20. NOTE: This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or
more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the
receiver.
• Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for
help.
CAUTION: Changes or modifications to this device not expressly
approved by LOUD Technologies Inc. could void the user's authority to
operate the equipment under FCC rules.
21. This apparatus does not exceed the Class A/Class B (whichever is
applicable) limits for radio noise emissions from digital apparatus as
set out in the radio interference regulations of the Canadian Department
of Communications.
ATTENTION — Le présent appareil numérique n’émet pas de bruits
radioélectriques dépassant las limites applicables aux appareils
numériques de class A/de class B (selon le cas) prescrites dans le
réglement sur le brouillage radioélectrique édicté par les ministere des
communications du Canada.
22. Exposure to extremely high noise levels may cause permanent hearing
loss. Individuals vary considerably in susceptibility to noise-induced
hearing loss, but nearly everyone will lose some hearing if exposed to
sufficiently intense noise for a period of time. The U.S. Government’s
Occupational Safety and Health Administration (OSHA) has specified
the permissible noise level exposures shown in the following chart.
According to OSHA, any exposure in excess of these permissible limits
could result in some hearing loss. To ensure against potentially dangerous exposure to high sound pressure levels, it is recommended that all
persons exposed to equipment capable of producing high sound pressure levels use hearing protectors while the equipment is in operation.
Ear plugs or protectors in the ear canals or over the ears must be worn
when operating the equipment in order to prevent permanent hearing
loss if exposure is in excess of the limits set forth here:

Quick Start
We realize that you must be really keen
to try out your new mixer. Please read the
safety instructions on page 2, read this
page, and then have a look through some
of the features and details in this manual.
Set the levels
It’s not even necessary to hear what you’re doing to
set optimal levels. But if you’d like to: Plug in
headphones and turn up the phones knob just a little.
1. Turn on the mixer's power switch.
2. For one channel, press the solo switch in, and
the rude solo light will turn on.
Setup
3. Play something into that input at real-world
levels.
Use the mixer in a nice clean and dry environment,
free from dryer lint and dust bunnies.
4. Adjust that channel's gain control until the
right main meter stays around the 0 dB LED
(marked "level set").
Zero the controls
5. Disengage the channel's solo switch.
1. Fully turn down all the knobs and faders to
minimum, except for the channel EQ and pan
controls, which should be centered.
2. Make sure all buttons are in the out position.
6. Repeat steps 2 to 5 for the remaining channels.
7. Turn up a channel fader to the "U" mark.
8. Slowly turn up the main mix fader until you
hear the signals in your speakers or
headphones.
Connections
9. If needed, apply some channel EQ wisely.
1. Make sure the AC power switch is off before
making any connections.
2. Push the linecord securely into the IEC
connector on the rear panel, and plug it into a
3-prong AC outlet. The mixer can accept any
AC voltage ranging from 100 VAC to 240 VAC.
3. Plug a balanced microphone into one of the mic
XLR (3-pin) connectors. Or connect any linelevel signal (keyboard, or guitar preamp) to a
line input jack using a TS or TRS 1/4" plug.
4. If your microphone requires phantom power,
press in the 48V phantom power button.
5. You can connect a guitar directly to line inputs
1 or 2 without the need for a DI box. Press a
hi-z switch if you connect a guitar directly.
6. The insert jacks of channels 1 to 4 can be used
to connect an external effects or dynamics
processor into the channel signal chain.
7. Connect the main outputs of the mixer (either
XLR or TRS 1/4") to the line-level inputs of your
amplifier (with speakers already attached) or
to the line-level inputs of powered speakers.
8. Engage the main mix switch in the control
room/phones source selection, so the meters
will show the main mix levels in the next steps.
10. Adjust the channel faders to get the best mix.
Keep the gain controls and faders fully down on
unused channels.
11. During the performance, if you notice a channel
OL LED turning on during peaks, carefully turn
down that channel's gain control until OL does
not turn on.

Loosely based on a dream sequence in which the technical writer is given keys to a
sports car of his choice, unlimited gas, and closed roads. The dream suddenly ends and
reality kicks in. A mixer manual to write, a mixer manual to write!
•
When shutting down, turn off any power
amplifiers or powered speakers first. When
powering up, turn them on last. This will
reduce the chance of turn-on or turn-off
thumps.
•
Always turn down the phones level when
making connections, pressing solo, or doing
anything that may cause loudness in the
headphones. This will help protect your
hearing.
•
Always turn down the main mix level and
control room level when making connections to
the mixer. Better yet, turn off the power.
•
Save the shipping box!
Owner's Manual 3
Introduction
Thank you for choosing a Mackie Onyx 1220i
professional compact mixer. The Onyx-i series of mixers
offer built-in FireWire, along with the newest features
and latest technologies for live sound reinforcement
and analog or digital studio recording, all in a durable,
road-worthy package.
Features
The Onyx 1220i is equipped with four of our premium
precision-engineered studio-grade Onyx mic preamps.
Mackie is renowned for the high-quality mic preamps
used in our mixers, and the Onyx mic pre’s are better
than ever, with specifications rivaling expensive
stand-alone mic preamplifiers.
Channels 1 and 2 feature high-impedance
instrument/line-level inputs so you can connect an
acoustic, electric, or bass guitar directly into the mixer,
eliminating the need for an external direct box.
Extremely adaptable DAW integration
•
Premium 12-channel super-compact analog
mixer with integrated Fire wire I/O
•
4 mono channels (mono mic and mono line
inputs)
•
4 stereo channels (stereo line inputs)
•
4 Onyx mic preamps with sound comparable to
boutique preamps
•
3-band Perkins EQ with sweepable mids on
mono channels
•
3-band Perkins EQ on stereo line channels
•
Flexible FireWire routing with up to 12
channels pre/post EQ, aux sends and master
L/R routable to computer
•
2 channels of FireWire monitoring routable to
either the control room or channels 11 and 12
•
2 independent aux sends with separate pre/post
switches
•
Selectable instrument inputs on first two
channels – no DI box is needed
•
Individual 48v phantom power switches on all
mic inputs
•

Optional rack kit available
Recording and Mixing
Channels, aux sends or the master L/R can be sent
straight to your computer via FireWire for recording.
Pre/post EQ taps on every channel allow you to integrate
our renowned Perkins EQ into the record path. Plus, a
stereo return from your DAW, or iTunes® is assignable to
the control room section or straight back into channels
11-12 for mix integration.
Powerful Effects Engine
With both aux sends routable to your DAW, the 1220i
allows you to use your favorite plug-in as a realtime
effect. Just route an aux send to your DAW, apply the
plug-in and assign your DAW outputs to the control
room or to channels 11-12 for instant integration into
the mix.
Live Recording
Live sound recording could not be simpler with the
1220i. The ability to record individual channels either
wet or dry allows for studio quality multi-track
recordings for later editing and mixdown. Or simply
record the main mix, allowing for immediate creation of
CDs right at the gig.

