Output specifications
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
1. XLR type connectors are balanced.
2. Phone jacks are unbalanced.
3. ST phone jacks (T=L, R=R, S=GND) are unbalanced.
4. Phone jacks (I/O) (T=OUT, R=IN, S-GND) are unbalansed.
• 0dB=0.775Vrms, 0dBV=1Vrms
