contact closures between one of the Memory Preset terminals and ground. A momentary dry
contact between the ground and any one of the numbered connectors will instantly recall and
load the configuration stored in the memory location with the same number as the terminal.
INPUTS 1-12
- Provides the balanced, RF protected line level inputs into the CM12/8.
OUTPUTS 1-8
- Provides the balanced system outputs. The outputs may also be used in an unbal­
anced mode by connecting the "+" terminal of an output to the signal lead of the unbalanced
device, and the ground terminal of the an output to the ground of the unbalanced device. If an
unbalanced MIC level signal is required, it is necessary to connect the "-" terminal to the ground
terminal.
OUTPUT LEVEL DIP SWITCHES
This allows proper output level matching to mic level inputs, such as some types of tape recorders.

are interconnected.
RS-232 SERIAL PORT
