This is a standard 3-prong IEC power connector. Con-
nect 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.
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 docu-
mentation that came with your microphone to be sure.
These male XLR connectors provide a balanced line-
level 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.
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 micro-
phone input that provides 48 V phantom power.

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.
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).
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.
The INSERT points are after the GAIN and Low Cut
controls, but before the EQ and Fader controls. The
send (tip) is low-impedance, capable of driving any
device. The return (ring) is high-impedance and can be
driven by almost any device.
Special insert cables are available, specially designed
for this kind of insert jack. They are wired as follows:
ring
(TRS plug)
tip
sleeve
this plug connects to one of the
mixer's Channel Insert jacks.
Tip = Send (output to effects device)
Ring = Return ( input from effects device)
Sleeve = Common ground (connect shield to all
three sleeves)
