8 Channel Amplifier Matrix Controller
6
and 4 main and multiple standbys (see below for operation instructions in the system settings)
Power (W): output power of each channel;
Volume (%): output volume of each channel, range: 0 ~ 100;
Load (%): the rate of change of zone load, R% = initial load value/actual load value. Initial load value: the
default is the load of the channel zone when it is connected at startup. Users can also manually set the current load
value of the channel to be the initial load value. The actual load value is the real-time load value of the channel
zone. The value 0~99% represents that the load value of the zone increases and the output power decreases.
101%~999% means that the load value becomes smaller, the output power becomes larger, and 100% is normal.
Loading status: shows the current state of loading in each channel zone. There are three states: normal, open
(open circuit), short (short circuit);
1)
Normal: the zone load of the corresponding channel is connected normally;
2)
Open: the zone load of the corresponding channel is not connected normally and is in the state of
disconnection;
3)
Short circuit: the load of the corresponding channel zone is in the state of short circuit. Now please
immediately check whether the load of the connected zone is normal.
Notes:
If the zone is in the closed state: load detection will be carried out in real time to determine the load state;
If the zone is in open state: (1) if the audio input signal of the channel disappears 10s, the channel will begin
self-check to test the load state. The channel will be closed automatically if tested short circuit and the
channel will be opened if tested normal; (2) if the channel audio input signal repeats (more than 1 time) the
same situation as step (1) within 5 minutes, the system will temporarily do not do processing. 5 minutes later,
the system will repeat the steps (1) and (2) to judge the load state.
Amp invoke: the upper part of the display area shows the power amplifier being used by the corresponding
channel, while the lower part shows the name of the main power amplifier that is idle due to automatic switch of
the standby power amplifier; or displays "manual" to show the channel has switched the standby power amplifier
manually.
Working status of external power amplifier:
Normal: external power amplifier is in normal working state;
Sub-fault: the corresponding external amplifier is in sub-normal state;
Fault: the corresponding external power amplifier cannot work normally;
Disconnect: the corresponding external amplifier is not normally connected to this device.

Help function. Click the "Help" button
in the upper right corner of the main interface with the touch
pen. The help window will pop up, and click the icon
to close the interface. The help interface in Figure
2-2 mainly introduces the specific meaning of different displays of the status bar and the power amplifier
status area, as well as some functional prompts.
