Powering mains with bass head?

[mizzou541]

Can you power mains with a bass head?

Sure you CAN, but it probably won't sound as good as using the proper tool for the job.

Bass amps are not generally voiced all that flat, and some are anything but flat.

It's not the power amps, but the preamps that are responsible for this. With some amps, you can use the master effects loop insert point as a power amp input, bypassing the preamp.

You can do it, but it won't be an ideal situation. Just run a line-level signal into the effects return on the head, and it will work as a power amp. You would be able to get more bang for your buck with a real PA-style power amp, though, and you'll only have one channel that will probably only be safe down to 4 ohms.
