Preamp, EQ and Compressor: How the Channel Strip Works
The PRE70 preamp moves from warm analog tones on one side of its control to aggressive harmonics and distortion on the other. A trim knob attenuates the gain added by the input knob, and a dry/wet knob blends in the distortion.
The EQ7D section offers three bands of parametric EQ. It also includes high-pass and low-pass filters, each ranging from 20Hz to 20kHz, and shelf buttons that change the curve of the high and low bands.
The COMP2R is an OPTO-style compressor with fixed attack and release and a variable-ratio knob. A dry/wet mix knob reduces the amount of compression, a sidechain filter runs from 20Hz to 12kHz, and a mode switch selects snappy compression (NRML MODE) or softer compression (BUS MODE).
