Introduction

Thank you for choosing a Mackie Onyx 1620 profes­sional compact mixing console. The Onyx Series of mix­ers are designed for the digital era and offer the newest features and latest technologies for live sound reinforce­ment and analog or digital studio recording in a durable, road-worthy package.
ONYX 1620
The Onyx 1620 is equipped with eight of our new 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 pres are better than ever, with specifi cations rivaling expensive stand-alone mic preamplifi ers.
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.
Each of the eight mono channels has individual phantom power switches, low-cut fi lters, pre-EQ chan­nel inserts, and an all new four-band EQ design with sweepable mids and EQ bypass switch.
Channels 9 through 16 are four stereo pairs of line inputs, featuring a three-band EQ and EQ bypass switch for each stereo pair.
All mono channels and stereo pairs have four Aux sends, Pan, Mute/Alt 3-4, Solo, 60 mm Fader, and four signal level indicators.
A built-in Talkback mic with routing switches allows you to communicate through the Aux Sends 1-2 or the Phones output.
HOW TO USE THIS MANUAL
We know that many of you can’t wait to get your new mixer hooked up, and you’re probably not going to read the manual fi rst (sigh!). So the fi rst section after the table of contents is a Quick-Start Guide to help you get the mixer set up fast so you can start using it right away. Right after that are the ever popular hook-up diagrams that show typical mixer setups for live sound, recording and mixdown.
Then, when you have time, read the Features Descrip­tion section. This describes every knob, button, and connection point on the Onyx 1620, roughly following the signal fl ow through the mixer from top to bottom and left to right.
Throughout this section you’ll fi nd illustrations with each feature numbered. If you want to know more about a feature, simply locate it on the appropriate illustra­tion, notice the number attached to it, and fi nd that number in the nearby paragraphs.
This icon marks information that is critically important or unique to the Onyx 1620. For your own good, read them and remember them. They will be on the fi nal test.
This icon leads you to in-depth explanations of features and practi­cal tips. While not mandatory, they usually have some valuable nugget of information.
All sixteen channels have balanced direct outputs on two DB-25 connectors for multitrack recording. An optional FireWire card provides all sixteen direct outputs and the L-R Main Mix on a FireWire interface for streaming digital audio to a laptop for multitrack recording in a live situation, or connecting to a DAW in a home studio.

THE GLOSSARY: A Haven of Non-Techiness for the Neophyte
The “Glossary of Terms” is a fairly comprehensive dictionary of pro-audio terms. If terms like “clipping,” “noise fl oor,” or “unbalanced” leave you blank, refer to this glossary for a quick explanation.
ARCANE MYSTERIES ILLUMINATED
“Arcane Mysteries” discusses some of the down ‘n’ dirty practical realities of microphones, fi xed installa­tions, grounding, and balanced versus unbalanced lines. It’s a goldmine for the neophyte, and even the seasoned pro might learn a thing or two.

Getting Started

READ THIS PAGE!!
Even if youre one of those people who never read manuals, all we ask is that you read this page now before you begin using the Onyx 1620. Youll be glad you did!

Zero the Controls

1. Turn down the channel GAIN, AUX, and Fader con­trols, and center the channel EQ and PAN controls.
Owner’s Manual
a line input such as a CD player or tape recorder output. Be sure that the volume of the input source is the same as it would be during normal use. If it isnt, you might have to readjust these levels during the middle of the set.
3. Adjust the channel’s GAIN control so that the LEDs on the RIGHT meter stay around 0 and never go higher than +7.
4. If you’d like to apply some EQ, do so now and return to step 3. Remember to push in the EQ IN/OUT but­ton or the EQ controls wont do anything.
5. Disengage that channel’s SOLO switch.
6. Repeat for each channel.
2. Set all push button switches to their out positions.
3. In the output section (right hand side), turn all the rotary knobs down, the switches out, and the MAIN MIX fader down.
4. Turn the POWER switch off.

Connections

If you already know how you want to connect the Onyx 1620, go ahead and connect the inputs and outputs the way you want them. If you just want to get sound through the mixer, follow these steps:
1.
Plug a microphone or other signal source into channel 1s MIC or LINE input.
2. Plug in the detachable linecord, connect it to an AC
outlet, and turn on the Onyx 1620s POWER switch.
3. Connect cords from the Onyx 1620’s MAIN OUTS
(XLR connectors on the rear panel and 1/4" TRS connectors on the front panel) to your amplifi er.
4. Hook up speakers to the amp and turn it on. If the
amplifi er has level controls, set them however the manufacturer recommends (usually all the way up).

Instant Mixing

1. Leave the microphone plugged into channel 1 and connect a keyboard, guitar or other instrument to channel 2. Be sure to Set the Levels for channel 2 as described above.
2. To get sound out of the speakers, turn up channel 1 and 2 faders to the U mark and slowly turn up the MAIN MIX fader to a comfortable listening level.
3. Sing and play. Youre a star! Adjust the faders for channels 1 and 2 to bring your voice and your instrument up and down to create your own mix.
Other Nuggets of Wisdom
For optimum sonic performance, the channel and MAIN MIX faders should be set near the U (unity gain) markings.
Always turn the MAIN MIX fader and CONTROL ROOM knob down before making connections to and from your Onyx 1620.
When you shut down your equipment, turn off the amplifi ers fi rst. When powering up, turn on the amplifi ers last.

