FAQ
1. Why is there no noise if the entrance stage is just not linked, and noise shall be generated whether it is linked?
Reply: A lot of the issues on this state of affairs happen on the front-end board. First verify whether or not the front-end board and the back-end energy amplifier board are powered by two energy provides individually. have a take a look at. If there may be noise in each circumstances, add an audio isolator between the front-end board and the back-end energy amplifier board to see if it may be eliminated.
2. When the quantity is turned up, the sound shall be caught, intermittently, and it may be performed usually after the quantity is turned down.
Reply: One of many causes: because of the low energy of the facility provide, the overall output energy of this energy amplifier board is 120W. The advisable voltage is DC24V and the present is about 5A.
Purpose two: If the facility provide is okay, it could be that the facility of the speaker is just too low. For instance, if the output is 60W, however a 10W speaker is linked, and the quantity is turned on, there shall be a freeze phenomenon, and the speaker could also be burned out.
3. There may be an excessive amount of noise when taking part in music, or there’s a backside noise when no music is performed.
Reply: The perform of the facility amplifier board is to amplify the sign. The principle supply of noise is that the radio litter within the surroundings is amplified by the facility amplifier board, so so long as it’s the energy amplifier board, there shall be noise. Subsequently, attempt to use the audio cable with shielding perform. It is usually potential that the sound supply is noisy. Regular cellphones and MP3 is not going to have it. Most of them are on some outdated front-end boards, which aren’t appropriate with our firm’s energy amplifier boards. You’ll be able to add audio isolators or coupling capacitors to check. Can’t be eliminated.
