3.2 Volume adjustment interface operation instructions

When you need to adjust the volume of a channel, touch the channel to enter the volume interface setting, and

slide the button or touch "+—" to adjust the channel volume.

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：

The first channel has the highest priority, and the eighth channel has the lowest priority

Example：In the automatic call state, when channel B fails or is overheated：

(1) If the other amplifiers are normal and the standby power amplifier is idle, the standby power amplifier is

directly called to continue broadcasting.

(2) If the power amplifier is already occupied by the main amplifier A, the main amplifier B is compared with the

main amplifier A for priority comparison.

The priority of main amplifier B is lower than that of main amplifier A. Therefore, main amplifier B cannot call

the standby amplifier. The main amplifier B can only stand still and show "failure" or "overheating".

The priority of the main power amplifier B is higher than that of the main power amplifier A, and the main power

amplifier B directly seizes the standby power amplifier. Main amplifier B shows "self-tuning."

After the main power amplifier A loses its standby power amplifier, it shows "failure" or "overheating" at rest, and

the main power amplifier A stops outputting. This is an occupancy process.

After channel B takes up the standby power amplifier, it assigns its own volume value to the standby amplifier.

The power amplifier uses this volume value to control its own affiliation, so the volume does not change during

the whole process. Channel B is idle and its volume drops to zero.

(4) When the original affiliation of channel B is restarted, normal operation can be resumed. Channel B

automatically releases the standby amplifier. Re-allocate the work of the power amplifier. The standby power

amplifier is reoccupied by the current highest priority fault channel. This is the release process.
