    On the back of my Crate 220 watt speaker head, there are two speaker outlets. One says 150 watts at 8 ohms, and the other says 220 watts at 4 ohms. Can anyone put this into layman's terms and what each setting would mean? Thanks a lot :) deftone

    It means that the one marked 8 ohms will put 150 watts into an 8 ohm load(one 8 ohm cabinet), and the one marked 4 ohms will put 220 watts into a 4 ohm load(1x4 ohm cab, or 2x8 ohm cabs).
     
  3. There's no difference between the two jacks. The 160watts/8 ohms-220watts/4 ohms just tells you the overall output of the amp. The two jacks are undoubtedly just hooked up in parallel, so you can use one or both of them.

    Mike I wondered about that myself.

    Never heard of a solid state amp having different taps for different loads like a tube amp, but I am by no means an expert.
     
  5. embellisher,

    Well, just to be sure, I checked the manuals online at the Crate site before replying. I didn't know what model he had, exactly, but the 220-watt heads (Flexwave?) matched the output specs but made no mention of different outputs. From the little bit I could see of the back panel arrangement, it seemed like the output labeling might accidentally line up with the two different output jacks, though.
