The system partition status descriptions
Partition status means that the real-time job status of local speaker loop bus, which includes the loop bus open,
short-circuit, ground, normal and currently working audio. When system diagnostics speakers’ partition bus that has
short circuit, in order to protect the power amplifier, it will immediately stop outputting audio signal of the current
partition; when system diagnostics speakers’ partition bus that has grounded and open, it does not stop outputting
audio signal of the current partition, but it will beep and fault indication to alert the user and record the time point
of failure and failure of the partition, for the specific view, please refer to the following sections.
