Quick Start Guide

Microphones
Connect your microphones to the female XLR
connectors on channels 1, 2, and 3-4. The microphone
preamps feature our Onyx design, with super high
fi delity and headroom. Professional ribbon, dynamic,
and condenser mics all sound excellent through these
inputs.
Microphone-level signals are passed through the
mixer's splendid microphone preamplifi ers to become
line-level signals. The mic input of hybrid channels 3-4
is fed equally to channels 3 and 4.
48V PHANTOM POWER
Press the 48V phantom power switch if your microphones
need it.
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.
Never plug single-ended (unbalanced) micro phones,
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 to do so.
LOW CUT
The mono and hybrid channels each have a low-cut
switch (often referred to as a high-pass fi lter) that
cuts bass frequencies below 75 Hz. This will reduce the
thumps and bangs due to stage noise and rumble, and
mic handling.
We recommend that you use low-cut on every
microphone application except kick drum, bass guitar,
or bassy synth patches.
Using the low cut switch also allows you to add some
bass EQ to your vocals without boosting the really-low
lows.
VOCAL EQUALIZATION
Mono channels 1 and 2 have a 3-band EQ, with
shelving-low, shelving-high and peaking-mid. The
frequency of the mid can be adjusted from 100 Hz to
8 kHz.
This extra detail in the mid EQ section is ideal for
vocal equalization, so you might consider using
channels 1 and 2 for your main vocal mics. Channel 3-4
has a 4 band EQ, with a high-mid and low-mid control.
INSERTS
Channels 1 and 2 have insert jacks that allow you to
send the mic and line signals out to an external device,
and back in again on the same connector. For example,
vocals benefi t from having an external vocal compressor.
These compress the level of the signals when they reach
a certain threshold, and help prevent overloading.
SETTING THE MICROPHONE GAIN
1. Press the solo switch at the bottom of the
channel your microphone is connected to. The
rude solo light will fl ash to remind you that
what you are listening to in the control room
and headphones, and shown on the main right
meter is the soloed channel.
2. Sing/talk/shout/scream into the microphone at
typical loudness levels.
3. Adjust the channel gain control until the right
main meter level is hovering around the 0 dB
mark (labeled "level set").
4. Now that the gain is set correctly, disengage
solo.