Set the Levels

To set the channel GAIN controls, it’s not even neces- sary to hear what youre doing at the outputs of the mixer. If you want to listen while you work, plug head­phones into the PHONES jack on the front panel, then set the PHONES knob about one-quarter of the way up.
The following steps must be performed one channel at a time.
1. Push in the channel’s SOLO switch. Make sure the
SOLO MODE switch is up (PFL).
2. Play something into the selected input. This could
be an instrument, a singing or speaking voice, or
Never listen to loud music for prolonged periods. Please see the Safety Instructions on page 2 for information on hearing protection.
Save the shipping box! You may need it someday, and you dont want to have to pay for another one.
That’s it for the “Getting Started” section. Next comes the Hookup section that shows you some typical ways that you might use the Onyx 1620 in real applications. After that, you can take the grand tour of the mixer, with descriptions of every knob, button, input, and output. We encourage you to take the time to read all of the feature descriptions, but at least you know its there if you have any questions.

Channel Strips

There are two kinds of channel strips on the Onyx 1620: Mono and Stereo. The mono channel strips (channels 1-8) have mic and line input connectors. In addition,
ONYX 1620
channels 1 and 2 have high-impedance instrument inputs so you can connect a guitar directly to the mixer.
The stereo channel strips (channels 9-16), have two line input connectors per channel strip, left and
right. The stereo path is maintained

1. MIC Input (Channels 1-8)

MIC HI-Z
This is a female XLR connector, which accepts a balanced microphone input from almost any type of microphone. The microphone preamps feature our new Onyx design, with higher fi delity 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)

2. HI-Z Instrument Input (Channels 1-2)

This is a 1/4" connector, which ac­cepts an unbalanced instrument-level input signal from a high-impedance instrument like a guitar.

3. LINE Input (Channels 3-16)

This is a 1/4" TRS connector, which ac­cepts a balanced or unbalanced line-level input signal from almost any source.
When connecting a balanced signal to the LINE inputs, wire them as follows: Tip = Positive (+ or hot) Ring = Negative (– or cold) Sleeve = Shield or ground
When connecting an unbalanced signal, wire them as follows: Tip = Positive (+ or hot)
Sleeve = Shield or ground
Note: For the stereo channels 9-16, if a signal is plugged into the LEFT (MONO) side and nothing is plugged into the RIGHT side, the signal is automatically connected to both LEFT and RIGHT sides. This is called jack normalling. As soon as something is plugged into the RIGHT side, the normalled connection is broken and the LEFT and RIGHT inputs become stereo inputs (LEFT goes to the LEFT MAIN OUT and RIGHT goes to the RIGHT MAIN OUT).

4. MIC/HI-Z Switch

Channels 1 and 2 have an extra button for switching between the MIC and HI-Z inputs. When the button is out (MIC), the XLR MIC input is used and the HI-Z input is disconnected. When the button is pushed in (HI-Z), the 1/4" HI-Z input is used and the XLR MIC in­put is disconnected. The input stage of the HI-Z inputs is specially designed for the high-impedance pickups on guitars.
Plugging a guitar into a lower-impedance line input (like those on channels 3-16)
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
mixers 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, so if youre 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.

5. Low-Cut Switch (Channels 1-8)

The Low-Cut switch, often referred to as a high-pass lter, cuts bass frequencies below 75 Hz at a rate of 18 dB per octave.

Low Cut
you want to hear, and fi ltering it out makes the low stuff you do want much more crisp and tasty. Not only that, but the Low-Cut fi lter can help reduce the possibility of feedback in live situations and it helps to conserve the amplifi er power.
We recommend that you use the Low-Cut fi lter on every microphone application except kick drum, bass guitar, bassy synth patches, or record­ings of earthquakes.

is in combination with the LOW EQ on vocals during live performances.
Many times, bass shelving EQ can really ben­efi t voices. Trouble is, adding LOW EQ also boosts stage rumble, mic handling
clunks, and breath pops. Low Cut removes all those prob­lems so you can add LOW EQ without losing a woofer.

Low Cut with Low EQ Boosted
Here’s what the combination of LOW EQ and Low Cut looks like in terms of frequency curves.

6. 48V Phantom Power Switch (Channels 1-8)

Most professional condenser microphones require phantom power, which is a low-current DC voltage delivered to the microphone on pins 2 and 3 of the XLR microphone connector. Push in the 48V button if your microphone needs phantom power. An LED lights just above the button to indicate that phantom power is ac­tive on that channel.
Dynamic microphones, like Shures SM57 and SM58, do not require phantom power. However, phantom power will not harm most dynamic microphones should you accidentally plug one in while the phantom power is turned on. Be careful with older ribbon microphones. Check the manual for your microphone to fi nd out for sure whether or not phantom power can damage it.
Note: Be sure the MAIN MIX fader (38) is turned down when connecting microphones to the MIC Inputs, especially when phantom power is turned on, to prevent pops from getting through to the speakers.

