SoundStructure SR12
High performance installed audio solution
The ideal solution for sound reinforcement.
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.
In addition, the SoundStructure model SR12 features the same flexibility and ease of installation as the SoundStructure C-Series conferencing products, and is a perfect way of adding 12 additional nonconferencing inputs (such as other line level audio sources) and outputs to a SoundStructure conferencing system.
An innovative OBAM matrix architecture enables multiple SoundStructure units to work together as one large system for unparalleled scalability and flexibility.
All SoundStructure products leverage advanced signal grouping, labeling and submixing that let you leverage yesterday’s work during today’s installation, saving time and money. Plus, exclusive SoundStructure Studio software from Polycom makes configuration easy, and is powerful enough to handle the most challenging acoustic designs.
About Polycom
Polycom, Inc. (NASDAQ: PLCM) is the global leader in telepresence, video, and voice solutions and a visionary in communications that empower people to connect and collaborate everywhere.
Companies choose Polycom solutions because they allow geographically dispersed workforces to communicate more effectively and productively over distances. Using
Polycom voice, video, and telepresence products and services, people connect and collaborate with one another from their desktops, meeting rooms, class rooms, and mobile settings rather than travelling to one place to solve problems.
