1. Self-inspection
：
Self-inspection at boot time

2. Normal
：
The channel's amplifier is in normal playback.

Fault
：
There are sub-faults, power amplifier faults, and line faults. If the channel amplifier is broken
14
and no standby power amplifier can be called, no signal will be output.

4. Overheat
：
When internal temperature of the main power amplifier of this channel detects 76°C, it
16
shows “overheat protection” and automatically switches to standby power amplifier; when
17
the temperature drops to 70°C, it will automatically switch to the main power amplifier of
18
the original channel. There is no channel installed amplifier, the corresponding column does
19
not show the operating parameters.

5. Turn off
：
The channel's power is turned off. Eight main amplifiers and one spare amplifier can be
