GK MB200 as a power amp?

[samson3382]

Could this be done?

Specifically, at a gig.
Vocals, guitar, & keys in monitors, maybe some fiddle.
Powered monitors are run off aux 1.
Guest musician gets a passive floor wedge run off aux 2 with the MB200 powering it.
1. Straight into the front input?
2. Or aux in with no gain or EQ?
If aux in, what type of cable would be best?
It's a headphone jack, or 1/8" or 3.5 mm, but I don't know if it's ts or trs.
3. Find an alternative.
A bandmate has a tiny power amp we've used with success before.

Probably the aux in. The front panel input isn't line-in so an impedance mismatch...

which is to say that it would work but it would probably suck.

Yeah, signal would go through with the pad set on and the gain very low but the sonics are likely to be god-awful... I forget if the mb-200 has an effects loop but using the return might be a good option if it does.

CL for a decent led-sled poweramp and an old analog rack eq won't set you back much and then you'll have more or less a proper monitor setup.

No effects loop.
When I run an iPod into the aux I get a nasty hum, but I'm just using a cheap stereo aux cable.
Would a mono or ts be better possibly?
Could be an issue with the jack as well.
I used to have a decent crown 2 channel power amp, wish I had never sold it, for next to nothing.

I have a rackfull of great sounding EV / Dynacord heavy amps... If the freight wouldn't kill me they'd be long gone. Other than a couple of ca/9's for subs, all my heavy weight stuff is replaced with qsc plx or plx2 stuff...
