Powered Mixer Minimum Load Question (help)

[yakmastermax]

Hey TB, I've got a kind of silly question. I bought a Soundtech S60 powered mixer off of craigslist for a good deal and I'm trying to figure out the minimum load. It has two 1/4" speaker outputs beneath which it says 4 ohms:

Now does this mean that the total minimum load of the amp is 4 ohms and the two speaker outs are in parallel?
Does this mean that the total minimum load of the amp is 2 ohms and each speaker out can have a minimum load of 4 ohms?

I'm trying to figure out if it is possible to use three 8 ohm speakers with this amp. Are there any ways to safely test this?

Thanks guys!

According to this: Invalid Link Removed

it appears that the amp will drive 4 ohms. Not lower. So you can't use three 8-ohm speakers.

Will it drive 4 ohms per output channel or are those two channels wired in parallel and the total load is 4 ohms? Because if it is 4 ohms per output channel I can hook two 8 ohm speakers up in parallel to get 4 ohms then hook that load up to one output and the third 8 ohm speaker to the other output.

Maybe I'm missing something here?

Bump, still not sure

It doesn't look to be a stereo mixer from what I can tell. So you can only run a 4 ohm load. So two 8 ohm speakers maximum.

Yes. There's absolutely no reason to think otherwise. Unless the output is stereo, which I don't believe it is, it's just one amp in there with two jacks. Two 8 ohm speakers is the correct configuration.

Thanks! A stereo mixer would be one with individual power circuits for each stereo output? Adjustable levels for each output? Makes sense now!

Yup. But you don't see this until you get into more expensive units. Yours is kind of a budget model.
