Got one of these X-overs driving my modified LS5/8.

RH LF output has developed a hiss/crackle. When I first heard it thought
it was rain outside. So beneath the wanted audio, level wise, but very
annoying.

Mute all (inputs and outputs) makes no difference to this noise. And there
does appear to be more hiss than usual on the MF and HF. And the other
three outputs.

So wondering if it is on a PS rail? When the mutes don't kill it? Can't
find a schematic for it.

It's quite a pricey item (for Beyringer) Anyone recommend a decent repair
place? I'll have a look inside for any obviously popped caps etc, but
since it's likely surface mount stuff about my limit, fault finding wise.

Matter of course with Behringer. Replace all the electrolytic caps in
the power supply with decent ones. Nichicon, Rubycon and Panasonic
will be the ones to go for.

** Google " DCX2496 frying noise ".

It's a common fault due to a bad ribbon cable and or lack of insulation under one of the PCBs.

How is it powered. I find anything powered by USB directly from a puter is
incredibly noisy. A separate good quality psu usually is a good move.