This diagram shows an acoustic guitar mic'd up directly to channel 1 and a microphone connected to
channel 2 for vocals. A guitar processor is connected to the insert jack of channel 1.
An effects processor receives a mono input from the aux 1 send, and its stereo outputs connect to the
stereo return inputs. Aux 1 is set post-fader, using the Aux 1 pre/post switch in the Aux Master section.
A Mackie SRM150 powered speaker is connected to aux send 2 as a monitor for the performer(s).
Aux 2 is set to pre-fader, using the Aux 2 pre/post switch in the Aux Master section.
Mackie SRM450v2 powered speakers are connected to the left and right main outputs.
A laptop connects to the FireWire port, and allows the 2-channel main mix of the performance to be
recorded using your audio production software. Two channels of audio can also play from the computer
to the main mix. For example, you can play intermission music when the call for an egg-nog decaf latté
or green tea gets too strong and you have to take a break.

Mackie SRM450v2 Powered Speakers
(Stage Monitors) Aux Send 1
This diagram shows an electric guitar connected to the channel 1 line input via an amplifier modeller, a
bass guitar connected directly to channel 2 (hi-z switch in), microphones connected to the channel 3 and
4 mic inputs, a drum machine connected to the channel 5-6 stereo line inputs, and a keyboard connected
to the channel 7-8 stereo line inputs. An iPod dock connects to the tape input.
A dynamics processor is connected to the insert jack of channel 2 to work its magic on your bass.
Vocal compressors are connected to the channel 3 and 4 inserts.
A delay processor receives a mono input from aux 2 send (in post-fader mode), and its stereo outputs
connect to the stereo aux 1 return inputs.
A plethora of SRM450v2 powered speakers are strewn across the stage as monitors for the band; they
are connected to the aux 1 send jack (in pre-fader mode). Headphones are used to monitor levels.
The club is driven by connecting quad HD1801 powered subwoofers and a pair of HD1531 powered
speakers to the main left and right outputs.
A laptop computer connects to a FireWire port, allowing the 2-channel main mix, individual channels,
and the aux sends to be recorded. Two channels can be played back from your audio production
software. These can enter as either a source for the control room and phones, or channels 11 and 12.

This diagram shows an electric guitar connected directly to the channel 1 input (hi-z switch in), a bass
guitar connected directly to channel 2 (hi-z switch in), an acoustic guitar mic'd up and connected to the
channel 3 mic input, a studio mic connected to the channel 4 mic input, an electronic drum set connected
to the channel 5-6 stereo line inputs, a keyboard connected to the channel 7-8 stereo line inputs, and a
keyboard mono output connected to channel 9 (left input). A CD player connects to the tape input.
A multi-FX processor is connected to the insert jack of channel 1 to work its magic on your guitar. A
dynamics processor is connected to the insert jack of channel 2 for your bass. A compressor is connected
to the insert jack of channel 4 for your vocals.
Mackie HR824mk2 powered reference monitors are used for your control room listening. The
engineer's headphones are used to monitor levels. Aux 2 is set up to provide the feed to a headphone
amplifier and your band's headphones.
A desktop computer connects to a FireWire port, allowing the 2-channel main mix, individual channels,
and the aux sends to be recorded, and two channels to be played back using audio production software.
Mixer channels 11-12 can play the 2-channel signals from your computer if the FW 1-2 switch at the
top of the 11-12 channel strip is engaged. Aux 1 and 2 can be sent via FireWire to a software effects
plug-in. (In the case above, aux 2 is used for the headphone amp.)

This diagram shows a voice-over microphone connected to the channel 1 mic input, a video deck's
audio outputs connected to channels 5/6, with its audio inputs receiving the main mix from the
1/4" main outputs. A synthesizer is connected to channel 7/8, and an electronic drum kit is connected
to channel 11/12.
An effects processor and a sampler each receive a mono input from an aux send (post-fader), and
their stereo outputs connect to the respective stereo return inputs. A keyboard controller is attached to the
sampler. Headphones are used to monitor all levels, using a headphone amp with multiple headphones,
including one in the voice-over booth.
A pair of Mackie HR824mkII powered reference monitors are connected to the left and right control
room outputs for careful and accurate monitoring in the control room.
A desktop Mac or PC is connected to a FireWire port, allowing the 2-channel main mix to be recorded
and two channels to be played back. Two cinema screens are connected to the desktop, one displaying
audio and the second for video. A RAID rack is attached to the computer for mass storage. A recorder is
connected to the XLR main outs, and utilized as the master recorder.

