D. Two INPUT jacks: Two channels, balanced, kΩ

minimum input impedance.

E. Two INPUT LEVEL switches: One for each input

channel. Switches between -0 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 LF output only

when in Bass Mono Sum.

Rear panel of both the 40

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 /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 -8 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- 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.
