MONO/SUBWOOFER Output Section - continued
58 - SUBWOOFER ON/OFF – switch
Used to engage the Low Pass Filter and turn the
MONO output into a subwoofer output.
59 - FREQUENCY – control knob
The L Series mixers have an onboard Low Pass Filter
to make it simple to connect a subwoofer. Use the
FREQUENCY control to adjust the crossover point
for the Low Pass Filter in a range of 20 Hz to 200 Hz.
The FREQUENCY control knob is active when the
SUBWOOFER ON/OFF switch is set to ON.
60 - AFL - switch
The MONO output’s AFL, or After Fader Listen switch
allows you to listen to, or “solo”, the MONO signal
in the headphones. When the MONO AFL switch
is pressed down, the left/right mix will be heard in
headphones plugged in to the PHONES connector
located in the front panel jack field. Since the signal
is sent after the MONO level fader, you hear the
signal with the added gain from the MONO Level
control.
61 - MONO - fader control
The MONO level fader control is used to adjust the
volume of the signal connected to the MONO/SUB
output.

MAIN Output Section
62 - MAIN MIX B – control knob
The L Series mixers provide a second set of output
connectors carrying a duplicate of the MAIN MIX
signal for the purpose of feeding another speaker
zone or recorder. The MAIN MIX B control knob is
used to set the volume of the MAIN Mix B output.
63 - AFL (MAIN MIX) – switch
The MAIN MIX output’s AFL, or After Fader Listen
switch allows you to listen to, or “solo”, the MAIN MIX
in the headphones. When the MAIN MIX AFL switch
is pressed down, the left/right mix will be heard in
headphones plugged in to the PHONES connector
located in the front panel jack field. This allows you
to listen to the stereo mix , (let’s say), to check that
a signal is not distorted before it gets to the power
amplifier. Since the signal is sent after the MAIN MIX
level fader, you hear the signal with the added gain
from the MAIN MIX Level control.
64 - MAIN MIX (left and right) - Level fader
The MAIN MIX Level fader adjusts the level of MAIN
left and right stereo mix.
