EV ZLX Series Input Board

Locating a replacement input PCB board for the EV ZLX series speakers can be difficult. Here’s where I found the part I needed.

The back panel of an EV ZLX-12P

Both of the XLR combo inputs on the back of my EV ZLX-12P powered speaker were blown. The previous owner had connected an amplified signal into the line level input. In layman’s terms, that’s bad.

Everything on the PCB looked fine, but somewhere in the input board circuit something was fried. The 1/8″ stereo aux input still worked, which told me the amplifier board was still working correctly. So I simply needed to replace the input board.

Easy, right? Nope.

Trying to find just the input board and not the entire back of the amplifier was very tough. Most of the places I was finding online were in the UK. The price of superfluous parts plus international shipping was nearly the same price as buying a new speaker. It was hardly worth fixing.

That is, until I found a Canadian supplier that sells the input board separately. I found it buried in a Bosch parts list. In case you need the same part I did, here’s the contact information you need…

This little thing is surprisingly hard to find.

This input board will fit both the ZLX-12P and ZLX-15P powered speakers. I’m not sure if it works with the ZLX-12BT and ZLX15BT models or not, but I would assume that there’s either a different input board or additional Bluetooth board for those models. This board is definitely not needed in the ZLX-12 and ZLX15 passive speaker models.
