M/S Amplifier
(5)After channel B releases the standby power amplifier, the standby amplifier will assign the volume value to
channel B. Channel B uses this volume value to control its own affiliation, so the volume will not change during
the whole process. The spare amplifier is idle and its volume drops to zero.
(6) The whole process of active/standby switchover is done automatically by the machine. No manual intervention
is required and no dialog box will pop up.
b. Manually call the standby power amplifier (Hand switch is "ON") ：
(1) Artificially moves the anti-white cursor to the designated channel and presses the digital wheel. The standby
power amplifier is used for the designated channel, which is called manual tuning.
(2) No matter the status of the channel is off, standby, normal, faulty, overheated, and the original is self-adjusting
or manual tuning, you can manually call the standby amplifier.
(3) Manually force the priority of the standby power amplifier above the automatic call. The machine will analyze
the situation and a corresponding warning box will pop up to remind the operator. After the operator makes a
decision, the machine then stays as it is, or moves to the designated channel.
(4) Regardless of whether the original is a self-adjusting or manual tuning state, as long as the user confirms that
the hand is tuned to a designated channel, it enters a manual tuning state.
(5) The state of manual adjustment is the result of human intentions, so it does not support any function of the
self-regulation state. To restore the auto-tuning state, simply reset the auto-tuning state by touching "OFF" in the
"manual switch".
Note: Because there are 8 main power amplifier channels, it is not allowed to stop the maintenance when there are
several channels fault or overheat cannot work and other channels are playing.
