IR T3 architectural and engineering specifications
Architectural/Consultant Specs
The Infrared Transmitter shall consist of an all-in-one modulator and emitter operating on 2.3 MHz and/or 2.8 MHz (or 3.3 and/or 3.8 MHz). The carrier frequency shall use 50 kHz deviation and 50 µS pre-emphasis. The transmitter will operate in 2-channel mode on 2.3 and 2.8 or on 3.3 and 3.8 MHz. The transmitter will operate in single-channel mode on 2.3, 2.8, 3.3, or 3.8 MHz. The transmitter shall have coverage up to 32,000 ft
2 (2,972 m
2) with the WIR RX22-4 infrared receiver in single-channel mode or 19,000 ft
2. (1,765 m
2) with the RX20 infrared receiver in single
-channel mode. The transmitter shall be housed in a heavy-duty black plastic enclosure with a metal plate base and a durable infrared transparent front lens. It shall be convection-cooled without fans and have a sleep/power save mode that shuts off the IR when no audio is present for 12 minutes.The Transmitter shall have a signal-to-noise ratio of 70 dB or better and have an audio frequency response of 95 Hz to 17.6Hz, -3 dB re 1 kHz (line inputs), and 125 Hz to 17.0 kHz, -3 dB re 1 kHz (microphone input). The Transmitter includes an omnidirectional mounting bracket for various permanent installations. Each channel shall have a line-level Phoenix-style connector input, and each channel shall have an audio input-level LED.There shall be a single 3.5 mm microphone input with gain control, and the mic input shall have a channel selector switch. The transmitter shall have a switch to turn off all indicator LEDs if pressed and held and change the carrier frequency set if pressed and held. The transmitter shall be powered by a 48 VDC universal power supply, 50-60 Hz, 100-240 VAC input, 18 W with optional Power over Ethernet (PoE) support. The transmitter shall have RS-232 monitoring and control available for third-party controllers.The transmitter shall be covered by a two-year parts and labor warranty and 90 days on accessories. The Williams AV SoundPlus T3
® infrared transmitter is specified.

Infrared audio is ideal for assistive listening for ADA/Disability compliance, language interpretation, and audio description in environments requiring privacy and confidentiality or where audio signals must remain in a space without spillover to adjacent spaces. Frequently used in:
- Medical centers and treatment rooms
- Courtrooms, jury deliberation rooms, and city council chambers
- Classrooms and lecture halls
- Auditoriums and theaters
- Conference rooms, corporate boardrooms, and training centers
