IR+ Flex

IR Systems

IR ME2

The IR+ Flex is a ready-to-install infrared assistive listening package that delivers audio over both infrared and Wi-Fi. The system includes the IR M1 IR+ Control Center, two IR E4 emitters, an MLB 003 linking bar, and an IDP 008 ADA accessibility sign, giving venues the flexibility to cover larger or more complex rooms from day one.

Infrared is best used for assistive audio in large spaces, or for secured audio transmission within a room. Connect the IR M1 to a Wi-Fi multicast router or in-house network to stream audio over Wi-Fi to the Williams AV WaveCAST® app (available in the iOS app store or Google Play store), so guests can also listen on their own smartphones.

Each IR E4 emitter connects to the IR M1 with a single CAT5e cable that carries power, audio, and control, and covers up to 18,000 sq. ft. in single channel mode. The two emitters can be linked together for a larger room array or distributed throughout the room to cover wings, balconies, or other obscured venue locations. As needs grow, the IR M1 supports up to four emitters directly, or up to 16 with IR A4 emitter arrays.

The rack-mountable IR M1 accepts audio through two combination XLR/1/4″ (TRS) inputs for line or microphone level sources, with selectable phantom power. Audio processing, compression, filters, and the auto carrier shut-off timer are adjusted through the IR M1’s embedded website, and front-panel headphone jacks and a built-in test tone simplify setup.

The IR+ Flex is ideal for courtrooms, boardrooms, lecture halls, houses of worship, theaters, and other venues that need reliable, secure assistive listening across larger or irregularly shaped spaces.

Receivers are sold separately.

  1. What is the IR+ Flex? The IR+ Flex is a ready-to-install infrared assistive listening package that delivers audio over both infrared and Wi-Fi. It pairs the IR M1 IR+ Control Center with two IR E4 emitters and ADA signage for larger or more complex rooms.
  2. What is included in the IR+ Flex? The system includes:
    • IR M1 infrared modulator
    • (2) IR E4 emitters
    • MLB 003 linking bar
    • IDP 008 accessibility sign

    Receivers are sold separately.

  3. How is the IR+ Flex different from the IR+ Combo? The IR+ Combo includes one IR E4 emitter for single-room coverage. The IR+ Flex includes two IR E4 emitters and a linking bar, giving venues more flexibility to build a larger room array or place emitters in different areas of the room.
  4. How large an area does each emitter cover? Each IR E4 emitter covers up to 18,000 sq. ft. in single channel mode.
  5. How can the two emitters be positioned? The emitters can be linked together for a larger room array or distributed throughout the room to cover wings, balconies, or other obscured areas of a venue.
  6. Can I add more emitters later? Yes. The IR M1 supports up to four IR E4 emitters directly, or up to 16 when using IR A4 emitter arrays, so coverage can grow as venue needs expand.
  7. 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.
  8. 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.
  9. 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.
  10. 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.
  11. What audio inputs does the system 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.
  12. Does the system help meet ADA assistive listening requirements? The IR+ Flex includes ADA signage to help venues promote assistive listening in their location. ADA compliance depends on the number of receivers provided, system design, installation, and venue-specific requirements.
  13. How is the system configured? Settings such as audio processing (compression and high-pass/low-pass filters) and the auto carrier shut-off timer can be adjusted through the IR M1’s embedded website. Two front-panel headphone jacks allow monitoring of the CH A and CH B audio inputs, and a built-in 400 Hz test tone helps with setup and diagnostics.
  14. Can the IR M1 be rack mounted? Yes. The IR M1 occupies a single rack unit and can be rack mounted or located remotely.
  15. What is the warranty? 5 years on parts and labor with product registration; 2 years standard without registration. Accessories for 90 days, regardless of registration.
