IR+ Control Center

Large-Area Solutions, IR Transmitters & Emitters

IR M1

The IR+ Control Center offers a versatile dual audio solution, allowing venues to opt between audio transmission via Wi-Fi or Infrared.  Its design includes a scalable distributed infrared emitter array architecture, enabling the utilization of up to four emitters. These emitters can be stacked for extensive room arrays or strategically distributed throughout the space to cater to various room layouts, including wings, balconies, or other concealed areas within the venue.

The IR+ Control Center offers both Wi-Fi and Infrared audio transmission options, with Infrared being particularly suitable for assistive audio in spacious environments or for secure transmission within enclosed spaces. By connecting the IR M1 to a Wi-Fi multicast router or an in-house network, users can stream audio over Wi-Fi to the Williams AV WaveCAST app (available in the iOS app store or Google Play store).

Featuring a distributed infrared emitter array architecture, the IR+ Control Center accommodates up to four emitters, which can be either stacked for large room arrays or strategically distributed throughout the venue to accommodate various room layouts, including wings, balconies, or other obscured locations.

The rack-mounted or remotely located IR M1 Control Center includes support for up to four IR emitters as standard. Each emitter connects back to the modulator via a CAT5e cable, delivering both audio and power necessary to operate the remote emitter. With each emitter covering an area of 18,000 sq. ft., ample coverage is ensured throughout the designated space.

*Note: Firmware is model specific. Firmware updates are currently unable to be completed on Mac computers.

Tech Tutorial | Setting Up the IR M1 WEB UI

  1. What is the IR+ Control Center? The IR M1 IR+ Control Center is an infrared modulator that delivers audio over both infrared and Wi-Fi. Infrared is ideal for assistive listening in large spaces or for secure audio transmission within a room, while Wi-Fi streaming lets guests listen on their own smartphones through the free Williams AV WaveCAST® app.
  2. How many emitters can the IR M1 support? The IR M1 has four RJ-45 emitter outputs and supports up to four IR E4 emitters directly, or up to 16 when using IR A4 emitter arrays. Emitters can be stacked together for large room arrays or distributed throughout the room to cover wings, balconies, or other obscured areas of a venue.
  3. How large an area can the system cover? Each IR E4 emitter covers up to 18,000 sq. ft. in single channel mode, so coverage scales with the number of emitters connected.
  4. How are the emitters connected and powered? Each emitter connects to the IR M1 with a single CAT5e cable that carries power (+48VDC), RS-485 communication, and the baseband signal for IR transmission, so no separate power supply is needed at the emitter location.
  5. Why choose infrared for assistive listening? Infrared light stays within the room, which makes it well suited for secure or confidential audio, such as courtrooms, boardrooms, and government facilities, and allows multiple rooms in the same building to operate without interference.
  6. Can guests listen on their smartphones? Yes. Connect the IR M1 to a Wi-Fi multicast router or in-house network to stream audio over Wi-Fi to the free WaveCAST® app, available in the iOS App Store and Google Play store.
  7. What carrier frequencies does the IR M1 use? The IR M1 carrier frequency is selectable between 2.3/2.8 MHz and 3.3/3.8 MHz. When choosing receivers, make sure they support the carrier setting used on the IR M1.
  8. What audio inputs does the IR M1 have? The IR M1 has two combination 3-pin XLR/1/4″ (TRS) jacks that accept balanced or unbalanced line level or microphone signals, with selectable phantom power.
  9. What audio processing does the IR M1 offer? The IR M1 has DSP-based audio processing with selectable compression (1:1, 1.5:1, or 2:1) and adjustable high-pass and low-pass filters. Settings are adjusted through the IR M1’s embedded website.
  10. Does the IR M1 turn off automatically? Yes. An adjustable auto carrier shut-off timer turns off the carrier when no audio is present. The timer is set through the embedded website.
  11. What tools are available for setup and monitoring? Two front-panel 1/4″ headphone jacks allow monitoring of the CH A and CH B audio inputs, and a built-in 400 Hz test tone can be selected as an audio source for setup and diagnostics. The IR M1 can also be configured remotely through its embedded website.
  12. Can the IR M1 be rack mounted? Yes. The IR M1 occupies a single rack unit and can be rack mounted or located remotely.
  13. What is the audio quality of the IR M1? The IR M1 has a frequency response of 40 to 16,000 Hz, a typical signal-to-noise ratio of 67 dB, and total harmonic distortion of less than 2%.
  14. Can firmware be updated from a Mac? Not currently. Firmware updates are unable to be completed on Mac computers at this time. Firmware is model-specific, so be sure to download the firmware for the IR M1.
  15. What is the warranty? The IR M1 is covered for 5 years on parts and labor with product registration, or 2 years standard without registration. Accessories are covered for 90 days, regardless of registration.