1. POWER CONNECTION
3. FIREWIRE CONNECTIONS
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. The Onyx
1220i has a universal power supply that can accept 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.
FireWire is a high-speed two-way interface for
connecting digital devices. Two FireWire connectors
allow the transfer of digital audio to and from your
computer or digital audio workstation (DAW) with
ultra-low latency. Usually, only one connector is used.
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 [46] will glow
with happiness, or at least it will if you have the mixer
plugged into a suitable live AC mains supply.
Press the bottom of this switch to put the mixer into
standby mode. It will not function, but the 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.
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 possibilities of any
turn-on, or turn-off thumps in your speakers.
The FireWire interface provides the following outputs
to your computer:
•
Channels 1–12, tapped pre-fader, and either
pre-EQ, or post EQ (your choice).
•
Aux send 1 and 2 (a copy of the final aux
outputs to your stage monitors or processors).
•
Left/right main mix. The left/right main mix
at the FireWire output is not affected by the
main mix level control (important for recording
live).
Use FireWire to record a live performance directly to
your computer, then you can mixdown to a stereo mix
later. Or you can use FireWire to turn your Onyx mixer
into a high-quality computer audio interface for your
DAW.
FireWire also provides a return for two channels from
a DAW or laptop. This can be routed through the control
room/phones via the FireWire button [36], to
monitor the computer audio through your control room
speakers or headphones (or through the main
speakers if assign to main mix [37] is selected). In
this way, you can listen to pre-recorded songs and
iTunes® as intermission music, or examples of how the
practice sessions should really sound.
These same two channels from the computer can
also be chosen as inputs to channels 11 and 12,
allowing you to adjust the gain, EQ, level, and pan,
Owner's Manual 11
as well as to solo, and add to aux send 1 and 2. This
is routed using the FW/line input selector [23] on
channels 11 and 12. This is useful for live
performances, where those 2 channels might have,
for example, a software synthesizer you are
triggering from a MIDI keyboard, and you want to
treat the softsynth as "just another instrument," with
equal processing and routing options as the hardware
keyboards coming into the other channels.
The FireWire interface works with both PC (using
ASIO for Windows XP and Vista) and Mac (Core Audio
for Mac OS 10.4.11 or higher).
4. LEFT/RIGHT XLR MAIN OUTPUTS
These male XLR connectors provide a balanced linelevel signal that represents the end of the mixer chain,
where your fully mixed stereo signal enters the real
world. Connect these to the inputs of your main power
amplifiers, powered speakers, or serial effects
processor (like a graphic equalizer or compressor/
limiter). It provides a fully balanced signal that is the
same level as the 1/4" TRS main out jacks [13] on the
top panel.
5. MAIN OUTPUT LEVEL
When this switch is out (+4 dB), the XLR main
outputs [4] provide a "+4 dBu" line-level signal. You
can then connect these outputs to the line-level inputs
of power amplifiers, powered loudspeakers, or serial
processors.
When the switch is pushed in (mic), the XLR main
outputs are attenuated to microphone level. You can
then connect these outputs safely to the microphone
inputs of another mixer, providing a submix for
keyboards or drums, for example, in a live sound
application. The main outputs can then be plugged
directly into a stage snake, and appear back at the front
of house console like any other microphone level source.
When mic is engaged, you can safely plug the
XLR main output into a mixer's microphone
input, even if it provides 48 V phantom power.
The switch is recessed, to reduce the chance of
accidently turning it on or off when plugging things in.
6. AUX SEND 1 and 2
These 1/4" TRS connectors allow you to send balanced
or unbalanced line-level outputs to external effects
devices, headphone amplifiers, or stage monitors. These
could either be passive stage monitors powered by an
external amplifier, or powered stage monitors with
built-in power amplifiers.
Aux send 1 and aux send 2 are independent of each
other, so you can set up two separate aux mixes.
The aux 1 send signal is the sum (mix) of all the
channels whose aux 1 send control [29] is set to more
than minimum. The aux 2 send is the sum of all the
channels whose aux 2 send control is set to more than
minimum. The overall aux output level can be adjusted
with the aux send master controls [42].
The aux sends can either be pre or post fader,
depending on the position of the pre/post switches [43].
For stage monitor work, use pre, so the stage monitors
do not increase in volume when the channel faders are
adjusted. Imagine how upsetting that can be to big hairy
drummers. This allows you to set up the monitor mix
and levels just right, and not have it change every time a
channel fader is adjusted.
For external processors, use post. In this way, the feed
to external processors will vary with the channel faders,
so the level of any returned effect (like an echo) will
also change if the channel fader is changed, keeping
them in the same ratio (wet/dry).
7. AUX RETURN 1 and 2
These 1/4" TRS stereo input connectors allow you to
add the stereo processed output from external effects
processors or other devices to the main mix.
Level adjustment of the incoming signals is made with
the aux return controls [44].
The signals going into aux return 2 can also be added
to aux send 1 by engaging the return to aux 1 switch
[45]. For example, you could add effects from an
external effects processor to your stage monitors.
You can also use these inputs to add any stereo linelevel signals to your main mix, so it could be another
line-level source, not just an effects processor.
If you are connecting a mono source, use the left
(mono) aux return input, and the mono signals will
appear on both sides of the main mix.
8. INSERT (Ch. 1-4)
These unbalanced 1/4" jacks on channels 1-4, are for
connecting serial effects processors such as
compressors, equalizers, de-essers, or filters. The insert
point is after the gain control [21] and low cut filter
[19], but before the channel’s EQ and fader [33]. 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. To do this requires a standard insert
cable that must be wired thusly:
Tip = send (output to effects device)
Ring = return (input from effects device)

Insert jacks can be used as channel direct outputs;
post-gain, and pre-EQ. See the connector section on
page 29 (figure G) showing three ways to use inserts.
Connection Section
This is where you plug in things such as: microphones,
line-level instruments, guitars, effects, a recorder, PA
system, powered monitors, powered subwoofer, etc.
Check out the hookup diagrams for some connection
ideas. See Appendix B (page 28) for further details and
some rather lovely drawings of the connectors you can
use with your mixer.
9. MIC INPUTS
This is a female XLR connector, that accepts a
balanced microphone input from almost any type of
microphone. The microphone preamps feature our Onyx
design, with higher fidelity and headroom rivaling any
standalone mic preamp on the market today.
The XLR inputs are wired as follows:
Pin 1 = Shield or ground
Pin 2 = Positive (+ or hot)
Pin 3 = Negative (– or cold)
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
connector.
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.
PHANTOM POWER
Most modern professional condenser mics require
48V phantom power, which lets the mixer send lowcurrent 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.
Phantom power for each channel can be selected
using that channel's phantom [20] switch.
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 are certain it is safe.
10. MONO LINE INPUTS (Ch. 1-4)
These 1/4" jacks share circuitry (but not phantom
power) with the mic preamps, and can be driven by
balanced or unbalanced sources.
To connect balanced lines to these inputs, use a 1⁄4"
Tip-Ring-Sleeve (TRS) plug, wired as follows:
Tip = Positive (+ or hot)
Ring = Negative (– or cold)
Sleeve = Shield or ground
Owner's Manual 13
To connect unbalanced lines to these inputs, use a
1⁄4" mono (TS) phone plug, wired as follows:
Tip = Positive (+ or hot)
Sleeve = Shield or ground
The line-level inputs of channels 1 and 2 can also
accept instrument-level signals if the hi-z switches
[18] are pressed in. This allows you to connect guitars
directly to channels 1 and 2, without the need for a
DI box. The input impedance is optimized for direct
connection, and high-frequency fidelity is assured.
11. STEREO LINE INPUTS (Ch. 5-12)
These 1/4" jacks can be driven by balanced or
unbalanced sources.
To connect balanced lines to these inputs, use a
1⁄4" Tip-Ring-Sleeve (TRS) plug, wired as follows:
Tip = Positive (+ or hot)
Ring = Negative (– or cold)
Sleeve = Shield or ground
To connect unbalanced lines to these inputs, use a
1⁄4" mono (TS) phone plug, wired as follows:
Tip = Positive (+ or hot)
Sleeve = Shield or ground
If you just have a mono source, plug it into the left
input (labeled left/mono), and the signal will appear
(as if by magic) equally on the left and right of the main
mix.
12. CTRL-RM OUT
These 1/4" TRS jacks provide balanced left and rightline-level outputs to run studio monitors in the control
room. Connect these outputs to the inputs of an
amplifier, powered speakers, or recording device.
The source that plays in the control room,
headphones, and meters can be selected using the
switches [35, 36] in the control room/phones source
matrix:
•
The main mix, if main mix is selected as the
control room/phones source
•
Tape outputs, if tape is selected
•

