Parameters 5

NameTypeRangeBehavior
HEADPHONE LEVELknob—Attenuates the headphone output level.1022
HP MONITOR SWITCHswitch—Two-position switch selecting the headphone output source: left position routes CUE IN only, right position routes the module output only.1022
INPUT GAIN SWITCHswitch—Three-position switch setting input gain for EXT OUT: down = 0 dB, mid = +20 dB, up = +6 dB.1022
MAIN OUTPUT LEVELknob—Attenuates the main module output level going to rear output connectors.1022
