Re: Allen & Heath Xone:92 mixer problem - faulty phono channel outputs on one side on
Thanks for the clarification. Yep, you understood correctly - there is a bad channel board. I've now labelled the boards after the error (I put the same boards back in the same slots...).
Apologies for the naïve question - I'll test at the points that redwire has kindly suggested - are there other particular strategic points that you would recommend testing at? I've attached the schematics for the board if you have the time....

Nice, I'll give that a go. Thanks!

Re: Allen & Heath Xone:92 mixer problem - faulty phono channel outputs on one side on
Actually... I made an error earlier - when the channel 2 (the faulty channel) PCB board is swapped with the channel 3 PCB board, the problem moves to channel 3. I guess the fault is somewhere on the channel board

Re: Allen & Heath Xone:92 mixer problem - faulty phono channel outputs on one side on
A bit of an update - I've tried cleaning the ribbon cable connections with no success. I've also swapped around the channel 2 (the faulty channel) PCB board with the channel 3 PCB board - channel 2 is still faulty after swapping the boards so I guess the rules out a fault with the channel PCB board.
I'm guessing (naively!) this points to a problem on the slave or master boards, or the ribbon cable. I'm assuming that the other boards wouldn't produce such a channel-specific fa...

Modular - separate PCB boards for each of the channels. What were you thinking?
I'm going the faulty channel PCB board with one from a working channel and see if this isolates the problem...

Not sure if this is useful for diagnosis, but the level indicators only light up on the right side as well as only outputting sound on the right side

Re: Allen & Heath Xone:92 mixer problem - faulty phono channel outputs on one side on
Thanks. I've tried this but no luck unfortunately. I've also opened it up and couldn't see any bad solder joints on the jack board. Is there a process I could use to diagnose whether if phono pre-amp is blown? I'm fairly novice with electronics, although I have a multimeter!
I was thinking of swapping the jack board with another channel to see if the problem is on the channel board....

Many thanks. I'll give that a go and have a look inside

Allen & Heath Xone:92 mixer problem - faulty phono channel outputs on one side only
Hi all,
Wondering if anyone here can help – I have an Allen and Heath Xone:92 silver mixer with one faulty channel – channel 2 is only outputting on one side (right side) when set to a phono input. It works fine with a line input, and all the other channels work perfectly with phono and line inputs. I'm not sure when this happened as I rarely use the faulty channel – it could well have been like this for years! Any thoughts on what might be causing the fault and how it could be repaired? I can do some basic soldering, so I'm hoping I might be able to fix it myself.