13. LEFT/RIGHT 1/4" MAIN OUTPUTS
These 1/4" TRS output connectors provide the
balanced or unbalanced line-level output of the main
mix to an anxiously-waiting world. This is the same
signal that appears at the XLR main outputs [4] on the
rear panel, except it is not affected by the main output
level switch [5].
Connect these outputs to the next device in the signal
chain, such as an external processor (graphic equalizer
or compressor/limiter), external power amplifiers
running passive loudspeakers, or to the inputs of
powered loudspeakers. They could also be connected to
the inputs of a balanced 2-track recorder, when doing a
"live to 2-track" type recording.
14. ALT 3–4 OUT
These 1/4" TRS jacks provide a balanced line-level
signal that can provide an alternate stereo mix for
recording or subgrouping. Connect these outputs to the
inputs of an amplifier, powered speaker, or recording
device.
Any channel whose mute switch [31] is engaged, is
added to the alt 3-4 outputs.
The alt 3-4 output doesn’t have a master level control.
All channels assigned to the alt 3-4 bus are summed
together (post-fader and pan) and sent directly to the
alt 3-4 out.

15. TAPE INPUTS
17. HEADPHONE OUTPUT
These 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.
This 1/4" TRS connector supplies the output to your
stereo headphones. It is the same signal that is routed
to the control room outputs [12], as determined by the
control room/phones source matrix [35, 36]. The
volume is controlled with the phones knob [39], right
next to the control room knob [38].
Push in the tape button [36] to route the tape input
to the control room and phones outputs [12, 17]. This
allows you to play back recordings of your mixes.
Push in the assign to main mix button [37] to route the
tape input to the main outs [4, 13]. This allows you to play
back music between sets over the main PA speakers.
Pushing tape in the source matrix and
pushing assign to main mix can create a
feedback path between tape in and tape out.
Make sure your tape deck is not in record, record pause,
or input monitor mode when you engage these switches,
or make sure the control room level control is turned all
the way down first.
16. TAPE OUTPUTS
These 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
affected by the main mix level control [51]. The output
could also be used as an extra set of main outputs for
feeding another zone.
Whenever a solo switch [34] is engaged, you will
only hear the soloed channel(s) in the headphones.
This gives you the opportunity to audition the channels
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.)
The phones output follows standard conventions:
Tip = Left channel
Ring = Right channel
Sleeve = Common ground
WARNING: The headphone amp is loud, and
can cause permanent hearing damage. Even
intermediate levels may be painfully loud
with some headphones. BE CAREFUL! Always turn the
phones level control [39] 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.

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’s settings.

18. HI-Z SWITCH (Ch. 1 and 2 only)
19. LOW CUT (Ch.1–4 only)
Engage this switch if you want to connect guitars
directly to the 1/4" line inputs of channels 1 or 2.
The mono channels each have a low-cut switch (often
referred to as a high-pass filter) that cuts bass
frequencies below 75 Hz at a rate of 18 dB per octave.
Without this switch, you need to use a DI box first,
before connecting guitars. If these switches are not
pressed in, guitars will not sound good, particularly the
high frequency response.
Plugging a guitar into a lower-impedance
line-level input can result in the loss of high
frequencies, causing an unnatural and dull
sound. Normally, you must use a direct box
between a guitar and a mixer’s input, which serves to
convert the impedance of the guitar from high to low.
The hi-z inputs on channels 1 and 2 make the need for
a direct box unnecessary. However: The hi-z inputs are
unbalanced (when the switch is in), so if you’re doing a
live show and running a long cord between the
instrument and the mixer (say over 25 or 30 feet), it is
best to use a direct box with a balanced output to avoid
picking up noise over the length of the cord.
The low cut switch affects both the mic and line
inputs.
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,
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.
Owner's Manual 17
20. 48V PHANTOM POWER (Ch.1–4 only)
22. SEND FIREWIRE PRE/POST
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.
Each channel of the mixer can send a FireWire output
to your computer or DAW. The FireWire output from
each channel can be tapped before (pre) or after (post)
the channel EQ. (The output is always pre-fader.)
Press this switch in if your microphone requires
phantom power. (Always check the position of this
switch before connecting microphones.)
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 level [51] 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.
21. GAIN CONTROL
If you haven’t already, please read the level-setting
procedure on page 3.
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.
If the signal originates through the mic XLR jack,
there will be 0 dB of gain with the knob fully down,
ramping to 60 dB of gain fully up.
Through the 1⁄4" line input of channels 1-4, there is
20 dB of attenuation fully down and 40 dB of gain fully
up, with unity gain "U" at 11:00.
Through the 1⁄4" line input of channels 5-12, there is
20 dB of attenuation fully down and 20 dB of gain fully
up, with unity gain "U" at 11:00.
This 20 dB of attenuation can be very handy when
you are inserting a hot signal, when you want to add EQ
gain, or both. Without this “virtual pad,” there is more
chance of channel clipping.
18 Onyx 1220i
If you want the mixer EQ to affect the FireWire
recording, then set this switch to post. This is useful
in recording channels in a studio (where the recording
includes the beneficial effect of our Perkins EQ).
If you would rather record the straight signals from a
live performance, and EQ them later in your DAW, then
set this switch to pre. This is good for live work, where
you may have added EQ to adjust for the room, and yet
not want this added to your recording.
23. INPUT (LINE or FW 1-2)
Channel 11 and 12 can either be fed from the
1/4" line level inputs, or by two outputs from a computer
via FireWire. This switch lets you choose which to use.
Either way, the channels receive line-level analog audio
signals just prior to the gain control, so channel setup,
gain adjustment and EQ adjustment are the same for
line or FireWire. This is useful for virtual instruments
that want to be "just another channel" among hardware
instruments.
CHANNEL EQUALIZATION (EQ)
There are two different flavors of EQ:
Mono Channels 1-4
3-band EQ with shelving high, shelving low, and
peaking mid EQ with adjustable mid frequency.
Stereo Channels 5-12
3-band EQ with shelving high, shelving low, and
peaking mid EQ.
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.
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. 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.
24. HIGH EQ
The high EQ provides up to
15 dB of boost or cut above
12 kHz, and it is also flat (no
0
boost or cut) at the detent. Use
it to add sizzle to cymbals, an
overall sense of transparency,
or an edge to keyboards, vocals, guitar and bacon frying.
Turn it down a little to reduce sibilance or to mask tape
hiss.

