Product Details

The SymNet 8x8 DSP network audio processor is the hardware platform for system designs created in SymNet Designer software. Up to sixteen 8x8 DSPs, or other SymLink hardware models, can be networked together in a ring topology via the low latency, 64-channel SymLink Bus. High channel-count processing systems can be deployed in convention centers, arenas, university and corporate campuses, large houses of worship, theaters, hotels, and casinos.

Powered by four Analog Devices SHARC® processors, the 8x8 DSP delivers pristine audio through eight (8) mic/line-selectable analog inputs (with independent 48 VDC phantom power per channel) and eight (8) line-level analog outputs. Coupled with a comprehensive external control connectivity scheme, this powerful tool is the first choice of audio professionals around the globe.

The SymLink Bus offers power and flexibility. The sharing of digital audio and control at an average latency of 80 microseconds between hardware units opens vistas in applications and system capabilities not offered by other systems. 64 configurable digital audio bus channels can be used and reused across multiple units in a ring to far exceed 64 channels of system I/O.

External control options are plentiful. The 8x8 DSP supports RS-232 control systems, the complete line of ARC Wall Panels, other RS-485 control devices, a full compliment of analog control inputs, and an assortment of binary and relay outputs. The rear panel RS-232 port can issue text string commands to compatible third-party devices such as projectors, negating the need for additional external control hardware in some cases.
