4 inputs and 8 outputs audio processor

4 inputs and 8 outputs audio processor

Fully programmable 4-input/8-output 24-bit digital audio system processor. Programming is accomplished through front panel controls and a 2X20 character display, utilizing a very intuitive and user-friendly interface. The system software can be used on a PC platform or under MIDI. Can provide signal distribution, gain control, equalization, delay and limiting. Takes up one rack space Four input interfaces - eight output interfaces The output can be assigned to any input 12, 18 and 24dB/octave slope 682ms input delay, 21ms output delay Using Linkwits-Riley, Bessel and Butterworth filters Parametric equalizer: full bandwidth, 1/64th to 4th octave range Each output is equipped with a limiter Intuitive user interface
