Remember, this is a 70v amp, so any speakers you hook up to this, need a multi tap transformer for each speaker.

This is NOT a subwoofer amp, as 70v transformers tend to roll-off the bass frequencies.

This can be set to ohms or 70v. I have this amp running 6 speakers on 70v and 1 sub on 4 ohms in my back yard.

Right, but 99% of home users would probably not want to be paying for 70v features they are never going to use.

I'm glad you found a specific use for this amp 😀.

Most people would probably want something like a Crown XLS or XTi for less money and conventional XLR/RCA inputs.

Yeah, this 70V thing has my head spinning. Seems expensive even on sale. Glad I still have my old crowns and behringers in the attic waiting to be resurrected.

Yes, this would work, but as others noted, it's not a simple plug and play. You would need phoenix connector, a rolls MB15, or a balanced pre-amp as it's source.

You're better off with this https://www.crutchfield.com/S-Mfv...-1002.html
