The Polycom® SoundStructure® SR12 installed audio solution delivers powerful and flexible audio processing for any commercial sound application that does not require conferencing capabilities. Either alone or linked with up to seven additional systems, the SoundStructure SR12 system is an ideal solution for any sound application, including houses of worship, stadiums, conference centers, hotels, night clubs, and restaurants. A powerful gain sharing automixer with automatic gain control on all inputs ensures consistent microphone pickup in all environments and flexible equalization, dynamics, and cross-over processing enable a broad range of applications. Feedback elimination on all inputs prevents embarrassing acoustic feedback and provides for flexible microphone and loudspeaker placement, and unrivaled noise cancellation technology removes the broadest range of background noises. A central matrix mixer that seamlessly scales from 12 up to 96 inputs and outputs makes setting up multi-zone audio systems a snap.
