Whirlwind THS R Talkback Headphone Box

Make your audio performances and recordings seamless with the THS R Talkback Headphone Box, a high-quality, compact, and user-friendly device designed specifically for sports announcers and audio professionals. This durable and reliable product is engineered to function with RTS IFB systems, ensuring smooth and uninterrupted audio output.

The THS R Talkback Headphone Box features both main and talkback microphone outputs, equipped with Cough and Talkback switches for optimal control. The talkback output is line level with a trim control, ensuring that the main microphone output remains live on-air, even in the event of power loss when using dynamic microphones.

This device is designed with a female 3-pin XLR connector, which facilitates the connection of interrupt and non-interrupt headphone signals, as well as power for the THS R. Each input signal comes with a volume control and assign switches for the left and/or right headphones, with input level adjustments impacting both ears equally. The headphone amplifiers are optimized to work with a wide range of impedances, from 30 to 150 Ohms, due to the current available from the IFB line. Even 600 Ohm headphones can be used, albeit with a slight reduction in volume.

The THS R Talkback Headphone Box is RTS compatible and ensures that the microphone signal is always live at the main output unless the Talkback or Cough switch is activated. In case of power loss, the mic signal will still pass with dynamic mics and with condenser mics if phantom power is provided from the host console.

This device also features two types of onboard condenser microphone power, 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 headphone section of the THS R has two inputs, each with a volume control and dip switches to send the signal to the left and/or right headphone earpieces. Both 3.5mm and 1/4" TRS jacks are provided for hookup flexibility.

The THS R Talkback Headphone Box also offers transformer isolation 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.

This device can be locally powered, with a rear panel switch selecting "Wet" IFB or external power supplied by a 12 VAC power adapter, model # PS12AC1A, included with the unit. The typical current consumption from the IFB line is 85mA, with a maximum draw of 110mA.

In summary, the THS R Talkback Headphone Box is a compact, durable, and high-quality device that offers a reliable and user-friendly solution for audio professionals seeking superior control over their audio output.
