Patching rules:
1.
Connect outputs to inputs.
2.
To "split" a signal for feeding to two or more inputs, patch from the output to be split
to the MULTIPLE. The remaining MULTIPLE jacks are now outputs.
3.
Combine module outputs with a MIXER.
4.
Control signals may not be patched into the audio signal path. However, audio signals
may be used as control signals.
5.
Patch only audio signals into signal input jacks. Exception: the 902 VOLTAGE
CONTROLLED AMPLIFIER, the 923 LOWPASS FILTER, and the lower panel
MIXER and REVERSIBLE ATTENUATOR, are capable of processing slowly-
varying control signals.
