Williams AV IR SY11 D – IR+ Complete Infrared System with Dante

Product Overview

The Williams AV IR SY11 D is the IR+ Complete system with Dante, a fully equipped large-area infrared assistive listening package built around the IR M1 D modulator. Two linked IR E4 emitters, four four-channel WIR RX22-4 bodypack receivers, headphones, neckloops, chargers, and ADA signage ship together, so an AV integrator can deliver compliant hearing assistance for an auditorium or worship space from a single part number. The Dante input drops the system onto an existing networked audio backbone with no analog tie lines.

Product Description

At the rack, the IR M1 D infrared modulator occupies one rack unit and accepts two channels of program audio over Dante or through two combination XLR/quarter-inch TRS inputs handling balanced or unbalanced line-level or microphone sources with selectable phantom power. DSP-based processing applies compression at 1:1, 1.5:1, or 2:1 and high-pass/low-pass filtering tuned for speech intelligibility, and the embedded web page manages all settings remotely, including carrier selection between the 2.3/2.8 and 3.3/3.8 MHz pairs and the adjustable auto carrier shut-off timer.

The two IR E4 emitters mount as a pair on the included MLB 003 linking bar with BKT 024 wall brackets. Each connects to the modulator over one Cat5e cable carrying +48 VDC power, RS-485 communication, and the baseband infrared signal, which keeps installation to a pair of structured cabling runs. Rated at up to 18,000 square feet per emitter in single-channel mode, the linked pair covers large sanctuaries, lecture halls, and council chambers, and the modulator's four RJ-45 ports leave headroom to add emitters if coverage requirements grow. Infrared stays inside the room, so multi-room facilities avoid cross-talk entirely.

The receiver package is what earns the Complete name. Four WIR RX22-4 four-channel bodypack receivers ship with lanyards, four HED 021 performance headphones, two NKL 001 neckloops for telecoil hearing aid users, four pairs of rechargeable AA batteries, and two CHG 3502 two-bay drop-in chargers. The IDP 008 plaque signals assistive listening availability for ADA compliance. For a complete picture of receivers, chargers, and signage, see the Williams AV collection at Creation Networks; if your venue requires room-secure operation with stethoset receivers, compare the IR SY12 D IR+ Secure with Dante.

Key Features

• Complete Out-of-Box System — Modulator, dual emitters, four receivers, headphones, neckloops, rechargeable batteries, chargers, mounting hardware, and ADA signage arrive in one package ready for installation.
• Dante Audio Networking — The IR M1 D takes two channels directly from the Dante network, integrating with networked DSPs and consoles common in modern commercial AV systems.
• Large-Area Linked Emitters — Two IR E4 emitters on the MLB 003 bar each cover up to 18,000 square feet in single-channel mode, with two spare modulator ports for future expansion.
• Four-Channel Bodypack Receivers — WIR RX22-4 receivers select among 2.3, 2.8, 3.3, and 3.8 MHz carriers and run up to 60 hours on alkaline AA cells.
• Hearing Aid Support Included — Two NKL 001 neckloops couple receiver audio to telecoil hearing aids for ADA hearing-aid-compatible counts.
• Cat5e Emitter Cabling — One cable per emitter carries power, control, and signal, eliminating emitter-side power supplies.
• DSP Speech Processing — Selectable compression and filtering condition audio for hearing assistance.
• Remote Web Management — Configuration, diagnostics, and the 400 Hz test tone are accessible through the modulator's embedded web page.

Typical Applications

• House of worship

Frequently Asked Questions

What distinguishes IR+ Complete from IR+ Secure?

Both packages share the IR M1 D modulator and dual IR E4 emitters. The Complete (SY11 D) ships with four-channel WIR RX22-4 bodypack receivers, headphones, and neckloops, while the Secure (SY12 D) ships with five rechargeable IR RX20 stethoset receivers and a five-bay charger. Choose based on receiver preference and handout workflow.

How does Dante integration work in practice?

The IR M1 D appears as a Dante device on the network; route two channels to it from any Dante-enabled DSP or console in Dante Controller. The analog combo inputs remain available for local or backup sources.

Can I run two languages or programs simultaneously?

Yes. The modulator carries two audio channels on separate carriers, and the WIR RX22-4 receivers select among four channels, so listeners pick their program at the bodypack.

Is the receiver battery system rechargeable?

The package includes four pairs of rechargeable AA batteries and two CHG 3502 drop-in chargers. Receivers also run on standard alkaline AAs for up to 60 hours when charging infrastructure is unavailable.

What does ADA compliance require beyond the hardware?

Venues must provide receiver counts scaled to seating capacity, a portion hearing-aid compatible via neckloop, and post signage such as the included IDP 008 plaque. Verify counts against the ADA assistive listening tables for your occupancy.

What warranty and support apply?

Williams AV warrants the modulator and emitters for 2 years and the receivers for 5 years, with 90-day coverage on accessories. Creation Networks supplies replacement receivers, batteries, and accessories over the system's life.
