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 \u003ca href=\"\/products\/crestron-collab-dm-nax-intelligent-audio-certified-system-small-room-ceiling-system\"\u003eSmall Room\u003c\/a\u003e and \u003ca href=\"\/products\/crestron-collab-dm-nax-intelligent-audio-certified-system-medium-room-ceiling-system\"\u003eMedium Room\u003c\/a\u003e configurations.\u003c\/p\u003e\u003ch2\u003eHow does the Crestron DM NAX Intelligent Audio Certified System — Large Room work?\u003c\/h2\u003e\u003cp\u003eEvery 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.

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.\u003c\/p\u003e\u003ch2\u003eWhat are the key features of the Crestron DM NAX Intelligent Audio Certified System — Large Room?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull active\/passive speaker array\u003c\/strong\u003e — one amplified Saros speaker drives three passive satellites for even large-room coverage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual ceiling microphones\u003c\/strong\u003e — two Sennheiser TCC M arrays split coverage across a longer or wider room than a single mic can serve well.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoE-powered, zero-wiring deployment\u003c\/strong\u003e — every powered device runs on standard PoE, with no dedicated audio wiring or amplifier rack.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic device discovery\u003c\/strong\u003e — the processor, speakers, and microphones find each other on the network without manual addressing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertified for Microsoft Teams\u003c\/strong\u003e — validated end-to-end for functionality, integration, and performance with Teams Rooms deployments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAES67-compatible audio-over-IP\u003c\/strong\u003e — built on an open standard for future peripheral flexibility.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOnboard DSP echo and noise cancellation\u003c\/strong\u003e — no external DSP rack unit needed for clean call audio at scale.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere is the Crestron DM NAX Intelligent Audio Certified System — Large Room typically used?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLarge conference rooms\u003c\/li\u003e\n\u003cli\u003eTraining rooms\u003c\/li\u003e\n\u003cli\u003eBoardrooms\u003c\/li\u003e\n\u003cli\u003eAll-hands rooms\u003c\/li\u003e\n\u003cli\u003eMulti-purpose rooms\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable style=\"table-layout:fixed;min-width:300px;width:100%;\"\u003e\n\u003ccolgroup\u003e\n\u003ccol style=\"width:45%\"\u003e\n\u003ccol style=\"width:55%\"\u003e\n\u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAudio Processor\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDM-NAX-AP-100 — USB-C to UC codec, dual Gigabit Ethernet, onboard DSP, PoE+ (12.95W)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eActive Ceiling Speaker\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1x Saros DM-NAX-IC4A-W — 4 in. active full-range driver, onboard amplifier, PoE+ (25.5W)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePassive Ceiling Speakers\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3x Saros IC4P-W — powered directly from the active Saros unit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCeiling Microphones\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2x Sennheiser TeamConnect Ceiling Medium — automatic beam steering, PoE+ powered, flush ceiling-tile mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAudio Network\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDM NAX audio-over-IP, AES67-compatible\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCertification\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCertified for use with Microsoft Teams software\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eWhy does this configuration use two microphones instead of one?\u003c\/h3\u003e\u003cp\u003eLarge conference rooms and training spaces exceed the reliable pickup range of a single ceiling microphone array.
