Product Overview

The Williams AV IR SY1 is a single-listener, small-area infrared assistive listening system built for private TV listening and hearing assistance in small conference rooms, hospital rooms, assisted living facilities, medical treatment centers, and jury deliberation rooms. The kit pairs the IR T1 two-channel infrared transmitter with one WIR RX22-4N four-channel bodypack receiver, folding headphones, and a flat-panel TV mounting bracket, covering up to 1,300 square feet. Setup is plug-and-play, and because infrared audio cannot leave the room, the system preserves privacy in sensitive environments.

Product Description

The IR T1 transmitter combines the infrared modulator and emitter in one compact, mountable enclosure, reducing operating costs and eliminating the need for rack space. Connect any line-level stereo source to the 3.5mm input jack the included WCA 124 adapter cable handles TVs with RCA stereo outputs and the carriers enable automatically when audio is present. Power comes from the included TFP 055 power supply or directly from a TV’s USB port via the included WCA 106 micro-USB cable, which keeps cabling minimal in patient rooms and resident apartments. Operating frequencies of 2.3 and 2.8 MHz minimize interference from high-efficiency lighting, and the channel automatically enters a power-save mode after 12 minutes without audio, cutting power consumption by 80 percent.

The included STD 008 flat-panel TV top shelf mounts the transmitter on a display without drilling, and the IR T1 also accepts any camera tripod with a 1/4″-20 thread. The WIR RX22-4N bodypack receiver offers four selectable channels, dual infrared detectors for strong sensitivity throughout the coverage area, and on/off/volume controls, running up to 60 hours on the included AA alkaline batteries. The HED 021 folding mono headphones provide comfortable, lightweight listening. No FCC license is required, and adjacent rooms can run identical systems without crosstalk.

Frequently Asked Questions

What comes in the IR SY1 kit?

The kit includes the IR T1 small-area infrared transmitter, TFP 055 power supply, WCA 106 6-foot micro-USB cable, a WIR RX22-4N infrared receiver, an STD 008 flat-panel TV mounting bracket, HED 021 folding headphones, and BAT 001-2 AA alkaline batteries.

How do I connect the IR SY1 to a TV?

Connect the TV’s audio output to the IR T1’s 3.5mm stereo line input; the included adapter cable supports TVs with RCA stereo outputs. The transmitter can be powered from the TV’s own USB port using the included micro-USB cable, so a wall outlet is optional.

Will the audio disturb other rooms or patients?

No. The listener hears TV audio privately through the headphones, and the infrared signal cannot pass through walls, making the system well suited to hospital rooms, resident apartments, and jury rooms.

Can I add a second listener later?

Yes. The IR T1 supports additional compatible receivers such as the WIR RX22-4N or IR RX20 within its coverage area simply purchase another receiver and headphones.

Does the system require an FCC license?

No. Infrared systems use light rather than RF spectrum, so no FCC license or radio approval is required and the system can be used anywhere in the world.

What warranty covers the transmitter?

The IR T1 transmitter carries a 2-year Williams AV manufacturer warranty.
