Analog Input Specifications
0 dBu=0.775 Vrms, 0 dBV=1 Vrms
*1 Sensitivity: The lowest level that will produce an output of +4 dB (1.23 V), or the nominal output level when the unit is set to maximum
level. (All faders and level controls are at their maximum position.)
*2 Combo jacks are balanced (1&Sleeve=GND, 2&Tip=HOT, 3&Ring=COLD)
*3 XLR-3-31 type connectors are balanced. (1=GND, 2=HOT, 3=COLD)
*4 Phone jacks are unbalanced.
*5 Phone jacks are unbalanced. (Tip=Out, Ring=In, Sleeve=GND)
Analog Output Specifications
0 dBu=0.775 Vrms, 0 dBV=1 Vrms
