Questions And Answers

What is the lifespan of amplifiers?

From usage to maintenance, many things influence the lifespan of amplifiers but if you look after yours, it should serve you for decades to come. Still, depending on the composition of amplifiers, it’s necessary to replace components every now and then.  

How do I troubleshoot my amplifier?

If your amplifier won’t work out of the blue, here is what you must do:

  • Step 1: Make sure that the amplifier is on: Amplifiers nowadays usually have a dedicated light indicator that tells people whether they are on. If your amplifier is supposed to be on but the light indicator is not lit, determine if it’s plugged in. Don’t hesitate to replace the wires if you notice signs of damage. Furthermore, it’s strongly recommended that you secure your amplifier, keep its wires separated from each other and move them away from metal surfaces. 
  • Step 2: Take the ratings into account: As you put together your audio setup, it’s essential to match the ratings of all components including the amplifier. For example, if the rating of your amplifier is lower than that of other components, issues like static noises, muffled sounds and so on inevitably surface. 
  • Step 3: Ask for assistance from the pros: Look for a reputable store, bring your amplifier there and have it checked by the staff. Of course, if the warranty remains valid, feel free to send it back to the manufacturer. Avoid tampering the components on your own as that will void the warranty.
