Start End
For "CH MUTE," "POWER," and "EMG-MUTE" functions, if operated at the front panel (EMG-MUTE does not
accept this access from the front panel) or if other control input to which the same function is assigned is fed,
their states are changed by subsequent panel operations or control input activations. The following example
shows the change in operation when POWER (Power ON/OFF remote function) is assigned to Control inputs
1 and 2;
Control input 1
Control input 2
Unit operation
Power ON
Control input 1 will still keep the power ON after Control input 2 turns the power OFF, however the unit's
power is OFF.
