Page 4: Before You Start
Before you start OCTO - 8 input and 8 output full matrix DSP platform for microphone and line level audio processing. High performance 24 bit AD/DA converters. Processor configuration can be done in real time with computer via Ethernet. All inputs have compressors, equalizer, gate and auto gain functions and are designed for both line and mic level audio signals. -
