Another poweramp question

[clauster]

I'm thinking of upgarding from my little combo to a bigger rig.

I'm consider biamping. My question is is it okay to run a four ohm load on one channel and an 8ohm on the other? My logic says it should be fine, but I'd just like to get some feedback before making an expensive mistake.

Sounds alright to me, although I've never tried it.

Cheers man!

Yep - assuming we're talking solid state here and of course your 4 Ohm load is not below the amp's recommended minimum impedance - the one with the 8 Ohm load on it will just be working less hard.

Thanks, that's what I thought.

Only problem now is persuading the wife to let a rack + cab + sub have houseroom

Although don't get too set on the biamping idea. I tried it (with a 'suitable-for biamping' advertised pair of cabs) and didn't like it. Sounds much better full range into both.

I run the same signal into the two inputs of my power amp. One channel drives an 8 Ohm cab, the other a 4 Ohm cab. A year later, still no problems.

That's usually the case with cabs that are 'suitable for' rather than 'optimized for'. True subs and tops don't work well at all when not crossed over, either passively or electronically.

Aha Bill!

It's your cabs I'm thinking of using (O10 at 4ohm and T39 at 8ohm)

Good to know it can be done without probs on the power amp side, now I've just to persuade the wife that I need houseroom for a bigger rig.

Check out the new Omni 15TB as well, for an all-in-one solution:



Though if I didn't already have some small cabs I'd seriously consider the O10 plus T39 to give me a modular solution.

I like that O15!

Oh, go on then. I'll take your Acmes off you.
