System Includes
(1) IR T2 infrared transmitter
(1) BKT 024 wall / ceiling mounting bracket
(1) TFP 057 international power supply with line cord
How It Works
The IR T2 can be controlled remotely via RS-232 commands. The commands include:
- Powering the unit on/off
- Remotely setting the IR frequency (2.3/2.8 or 3.3/3.8)
- Muting the outgoing audio without powering off
- Turning back panel LEDs on or off
- Troubleshooting abilities
A full list of commands is available on the downloads tab in the IR T2 Programmer’s Guide.
IR T2 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 18,000 ft2 (1,672 m2) with the WIR RX22-4 receiver in single-channel mode or 11,500 ft2. (1,068 m2) with the RX20 receiver in dual-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 five-year parts and labor warranty and 90 days on accessories. The Williams AV SoundPlus Infrared IR-T2 is specified.