The mid EQ provides up to
15 dB of boost or cut, and it is
also flat (no boost or cut) at
the detent. The frequency at
which the cut or boost occurs is
set by the mid EQ frequency
control [25].

Most of the root and lower harmonics that define
a sound are located in the 100 Hz–8 kHz frequency
range, and you can create drastic changes with these
two knobs. Many engineers use mid EQ to cut midrange
frequencies, not boost them. One popular trick is to
set the mid fully up, turn the frequency knob until you
find a point where it sounds just terrible, then back the
mid down into the cut range, causing those terrible
frequencies to disappear. Sounds silly, but it works.
Sometimes.

27. MID EQ LEVEL (Ch. 5-12)
The mid EQ provides up to 15 dB of boost or cut at
2.5 kHz, and is flat at the detent.
28. LOW EQ
The low EQ provides up to
15 dB of boost or cut below
80 Hz. The circuit is flat at the 0
center detent position. This
frequency represents the punch
in bass drums, bass guitar, fat
synth patches, and some really serious male singers who

29. AUX SEND 1 and 2
31. MUTE switch and ALT 3–4
These controls allow you to set up two independent
mixes, typically for running stage monitors or external
effects processors.
The dual-purpose mute/alt 3-4 switch is a Mackie
signature. When Greg was designing our first product,
he had to include a mute switch for each channel. Mute
switches do just what they sound like they do. They turn
off the signal by “routing” it into oblivion. “Gee, what
a waste,” he reasoned. “Why not have the mute button
route the signal somewhere else useful, like a separate
stereo bus?”
The controls are off when turned fully down, deliver
unity gain at the center, and can provide up to 15 dB
of gain turned fully up. Chances are that you will never
need this extra gain, but it’s nice to know it’s there if
you do.
Aux Send 1 and 2 [6] are line-level outputs, and
are used if you want to connect external processors,
powered stage monitors, or external power amps with
passive stage monitors. Aux Return 1 and 2 [7] are linelevel inputs, typically used to return the output from
external processors back to the main mix.
Carefully adjust how much of each channel appears
in your aux mixes. For example, if you are running stage
monitors, and someone wants "more me, and less them,"
adjust these carefully.
The aux sends can either be pre or post fader,
depending on the position of the aux pre/post switches
[43]. For stage monitor work, use pre, so the stage
monitors do not increase in volume when the channel
level is adjusted. For external processors, use post. In
this way, the feed to external processors will vary with
the channel level, keeping them in the same ratio
(wet/dry).
30. PAN
For mono channels 1-4, this control allows you to
adjust how much of the channel signal goes to the left
main mix, and how much goes to the right main mix.
It has no effect on the aux, as these are mono. In the
center position, the mono channel is split equally to the
left and right.
Pan also affects the channel output to the Alt 3–4 mix
if a channel mute switch is engaged.
For channels 5-12, pan acts in a similar way to a home
stereo balance control (panning left turns down the
right channel, and panning right turns down the left
channel).
If you have a stereo source and the mixer's stereo
inputs are already taken, connect the source's left
output into channel 1, and the right into channel 2. Pan
the channel 1 fully left, and channel 2 fully right, then
the source will appear in the main mix in full stereo.
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.
20 Onyx 1220i
So mute/alt 3-4 really serves two functions—muting
(often used during mixdown or live shows), and signal
routing (for multitrack and live work) where it acts as
an extra stereo bus.
To use this as a mute switch, all you have to do is not
use the alt 3-4 outputs [14]. Then, whenever you assign
a channel to these unused outputs, you’ll also be
disconnecting it from the main mix, effectively
muting the channel. The mute switch also disconnects
the channel from the post-fader aux send bus. The
channel’s signal is still present on the pre-fader aux
send bus, so muting a channel does not affect your stage
monitors, and the quiet and gentle disposition of your
lead singer.
To use this as an alt 3-4 switch, all you have to do is
connect the alt 3-4 outputs to whatever destination you
desire. Here are two popular examples:
When doing multitrack recording, you can use the
alt 3-4 outputs as a stereo or dual-mono feed to your
multitrack.
When doing live sound or mixdown, it’s often handy
to control the level of several channels with one knob.
That’s called subgrouping. Simply assign these channels
to the alt 3-4 mix, engage alt 3-4 in the control room/
phones source matrix [36], and the signals will appear
at the control room [12] and phones [17] outputs. If
you want the alt 3-4 signals to go back into the main
mix, engage the assign to main mix switch [37] and the
control room knob [38] will control the levels of all the
channels assigned to alt 3-4.
Another way to do the same thing is to assign the
channels to the alt 3-4 mix, then patch out of the alt
3-4 out (left/3 and right/4) back into an unused stereo
channel (5-12). If that’s your choice, don’t ever engage
the mute/alt 3-4 switch on that stereo channel, or you’ll
have every dog in the neighborhood howling at your
feedback loop.
Another benefit of the alt 3-4 feature is that it can act
as an “afl” (after fader listen). Just engage a channel’s
mute/alt 3-4 switch and the alt 3-4 switch in the source
matrix and you’ll get that channel, all by itself, in the
control room and headphones.

