The Pulz DSS88 8-In, 8-Out Digital Speaker Processor is designed to deliver high quality DSP processing and superb audio quality and adequete control options for professional sound reinforcement for fixed and touring installations, nightclubs, large venue sound systems and more.
The DSS88 features 24-Bit A/D converters 96kHz sampling rate and an array of DSP functions that include crossover, delay features, compression, limiting, feedback control features and much more.
An intuitive 2 X 24 back-lit LCD display helps navigate options through its extensive feature set and is also easy to see in dimly lit venues. The DSS88 will store up to 30 total presets. A preset file captures all current settings and stores complete control data for all channels and all audio functions.
