    Which one is for the 4ohms and which one for the 8?

    I have a Ampeg SVT 350H and a Ampeg 410HE does it matter which one I use?

    I am looking to buy either a Ampeg SVT-15E or SVT 410HLF to go with it, can I plug these into this head?

    Use either jack. Plug in 1 4ohm cab or two 8ohm cabs.
  3. The ohms that it's referring to are the ohms of the cabines you'll be plugging you amp into. If you plug your amp into an 8 ohm cab you'll run your amp at 200 watts. If you plug your amp into a 4 ohm cab or run it parallel into two 8 ohm cabs then you'll be running your amp at 350 watts, hence 350@4ohms. I hope that makes sense.

    As far as the cabinets are concerned, you can't run that particular head under 4 ohms so if you want to run your head into 2 cabs then make sure they're both 8 ohm cabs, because two 8 ohm cabs work together at 4 ohms when ran paralleled with one another.