7. GAIN Control

If you havent already, please read Set the Levels on page 5.
The GAIN control adjusts the input sensitivity of the mic and line inputs. This allows the signal from the outside world to be adjusted to optimal internal operating levels.
If the signal is plugged into the XLR jack, there is 0 dB of gain (unity gain) with the knob turned all the way down, ramping up to 60 dB of gain fully up.
When connected to the 1/4" jack, there is 20 dB of attenuation all the way down, and 40 dB of gain fully up, with a U (unity gain) mark at about 10:00. (On the stereo channels, the GAIN range is –20 dB to +20 dB with unity in the center.)

8. EQ IN/OUT Switch

LINE IN 9-10
This is a true hardware bypass of the Perkins EQ circuitry to insure that there is no coloration of the signal if the EQ is not needed. When
GAIN
U
+20dB-20dB

14. AUX Sends

These tap a portion of each channels signal out to either an effects processor or for stage monitoring. The AUX Send levels are controlled by the channels AUX 1-4 knobs, and by the AUX MASTER 1-4 knobs.
Since the AUX Sends are mono, the left and right sig­nals in the stereo channels are summed together prior to the channels AUX 1-4 controls, sending the combined signal to the AUX SEND outputs.
These are more than just effects and monitor sends. They can be used to generate separate mixes for record­ing, for another zone, or mix-minuses for broadcast.

15. PAN

PAN adjusts the amount of channel signal sent to the left versus the right outputs. On the stereo channels (channels 9-16), the PAN knob works like the balance control on your home stereo (panning left turns down the right channel, and panning right turns down the left channel).
With the PAN knob hard left, the signal feeds either the MAIN LEFT (bus 1) or ALT LEFT (bus 3), depend­ing on the setting of the ALT 3/4 switch. With the knob hard right, the signal feeds either the MAIN RIGHT (bus 2) or ALT RIGHT (bus 4).

This control gives you up to 15 dB of boost or cut at 80 Hz. The circuit is fl at (no boost or cut) at the center detent position. This frequency represents
H
the punch in bass drums, bass guitar, fat synth
patches, and some really serious male singers.
Constant Loudness: The Onyx 1620s 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.

16. MUTE/ALT 3-4

The dual-purpose MUTE/ALT 3-4 switch is a Mackie signature. When Greg was designing our fi rst 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,” Greg reasoned. “Why not have the mute button route the signal somewhere else useful, like a separate stereo bus?” So MUTE/ALT 3-4 really serves
two functionsmuting (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 (41). Then, whenever you assign a channel to these unused outputs, youll also be disconnecting it from the MAIN MIX, effectively mut­ing the channel. The MUTE switch also disconnects the channel from the POST AUX SEND bus. The channel’s signal is still present on the PRE AUX SEND bus.
Page 13
To use this as an ALT 3-4 switch, all you have to do is connect the ALT 3-4 outputs (41) to whatever destina­tion you desire. 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, its 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 (20), and the signals will appear at the CONTROL ROOM (40) and PHONES (24) outputs. If you want the ALT 3-4 signals to go back into the MAIN MIX, engage the ASSIGN TO MAIN MIX switch (21) and the CONTROL ROOM knob (22) con­trols 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 (9-10, 11-12, 13-14, or 15-16). If thats your choice, dont ever engage the MUTE/ALT 3-4 switch on that stereo channel, or youll have every dog in the neighborhood howling at your feedback loop.
Another benefi t 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 (20) and you’ll get that channel, all by itself, in the CONTROL ROOM (40) and PHONES (24).
MUTE/ALT 3-4 is one of those features that can bewilder newcomers, so take your time and play around with it. Once youve got it down, youll probably think of a hundred uses for it!

17. Channel Fader

The fader controls the channels levelfrom off to unity gain at the U marking, on up to 10 dB of addi­tional gain.
“U” Like Unity Gain
Mackie mixers have a U symbol on almost every level control. This U stands for unity gain, meaning no
change in signal level. Once you have adjusted the input signal to line-level, you can set every control at U and your signals will travel through the mixer at optimal levels. Whats more, all the labels on our level controls are measured in decibels (dB), so youll know what youre doing level-wise if you choose to change a controls settings.

18. Signal Level LEDs

These LEDs indicate the channels signal level after the GAIN and EQ controls, but just prior to the channels fader. So even if the fader is turned down, you can see if a signal is present.
If youve followed the Set the Levels procedure, the –20 and 0 LEDs should light frequently, the +10 LED should light occasionally, and the OL (Over­load) LED should not light at all. If the OL LED is blinking frequently, the signal is probably distorted from over­driving the input. Either turn down the GAIN control or turn down the signal at its source.

19. SOLO Switch

This handy switch allows you to hear signals through your headphones or control room outputs without having to route them to the MAIN or ALT 3-4 mixes. Folks use solo in live work to preview channels before they are let into the mix, or just to check out what a particular channel is up to anytime during a session. You can solo as many channels at a time as you like.
Your Onyx 1620 has Dual-Mode Solo. A switch in the master section, SOLO MODE (25) determines which mode youll be hearing. With the switch up, youll get PFL (Pre-Fader Listen), which is after the GAIN and EQ controls, but before the channel fader. With the switch down, youre in AFL” (After-Fader Listen), which is post-fader and post-PAN, making it ideal for mixdown soloing.
Soloed channels are sent to the SOURCE mix, which ultimately feeds your CONTROL ROOM, PHONES, and Meters. Whenever SOLO is engaged, all SOURCE (20) selections (MAIN MIX, ALT 3-4, TAPE, and FIREWIRE) are defeated, to allow the soloed signal to do just thatsolo!

