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 4-16Ω/70V rack mount mixer amplifier is lightweight, space-saving, and has the power to handle a variety of applications. With the RMA’s forced air-cooling fan and PTT1’s durable gooseneck mic and metal table-stand, this office paging system is ready to work overtime. The Pure Resonance Audio PTT1 desktop push-to-talk microphone provides excellent performance and reliability, ideal for paging and announcements in waiting areas, offices, small businesses, workspaces, and commercial facilities.

When making a page or announcement for your employees with this push-to-talk microphone system or in the case of an emergency, you won't need to worry about turning off your audio or adjusting inputs or volume. The mixer amplifier includes priority and emergency inputs that will lower the volume or completely stop all other audio transmissions, allowing the paging microphone or emergency voice alarm systems to be heard loud and clear.
