D. Two INPUT jacks: Two channels, balanced, 2 kΩ
minimum input impedance.
E. Two INPUT LEVEL switches: One for each input
channel. Switches between -10 dB and +4 dB
sensitivity. (For specifications see Appendix B.)
F. MODE switch: Selects one of the three controller
operating modes (position 3, marked “NC” is not
used).
G. Two HIGH FREQ OUTPUT jacks: Two high
frequency output channels, balanced, low
impedance. These supply full bandwidth signals
to the amplifier(s) when the controller is in Full
Range mode.
H. Two LOW FREQ OUTPUT jacks: Two low
frequency channels, balanced, low impedance.
Signal is available at Channel 1 LF output only
when in Bass Mono Sum.
I. OUTPUT MODE switch: Choose the SUM
setting to combine the bass portion of the
signals from the two INPUT jacks (which are
usually stereo left and right). The controller
sends that combined signal to the first channel
CH 1/SUM jack of the LOW FREQ OUTPUTs.
J. LOW FREQ LEVEL control: Adjusts the level of
the signal from the LOW FREQ OUTPUT jacks.
You can choose any setting between -18 dB and
+3 dB.
K. AC cord jack: Connects to mains power outlet.
L. Protection circuit punch out: Works only
with an Acoustic Wave

II loudspeaker. This plug comes out when
installing the OC-1 option card for systems that
use the AWCS II loudspeaker as the bass.
M. Chassis ground lug: Use for attaching a
terminal lug to the ground(s) of other equipment
in the system.
