Basic Microphone / Speaker Interface Block Diagram (Transformers not shown for clarity)
Each input can be routed to an output or all outputs by placing routing jumpers inside the unit as desired.
The CI-BUSS interface performs the same function for additional units. The Microphone is processed
with ALC to be of constant level and passed to other Units in both directions as selected.
The ALC has an indicator for the Threshold of Limiting.
This indicator also serves as a setup indicator for adjusting the Microphone level.
