1. Sensitivity is the lowest level that will produce an output of +4 dB (1.23V) or the nominal output level when the unit is set to maximum gain.

2. XLR type connectors and phone jacks (TRS) (T=Hot, R=Cold, S=Gnd) are balanced.

3. Phone jacks are unbalanced.

4. Phone jacks (I/O) (T=OUT, R=IN, S=GND) are unbalanced.

• 0dB=0.775Vrms, 0dBV=1Vrms