Control Room Matrix, Metering, and Phones

Typically, the engineer sends the MAIN MIX to an audi­ence (if live) 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 1620, the engineer has several choices of what
ONYX 1620
to listen to. This is one of those tricky parts, so buckle up.

20. CONTROL ROOM/PHONES SOURCE

Using the SOURCE switches, you can choose to listen to any combination of MAIN MIX, ALT 3-4, TAPE, and FIREWIRE (optional). By now, you probably know what the MAIN MIX is. ALT 3-4 is that additional stereo mix bus. TAPE is the stereo signal coming in from the TAPE IN RCA jacks. FIREWIRE is a 2-track feed coming in through the optional FireWire card from your computer.
Selections made in the SOURCE matrix deliver stereo signals to the CONTROL ROOM, PHONES, and Meters. With no switches engaged, there will be no signal at these outputs and no meter indication.
The exception to that is the SOLO function. Regard­less of the SOURCE matrix selection, engaging a channels SOLO switch will replace that selec­tion with the SOLO signal, also sent to the CONTROL
LEVEL
ROOM, PHONES,
SET
and Meters.

I have the CD player plugged into the TAPE inputs, and that never gets to the MAIN OUTPUTS! Oh, but it does. 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 fi les on your laptop you want to play during the break? Get the optional FireWire card and engage the FIREWIRE button 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: 1) Engaging this switch also feeds 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 ASSIGN TO MAIN MIX, the MAIN MIX lines to the SOURCE matrix will be discon­nected from the CONTROL ROOM and PHONES outputs, to prevent feedback. Then again, why on earth would anyone want to assign the MAIN MIX to the MAIN MIX?
WARNING: Pushing in both the TAPE button (in the SOURCE matrix) and ASSIGN TO MAIN MIX (21) 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 (22) is turned all the way down (off).

22. CONTROL ROOM Knob

This controls the volume at the CONTROL ROOM outputs, from off () to maximum gain (MAX). It also controls the level of the control room signal going to the MAIN OUTS when ASSIGN TO MAIN MIX is selected in the CONTROL ROOM/PHONES SOURCE matrix.

23. PHONES Knob

This controls the volume at the PHONES output, from off () to maximum gain (MAX).

24. PHONES

This is where you plug in your stereo headphones. It is a 1/4" TRS stereo jack and provides the same signal that is routed to the CONTROL ROOM outputs (40), as determined by the CONTROL ROOM/PHONES SOURCE matrix (20). The volume is controlled with the PHONES knob (23) (right next to the CONTROL ROOM knob).
Page 15
WARNING: The headphone amp is designed to drive any standard head­phones to a very loud level. Were not kidding! It can cause permanent
hearing damage. Even intermediate levels may be painfully loud with some headphones. BE CAREFUL! Always start with the PHONES level turned all the way down before connecting headphones to the PHONES jack. Keep it down until youve put on the headphones. Then turn it up slowly. Why? Always remember: Engineers who fry their ears, fi nd them-
selves with short careers.”

25. SOLO MODE

signal level, a source must be selected in the CONTROL ROOM/PHONES SOURCE matrix, which feeds the CON­TROL ROOM (40) and PHONES (24) outputs. The meters refl ect the program level of the selected source prior to the CONTROL ROOM and PHONES (22/23) level knobs.
The reason for this is because you want the meters to refl ect what the engineer is listening to, and as weve covered, the engineer is listening either to the CON­TROL ROOM outputs or the PHONES outputs. The only difference is that while the listening levels are con­trolled by the CONTROL ROOM and PHONES knobs, the meters indicated the SOURCE mix before those knobs, giving you the real facts at all times, even if youre not listening at all.
Owner’s Manual
Engaging a channels SOLO switch will cause this dramatic turn of events: Any existing SOURCE matrix selections are replaced by the SOLO signal, appearing at the CONTROL ROOM OUTPUTS, PHONES and at the RIGHT METER (LEFT and RIGHT METERS when in AFL SOLO MODE). The audible SOLO levels are then controlled by the CONTROL ROOM knob (22). The SOLO levels appearing on the meters are not controlled by the CONTROL ROOM knobyou wouldn’t want that. You want to see the actual channel level on the meters regardless of how loud youre listening.
With the SOLO MODE switch in the up position, you’re in PFL mode, meaning Pre-Fader Listen (post-EQ). This mode is required for the Set the Levels procedure and is handy for quick spot-checks of channels, especially ones that have their faders turned down.
With the switch down, youre in AFL mode, meaning After-Fader Listen. Youll hear the output of the soloed channel—it will follow the channel’s GAIN, EQ, FADER and PAN settings. Its similar to muting all the other channels, but without the hassle. Use AFL mode during mixdown.
In either mode, SOLO will not be affected by a channel’s MUTE/ALT switch position.

