†1. Sensitivity is the lowest level that will produce an output of +4 dB (1.23 V) or the nominal output level when the unit is set at maximum
gain. (All faders and level controls are at maximum positions.)
†2. Balanced.
†3. Unbalanced.
• When dB represents a specific voltage, 0 dB is referenced to 0.775 Vrms, 0 dBV is referenced to 1 Vrms.
