Records amp head

[volerium]

This was just given to me a couple days ago and I've been loving it for pretty much everything. Searching the web has yielded zero info on it so thought I'd try posting here and see if anyone could give me a link or any basic info on it. Cool amp for bass though and can't beat free.
Couple things I'm wanting to know is what is the trim knob for? The overload light indicates clipping or what? On the back it has an input for main amp, what is that for and how does it work? And it has two outputs that say 8 ohm speaker, if I run two 4 ohm speakers will that damage something? There's also two fuses in the back that I don't know what they're for, maybe to prevent damage to the head and speakers both.
Thanks in advance for looking and any info.

I know nothing about it, but it probably isn't a good idea to run two 4 ohm cabs in it, though one would probably be OK. And the trim knob is basically to set the output to its highest level without clipping.

Hi.

Free is always nice.

It's a generic "PA" amp intended for vocals.

Couple things I'm wanting to know is what is the trim knob for?

It's used to set the input gain on the "channel strip".

The overload light indicates clipping or what?

It usually indicates that the "channel strip" is clipping.

On the back it has an input for main amp, what is that for and how does it work?

The mixer amp can be used without the mixing section, as an amp head.

And it has two outputs that say 8 ohm speaker, if I run two 4 ohm speakers will that damage something?

Most likely the power section protection is inadequate, so running two 4 Ohm cabs will most probably damage something.
Without knowing how it's wired inside, I'd only use 8Ohm (or higher impedance) cabs.

There's also two fuses in the back that I don't know what they're for, maybe to prevent damage to the head and speakers both.

It says right next to the fuses what they're for.

Pretty safe to say you could run ONE 4 ohm cab or two 8 ohm cabs. No pan control so it is a mono powered mixer not a stereo (two power amps).

The inputs are meant to be used with mics, so they are probably lower than ideal impedance. No problem with an active bass but you'll lose some top end with a passive bass.
