Powered Mixer/ PA help

[Mjespo125]

I've recently purchased a Kustom KPM7250T powered mixer. I run two mics and use it as an extention speaker for a 15 watt crate amp. When ever the guitar is played it tends to lower the volume of the mics. What could be causing this problem?

Just a guess, but it could be the built-in limiter kicking in. It's probably more of a 'speaker protection circuit' but here in fancyland we know it as a limiter and spend a bunch of our time discussing pros and cons of various types and designs.

In laymans terms, it's meant to set a volume threshold over which speaker damage may occur, but since it's a little piece of circuitry and can't hear it has to judge by input signal as measured coarsly by it's simplified detection routine.

That's why it's not kind to multiple sources that are all trying to be loud at the same time...

ORRR it has one of those settings where the bar keep can call out the luckdoor prize over the musak which auto drops when that channel is used.

LOL!

Never considered THAT one...
