Amp output is wired in series vs parallel?

Series: Same current, up to 4X voltage (often factory derated to handle stress from low impedance loads, ie. lower voltage rails- Aragon Palladiums). True bridged/differential.

Parallel: 2X current, same voltage. To keep sides from conflict, a 1 to 2 ohm resistor is used in parallel. "Monostrapped".

W=V*A

On the SST, parallel operation is a factory option, not a switch like the earlier versions. Should be an easy mod.

Ya, definitely oversimplified that at 8:00 AM. Can't deal with current limiting till after the second cup. Thanks Al, for being more precise.

Bryston does use a 1.5 ohm resistor on the parallel 7B's. Not sure about the 28B's. Seen jumper wires for paralleling some Macs that didn't use any resistor. Don't ask me if those were autoformer models. Only other monostrapping I've heard of has been on tube amps, which 95% suggests output transformers. Can't think of any other SS amp manufacturer that has recommended that method.

Mitch, if you're thinking for the Kappa's and maybe even the Beta's, parallel might be the only viable choice of either. However, I did use dual bridged Plinius SA100's on Kappa 8's very briefly and continue to use them with Genesis 350's ( on 4 ohm mid/tweeter, resistive load, dedicated bass amp/active xover). For that one hour on the 8's, it was the best bass I ever got out of them but still sloppy by comparison to the 350's.
