Power Switch
Press the top of this rocker switch in to turn the mixer on and
press the bottom of this switch to turn the
mixer o.
As a general guide, the mixer should be turned on rst, before any external power ampliers
or powered speakers. As such, it should also be turned o last. This will reduce the possibility
of any turn-on or turn-o thumps in the PA.
Power LED
This LED will illuminate green when the mixer is turned on
. If it does not turn on, conrm that The Power
Block and line cord are connected correctly (to each other, the mixer and the AC outlet), the local AC mains
supply is active and that the power switch is on.
Phantom Power Switch
Press the top of this rocker switch in if any microphone requires phantom power. (Always check the position
of this switch before connecting microphones.) This is a global switch that aects all mic channels’ XLR jacks
at once.
Press the bottom of this switch in to turn the phantom power o.
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. (Semi-pro
condenser mics often have batteries to accomplish the same thing.) “Phantom” owes its name to an
ability to be “unseen” by dynamic mics [Shure SM57 / SM58, for example], which do not need external
power and are not aected by it, anyway.
Never plug single-ended (unbalanced) or ribbon microphones into the mic input jacks
when phantom power is on. Do not plug instrument outputs into the mic XLR input jacks
with phantom power on unless you know for certain that it is safe to do. When phantom
power is engaged, be sure that the master fader is down when connecting microphones
to the mic inputs to prevent pops from getting through the PA.
It is not a good idea to enable the phantom power unless it is actually needed. Line-level
sources may be particularly unhappy when they are subjected to 48V phantom powering.
Many musical instrument amps and keyboards with “direct outputs” t this description.
It takes approximately 15 seconds for the phantom power to shut o completely.
Do not add or remove any inputs until the phantom power LED is completely o
or mics could be ruined.
