OUR PART # THSR
The THS R Talkback/Headphone box is a specialized sports announcer console designed to operate with RTS® 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.
The THS R receives both power and input audio through a female 3 pin XLR from a "Wet" RTS® compatible IFB system. Positive 24-30VDC power and interrupt audio are on Pin 2 and non-interrupt audio is on Pin 3. Pin 1 is power ground and audio shield. The headphone section of the THS R has two inputs. Each input has a volume control and dip switches to send the signal to the left and/or right headphone earpieces. When an input is assigned to both ears, level adjustments affect both left and right ears equally. Both 3.5mm and ¼” TRS jacks are provided for hookup flexibility. Headphones with impedances ranging from 30 to 150 Ohms can be driven to full volume. 600 Ohm headphones can be used with a slight reduction in volume due to "Wet" IFB current limitations.
