Whirlwind's THS 1T is a Push to Talk sports announcer box with single button mic control. THS boxes are ergonomically designed to put the control buttons within easy reach of the announcer even while shuffling through stat sheets. The headphone amplifiers are designed to deliver powerful, undistorted audio that can be heard over an arena full of screaming fans.

The THS 1T Talkback/Headphone box is configured with a single momentary Push to Talk switch to control the microphone output. The microphone output of the THS 1T box is a passive, straight through connection from the microphone input. This ensures that the microphone will still be live on-air, even if power to the THS 1T is lost. A jack is provided for connection of an optional momentary footswitch to control the mic operation. For use with dynamic mics only.

Headphone inputs consist of balanced left and right inputs on separate female XLR connectors. A single front panel volume control adjusts the level of both the left and right earpieces. Another balanced mono Aux input is provided which feeds left and right ears equally. The Aux input has it's own volume control. Headphones with impedances ranging from 30 to 600 Ohms can be driven to full volume.

Power is supplied by the included 12 VAC power adapter (model no. PS12AC1A).

Whirlwind THS 1T Talkback/Headphone Box Features:

  • Balanced XLR input and output jacks
  • Microphone Control switches (PTT and PTM) are completely silent
