EFX TO MON
Use this control to add the EMAC internal
effects (or external effects, if connected) to the
monitor mix. The effects signal is added to the
monitor signal path just prior to the
RUMBLE
REDUCTION
switch and the MONITOR
MASTER
control.
The
EFX TO MON control ranges from off
through unity (the center detent position) on
up to +10 dB of extra gain.
MONITOR MASTER
This controls the overall signal level at the
MONITOR LINE OUT . The control ranges from
off through unity on up to +12 dB of extra gain.
Turning up the
MONITOR
MASTER
too much can
cause feedback. To reduce
the possibility of feedback,
try to position the micro-
phones so they are pointing away from the
stage monitors. This will minimize the amount
of monitor signal that is picked up by the
microphones.
EFX TO MAIN
Use this control to add the EMAC internal
effects (or external effects, if connected) to
the main mix. The effects
signal is added to the main
signal path just after the
RUMBLE REDUCTION switch
and just prior to the
MAIN
MASTER
control.
The
EFX TO MAIN control
ranges from off through unity
(the center detent position) on
up to +10 dB of extra gain.
MAIN MASTER
This controls the overall sig-
nal level at the
MIXER LINE
OUT
(s) and at the input to
the power amplifiers. The con-
trol ranges from off through
unity on up to +12 dB of extra
gain.
LEVEL Meters
These 8-segment LED meters
indicate the
signal level at the
MONITOR LINE OUT
and the MIXER LINE OUT . To attain the
best signal-to-noise ratio while still maintain-
ing adequate headroom, set the
MONITOR
MASTER
and MAIN MASTER controls so the
0 dB indicator on the
LEVEL meters blinks
frequently. It’s okay for the +5 dB indicator to
blink occasionally, but avoid allowing the
CLIP
indicator to light. Clipping occurs at a +20 dBu
output level.
PHANTOM POWER Switch
Push in this switch to provide phantom
power to the XLR
MIC input connectors. All of
the XLR mic inputs are capable of providing
phantom power. Phantom power is required
to operate most condenser microphones
(some condenser microphones are battery-
powered). The PPM Series provide +15V DC
phantom powering on pins 2 and 3 of the XLR
connectors.
If you are using condenser microphones, or
any mic that requires phantom power, engage
the
PHANTOM POWER switch (located just
below the
EMAC section). If you have dynamic,
ribbon, or tube mics that do not require phan-
tom power, leave the
PHANTOM POWER
switch out. If you are using both condenser and
dynamic mics, don’t worry. Phantom power will
