Please pay attention!
Q: Why the amplifier distortion when raising volume ?
A: Under normal circumstances, distortion is caused by the mismatch between the power of the amplifier and the speaker. Therefore, it can be fairly matched according to the ratio of 1.2-1.5 to 1 between the power amplifier and the speaker
Q: How to match the amplifier and speakers fairly?
A: The best match is 1.2-1.5:1 (that is, the speaker power is 50W, then the power amplifier power is 60W-75W)
Q: The power amplifier is connected appropriately, why is there noise such as electric current?
A: 1.please check whether there is current sound when no load, and whether there is not any current sound when no load; 2.please replace the audio input wire and input device. Inferior audio lines can also cause noise; 3.If there is current noise at no load, you’ll replace the power supply to test again; 4.Power Supply & speaker power do not match with the Amplifier, will also lead to noise problems such as distortion ;5.At the same time, confirm that the surrounding current signals will not cause interference to the equipment; 6.Please make sure all the cable completely pushed into the device,incompletely connections will create distorted.At the same time, it is ensured that there’s a spacing between the output positive and negative audio lines, being close together will cause noise or one of the vital channels will not work;
Q: Can this A07 work with headphones ?
A: This A07 does not work with headphones,3.5mm AUX interface is mainly used for audio output, it can also be used as audio input.But 3.5 mm AUX and RCA input port cannot be used as input at the same time.Please keep in mind!
Note:The use of audio electronic products is closely related to the size of the speaker and the power supply. It should be used in a reasonable combination.
