MGP32X/MGP24X Owner’s Manual 49
Appendix
Analog Input Characteristics
0 dBu is referenced to 0.775 Vrms. 0 dBV is referenced to 1 Vrms.
*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 to maximum
level. (all faders and level controls are at maximum position.)
*2 XLR-3-31 type connectors are balanced .(1=GND, 2=HOT, 3=COLD)
*3 Phone Jacks are balanced. (Tip=HOT, Ring=COLD, Sleeve=GND)
*4 Phone Jacks are unbalanced.
*5 Phone Jacks are unbalanced.(Tip=Out, Ring=In, Sleeve=GND)
*6 XLR-3-31 type connectors is unbalanced.
Analog Output Characteristics
0 dBu is referenced to 0.775 Vrms. 0 dBV is referenced to 1 Vrms.
*1 XLR-3-32 type connectors are balanced. (1=GND, 2=HOT, 3=COLD)
*2 Phone Jacks are impedance balanced. (Tip=HOT, Ring=COLD, Sleeve=GND)
*3 Phone Jacks are unbalanced.(Tip=Out, Ring=In, Sleeve=GND)
*4 Phone Jacks are balanced. (Tip=HOT, Ring=COLD, Sleeve=GND)
