Whirlwind - THSR (Talkback Headphone Box)

The THSR Talkback/Headphone box is a specialized sports announcer console designed to operate with RTSr IFB systems. Main and talkback microphone outputs are provided, with Cough and Talkback switches for control. The talkback output is line level with a trim control and the main microphone output of the THS R will remain live on-air if power is lost, when using dynamic microphones.

Interrupt and non-interrupt headphone signals, as well as power for the THSR, are connected through a female 3 pin XLR connector. Each input signal has a volume control and assign switches to the left and/or right headphones. Input level adjustments affect both left and right ears equally.

The headphone amplifiers are optimized to work with impedances ranging from 30 to 150 Ohms due to the current available from the IFB line. 600 Ohm headphones can be used with a slight reduction in volume.
