the debugging module is used for:
closing the AVC debugging function and the DRC debugging function of the audio equipment, adjusting the front-end amplification value of the audio equipment, and determining the front-end amplification value currently corresponding to the audio equipment as the rated front-end amplification value when the output power of the audio equipment is equal to the rated output power corresponding to the target register value;
starting an AVC debugging function, adjusting an AVC value of the audio equipment, and determining the AVC value currently corresponding to the audio equipment as the AVC threshold value when the output power of the audio equipment is equal to the rated output power corresponding to the target register value;
when the IC input signal exceeds the AVC threshold, it is input at the AVC threshold size.
5. The apparatus of claim 4, further comprising:
and the setting module is used for responding to configuration operation, determining register values corresponding to the remaining volume values according to the register values corresponding to the maximum volume value of the audio equipment, and setting the volume control curve template according to the register values corresponding to all the volume values of the audio equipment.
6. The apparatus of claim 4 or 5, wherein the second adjustment module is configured to:
when an output power adjustment instruction is detected, adjusting the front end amplification value of the audio device to the rated front end amplification value, and adjusting the AVC value of the audio device to the AVC threshold value, so that the output power of the audio device is equal to the rated output power corresponding to the target register value.
