27. Power switch
This switches the mixer on and off.
28. Phantom power switch
This a48V of phantom power to the XLR
mic inputs. it's been mentioned before, but
MAKE SURE THERE IS NO EQUIPMENT
PLUGGED INTO THE XLR INPUTS THAT
WILL BE DAMAGED BY THE APPLICATION
OF +48V OF PHANTOM POWER. ONLY CER-
TAIN TYPES OF CONDENSER MIC REQUIRE
S U C H E X T E R N A L P O W E R . A S A
PRECAUTION, WAIT UP TO A MINUTE AF-
TER SWITCHING OFF THE PHANTOM
POWER BEFORE CONNECTING ANY NEW
DEVICES, BECAUSE THE ACTUAL LEVEL
CAN TAKE A WHILE TO DROP TO ZERO.
Notice that the phantom power switch is small
and different to the main switch. This ensures
that it is not flicked accidentally, or mistaken
for the main power switch when you want to
switch off.
29. Ch1 & 2 Insert switches
The inserts on the first two channels may be
switched pre or post fader. When in the pre
position, the signal is tapped just before the
EQ, which is the traditional place for certain pro-
cessors like compressor/limiter and external
equalizers. Sometimes processing such as lim-
iting may be wanted post fader, or a reverb on
just one channel may be required.
In these cases, the inserts can be used post-
fader, The inserts on channels 3 and 4 are fixed
pre-fader.
These inserts can also serve as direct outputs
for four-track recording. A mono (TS) plug in-
serted all the way into the second click will inter-
rupt the signal and route it out through the jack.
This can be sent to the recording device and re-
turned for monitoring using the four stereo chan-
nels (use only left input per stereo channel for
this). For more details see Hook-ups: Channel
Inserts, beginning page 11.
30. Power cable
This cable carries mains voltage to the mixer's
internal power supply. It is more durable than
flimsy cables with external supplies, but some
precautions are necessary. Ensure that the
cable isn't pulled, or that nothing heavy that
might damage the cable is resting on it.
