Whirlwind THS Pc Talkback Headphone System

The THS Pc is a producer station built for environments where IFB and intercom have to work together from one position. It manages program audio, talkback and microphone routing from a single desktop unit rather than from a stack of separate boxes.

That gives the producer flexible control over headphone and IFB distribution without reaching across the desk, which is the whole reason these are built as one unit.
