PA portable Mackie Reach repair need help

[randytian]

I had a mackie reach, everything is fine except my physical volume not function which how you turn clock wise or anti clock wise, it can’t bring the volume up, but able to volume down , any idea what is the possible part faulty? cause it drop once it other button or thru app is function accordingly, I had seek to local agent but they refuse to repair cos is discontinued product, however it still good in performance except to fix this issue, it may cause inconvenience in live operation. I try dismantle to hopefully able to spot some cable break or the rotary control able to change? But the compartment is very difficult to deep in, look forward some one come across this product how can get repair thank you in advance

It would be helpful to know where you are based. This is mostly a UK forum but there are members from other parts of the World so tell us where you are and maybe somebody can suggest a tech who could help.

The volume controls are inputs to the digital control section of the unit.

As they work one way but not the other, it might mean that it's a software issue, so you could try a factory reset. According to the manual:

"Simply press and hold the Mon, Channel 2 and Channel 4 buttons simultaneously to reset the Reach Professional PA to its factory settings. The LEDs flash when it has reset"

Note that this will erase any setting or Bluetooth pairings you may have set up, but if it does fix things, then it's worth the effort to get it going again.

If it doesn't make things better, then it's a hardware issue. Given the one-way aspect of the fault, the control is probably a rotary encoder, rather than a potentiometer. If you can take the speaker apart to access the control boards, you may find that spraying some contact cleaner inside the volume encoder/pot might fix things. But if it's sealed you may have to take it apart or replace it. But also look for a bad solder joint.

Anyone with some electronics repair knowledge should be able to work on it.
