Professional speakers, amplifiers & sound systems repair

We confirm before you send anything Diagnosis and quote first Rijnstraat 76-H, Amsterdam

Amplifiers and active speakers fail in the power stage: power supplies, amplifier boards, protection circuits and cooling. AV equipment adds HDMI boards, DSP boards and Bluetooth modules. We diagnose the fault and tell you whether a repair is realistic for your model before we start.

Questions about Professional speakers, amplifiers & sound systems repair

Can you repair an amplifier that goes into protection mode?

Often, yes. Protection mode is a symptom, and we trace the cause on the amplifier board or the power supply. We confirm whether it is practical for your model.

Do you replace speaker drivers?

This page covers the electronics. Mechanical speaker repair, such as drivers, is handled case by case.

How do I send a repair request?

Use the form on this page with the brand, model and a description of the fault. We reply to say whether we can repair it before you bring or send anything.

Do I pay for a diagnosis?

If a diagnostic fee applies to your device, we tell you before we start. We only begin work after you have approved the quote.

My brand or model is not listed. Can I still ask?

Yes. The list shows what is switched on today. Other brands and models are sometimes possible, so ask first.

What happens to the data on my device?

Make a backup first. We cannot guarantee that data survives a hardware repair.
