If you own an audio amplifier such as Amphony’s microFidelity amplifier then there may be times where you don’t get any audio from your amp. In this post, I will show how to troubleshoot a typical audio amplifier. By checking some of the basics you can save some time since you won’t have to hire a professional nor take your equipment back to your dealer.
The first thing to check when you don’t get any audio from your amp is to verify the power source. If you need a new amp visit GSEAV. Your amp may either plug directly into an outlet or come with a wallwart. If you are using a wallwart then make sure that the DC plug is firmly inserted into the amp. In either case, verify that the mains plug is plugged into your outlet. Also, check that the outlet has power. You can verify this by plugging in another device.
If your amp has a power light then you can skip the above steps since you will immediately see whether the amp has power. After you verified that power is available, check the audio connections to your amp. If necessary, replace any broken audio cables. Also, check that your audio source does deliver audio to your amp. Finally, check the speaker cables. These should be firmly attached to the amp as well as your speakers. When you power up your amp, there should be some slight popping noise. You can use this popping noise to verify that your speakers make good contact.
If your amp makes a repeated popping noise, however, then chances are that your amp has been damaged. The popping most likely results from the amplifier power supply’s short-circuit protection. In this case return the amp to your vendor for repair.
