Mixer Controls
Mic Section
MIC LEVEL
sets the gain of the
Mic Input. The range is off to +44
dB. There is no engage switch, so
set the Mic Level to zero (0) when
you aren't using it. The Mic Input
minimum gain is 26 dB, so a line-
level mic source (such as a wireless
receiver) must be padded.
The
OL
indicator lights 6 dB
before clipping. Adjust the Mic
Level so the OL indicator flashes
only when you really shout into
the mic.
MIC HIGH
and
LOW
tone
controls provide as much as
12
dB
of boost or
12
dB of cut. These
controls have no effect when the
controls are set to their center
detent (12 o'clock).

Program Sections
PGM 1
inputs are sent to the left side of the crossfader. (with the
Fader 1 Reverse switch
out
and LED
off
)
PGM 2
inputs are sent to the right side of the crossfader.
(with the Fader 2 Reverse switch
out
and LED
off
)
SOURCE
switches select which inputs are assigned to each
of the Programs. PGM 1 can switch between inputs 1 and 2.
PGM 2 can switch between inputs 3 and 4.
GAIN
controls adjust the signal level before it gets to the
Faders. Set the Gain controls to indicate an average signal level
of +4 on the meter with the program faders set to maximum.
Don't use the Gain controls to set the output level...use the Main
Level control to set the output level. This is a very simple thing,
yet makes a huge difference in mixer performance.
EQ
switches engage the 3-band tone controls. EQ switches
may be used in conjunction with the High, Mid and Low con-
trols as “kill” switches by turning any or all of them Off. Set the
rotary controls and flip the switch.
