AIYIMA A07 HiFi integrated stereo class D amplifier

300W+300W Dual Channel audio amplifier ,Mini Power Amplifier, More powerful, Sound great

Build quality is surprisingly solid,Nice touch

The dual 300W shocking bass output is compatible with passive stereo speakers of most sizes and impedance specifications

Two input ways :3.5mm AUX Audio input(Can match our T9 tube Amplifier,The T9 Power Amp as the DAC use for A07)/ RCA Audio input

Note:When using a 32V or 36V power supply, the sound quality of the A07 stereo amplifier will be better, the distortion rate will be low, and the service life will be longer, but the power can only reach the size of the voltage multiplied by the current. For example, using a 32V 5A power supply, the power can only reach Max 160W.

Therefore, please choose the speaker and power supply reasonably according to the requirements, so that the machine can achieve the best use effect.

A07 Use TPA3255 Chip, digital audio amplifier BTL bridge max power output 300W x 2 channel design,THD less than 0.008% when working continuously

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.

Q: How to match the amplifier and speakers reasonably?

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 correctly, why is there noise such as electric current?

A: 1.please check whether there is current sound when no load, and whether there is no 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 can 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 is a spacing between the output positive and negative audio lines, being close together will cause noise or one of the 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.

Why only one channel work ? Is it defective?

Since the electronic product is not used alone, it needs to be used together with other electronic equipment such as power supply, audio source, speakers, etc., so the problem cannot be generalized to be considered as the problem of this product, and it needs to be ruled out one by one!

1.Please confirm the connect is correct before use!

2.Are the positive and negative wires connected to the speaker connected together?

A:Please separate the positive and negative wiring with an insulator,then shut down and restart to use.

3.Used with mismatched speakers, the power supply used does not have enough power to drive the speakers, or the speaker power is too large

A: Please check our detail description as below ,Our A07 with a free DC 32V power adapter,Use this power adapter,the A07 output is about 65-80W for per channel.

4.Did you replace the chip by yourself?Or the chip inside is loose ？

A: Please check it confirm no problem.

If Still have problem,please tell me replace,we’ll be responsible for our AIYIMA Brand products!

Using the corresponding power supply, the output power diagram of the A07 amplifier

Therefore, it can be reasonably matched according to the ratio of 1.2-1.5 to 1 between the power amplifier and the speaker
