Wireless mic repair – Line 6 XD-V30

Wireless mic repair - line 6 XD-30

This wireless mic repair came in from the singer of Newark soul band the Acetones.

Both units powered up but no sound came from the receiver when the mic was used.

Upon investigation I discovered that the transmitter and receiver were able to communicate. They use 2.4GHz. The unit has 6 wireless channels, all of which were communicating, but not passing audio.

I discovered that the connection between the capsule and the transmitter was broken. The connection was made by 3 sprung pins on the transmitter and 3 concentric gold plated rings on the capsule. It’s a nice idea to allow easy swapping of capsules and easy manufacture, but here it wasn’t working properly! I soldered the two modules together permanently to ensure a good connection.

PA Repair – Prosound 1000

PA Repair

This PA repair, a Pro Sound1000, was brought to me with a couple of reasonably common symptoms. One channel was producing no output, the other channel was very quiet. To be honest I’m surprised that the internal fuses hadn’t blown. The symptoms pointed towards what is probably the most common problem with solid state PA repairs – several of the output devices were short circuit in one channel. This affects the shared supply rails of the power amp, which probably caused the effects in the other channel. I replaced the transistors from the faulty channel and both channels ran fine.

Whilst fixing the amp, I noticed that the reservoir capacitors were leaking, so these were replaced as a precautionary measure to prevent future damage.
