How It Works

The SoundPlus IR T3 commercial-grade, medium-area infrared transmitter can cover up to 32,000 sq. ft. in single-channel mode with the RX22-4 receiver. Its sleek, compact footprint is ideal for assistive listening and language interpretation in commercial spaces such as conference rooms, assisted living facilities, small cinema/theaters, classrooms and courtrooms. The IR T3 is capable of transmitting on four different carrier frequencies in single-channel mode, but it can only transmit on two channels simultaneously. It can be set to transmit on 2.3 and 2.8 MHz simultaneously, or it can be set to transmit on 3.3 and 3.8 MHz simultaneously. The unit automatically detects the presence of audio on the microphone and Phoenix style audio inputs and transmits on either or both channels when an audio signal is present. The IR T3 is shipped with Williams Sound's TFP 057 (48VDC power supply). It also includes optional Power-over-Ethernet (PoE) capability, allowing remote power delivery up to 100 feet, and remote RS-232 commands provide convenient control. Furthermore, IR T3 is also compatible with the Williams Sound POE 001 Power-over-Ethernet transformer, and with most POE switches (see Tech data IR T3 POE Kits).

The IR RX22-4N is a four-channel selectable infrared receiver compatible with transmitters operating on the 2.3/2.8/3.3/3.8 MHz bandwidth. Comfortable, body-pack design features convenient channel selector and easy-to-use on/off volume control. The RX22-4N can be used with mono or stereo headphones, earphones or a neckloop (lanyard included). Dual infrared detectors maximize sensitivity and operating range.

The optional CHG 3502 and CHG 3512 multi-unit, drop-in style chargers will conveniently store and charge 2 to 12 WIR RX22-4N infrared receivers over the course of a 16-hour time span. The chargers help keep receivers organized and save costs on having to replace alkaline batteries. The chargers feature individual charging LED indicators that blink when batteries are ready. The CHG 3512 drop-in charger is also available in a Pro version where it is built into a convenient storage/carry case.

The IR RX20 is a comfortable, stereo stethoscope-shaped infrared receiver. The headset works with all Williams Sound 2.3 or 2.8 MHz infrared systems. A 3-position selection switch is used to choose from 2.3 MHz, 2.8 MHz, or stereo mode. Rotating the volume control will adjust the volume to a comfortable listening level. The RX20 receiver can be connected to a neckloop for use with a T-Coil enabled hearing aid, making it ADA compliant.

The IR RX20 receiver has an internal LiPo battery which should be charged when not in use. The CHG 520 multi-unit, drop-in style charger will conveniently charge and store up to 5 IR RX20 under-the-chin style infrared receivers. A 15-Bay Charger Pack CHG 1520 is also available. This bundle includes 3 CHG 520 5-Bay chargers that can be connected via jumper cables so that all chargers work from only one power supply. These 6-hour smart chargers help keep your products organized and batteries consistently charged.
