Ampeg SVT400 issues two channels on head, one input on cab.

Hello,

First of all I spent some time reading over the FAQ trying to find a sufficient answer to this and maybe I'm just missing it by being a little too dense.

Here's the issue. I have an older SVT400 that splits it's output into 2 200w channels. My cabinet is an Ampeg 6x10 with one input. The channels are each rated at 4ohms as is the input on the cab. I need a way to get the full 400 watts out of my head because I'm practicing turned up to 8 and am being annihilated by the three guitarists in my band all playing at 2.

I considered just getting a y-cable but it appears that would be pushing 8 ohms (unless my review of calculations for this are off) into a 4 ohm input. While it would blow it outright from what I've read it isnt advised.

I guess what I need to know is there some kind of adapter i can buy to run bot channels into then out into into one 4 ohm line? or is there another solution to this?

Thanks.

A second 4 ohm cab.

2nd cab is not an option, not only due to price but we have enough equipment to move around now without adding that to the mix.

Don't use a Y adaptor to connect both outputs together. You could blow the amp. Unless your 400 has a switch to connect both outputs together (a bridge mono setting), you can't do it. Check the owner's manual to find out. If you don't have one, find it on line.

If your 400 isn't designed to run both amps together in bridge mono, you're up the creek. You either will need a cabinet for each amp, which you say you can't do, or you need a new amp. Sorry. Sometimes these things happen when you don't plan ahead.

But check the owner's manual to make sure, or contact Ampeg, if you can.

I'll have to contact Ampeg as this is an older head I bought used. Thanks for the advice.

It has a bridge mono switch, or can be slaved together, eitehr one.

PM me if you want a PDF of the manual.
