Whirlwind THS 3 Talkback Headphone Box

The THS 3 is a fully loaded sports announcer console. Both main and talkback microphone outputs are provided, with Mic On/Off, Cough and Talkback switches to control them. The talkback output is line level with its own trim control, and the main microphone output stays live on air if power is lost, when dynamic microphones are used.

There are two assignable headphone inputs with balanced and unbalanced connections, and each can be assigned to the left ear, the right ear or both. Left and right headphone amplifiers have individual volume controls setting the overall level in each ear, and headphones from 30 to 600 ohms can be driven to full volume.