26. LEFT/RIGHT Level Meters

The Onyx 1620s peak meters are made up of two columns of twelve LEDs, with three colors to indicate different ranges of signal level, traffi c light style. They range from –30 at the bottom, to 0 in the middle, to +20 (CLIP) at the top.
The 0 LED in the middle is labeled LEVEL SET to show where the level should be when adjusting a channel’s gain in the solo mode, as described in “Set the Levels on page 5.
If nothing is selected in the CONTROL ROOM/ PHONES SOURCE matrix (20) and no channels are in SOLO, the meters wont do anything. To display a
When a channel is soloed, the meters change to refl ect the level of that channels signal level, pre- or post-fader, depending on the SOLO MODE (25) setting.
You may already be an expert at the world of +4 (+4 dBu=1.23 V) and “–10 (–10 dBV=0.32 V) operating levels. What makes a mixer one or the other is the relative 0 dB VU (or
0 VU) chosen for the meters. A +4 mixer, with +4 dBu pouring out the back will actually read 0 VU on its meters. A “–10 mixer, with a –10 dBV signal trickling out will read, you guessed it, 0 VU on its meters. So when is 0 VU actually 0 dBu? Right now!
Mackie mixers show things as they really are. When 0 dBu (0.775 V) is at the outputs, it shows as 0 dB VU on the meters. What could be easier? By the way, the most wonderful thing about standards is that there are so many to choose from.
Thanks to the Onyx 1620s wide dynamic range, you can get a good mix with peaks fl ashing anywhere between –20 and +10 dB on the meters. Most amplifi ers clip at about +10 dBu, and some recorders arent so forgiving either. For best real-world results, try to keep your peaks between 0 and +7.
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).

27. RUDE SOLO Light

This large green LED fl ashes on and off when a channel’s solo is active, as an additional reminder beyond the indicating LEDs next to each SOLO button. If you work on a mixer that has a solo function with no indicator lights and you happen to forget youre in solo mode, you can easily be tricked into thinking that some­thing is wrong with your mixer. Hence, the RUDE SOLO light. Its especially handy at about 3 am when no sound is coming out of your monitors but your multitrack is playing back like mad.

Auxiliary Section

This section includes the AUX MASTERS (Sends) and the AUX RETURNS. These can be a bit confusing to the uninitiated, so heres the whole idea behind aux sends and returns: sends are outputs and returns are inputs. AUX SENDs tap signals off the channels, via the AUX knobs (14), mix these signals together, then send them out the AUX SEND jacks (50).
ONYX 1620
These outputs are fed to the inputs of an external processor like a reverb or digital delay. From there, the outputs of this external device are fed back to the mixers AUX RETURN jacks (51). Then these signals are sent through the AUX RETURN level controls (30), and nally delivered to the MAIN MIX (38).
So, the original dry signals go from the channels to the MAIN MIX and the affected 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!
The AUX SENDS can also be used to provide another mix for stage monitors, for example. In this case, the AUX RETURNS aren’t used to return the signal. Instead, they can be used as additional stereo inputs.
so you can control the monitor levels independently from the MAIN MIX. Use a post-fader send for effects, so that the wet signal level follows the dry signal level.
Most other mixing consoles require you to assign the pre/post function in pairs (Aux 1/2, Aux 3/4), which can be very limiting if you want to provide three monitor sends and one effects send, for example. The Onyx 1620 allows you to assign the pre/post function for each AUX SEND individually.
Both pre- and post-fader sends are affected by the EQ controls (unless the EQ is bypassed, of course).

30. AUX 1-4 RETURNS

These four controls set the overall level of effects received from the stereo AUX RETURN 1-4 inputs (51). These controls range from off () to +10 dB of gain when fully clockwise, to compensate for low-level effects.
Signals passing through the AUX RETURN level con­trols proceed directly to the MAIN MIX bus where they are combined with the other channels just before the MAIN MIX fader (38).

31. FX TO MON Switch

28. AUX 1 -4 MASTERS

The AUX MASTERS provide overall control over the AUX SEND levels, just before they are delivered to the AUX SEND outputs (50). These knobs go from off () to +15 dB when turned all the way up.
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, youd turn the knob down, but that never happens.)

29. AUX 1-4 PRE/POST

The PRE/POST switches determine whether the AUX SEND signal is tapped from the channel before the fader (pre-fader) or after the fader and MUTE button (post­fader). Typically, you use a pre-fader send for monitors

This switch routes the signal from AUX RETURN 3 to the AUX 1 SEND instead of the MAIN MIX bus. 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 3 jacks are combined with the signals coming from all of the channel AUX 1 send controls.

TALKBACK Section

The talkback feature allows the engineer to commu­nicate with the talent either through the PHONES (24) output or the AUX 1-2 (50) outputs. A talkback micro­phone is built into the Onyx 1620, or you have the option of connecting an external microphone at the TALKBACK MIC XLR (47) connector on the rear panel, which may be preferable in live or noisy situations.

37. TALKBACK Switch

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

33. TALKBACK LEVEL

Use this knob to control the level of the talkback signal being routed to the PHONES or AUX 1-2 outputs. This controls the talkback level for either the internal or external TALKBACK MICs.
You should start with the TALKBACK LEVEL control turned down, and then slowly turn it up until you get confi rmation from whoever is listening to headphones or monitors that they can hear you. Once you have set the level, you can leave it there for the duration of the session (or the gig).

