4 inputs / 4 outputs internal DSP in Pi, DENEB and DALIM power amplifiers and DSP_PowerPack modules
This Digital Signal Processor is a very versatile processor useful for any kind of sound system and configurable for any sound application possible. It is real time fully programmable directly from the front panel in the amplifiers or through Ethernet or USB by means of RAM Audio own control software, RAM_OCS.
