Product Overview The Yamaha ADECIA Ceiling Mic and Line Array Speaker System is a complete, purpose-built conference audio solution combining the RM-CG ceiling array microphone, VXL1-16P line array speaker, and RM-CR remote conference processor in a single bundle. Designed for professional conference rooms, boardrooms, and collaboration spaces, the system delivers beamforming microphone coverage, full-range reinforced audio, and integrated signal processing over a single Cat 5e+ network connection using Dante and PoE. All components are designed to work together with minimal configuration, making the ADECIA ceiling bundle a practical choice for AV integrators and IT/facilities teams deploying unified communications rooms. The system is available in white (RM-CG-W) and black (RM-CG-B) to suit ceiling aesthetic requirements. Product Description The RM-CG ceiling array microphone is the capture element of the ADECIA system. Mounted directly to the ceiling, it uses Multi Beam Tracking technology to automatically follow active talkers anywhere in the room without manual intervention or operator adjustment. The microphone integrates acoustic echo cancellation (AEC), noise reduction, dereverberation, and auto-mixer functions into a single unit, keeping signal processing consolidated at the microphone rather than distributed across multiple DSPs. Power and audio are delivered over a single Cat 5e+ STP cable via PoE (IEEE 802.3af), reducing installation complexity. The RM-CG supports Dante audio transport at 48kHz/24-bit with 1 audio input and 2 audio outputs per unit, and offers a low-latency mode (22ms) for applications requiring tighter sync. The unit is plenum rated (UL2043 with terminal cover) and carries IP5X dust protection, meeting the requirements for above-ceiling and commercial building installation. Up to 14 RM-CG units (or 16 without VXL1-16P) can be connected to a single RM-CR processor, supporting larger room configurations without additional hardware. The VXL1-16P line array speaker provides natural-sounding audio reinforcement for conference speech and unified communications content. The RM-CR remote conference processor acts as the system controller, managing Dante routing, signal processing parameters, and integration with UC platforms. Together, the three components form a complete ADECIA ceiling solution that integrates into Dante-based AV infrastructure and works with leading soft-codec platforms. Creation Networks supplies and supports ADECIA deployments for integrators and end users; see creationnetworks.net for system design assistance. Key Features Multi Beam Tracking Microphone — Automatically follows active talkers without manual beam adjustment, reducing operator dependency in conference environments. Integrated AEC, Noise Reduction, and Dereverberation — Built-in acoustic processing in the RM-CG microphone eliminates the need for a separate DSP for echo and noise control. Dante Audio over Cat 5e+ — Single-cable PoE and Dante audio delivery simplifies ceiling installation and reduces cabling cost. PoE Powered (IEEE 802.3af) — No separate power supply required at the ceiling; the microphone draws 7.2W max from a standard PoE switch. Plenum Rated (UL2043) — Approved for above-ceiling installation in commercial buildings when terminal cover is fitted. IP5X Dust Protection — Suitable for above-ceiling environments where dust accumulation is a concern. Low-Latency Mode (22ms) — Supports applications requiring tight audio synchronization alongside video or other real-time signals. Auto Mixer and AGC — Manages multiple simultaneous talkers and maintains consistent output levels without manual gain riding. Complete Bundle: RM-CG + VXL1-16P + RM-CR — Microphone, speaker, and processor included for a fully configured ADECIA ceiling solution in one purchase. Available in White or Black — Ceiling finish options to match room design requirements. Typical Applications Corporate boardrooms and executive conference rooms requiring discreet ceiling audio Medium and large meeting rooms in enterprise office environments Huddle rooms and collaboration spaces with unified communications platforms Government and legal conference facilities requiring full-coverage microphone pickup Education conference rooms, faculty meeting spaces, and distance learning rooms Healthcare conference and telemedicine rooms where surface-mount microphones are impractical Hotels and hospitality meeting spaces with aesthetic ceiling-flush requirements Technical Specifications Specification Detail Bundle Components RM-CG ceiling array mic + VXL1-16P line array speaker + RM-CR conference processor RM-CG Dimensions W560 × D560 × H90 mm RM-CG Weight 5.6 kg Power (RM-CG) PoE IEEE 802.3af, 7.2W max Mounting Options Ceiling, Wire, VESA Plenum Rating UL2043 (with terminal cover) Dust Protection IP5X (with terminal cover) Network Connection RJ45, Cat 5e+ STP Network Protocol Dante audio + control, PoE Dante Audio I/O 1 in / 2 out, 48kHz, 24-bit Latency 58ms standard / 22ms low-latency mode Frequency Response 160Hz – 16kHz (−10dB) Max SPL 117.8 dB Self Noise −0.8 dBA SNR 94.8 dBA Dynamic Range 118.6 dBA Signal Processing Multi Beam Tracking, AEC, Noise Reduction, Dereverberation, Auto Mixer, AGC, PEQ, Output Gain Max Devices per RM-CR 14 (or 16 without VXL1-16P) Color Options White (RM-CG-W), Black (RM-CG-B) Frequently Asked Questions Q: What is included in this bundle? A: The bundle includes the RM-CG ceiling array microphone, the VXL1-16P line array speaker, and the RM-CR remote conference processor. Together they form a complete ADECIA ceiling audio system. Q: Does the system require a separate DSP for echo cancellation? A: No. The RM-CG microphone has acoustic echo cancellation, noise reduction, dereverberation, auto mixer, and AGC processing built in. No external DSP is required for these functions. Q: How is the RM-CG powered? A: The RM-CG is powered by PoE (IEEE 802.3af) over the same Cat 5e+ STP cable that carries the Dante audio and control signal. Maximum power draw is 7.2W, compatible with standard 802.3af PoE switches. Q: Is the RM-CG approved for above-ceiling (plenum) installation? A: Yes. The RM-CG carries a UL2043 plenum rating when the terminal cover is installed, meeting commercial building code requirements for above-ceiling use. Q: How many RM-CG units can connect to one RM-CR processor? A: Up to 14 RM-CG units per RM-CR when used with VXL1-16P speakers, or up to 16 units without VXL1-16P speakers, supporting larger room or multi-zone configurations. Q: What unified communications platforms does the ADECIA system support? A: The ADECIA system integrates with leading soft-codec UC platforms. Contact Creation Networks at creationnetworks.net for specific platform compatibility guidance for your deployment. Q: Can the microphone track multiple simultaneous talkers? A: Yes. The RM-CG’s Multi Beam Tracking and auto mixer functions manage multiple simultaneous talkers, automatically directing beams and adjusting levels without operator intervention. Q: What ceiling types and mounting configurations are supported? A: The RM-CG supports direct ceiling mount, wire suspension, and VESA mount configurations, accommodating standard acoustic tile grids, concrete ceilings, and custom suspension installations.
