C-Mark DRD28A DSP Audio Processor
The DRD28A audio processor is a 1U device with multifunction of signal mixing, route, equalizer, etc, which simultaneously handles up to 8 channels analog signal with Line/Mic input.
With an internal 200 MIPS SHARC processor, it processes audio signals with 40-bit floating-point precision by using C-MARK RS1200 software.
Therefore DRD28A audio processor is capable of processing high quality audio signal. It has been widely applied in various occasions, including professional and entertainment applications.
