Onyx 1220i Features

Rear Panel

1. POWER CONNECTION

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
30
AC voltage ranging from 100 VAC to 240 VAC. No need for
U
20
voltage select switches. It will work virtually anywhere U
-

SEND
in the world. That's why we call it a "Planet-Earth" power
supply! It is less susceptible to voltage sags or spikes,
U
compared to conventional power supplies, and provides
- 15
1k
greater electromagnetic isolation and better protection
100
against AC line noise.

Disconnecting the plug's ground pin is danger-

2. POWER SWITCH

O O
Press the top of this rocker switch inwards to turn on
O O
the mixer. The front panel power LED [46] will glow
L
with happiness, or at least it will if you have the mixer
plugged into a suitable live AC mains supply.
MUTE
Press the bottom of this switch to put the mixer into
ALT 3/4
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 ampli-
fiers or powered speakers, and turn it off last.
This will reduce the possibilities of any turn-
SOLO
on, or turn-off thumps in your speakers.
