. Power Connection
This is a standard 3-prong IEC power connector.
Connect the detachable line cord (included in the box
with your mixer) to the power receptacle, and plug the
other end of the line cord into an AC outlet.
Onyx Series mixers have a universal power
supply that accepts any AC voltage ranging from
00 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.
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 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 turn the mixer
o. It will not work at this point, but makes a handy
paperweight.
As a general guide, you should turn
on the mixer first, before any external
power amplifiers or powered speakers,
and turn it o last. This will reduce the possibility
of any turn-on, or turn-o thumps in your speakers.

3. USB Input / Output
In addition to being a mixer, the Onyx Series also
acts as a high-resolution interface that allows audio
to stream to and from the mixer via computer. As seen
below, they allow for some powerful and flexible routing.
• Onyx8 – 8x4, 24-bit / 96 kHz
• Onyx2 – 4x4, 24-bit / 96 kHz
• Onyx6 – 8x4, 24-bit / 96 kHz
• Onyx24 – 24x4, 24-bit / 96 kHz
This allows you to record all input channels
to the computer via USB and/or return two independent
audio streams of stereo playback from a computer.
The USB routing capabilities are as follows:
USB input TO the mixer – playback:
() A USB -2 switch is located on the third to last
stereo channel – the channel directly to the lef of the
one with the USB 3/4 switch – of each mixer, so one
may route the computer’s DAW output (such as Pro
Tools®, Tracktion®, Cubase®, Reaper®, etc.) to the mixer
and blend that signal with the live inputs of the mixer
in the headphones for latency-free monitoring.
(2) A USB 3-4 switch is located on the second to
last stereo channel – the channel directly to the lef of
the one with the /8" input – of each mixer, so one may
route computer output (such as Spotify®, Apple Music®,
Pandora®, YouTube®, etc.) down this stereo channel.
This stereo signal may then be EQ’d, sent to auxiliaries
(i.e. to feed monitors, headphones or eects) and is
routable to mains via the fader routing features that are
available on all other channels. In short, this signal may
be sent to nearly any desired output or pair of outputs.
Additionally, the associated gain knob adjusts the USB
input level to the mixer to achieve an optimal signal
level.
USB output FROM the mixer – recording, etc:
It is possible to record the main mix to take home
a copy of the live show. These levels are pre-main fader.
Therefore, levels may be mixed up or down in the DAW
later depending on the needs of the recording versus
the live show. The end result is that fade-ins and/or
fade-outs made during the show do not aect recorded
levels.