33. CHANNEL FADER
This is the last control in a channel’s signal path, and
it 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 10 dB, should you need to boost a section of
a song. If you find that the overall level is too quiet or
too loud with the level near unity, check that the gain
control [21] is set correctly.
34. SOLO
Whenever a solo switch is engaged, you will only hear
the soloed channel(s) in the headphones and control
room. This gives you the opportunity to audition the
channels before they are added to the main mix or alt
3–4 mix. You can still hear, even when the fader is down.
Solo is also used to set the gain of each channel
correctly. When a channel is soloed, you can adjust the
channel gain [21] until your input source reaches the
level of the 0 dB LED of the right meter.

These LEDs indicate the channel’s signal level after

a signal is present, or if the channel is being overloaded.

Solo signals reaching the headphones and
control room are not affected by the channel
level or main level; therefore, turn down the
phones level [39] and control room level [38] first, as
soloed channels may be loud.
The rude solo light [41] will turn on as a reminder
that what you are listening to in the headphones and
control room is just the soloed channel(s).
For stereo channels, the mono sum of the left and
right is soloed.
Soloed channels are sent to the source mix, which
ultimately feeds your control room, phones, and meters.
Whenever solo is engaged, all source selections (main
mix, alt 3-4, tape, and FireWire) are defeated, to allow
the soloed signal to do just that—solo!

Control Room/Phones and
Meters
Typically, the engineer sends the main mix to an
audience (for a live show) or to a mixdown deck (if
recording). But what if the engineer needs to hear
something other than the main mix in the control room
or headphones? With the Onyx 1220i, the engineer has
several choices of what to listen to. This is one of those
tricky parts, so buckle up.
Tape is the stereo signal coming in from the tape in
[15] RCA jacks. FireWire is a 2-track feed coming in
through the FireWire [3] connection from your
computer. Alt 3-4 is the additional stereo mix bus
formed when any channel is muted with the
mute/alt 3-4 switch [31].
Selections made here deliver stereo signals to the
control room, phones, and meters. With no switches or
main mix [35] engaged, there will be no signal at these
outputs and no meter indication.
The exception is the solo function. Regardless of the
source matrix selection here, engaging a channel’s solo
switch will replace that selection with the solo signal,
sent to the control room, phones, and the right meter.
37. ASSIGN TO MAIN MIX
Let’s say you’re doing a live show: "You're doing a live
show." Intermission is nearing and you want to play a
soothing CD for the crowd to prevent them from
becoming antsy. Simply engage this switch and your
source matrix selection, after going through the control
room level control, will feed into the main mix, just as if
it were another stereo channel.
What if you have a playlist of MP3 files on your
computer you want to play during the break? Engage
this switch and the FireWire switch [36] to play your
MP3s directly from your computer, through the source
matrix, and into the main mix.
Another handy use for this switch is to enable the
alt 3-4 mix to become a submix of the main mix, using
the control room level control.
Side effects to engaging this switch:
35. MAIN MIX
Press this switch in to listen to the main mix in your
control room and headphones, and to check the main
mix levels in the meters. In addition to the main mix,
you can listen to any combination of tape, FW 1-2 and
alt 3-4, depending on which of these switches [36] is
engaged.
If the assign to main mix switch [37] is
engaged, you cannot hear the main mix in the
control room or headphones, or see its level
on the meters. This is to prevent feedback caused by
sending the main mix to the main mix.
36. TAPE, FW 1-2, ALT 3-4
Using these source switches, you can choose to listen
to any combination of tape, FireWire, and alt 3-4 in the
control room and headphones, in addition to the main
mix if its source switch [35] is engaged.
22 Onyx 1220i
1. It will also feed any soloed channels into the
main mix, which may be the last thing you
want.
2. If you have main mix as your source matrix
selection and then engage this switch, the main
mix lines to the source matrix will be
disconnected from the control room and phones
outputs, to prevent feedback.
3. If you have tape as your source matrix
selection, and then engage this switch, it can
create a feedback path between tape in and
tape out. Make sure your tape deck is not in
record, record-pause, or input monitor mode
when you engage these switches, or make sure
the control room knob [38] is turned all the
way down.
38. CONTROL ROOM Knob
This controls the volume at the control room outputs,

When a channel is soloed, the left meter shows no
reading, and the right meter shows the level of that
channel’s signal level, pre-fader. The right meter's 0 dB
LED is labeled "level set" to show where the level should
be when adjusting a channel’s gain [21] in the solo

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).

Owner's Manual 23
Aux Master
This section includes the aux sends and the aux
returns. Aux sends tap signals off the channels, via the
aux knobs [29], mix these signals from each channel
together, then sends them out the aux send jacks [6]
and FireWire outputs 11 and 12. The aux sends can be
pre-fader or post-fader (both are post-EQ, but see
page 38).
Post-fader aux sends can be fed to the inputs of an
external processor like a reverb or digital delay. From
there, the outputs of this external processor are fed
back to the mixer’s aux return jacks [7]. Then these
signals are sent through the aux return level controls
[44], and finally delivered to the main mix.
So, the original unprocessed “dry” signals go from
the channels to the main mix, and the processed “wet”
signals go from the aux returns to the main mix, and
once mixed together, the dry and wet signals combine to
create a glorious sound!
Pre-fader aux sends are typically used to provide
another mix for stage monitors. In this case, the aux
returns aren’t used to return the signal. Instead, they
can be used as additional stereo inputs, or not used at
all.
42. MASTER AUX SEND 1 and 2
These knobs provide overall control over the aux send
levels, just before they are delivered to the aux send
outputs [6]. These knobs go from off to +15 db when
turned all the way up.
The aux sends can either be pre or post fader,
depending on the position of the aux pre/post
switches [43].
This is usually the knob you turn up when the lead
singer glares at you, points at his stage monitor, and
sticks his thumb up in the air. (It would follow that if
the singer stuck his thumb down, you’d turn the knob
down, but that never happens.)
The aux sends are also sent to FireWire output 11 and
12 for recording. The levels to FireWire are affected by
these send controls and the pre/post switch.
For stage monitor work, use pre, so the stage
monitors do not increase in volume when the channel
level is adjusted.
For external processors, use post. In this way, the feed
to external processors will vary with the channel level,
keeping them in the same ratio, so that the “wet” signal
level follows the “dry” signal level.
44. MASTER AUX RETURN 1 and 2
These two controls set the overall level of effects
received from the stereo aux return 1 and 2 inputs [7].
These controls range from off to +10 db of gain when
fully clockwise, to compensate for low-level effects.
Signals passing through these controls go directly to
the main mix bus where they are combined with the
other channels. Alternatively, the aux 2 return can be
routed to aux 1 send instead, using the rtn to aux 1
switch [45] described next.
45. RTN TO AUX 1
This switch routes the signal from aux return 2 to the
aux 1 send mix instead of to the main mix bus.
For example, this allows you to use an external effects
device, like a reverb or delay, exclusively for the
monitors. When this switch is pushed in, the effects
signals coming into the aux return 2 jacks are added to
your aux 1 stage monitor mix. Adjust the effects level
coming in with the aux 2 return controls [44], until it
sounds just right in your monitors.
AUX SEND 1-2 and FIREWIRE
A copy of the aux send 1 and 2 outputs is always
available via FireWire to send to a computer. The
FireWire output is affected by the channel aux send and
master aux send controls. For example, you can set up a
software effects processor as follows:
•
Set up an aux send in post mode.
•
FireWire outputs 11 and 12 are always available
to send aux send 1 and 2 to your computer.
•
Pass this through a software effects processor
or plug-in of your choice.
•
Return the processed output from the effects
processor to mixer channels 11 and 12 (input
switch [23] set to FW 1-2).
•
Alternatively bring the processed sounds into
the control room matrix (engage FW 1-2 [36])
and add it to the main mix (engage assign to
main mix [37]).
•
You can even use the computer as two separate
independent mono in, stereo out processors.
Have aux 1 go into one plug-in, and aux 2 go
into a different one. The stereo outputs of both
plug-ins are combined back into the stereo
stream coming back to the mixer.
43. PRE/POST
The pre/post switches determine whether the aux
send signal is tapped from the channels before the
channel level controls (pre-fader) or after (post-fader).
Having a separate pre/post switch for each aux is a
super-useful feature as it allows the use of one effects
processor and one stage monitor chain, at the same
time.

