3. Setup Instructions

3.1 Main interface operation instructions

Operating parameters (Each column corresponds to the real-time display of a channel's operating parameters)：

Temperature (%)：The temperature inside the main amplifier of each channel.

Volume (%)：Volume of each channel, range：0～100.

Power (W)：Power of each channel

Status: The current state of each channel: self-test, normal, fault, power halved, overheated, turn off.

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

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

3． Fault： There are sub-faults, power amplifier faults, and line faults. If the channel amplifier is broken

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

shows "overheat protection" and automatically switches to standby power amplifier; when

the temperature drops to 70° C, it will automatically switch to the main power amplifier of

the original channel. There is no channel installed amplifier, the corresponding column does

not show the operating parameters.

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