Crestron Collab DM NAX Intelligent Audio Certified System — Large Room Ceiling System

What is the Crestron DM NAX Intelligent Audio Certified System — Large Room?

The Crestron DM NAX Intelligent Audio Certified System for large rooms is a pre-validated ceiling audio kit for large conference rooms and training spaces, built around Crestron's DM NAX audio-over-IP platform and certified for use with Microsoft Teams software. It pairs one DM-NAX-AP-100 audio processor, one active Saros PoE ceiling speaker driving three passive Saros speakers, and two Sennheiser TeamConnect Ceiling Medium microphones into a validated PoE audio system that any AV integrator can deploy without custom DSP programming. It's the top tier in Crestron's certified system lineup, scaling up from the Small Room and Medium Room configurations.

How does the Crestron DM NAX Intelligent Audio Certified System — Large Room work?

Every device connects over standard Power over Ethernet and auto-discovers on the network the moment it's plugged in, eliminating the custom wiring and DSP commissioning that ceiling audio installs in large rooms typically require. The DM-NAX-AP-100 audio processor bridges the full ceiling audio system to any UC codec over USB-C, while dual Gigabit Ethernet ports handle network audio distribution and onboard DSP automatically manages echo cancellation and noise reduction across the room.

This configuration uses the active Saros DM-NAX-IC4A-W at full capacity — its onboard amplifier drives all three passive Saros IC4P-W speakers it supports, delivering even program audio across a much larger floor plan from a single amplified, PoE-powered source. To match that footprint on the microphone side, two Sennheiser TeamConnect Ceiling Medium arrays cover the room instead of one, each using automatic beam steering to track whoever is speaking within its zone and feeding clean audio into the DM NAX network over AES67. The result is full-room voice pickup and even audio coverage in spaces too large for a single microphone or speaker to handle well, while staying compatible with AI meeting assistants such as Microsoft 365 Copilot.

What are the key features of the Crestron DM NAX Intelligent Audio Certified System — Large Room?

• Full active/passive speaker array — one amplified Saros speaker drives three passive satellites for even large-room coverage.
• Dual ceiling microphones — two Sennheiser TCC M arrays split coverage across a longer or wider room than a single mic can serve well.
• PoE-powered, zero-wiring deployment — every powered device runs on standard PoE, with no dedicated audio wiring or amplifier rack.
• Automatic device discovery — the processor, speakers, and microphones find each other on the network without manual addressing.
• Certified for Microsoft Teams — validated end-to-end for functionality, integration, and performance with Teams Rooms deployments.
• AES67-compatible audio-over-IP — built on an open standard for future peripheral flexibility.
• Onboard DSP echo and noise cancellation — no external DSP rack unit needed for clean call audio at scale.

Where is the Crestron DM NAX Intelligent Audio Certified System — Large Room typically used?

• Large conference rooms
• Training rooms
• Boardrooms
• All-hands rooms
• Multi-purpose rooms

Frequently Asked Questions

Why does this configuration use two microphones instead of one?

Large conference rooms and training spaces exceed the reliable pickup range of a single ceiling microphone array. Two Sennheiser TeamConnect Ceiling Medium units split coverage across the room so speaker tracking stays accurate at both ends.

Do the three passive speakers need their own amplifiers?

No. All three passive Saros IC4P-W speakers are powered and driven directly by the single active Saros DM-NAX-IC4A-W unit, which is rated to support up to three passive speakers from its onboard amplifier.

What UC platforms is this certified for?

This configuration is certified for use with Microsoft Teams software. Ask your Creation Networks rep about certification status for other UC platforms.

How does this compare to the Medium Room system?

The Medium Room system uses one active and one passive speaker with a single microphone; this Large Room configuration uses the same active speaker's full three-passive capacity and doubles the microphone count for a bigger room footprint.

Does this pair with Crestron's Collab Compute room systems?

Yes. This is an audio-only ceiling system that connects to any UC codec over USB-C, including Crestron's Collab Compute modules used in our full room bundles — including our own Large Conference Room camera-and-compute bundle. See our full Crestron collection for more.

Does Creation Networks install this system?

Yes. As a nationwide AV integrator, Creation Networks provides design, installation, and commissioning services alongside the equipment — contact us at 888-230-3661 or sales@creationnetworks.net for a project quote.