The talkback feature allows the engineer to
communicate with the talent either through the phones
outputs [17] or the aux 1-2 send outputs [6] using the
built-in talkback microphone. This saves a lot of
shouting over the audience's heads as you set up the
talented one's stage monitors to their peculiarly-picky
satisfaction.

This green LED will turn on 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

This is where the built-in talkback microphone is
located. It is an omni-directional dynamic microphone,
and it will pick up your voice from anywhere in front of
the mixer.

4. Slowly turn this talkback level control up until
you get confirmation from whoever is listening
to headphones or monitors that they can hear
and obey your every command.
Once you have set the level, you can leave it there for
the duration of the session or gig.

2. Select the destination, either headphones
and/or aux 1-2, and make sure their levels are
already set nicely, such as phones [39] or aux
sends [42].
MAIN MIX
Push in the phones switch to route the talkback signal
to the headphones. Use this to communicate with the
talent in the studio through the headphones during a
recording session. When the talkback circuit is
activated by pushing the talkback [50] switch, the
control room outputs [12] are attenuated to allow your
voice to come through clearly.
Owner's Manual 25
The aux 1-2 switch routes the talkback signal to the
aux send 1 and 2 outputs [6]. Use this to communicate
with the musicians through their stage monitors when
you are setting up a live performance.
It is fine to have both destination switches pushed in
at the same time, so the talkback signal will be routed
to both destinations. But if you don’t have either of the
destination switches pushed in, the talkback signal
won’t go anywhere. You might as well be talking to a
brick wall.
50. TALKBACK Switch
This is a momentary switch, and as long as you hold
it down, talkback is activated. You can talk into the
built-in microphone and be heard in the headphones
and/or stage monitors.
Release the switch so you can talk about the band
without them hearing you.
Main Mix
51. MAIN MIX
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 [4, 13], and the tape outputs [16].
This gives you the ultimate feeling of power and
control over the sound levels sent to your audience. If
you press the main mix switch [35], you can see the
main mix levels in the meters [40]. Adjust this control
carefully, with your good eye on the meters to check
against overloading, and your good ear to the levels to
make sure your audience (if any) is happy.
This fader does not affect the aux send outputs [6],
alt 3-4 outputs [14], or the main mix FireWire outputs
11-12. It affects the control room or headphones if the
main mix switch [35] is engaged.
The main mix signals are off with the fader fully down,
the “U” marking is unity gain, and fully up provides
10 dB of additional gain. This additional gain will
typically never be needed, but once again, it’s nice to
know that it’s there. The fader is stereo, as it affects
both the left and right of the main mix equally. This is
the ideal control to slowly bring down at the end of a
song (or quickly in the middle of a song if the need ever
arises).
26 Onyx 1220i
MAIN MIX and FIREWIRE
The left and right main mix are permanently assigned
to FireWire outputs 11 and 12. For example, you can
record the live performance main mix onto your
computer. This does not affect the analog main mix
outputs.
The output level to your computer is not affected by
the main mix fader [51].
Congratulations! You’ve just read about all the
features of your mixer. Time for a frosty beverage.
Appendix A: Service
Information
If you think your mixer has a problem, please check
out the following troubleshooting tips and do your best
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.
Troubleshooting
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?
•
Is the channel pan set in the middle?
•
Are the hi-z instrument switches set OK for any
guitars connected to channels 1 or 2?
•
Try unplugging any insert devices from the
insert jacks on channels 1-4.
•
Try the same source signal in another channel,
set up exactly like the suspect channel.
•
Is phantom power required for your
microphone?
Power
•
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.
Repair
For warranty service, refer to the warranty
information on page 40.
Non-warranty service for Mackie products is
available at a factory-authorized service center. To
locate your nearest service center, visit
www.mackie.com, click “Support” and select “Locate
a Service Center.” Service for Mackie products living
outside the United States can be obtained through local
dealers or distributors.
If you do not have access to our website, you can
call our Tech Support department at 1-800-898-3211,
Monday-Friday, normal business hours, Pacific Time, to
explain the problem. Tech Support will tell you where
the nearest factory-authorized service center is located
in your area.
Bad Output
•
Is the main level turned up?
•
Are the EQs set to reasonable levels?
•
Are any aux returns maxed out?
•
Unplug anything from the other line-level
outputs, such as alt 3-4, control room 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.
Noise
•
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.
Owner's Manual 27
Appendix B: Connections
“XLR” Connectors
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.
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.

