Newbie with some questions

  1. Ok i'm finally ready to make the move from a combo amp to a stack setup. I'm kind of leaning towards a pre and poweramp setup on top of a 4x10 cabinet but i know nothing about any of that can someone explain this bit about ohms that i keep hearing and how to pretty much set all of this stuff up so i don't blow it up first time i turn it on thanks.
  2. There’s nothing to it, really. Most bass amps have the pre-amp and amplifier in one cabinet, while you’re merely separating them (but I guess you already knew that). Ohms shouldn’t be an issue at all, because most bass cabinets are 4-ohm, and most power amps are also rated for 4 ohms.

    The nice thing about using separates is that you can easily add components to the system – like a good-quality professional compressor (as opposed to those cheap stomp box units), parametric equalizer, etc.

  3. Sounds good that i can't mess anything up too bad then but in the end the talk about compressors and what not you confused me... i have no idea what any of that is

    All he's saying is that, by using a separate pre and power amp, you have the flexibility to put other signal processors (such as a compressor) in the signal chain more easily. Not a big deal; you don't have to unless you hear a need.

    Ohms really only come into play when you're using multiple cabs. If you're using a single 4X10, you should have no impedance issues to contend with.

    Just always remember to turn your power amp on LAST before you play, and turn it off FIRST after you play. You don't want to be making connections in your signal chain with the amp on. :eek:
