Check the power
source for the voltage
(115VAC or 230VAC) in
your area and switch
the Power Selector
switch (40) to select
the proper voltage.
Once you have con-
nected the AC power
cord (39) to the AC
power source, switch
on your mixer with the
Power On switch (36).
The Power ON LED
(20) will light up. Allow
1 minute after power-
ing up for the system
to reach equilibrium
before setting input
gains and other levels.
You can leave the
MXE-1212 on all the
time. It is conservative-
ly designed, so heat
build-up isn’t a problem
even in 24-hour-a-day
operation. There’s
nothing that will burn
out or get used up.
Alternatively, you can
just plug every unit in
your total system into a
Nady Power
Conditioner PCL-
800/810/815 or a good
quality power strip, for
one-button turn-on.
The MXE-1212 is
fused for your (and its
own) protection. If a
fuse blows, disconnect
the AC cord, and
replace the fuse with a
2.0A (5x20mm, 250V)
type, available at elec-
tronics stores or
through your dealer. If
the fuse blows continu-
ously upon replace-
ment, unplug the unit
and refer to qualified
personnel for servicing
before further use.
(38) PHANTOM POWER SWITCH
(21) PHANTOM POWER ON LED INDICATOR
When using condenser mics, +48VDC can be switched glob-
ally on or off to the XLR mic inputs for all six channels (also
see MONO INPUT SECTION, MIC INPUTS). When this
switch is in the ''ON'' position (button depressed), the
Phantom Power On LED Indicator (21) will light, and
+48VDC will be provided between pins 2 and 3 of all the Mic
input XLR connectors. If you don’t need phantom power, be
sure to turn this switch to the ''OFF'' position.
[Note: It is safe to connect balanced dynamic mics or line
level devices even if this switch is on, but connecting unbal-
anced devices or devices whose transformers are center-
grounded will cause hum or malfunctions. Shorting the
+48VDC can also damage your mixer. Also, turn down the
Stereo Master faders (25A, 25B) to prevent possible sharp
transient noise from damaging the speakers when turning the
phantom power on or off.]