34. EXTERNAL MIC Switch

If you are in a noisy environment, the built-in talkback mic may not work as well because it picks up the ambi­ent noise as well as your voice. You will probably have better results if you use an external microphone that you can talk directly into.
If you are using an external mic, you must push in the EXTERNAL MIC switch. The indicating LED lets you know when the switch is pushed. When the switch is out, the built-in TALKBACK MIC is used, regardless of whether or not you have an external mic plugged in. When the switch is pushed in, the built-in mic is discon­nected and only the external mic is used.
This is a momentary switch, meaning its only active when you hold the switch down. As long as you hold this switch down, the talkback signal is routed to the outputs determined by the destination switches (35/36). Release the switch, and the talkback circuit is turned off.

When the talkback circuit is activated (by pushing the TALKBACK (37) switch) and the CR/PHONES switch is in, the CONTROL ROOM outputs are attenuated by 20 dB to allow the engineers voice to come through loud and clear.

36. TALKBACK to AUX 1-2

This switch routes the talkback signal to the AUX 1 and 2 outputs (50). Use this to communicate with the musicians on-stage through their monitors during a live performance.
By the way, it is okay to have both destination switch­es pushed in at the same time. The talkback signal will be routed to both destinations. But if you dont have ei­ther of the destination switches pushed in, the talkback signal wont go anywhere. You might as well be talking to a brick wall.
When the fader is fully down, the MAIN MIX is off. The “U” marking indicates unity gain, and fully up provides 10 dB of additional gain. Typically, this fader is set near the U label and left alone, but it can be used for song fade-outs or quick system-wide mutes.

Front Panel Connectors

Besides the channel strip MIC and LINE input con­nectors, there are some other connectors located on the front panel for easy access.

40. CONTROL RM Outputs

ONYX 1620
These 1/4" TRS jacks provide a balanced line-level sig­nal that can be used to provide another main mix output (with MAIN MIX selected in the CONTROL ROOM/ PHONES SOURCE), or to monitor the ALT 3-4 outputs, TAPE inputs, or a 2-track feed from your computer (with the optional FireWire card installed).
Connect these outputs to the inputs of an amplifi er, powered speaker, or recording device.

41. 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 amplifi er, powered speaker, or recording device.
Note: The ALT 3-4 OUT doesn’t have a master level control. All the channels assigned to the ALT 3-4 bus are summed together (post-fader and pan) and sent directly to the ALT 3-4 OUT.
The TAPE IN jacks accept an unbalanced signal from a tape recorder or other signal source (could be a CD player, if you want) using standard hi-fi hookup cables. The signal is routed to the CONTROL ROOM/PHONES SOURCE matrix (20). Push in the TAPE button to route the tape input to the CONTROL ROOM and PHONES outputs (40/24). This allows you to playback recordings of your mixes.
Push in the ASSIGN TO MAIN MIX button (21) to route the tape input to the MAIN OUTs (48/42). This allows
you to playback music between sets over the

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.
The TAPE OUT jacks produce an unbalanced signal that is tapped off the MAIN OUTs. Normally, you would connect these to the inputs of a recorder, but you can use them as an extra set of main outputs for feeding another zone, for example.

These 1/4" TRS output connectors provide balanced or unbalanced line-level signals. This is the same signal that appears at the XLR MAIN OUTPUTS (48) on the rear panel. Connect these to the next device in the sig­nal chain like an external processor (graphic equalizer or compressor/limiter), or directly to the inputs of the main amplifi er.

Owner’s Manual

50. AUX SEND 1-4

This is a standard 3-prong IEC power connector. Con­nect the detachable linecord (included in the box with your Onyx 1620) to the power receptacle, and plug the other end of the linecord into an AC outlet. The Onyx 1620 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! This also means that it is less susceptible to voltage sags or spikes, providing greater electromagnetic isolation and better protection against AC line noise.

47. TALKBACK MIC

This is where you plug in your external talkback microphone if you need to have one. This female XLR connector has +48 VDC phantom power always applied, so you can use dynamic or condenser microphones.
Note: Almost all dynamic microphones can be used with phantom power, but you might want to check the docu­mentation that came with your microphone to be sure.

48. RIGHT/LEFT MAIN OUTPUTS

These 1/4" TRS output connectors provide balanced or unbalanced line-level signals for connecting to the inputs of effects devices or stage monitor amplifi ers.

51. AUX RETURN 1-4

These 1/4" TRS input connectors accept balanced or unbalanced line-level stereo signals from an external processor or other device. The stereo AUX RETURNS use jack normalling, like the stereo inputs on channels 9-16. If a signal is plugged into the LEFT (MONO) side and nothing is plugged into the RIGHT side, the signal is automatically connected to both LEFT and RIGHT sides. As soon as something is plugged into the RIGHT side, the normalled connection is broken and the LEFT and RIGHT inputs become stereo inputs (LEFT goes to the LEFT MAIN OUT and RIGHT goes to the RIGHT MAIN OUT).

52. CHANNEL INSERT

These 1/4" TRS jacks provide a send and return point for channels 1-8. Use the CHANNEL INSERT jacks to connect serial effects devices such as compressors, equalizers, de-essers, or fi lters to each individual channel.
These male XLR connectors provide a balanced line­level signal that represent 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 amplifi ers, powered speakers, or serial effects proces- sor (like a graphic equalizer or compressor/limiter). It provides a fully balanced signal that is the same as the 1/4" TRS MAIN OUT jacks on the front panel.

