Any of the 1/4" inputs 1–8 can receive a Line Level signal (i.e. +4dBu or -10dBV). INPUTS 3–8 are fixed at low-impedance (Lo-Z) while INPUTS 1 and 2 can be set to high-impedance (Hi-Z) or low-impedance (Lo-Z) individually. The following are the nominal input level specifications for the eight 1/4" (phono) inputs:

INPUT jacks 1–8 (TRS phone type): -46–+4 dBu (variable)
