1. Sensitivity is the lowest level that can produce an output of +4 dB (1.23 V) or the nominal output level when the unit is set at maximum gain.
(All level controls are at maximum position.)
• CH INPUT and MIC INPUT connectors are balanced and others are unbalanced.
• 0 dB=0.775 Vrms, 0 dBV=1 Vrms.
