make sure the correct MONITOR SELECT

button is pushed in and the trim control for the

MONITOR OUTPUT is set correctly.

Troubleshooting

•

Make sure the cable connecting the MONITOR

No Power

OUTPUT to the active speaker or power ampli-

ﬁer isn’t defective and the ampliﬁer/speaker

combination is working correctly.

•

Our favorite question: Is it plugged in?

Make sure the power cord is securely seated in

the IEC socket and plugged all the way into

the AC outlet.

Bad Sound

•

Is the input connector plugged completely into

the jack?

•

Make sure the AC outlet is live (check with a

tester or lamp).

•

Is it loud and distorted? Make sure the trim

control and level switch for the selected input

is set correctly. Reduce the signal level on the

input source if possible.

Is the POWER switch on? Make sure the

POWER switch on the rear panel is in the ON

position (up).

•

Is the POWER LED on the front panel illumi-

nated? If not, make sure the AC outlet is live. If

so, refer to “No Sound” below.

•

If possible, listen to the signal with headphones

plugged into the input source device. If it sounds

bad there, it’s not Big Knob causing the problem.

Are all the lights out in your building? If so,

contact your local power company to get power

restored.

Make sure the trim control for the MONITOR

OUTPUT is set correctly and not overdriving the

input stage of the active speaker or ampliﬁer to

which it is connected.

If the POWER LED is not illuminated, and you

are certain that the AC outlet is live, it will be

necessary to have Big Knob serviced. There are no

user serviceable parts inside. Refer to “Repair” at

the end of this section to ﬁnd out how to proceed.

Noise/Hum

•

If a turntable is connected to the PHONO

inputs on Big Knob, make sure the ground wire

from the turntable is connected to the GND

terminal on Big Knob.

No Sound

•

Is the POWER LED on the front panel illumi-

•

If a turntable is not connected to the PHONO

inputs, make sure the PHONO INPUT SOURCE

SELECT button is not pushed in. Also make

sure the RCA shorting plugs are connected to

the PHONO inputs when not being used.

nated? If not, refer to “No Power” above.

•

Is the correct INPUT SOURCE SELECT button

selected? Make sure the LED above the INPUT

SOURCE SELECT button is lit.

•

Check the signal cables between the input

sources and Big Knob. Disconnect them one by

one. When the noise goes away, you’ll know

which input source is causing the problem.

•

Is the signal source turned up? Make sure the

signal level from the selected input source is

high enough to light up some of the INPUT

meter LEDs on Big Knob’s front panel.

Sometimes it helps to plug all the audio equip-

ment into the same AC circuit so they share a

common ground.

Make sure the trim control and level switch for

the selected input are set correctly.

E. To obtain service from an Authorized Mackie Service Center:

1. Call Mackie Service at 800/898-3211, 7 AM to 5 PM

address of your nearest Authorized Mackie Service Center

and 2) A return authorization (RA). You must have an RA

number before taking your unit to a service center.

2. Make sure that you have a copy of your sales receipt from

the store where you bought the product. It is necessary to

establish purchase date and thus determine whether or not

your Mackie product is still under warranty. If you can’t ﬁnd

it, the Authorized Service Center may charge you for repairs

even if your Mackie product is still covered by the Three-Year

Limited Warranty.

3. Make sure that the problem can be duplicated. If you bring

your Mackie product to an Authorized Service Center and

they can’t ﬁnd anything wrong with it, you may be charged a

service fee.
