About the System Components

Pure Resonance Audio SD5 SuperDispersion Drop Ceiling Speaker Array

The SD5 SuperDispersion® drop ceiling speaker array serves as the acoustic foundation of this system. Engineered with multiple custom drivers arranged for wide, even dispersion, it delivers true 360° x 180° coverage, filling the room with balanced, intelligible sound. By minimizing frequency cancellation and hot spots, the SD5 ensures that every participant hears clearly—no matter where they are seated. Its low-profile drop-ceiling design integrates seamlessly into standard ceiling grids, preserving a clean, professional aesthetic.

Pure Resonance Audio RMA240BT Rack Mount Bluetooth Mixer Amplifier

The RMA240BT provides 240 watts of reliable, high-efficiency power to drive the SD5 array with clarity and headroom. Built for commercial environments, this rack-mount mixer amplifier features Bluetooth streaming for quick wireless audio playback from laptops, tablets, and smartphones. Multiple mic and line inputs, independent level controls, tone adjustment, and emergency override capability make it a versatile control hub for presentations, background audio, and priority announcements.

Shure SLXD124+/85M Handheld and Lavalier Wireless Microphone System

The SLXD124+/85M digital wireless combo system includes the SLXD2+ handheld transmitter with industry-standard SM58 capsule and the SLXD1+ bodypack paired with a WL185M cardioid lavalier microphone. Delivering 24-bit digital audio with >118 dB dynamic range, this system provides exceptional vocal clarity and RF stability. ShowLink® and Wireless Workbench® compatibility allow remote monitoring and management, while handheld and hands-free options give presenters maximum flexibility.

Shure Microflex MXCW640 Wireless Conference Units

The twelve MXCW640 wireless conference units enable seamless participant interaction, including speaking, voting, and discussion management. Each unit operates on secure digital wireless technology and includes SB930 rechargeable batteries for long-lasting operation. With cable-free deployment, rooms can be quickly reconfigured to accommodate board meetings, training sessions, or collaborative workshops without infrastructure limitations.

Shure MXC416/C 16" Single Bend Cardioid Gooseneck Conference Microphones

Each MXCW640 unit is paired with a Shure MXC416/C 16-inch single-bend cardioid gooseneck microphone for precise voice capture. The cardioid pickup pattern reduces background noise and enhances speech clarity, while the flexible gooseneck allows comfortable positioning for every participant. This ensures consistent intelligibility across the entire conference system.

Shure MXCWAPT Access Point Transceiver

The MXCWAPT access point transceiver coordinates all wireless conference units and manages RF performance throughout the room. It automatically selects clean frequencies, maintains low-latency communication, and provides encrypted audio transmission for secure meetings. With centralized monitoring and control, the MXCWAPT ensures reliable, interference-free operation across the entire system.
