• S201 (MIC LEVEL 1 0 dBu/-20 dBu)
• S301 (MIC LEVEL 2 0 dBu/-20 dBu)
Used to set the output level at the MIC OUT CH1/CH2
connector to "0 dBu" or "-20 dBu".
Factory-setting is "0 dBu". (0 dBu=0.775 Vrms)
• S1001 (CCU No.)
This switch is mainly used for the CCU number setting.
The CCU number of 1 to 96 can be set in binary coded
decimal (BCD) using the switches 1 to 8 of S1001. The
switches 1 to 4 determine the number of units and 5 to 8
determine the number of tens. For each digit, the number
of 0 to f can be assigned. The numbers a to f, however,
become invalid.
