68 MG124CX/MG124C Owner’s Manual

Specifications

Reference
■Input Specifications
Where 0 dBu = 0.775 Vrms and 0 dBV= 1 Vrms
* 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 the maximum
level. (All faders and level controls are at their maximum position.)
■Output Specifications
Where 0 dBu = 0.775 Vrms and 0 dBV= 1 Vrms
*The MG124CX feature is described first, followed by the MG124C feature in brackets: MG124CX (MG124C)
