BSS - SW9088iis DSP Hardware
January 2008
The Soundweb 9088iiDSP unit is the heart of the Soundweb system. As a standalone single rack space device it has all the facilities required for a sound system processor - 8 inputs, 8 outputs, a DSP engine, networking for connection and signal distribution to other soundweb units, Analogue GPI control interfacing, and RS232 ports for external control by PC or AMX/Crestron type systems. Plug in an audio source, an amplifier, and speakers and you are away
All the facilities are included in a 9088ii, there is no additional Soundweb system hardware required to begin building physical systems. The only option decision to make is a choice of line input, mic/line input cards or AES/EBU Digital input/output cards. Each digital card accepts 2 stereo inputs at sample rates from 32khz to 96kHz, and can output at 44.1, 48, 88.2, and 96kHz. When digital inputs are used, the analogue outputs remain in use as a mirror version of the digital output.
Each Soundweb 9088ii can typically hold up to 12 completely different system designs in its own memory. Programming the unit is accomplished via the Soundweb Designer software.
For safety-critical systems, the Soundweb 9088ii has an opto-isolated output which functions as a watchdog: the opto-isolator conducts when power is applied to the unit and the software is functioning correctly; it is cut off if there has been a power failure or other fault. This function can be used to trigger alarm systems or to construct redundant systems.