1⁄4"
TS Phone Plugs and Jacks
“TS” stands for Tip-Sleeve, the two connections
available on a “mono” 1⁄4" phone jack or plug.
See Figure C.
TS jacks and plugs are used in many different
applications, always unbalanced. The tip is connected to
the audio signal and the sleeve to ground (earth). Some

•
Stereo Headphones, and rarely, stereo
microphones and stereo line connections.
When wired for stereo, a 1⁄4" TRS jack or plug is
connected tip to left, ring to right and sleeve to
ground (earth). Mackie mixers do not directly
accept 1-plug-type stereo microphones. They
must be separated into a left cord and a right
cord, which are plugged into two mic preamps.
28 Onyx 1220i
RCA Plugs and Jacks
RCA-type plugs (also known as phono plugs) and
jacks are often used in home stereo and video
equipment and in many other applications (Figure D).
They are unbalanced and electrically identical to a
1⁄4" TS phone plug or jack. See Figure C. Connect the
signal to the center post and the ground (earth) or
shield to the surrounding “basket.”

TRS Send/Receive Insert Jacks
Mackie’s single-jack inserts are the three-conductor,
TRS 1⁄4" phone type. They are unbalanced, but have
both the mixer output (send) and the mixer input
(return) signals in one connector. See 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.

Appendix D: Rack Ear installation instructions
The optional Rack Ear Kit allows the Onyx 1220i
mixer to be mounted in a standard 19” rack. It will be
out of harm’s way and the band may continue tearin’ it
up without fearing any consequences. The mixer takes
up ten rack spaces. Be sure to allow for an extra space
or two above to make connections. The kit contains two
rack ear brackets and six black screws (M3.5 x 8mm).
Tools Required:
One phillips screwdriver, a comfy chair, a bowl of cereal
with milk and bananas (or strawberries, your choice),
toast, and a glass of orange juice (optional).
Procedure:
1. Turn off the mixer and disconnect all cords.
2. Place the mixer face up on a soft and dry flat
surface.
3. Remove the six silver screws as shown below,
place them in the shoe box housing all of those
old baseball cards, and keep them in a safe
place for further use.
4. Using only the new screws supplied, secure
the rack ear brackets to each side of the mixer
as shown. Hand-tighten the screws securely.
The brackets are NOT identical. The right side
bracket has an ‘R’ on the inside of the bracket
flange (see drawing below).
5. Offer up the mixer to the rack and secure it
in place with four rack screws (not supplied).
Remember to leave enough room at the top to
attach the AC power cord and any other connections needed.
6. Relax, you did it! Break out the cereal, frosty
glass of orange juice, the buttered-just-right
toast, and plant your bottom on that comfy
chair of yours and enjoy the sweet taste of
success!

Appendix E: FireWire
The mixer comes with a CD containing the PC driver
software needed to use your mixer's internal FireWire
interface with Windows XP or Windows Vista.
3. The Windows application will start its "Found
New Hardware" wizard. Select "Locate and
install driver software."
Mac OS X contains built-in drivers, so no software
installation is required.
Before installing the drivers from the CD,
please check our website in case there are any
updated drivers available. These will come with
their own installation instructions which will
supercede those shown here.
The CD that contains the PC driver software
is the same CD that this owner's manual PDF
is on. So if you have not browsed the CD and
looked at this owner's manual, you will not be
reading this yet. Its a bit of a paradox really,
because didn't you just read it? Like this bit of
text right now? Hmm..

(if you haven't already).
6. Select “Install the software automatically.”
Owner's Manual 35
7. Select the “Next” command and the driver
software will begin installing.
8. When Windows presents you with a warning
about the software not having passed Windows
testing, select “Continue Anyway.”
10. The following message confirms that the new
software has been installed successfully and
that the found new hardware wizard is
complete.
11. Pack yourself a big lunch and go for a nice walk
outside. Have a picnic and lie back and dream.
Things are going to be so good now.
The audio interface is now ready to use with the
Digital Audio Workstation software of your dreams,
as well as with consumer audio applications such as
iTunes® or Windows Media Player.
A Note on Available Buffer Sizes
In general, you should always experiment with the
available buffer sizes, to find the lowest buffer size that
the machine and recording project can comfortably
work with.
9. Repeat steps 3-8 to allow a second driver to
be installed. The found new hardware box will
appear all over again, so follow these steps and
you are almost done.

USING THE ONYX 1220i WITH A MAC
The Onyx 1220i works with Mac OS 10.4.11 and higher.
This OS includes the Apple FireWire 2.0 driver. The
Onyx 1220i will only work with the 2.0 driver, so if you
have an OS before 10.4.11, you will need to check your
system for updates from the nice folks at Apple.
5. Here you can see the settings for the mixer.
You can also choose it as your default input or
output, as well as designate it to be used for
system sound output. There are 12 channels of
audio input from the Onyx 1220i, and
2 channels of audio output to the Onyx 1220i.
1. Connect a FireWire cable from your Onyx 1220i
to a FireWire port on your Mac.
2. Turn on your Onyx 1220i.
3. Go to the applications folder, open the utilities
folder, and double-click “Audio MIDI Setup.”
4. Click the Audio Devices tab, and select
Onyx i in the “Properties For” drop-down box.
6. The Sample Rate is also shown from 44.1 kHz,
48 kHz, 88.2 kHz and 96 kHz.
7. You’re ready to go with any Mac OS X Core
Audio host application (i.e., Tracktion, Logic,
Cubase, Nuendo, Live, Digital Performer, etc.).
8. In your audio software applications, select and
activate the inputs from the mixer and outputs
to the mixer.

Appendix F: Modifications
The following modifications can be carried out on the
Onyx 1220i by an authorized service center. Authorized
service centers may be found online at:
www.mackie.com/scripts/service_centers/search.asp
Please contact our technical support department if you
are having trouble finding an authorized service center
in your area.
The block diagram on page 32 shows these
modifications as dotted lines in the channel signal flow.
Modifications: Post-Insert FireWire Sends
The pre-EQ channel FireWire sends are pre-insert,
but the circuit board can be modified so that they are
post-insert instead.
For example, this allows for the use of an external
processor on the mic signal, sending the result to the
FireWire, while still being pre-EQ.
Modifications: Post-Fader FireWire Sends
The post-EQ channel FireWire sends are pre-fader,
but the circuit board can be modified so that they are
post-fader instead.
This allows the channel level to control the level of
the FireWire sends.
Modification: Pre-EQ Aux Sends
The pre-fader aux sends are post-EQ, so they are
affected by the channel EQ controls. The circuit board
can be modified so the pre-fader aux sends are pre-EQ
instead of post-EQ.
For example, your stage monitors will not be affected
by any channel EQ adjustments.
