See the figure on the right for wiring. J ST2 OUT jacks These unbalanced phone jacks output ST bus signals, with a nominal output level of +4 dB. See the figure on the right for wiring. K MATRIX OUT jacks 1/2 These unbalanced phone jacks output Matrix 1/2 signals that are a mix of MIX buses 1–4 and ST bus, with a nominal output level of +4 dB. See the figure on the right for wiring.

You can route either MIX (Variable) bus signals or MIX (Fix) bus signals to the MIX OUT 1–4 jacks of the MC32/12 and MC24/12. You can select either one of these output signals in the Variable/Fix select section. If the M1–M4 switches in the Variable/Fix select section are set to FIX ( ), the corresponding MIX OUT jacks will output MIX (FIX) bus signals. Since each channel’s output level for the MIX (FIX) bus signals is fixed, the corresponding MIX OUT jacks will function as group output jacks. If the M1–M4 switches in the Variable/Fix select section are set to VARIABLE ( ), the corresponding MIX OUT jacks will output MIX (VARIABLE) bus signals. Since each channel’s output level for the MIX (VARIABLE) bus signals is variable, the corresponding MIX OUT jacks will function as AUX output jacks. The GA Diversity function will enable you to configure a flexible bus system, such as four groups and six AUX sends, two groups and eight AUX sends, or 10 AUX sends, etc., depending on the application.

Press down the M1 switch ( FIX) in the Variable/ Fix select section (see page 6). The FIX indicator will light up. The MIX OUT 1 output channel will receive the MIX (FIX) 1 bus signal, and the MIX OUT 1 jack will function as a group output jack. 2. Press the M1 switch again to set it to ( VARIABLE). The FIX indicator will be turned off. The MIX OUT 1 output channel will receive the MIX (VARIABLE) 1 bus signal, and the MIX OUT 1 jack will function as an AUX output jack. 3. Set the M2, M3, and M4 switches in the same way. You can set MIX OUT 1–4 channels to “FIX” or “VARIABLE” individually.