49. MAIN OUTPUT LEVEL

When this switch is out (+4 dB), the XLR MAIN OUTPUTS provide a +4 dBu line-level signal. When the switch is pushed in (MIC), the signal is attenuated by 40 dB to a microphone level. You can connect the XLR MAIN OUTPUTS to the microphone inputs of another mixer, providing a submix for keyboards or drums, for example, in a live sound application.
Note: You can safely plug this output into a micro­phone input that provides 48 V phantom power.

Besides being used for inserting external devices, these jacks can also be used as channel direct outputs; post-TRIM, post-LOW CUT, and pre-EQ. This is an unbalanced direct out, in contrast to the RECORDING OUTS on the rear panel, which are balanced direct outputs, post-TRIM, pre-LOW CUT.
Here are three ways you use the INSERT jacks:

connect a compressor or other dynamics processor to the INSERT jack, and adjust the channel fader to suit your live mix, but it has no effect on the signal going to the recorder. This provides maximum fl exibility for the mixdown stage.
See Appendix B for a wiring diagram of these connectors.

54. FIREWIRE I/O OPTION

Okay, we saved the best for last. FireWire (a.k.a. IEEE
1394) is a high-speed serial I/O interface for connecting digital devices, with more than 30 times the bandwidth of USB 1.1. You can install the optional Onyx FireWire interface card in this slot, which provides three FireWire connectors for transferring digital audio to and from your laptop computer or digital audio workstation (DAW) with absolute zero latency.
The FireWire interface provides the direct outputs for all sixteen channels and the Left/Right Mix. The Left/Right Mix is pre-fader at the FireWire output, so its level is independent of the MAIN MIX fader (important for live gigs). Instead, it has a rotary level control that provides 10 dB of boost or cut for the Left/Right mix, to optimize the level for the recorder or DAW. Use the FireWire interface to record a live performance directly to your
laptop, which you can mixdown to a stereo mix later. Or you can use it to turn your Onyx mixer into a high-quality
computer audio interface for your DAW.

53. RECORDING OUTS

These two DB-25 connectors provide balanced direct outputs for channels 1-8 and 9-16, respectively. They are designed to be connected directly to a recorders analog inputs, and use the TASCAM standard pinout for analog signal connections (the same standard used on the ana­log cards for the Mackie D8B and Hard Disk Recorder).
The signal at the RECORDING OUTS comes just after the input GAIN control, and before the Low-Cut switch, INSERT jacks, and EQ. This way you can EQ a channel,

Appendix A: Service Information

Warranty Service

Owner’s Manual
Details concerning Warranty Service are spelled out in the Warranty section on page 31.
If you think your Onyx mixer has a problem, please do everything you can to confi rm it before calling for service. Doing so might save you from the deprivation of your Onyx mixer and the associated suffering.
These may sound obvious to you, but here are some things you can check. Read on.

Troubleshooting

No Power
Our favorite question: Is it plugged in?
Make sure the power cord is securely seated in the
IEC socket (46) and plugged all the way into the AC outlet.
Make sure the AC outlet is live (check with a tester or lamp).
Is the POWER (45) switch on? Make sure the POWER switch on the rear panel is in the ON posi­tion (up).
Is the POWER LED (39) on the front panel illumi- nated? If not, make sure the AC outlet is live. If so, refer to No Sound below.
Are all the lights out in your building? If so, contact your local power company to get power restored.
If the POWER LED is not illuminated, and you are certain that the AC outlet is live, it will be to have your Onyx 1620 serviced. There are no user serviceable parts inside. Refer to Repair at the end of this section to fi nd out how to proceed.
Bad Channel
Is the MUTE/ALT 3-4 button (16) in the correct position?
Is the input GAIN control (7) for the channel turned up?
necessary
Is there something plugged into the CHANNEL INSERT jack (52)? Try unplugging any INSERT devices (channels 1-8 only).
Try the same source signal in another channel, set up exactly like the suspect channel.
Bad Output
Is the associated level control (if any) turned up?
If it’s one of the MAIN OUTPUTS, try unplugging all
the others. For example, if its the 1/4" LEFT MAIN OUT, unplug the RCA LEFT TAPE OUT and XLR LEFT OUTPUT. If the problem goes away, it’s not the mixer.
If it’s a stereo pair, try switching them around. For example, if a left output is presumed dead, switch the left and right cords at the mixer end. If the problem stays on the left side, its not the mixer.
Bad Sound
Is the input connector plugged completely into the jack?
Is it loud and distorted? Make sure the input GAIN control for the input is set correctly. Reduce the signal level on the input source if possible.
If possible, listen to the signal with headphones plugged into the input source device. If it sounds bad there, its not the Onyx causing the problem.
Noise/Hum
Turn down the AUX RETURN knobs (30). If the noise disappears, its coming from whatever is plugged into the AUX RETURNS (51).
Turn down each channel, one by one. If the noise disappears, its coming from whatever is plugged into that channel.
Check the signal cables between the input sources and the Onyx. Disconnect them one by one. When the noise goes away, youll know which input source is causing the problem.
Is the fader (17) turned up?
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 (18) LEDs next to the channels fader.
If it is channel 1 or 2, make sure the MIC/HI-Z switch (4) is in the right position.
Sometimes it helps to plug all the audio equipment into the same AC circuit so they share a common ground.

