Whirlwind

The Whirlwind THS R Talkback/Headphone Box is a high-performance sports announcer console designed for seamless integration with RTS IFB systems. Built for reliability in live broadcasting environments, the THS R ensures clear communication, precise control, and uninterrupted on-air performance. Main and Talkback microphone outputs are provided, with Cough and Talkback switches for control. The Talkback output is line level with volume control, and the main microphone output of the THS R will remain live on-air if power is lost, when using dynamic microphones.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, depending on the current available from the IFB line. 600-ohm headphones can be used with a slight reduction in volume.The RTS-compatible THS R has both main and Talkback microphone outputs. The microphone signal is always live at the main output unless the Talkback or Cough switch is depressed. If power to the THS R is lost, the mic signal will still pass with dynamic mics and with condenser mics if phantom power is provided from the host console. Two types of onboard condenser microphone power are available, enabling seamless switching when Talkback is activated. A three-way switch selects either phantom or "T" power and is recessed to avoid accidental turn off. A momentary Cough switch silences both the mic out and the Talkback out when depressed. The announcer's microphone signal is sent through a preamp and a line-level signal to the Talkback output when the momentary Talkback switch is activated, and it also mutes the mic out.The THS R receives both power and input audio through a female-3 pin XLR from a "Wet" RTS compatible IFB system. Positive 24-30 VDC 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. When an input is assigned to both ears, level adjustments affect both left and right ears equally. Both 3.5mm and 1/4" TRS jacks are provided for hookup flexibility.Transformer isolation is provided for both IFB inputs and the Talkback output. The high-quality audio transformers provide signal and power isolation and ground-loop reduction for both the interrupt and non-interrupt inputs as well as line balancing for the Talkback output. The THS R can also be locally powered by a 12 VAC power adapter, model # PS12AC1A, included with the unit.At a Glance RTS compatible 3-pin XLR input configured for "Wet" IFB (24 to 30 VDC)Input assign switches route inputs to either or both earsIndividual volume controls for interrupt and non-interrupt inputsTransformer isolation on both inputs and talkback outPassive mic out for on-air reliabilityMic output switching is completely silentActive line-level talkback out with level adjustCough and talkback switches for controlPS12AC1A power adapter included for external power
