This sound system for conference rooms is the premium solution for speech reproduction and intelligibility that provides 360° of smooth, even audio coverage. This conference sound system includes the SD5 SuperDispersion® omnidirectional drop tile ceiling speaker array and a high-performance 120W Bluetooth mixer amplifier to cover up to 2,500 square feet with crystal clear sound and impeccable speech reproduction. Wirelessly stream audio with your Bluetooth-enabled device or connect your existing audio-video equipment and conferencing hardware or personal audio device via the mixer amplifier. This audio system for conference rooms is perfect for meeting spaces, boardrooms, conference venues, meeting halls and venues, or any other conference spaces where vocal intelligibility is needed.

Use a smartphone, tablet, laptop or Bluetooth enabled PC to easily stream audio wirelessly to the system from anywhere in the room. Simply press the Mode button on the RMA120BT or remote control until the display indicates "BT", then go to settings in your device and select "PRA-BT" to pair. Once connected you're ready to play and control audio from your Bluetooth device.

The Pure Resonance Audio SD5 SuperDispersion® omnidirectional drop tile ceiling speaker array is the premium solution for speech reproduction and intelligibility that maximizes audio coverage. The SD5 drop ceiling speaker provides an industry-leading 50' by 50' of audio coverage in a smooth, even 360-degree coverage pattern and reproduces speech better than any ceiling speaker on the market today. Just one SD5 speaker takes the place of multiple traditional single ceiling speakers, saving money, simplifying and reducing installation time and cost, and optimizing performance.

The simple to operate Pure Resonance Audio RMA120BT 5-channel commercial rack mount mixer amplifier features 120 watts of high-performance power encased in a slim and lightweight space-saving design. This mixer amplifier provides quick and easy Bluetooth connection as well as the ability to accommodate most input sources like microphones, AV equipment, or computer audio. Adjust the audio levels/settings as well as control the volume of the SD5 speakers with the included remote control.
 

Due to the possibilities of FM radio interference and the variables involved, it's not recommended to use FM radio as your primary input source.

Designed to install much quicker than a traditional ceiling speaker, the SD5 is built to save your most important currency, time. Simply remove one 2'x2' (or a cut 2'x4') ceiling tile, drop the SD5 into any standard drop-ceiling grid, and attach the speaker wire and safety cables. Detailed directions can be found in the provided manuals. Pay careful attention when pulling the speaker wire and hooking up the safety cables. No special audio skills are required. After the speakers and mixer amplifier are properly installed, connect your required input sources or pair a Bluetooth-enabled device, and adjust the volume to the desired level. Enjoy!

In the event of an emergency, the RMA120BTs' emergency input (EMC In) can be configured to stop all other audio automatically. The emergency input takes priority over all other audio allowing an integrated emergency voice alarm system to be heard loud and clear. This input will work with an existing paging system, emergency paging mic, and, most importantly, a relay closure from a fire alarm system.
