SQ6 Pan Encoder Issue

I had a chance to work with a friend’s brand new SQ yesterday and man, did his panner dial work great. Not like mine which skips, runs backwards, is hard to set because of erratic behavior.

Makes me think I have a bad encoder pot. My SQ is way out of warranty. Has anyone had experience replacing this sort of part on an SQ? And will A&H sell me just a “raw” part?

FWIW, I have good bench-tech skills and all the correct tools to do this job if it’s worth tackling and I can get the part.

I will put in a support ticket next.

Maybe the part would be easier to open and clean than having to solder it.
But of course I don’t know.

Hi tourtelot,

I’ve got also the same problem.
Got changed some encoders, but after 3 more years, again another encoder got this error.
Seems to be a common problem at A&H SQ and dlive. If you search the forum you’ll find also other users.

Yes it’s possible to get spare parts. But as I’ve seen, you’ve to remove the hole display PCB, because they are front mounted.

Let us know about the successful repair!

PS: is there an official statement from A&H about this (as I know) wide & common failure?? - would be nice!

Has anyone tried simply resetting the panel to cure this issue? I think probably not and that it is a parts quality issue (faders as well) but I thought I’d ask before I get out my screwdriver.

I really can’t imagine that the problem can be reset in software in any way.
But until you’ve solved the problem, here’s still a tip: By holding down the “Reset” button and turning the pan encoder, you can choose between the 3 fixed positions L, C and R.
This way, in an emergency, you should be able to quickly set at least the most important center position without having to turn it around for a long time.

They cant really be cleaned. They need replaced.

Ive replaced a few, if youre a competent board tech the soldering isnt bad they are thru hole devices. The hardest part is the amount of disassembly to get to the surface board.

Here’s also the same problem called rotary encoder “jitter”:
