At Britfix Repairs, we provide professional Electro-Voice EV ZLX-12P and EV ZLX-15P repair services for customers throughout the UK.

If your EV powered speaker has no power, no sound, distorted output, intermittent audio or an amplifier fault, we may be able to repair the original electronics without replacing the complete speaker.

Repairs are carried out at component level, including fault-finding and repair of amplifier modules, switch-mode power supplies, output stages and associated electronic circuits.

Component-Level EV Speaker Repair

Many powered speaker faults are caused by failed electronic components inside the amplifier or power supply module. Replacing the complete module can be expensive or may not be possible if the part is unavailable.

We inspect and test the internal circuitry to identify the original fault. Depending on the condition of the unit, repairs may include:

• Power supply diagnosis and repair
• Amplifier output-stage repair
• Replacement of failed semiconductors and damaged components
• Testing for short circuits and protection faults
• Repair of damaged tracks, connectors and solder joints
• Final power and audio testing after repair
