Dual mic/line input DSP module is a plug-in module designed for use with the 9000 series amplifiers and can provide two independent balanced inputs. It can handle signals ranging from microphone level to line level by controlling their input sensitivity in 9 increments from -60 to -10dB. Phantom power (24Vdc) can be supplied for condenser microphone use. It can process effect for Tone/Eq/Compressor to two inputs independently.
