Williams AV IR ME1 – IR+ Combo Single-Emitter Infrared System

Product Overview

The Williams AV IR ME1 is a complete single-zone infrared assistive listening system for commercial venues pursuing ADA compliance. The IR+ Combo package pairs the IR M1 infrared modulator and Wi-Fi server with one IR E4 infrared emitter and an IDP 008 ADA wall plaque. The emitter covers up to 18,000 square feet in single-channel mode, making the system a practical fit for auditoriums, sanctuaries, council chambers, and large training rooms. Infrared transmission keeps audio inside the room, which also suits venues with audio confidentiality requirements.

Product Description

The system centers on the IR M1 control center, a single rack unit modulator that installs in a standard equipment rack or can be located remotely near the emitter. Two combination XLR/1/4-inch TRS inputs accept balanced or unbalanced line-level feeds from a mixer or DSP, or microphone-level sources with selectable phantom power. Onboard DSP processing offers selectable compression ratios and high-pass/low-pass filtering to maximize speech intelligibility, while a 400 Hz internal test tone, an IR test LED, and dual front-panel headphone jacks make commissioning and verification straightforward for the installing technician.

The included IR E4 emitter mounts on a wall or ceiling and connects to the modulator over a single CAT5e cable that carries 48 VDC power, RS-485 communication, and the baseband infrared signal — no electrical outlet is needed at the emitter position. The IR M1 also streams audio over Wi-Fi: connected to a multicast-capable network, it serves the program feed to the free Williams AV WaveCAST app on listeners' iOS and Android devices. Configuration, including the adjustable auto carrier shut-off, is handled through an embedded web interface. The modulator supports up to four emitters directly, so coverage can grow by adding the Williams AV IR E4 IR+ Emitter.

Frequently Asked Questions

How do I integrate the IR ME1 with my existing audio system?

Connect a line-level feed from your mixer or DSP to one of the IR M1's combination XLR/1/4-inch TRS inputs. The inputs also accept microphone-level sources with selectable phantom power if no house system exists.

Will one emitter cover my room?

The IR E4 covers up to 18,000 square feet in single-channel mode with clear line of sight. Balconies, wings, or structural obstructions may call for additional emitters, which connect to the modulator's three spare RJ-45 ports over CAT5e.

Does the IR ME1 support Dante?

Dante is available on the IR ME1 D variant, which includes the Dante-equipped IR M1 D modulator with a two-channel network audio input. The standard IR ME1 uses analog inputs.

What do listeners use to hear the audio?

Listeners use Williams AV infrared receivers tuned to the system's carrier frequencies, or stream over Wi-Fi to the free WaveCAST app on iOS and Android when the modulator is connected to a multicast-capable network.

How is the system maintained after installation?

The embedded web interface manages all settings remotely, and the auto carrier shut-off timer powers down the IR carrier when no audio is present, extending emitter life in venues with intermittent use.

What warranty comes with the system?

The modulator and emitter carry a 2-year Williams AV warranty; included accessories are covered for 90 days.
