Locks the Output channel selection key, Output channel ON/OFF key, and Output volume control for each
Output channel.
Select with the Parameter setting knob the Output channel to be locked, and set the key lock function to ON
with the Output channel ON/OFF key.
The Output channel selection key selects an output channel one by one only in numerical order starting from
Channel 1. So, when the output channel selection key is locked at an output channel, the subsequent output
channels are not used unless the locked key is unlocked at the channel by entering a password.