Unbalancing a Line

In most studio, stage, and sound reinforcement situ­ations, there is a combination of balanced and unbal­anced inputs and outputs on the various pieces of equipment. This usually will not be a problem in making connections.
When connecting a balanced output to an unbal- anced input, be sure the signal high (hot) connec­tions are wired to each other, and that the balanced signal low (cold) goes to the ground (earth) connection at the unbalanced input. In most cases, the balanced ground (earth) will also be connected to the ground (earth) at the unbalanced input. If there are ground-loop problems, this connection may be left disconnected at the balanced end.
Owner’s Manual
23
Page 24
When connecting an unbalanced output to a bal- anced input, be sure that the signal high (hot) connections are wired to each other. The unbal­anced ground (earth) connection should be wired to the low (cold) and the ground (earth) connec­tions of the balanced input. If there are ground-loop problems, try disconnecting the unbalanced ground (earth) connection from the balanced input ground
ONYX 1620
(earth) connection, leaving the unbalanced ground connected to the balanced input low (cold) con­nection only.
In some cases, you may have to make up special adapters to interconnect your equipment. For example, you may need a balanced XLR female connected to an unbalanced 1/4" TS phone plug. Many common adapters can be found at your local electronics supply store.
The balanced-to-unbalanced connection has been anticipated in the wiring of Mackie jacks. A 1/4" TS plug inserted into a 1/4" TRS balanced input, for example, will automatically unbalance the input and make all the right connections. Conversely, a 1/4" TRS plug inserted into a 1/4" unbalanced input will automatically tie the ring (low or cold) to ground (earth).
This allows you to tap out the channel’s signal at that
point in the circuit without interrupting normal operation.
Note: Do not overload or short-circuit the signal you are tapping from the mixer. That will affect the internal signal.
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.

TRS Send/Receive Insert Jacks

Mackies single-jack inserts are three-conductor 1/4" TRS phone jacks. They are unbalanced, but have both the mixer output (send) and mixer input (return) signals in one connector.
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 1/4" TS (mono) plug only partially (to the fi rst 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).

A mult or Y connector allows you to route one output to two or more inputs by simply providing parallel wir­ing connections. You can make Ys and mults for the outputs of both unbalanced and balanced circuits.
Remember: Only mult or Y an output into several inputs. If you need to combine several outputs into one input, you must use a mixer, not a mult or a Y.

This warranty applies only to equipment sold and delivered within the U.S. by LOUD Technologies Inc. or its authorized dealers.
B. Failure to register online or return the product registration card will not void the three-year warranty.
C. Service and repairs of Mackie products are to be performed only at a factory-authorized facility (see D below). Unauthorized
service, repairs, or modifi cation will void this warranty. To obtain repairs under warranty, you must have a copy of your sales receipt from the authorized Mackie dealer where you purchased the product. It is necessary to establish purchase date and determine whether your Mackie product is within the warranty period.
D. To obtain factory-authorized service:
1. Call Mackie Technical Support at 800/898-3211, 7 AM

2. Pack the product in its original shipping carton. Also include a note explaining exactly how to duplicate the problem, a copy of the sales receipt with price and date showing, and your return street address (no P.O. boxes or route numbers, please!). If we cannot duplicate the problem or establish the starting date of your Limited Warranty, we may, at our option, charge for service time.
3. Ship the product in its original shipping carton, freight prepaid to the authorized service center. The address of
your closest authorized service center will be given to you by Technical Support.
IMPORTANT: Make sure that the Service Request Number is plainly written on the shipping carton.
E. LOUD Technologies reserves the right to inspect any products
that may be the subject of any warranty claims before repair or replacement is carried out. LOUD Technologies may, at our option, require proof of the original date of purchase in the form of a dated copy of the original dealer’s invoice or sales receipt. Final determination of warranty coverage lies solely with LOUD Technologies.
F. Any products returned to one of the LOUD Technologies factory-authorized service centers and deemed eligible for repair or replacement under the terms of this warranty will be repaired or replaced within thirty days of receipt. LOUD Technologies and its authorized service centers may use refurbished parts for repair or replacement of any product. Products returned to LOUD Technologies that do not meet the terms of this Warranty will be not be repaired unless payment is received for labor, materials, return freight, and insurance. Products repaired under warranty will be returned freight prepaid by LOUD Technologies to any location within the boundaries of the USA.
G. LOUD Technologies warrants all repairs performed for 90 days or for the remainder of the warranty period. This warranty does not extend to damage resulting from improper installation, misuse, neglect or abuse, or to exterior appearance. This warranty is recognized only if the inspection seals and serial number on the unit have not been defaced or removed.
H. LOUD Technologies assumes no responsibility for the quality or timeliness of repairs performed by an authorized service center.
I. This warranty is extended to the original purchaser and to anyone who may subsequently purchase this product within the applicable warranty period. A copy of the original sales receipt is required to obtain warranty repairs.
J. This is your sole warranty. LOUD Technologies does not authorize any third party, including any dealer or sales representative, to assume any liability on behalf of LOUD Technologies or to make any warranty for LOUD Technologies Inc.
K. THE WARRANTY GIVEN ON THIS PAGE IS THE SOLE WARRANTY GIVEN BY LOUD TECHNOLOGIES INC.
