a. Automatic call preparation (Hand tuning switch is at “OFF”):

8 master amplifier in the automatic call state. The priority of the standby power amplifier is
：
10
The first channel has the highest priority, and the eighth channel has the lowest priority
11
Example
：
In the automatic call state, when channel B fails or is overheated
：
12
(1) If the other amplifiers are normal and the standby power amplifier is idle, the standby power amplifier is
13
directly called to continue broadcasting.
14
(2) If the power amplifier is already occupied by the main amplifier A, the main amplifier B is compared with the
15
main amplifier A for priority comparison.
16
The priority of main amplifier B is lower than that of main amplifier A. Therefore, main amplifier B cannot call
17
the standby amplifier. The main amplifier B can only stand still and show "failure" or "overheating".
18
The priority of the main power amplifier B is higher than that of the main power amplifier A, and the main power
19
amplifier B directly seizes the standby power amplifier. Main amplifier B shows "self-tuning."
20
After the main power amplifier A loses its standby power amplifier, it shows "failure" or "overheating" at rest, and
21
the main power amplifier A stops outputting. This is an occupancy process.
22
After channel B takes up the standby power amplifier, it assigns its own volume value to the standby amplifier.
23
The power amplifier uses this volume value to control its own affiliation, so the volume does not change during
24
the whole process. Channel B is idle and its volume drops to zero.
25
(4) When the original affiliation of channel B is restarted, normal operation can be resumed. Channel B
26
automatically releases the standby amplifier. Re-allocate the work of the power amplifier. The standby power
27
amplifier is reoccupied by the current highest priority fault channel. This is the release process.
