    Just picked up a used but mint begrudge pmx2000 at a local shop for $145. I have a mic, what's next? Can I plug this into a guitar speaker cab if the ohmage matches?

    The real question: what's a good cheap monitor for practice for this? Its gotta be loud!

    Where to start? Well you could plug it into a guitar cab but it wont sound very good. Guitar cabs and pa cabs do two different things. The range of a guitar cab is really limited and don't reproduce higher freqs very well. PA cabs are much more even in their response. They are made to reproduce sound as acurately as possible.

    As for "it has to be loud" a couple hints about your application would help. Practice PA? Monitor set up? Driving the young girls wild at the local suds factory? What is your plan?

    any insight would be HIGHLY appreciated. anyone willing to read all this gets a cookie.
    I've been reading up a bit, intelligent questions hopefully to follow :p

    1) this is intended for practice and small venues (read: dive bars), JUST for my vocals
    2)We're a two piece, but a loud one. I use a 40 watt guitar amp, and the drummer hits like dave grohl/your standard gorilla. nirvana style rock material

    Do I have enough power to run a passive speaker or two as mains plus a monitor for me?

    the manual (link below)
    (http://www.instrumentpro.com/extra/behringer/BEHPMX2000_man.pdf)

    Berhinger says on the last page that there are two options:
    Stereo mode: 250 W into 4 Ω
    180 W into 8 Ω
    “Bridge” mode: 500 W into 8 Ω

    Crown recommends (http://www.crownaudio.com/amp_htm/amp_info/how_much_power.htm) running below max volume on the mixer with 2 x 250 watt (4 ohm) speakers fed 250 watt each, if I follow. That, or running full volume with 1.6 or even 2.5 times the speaker rating in power mixer wattage, so 250/1.6 = two 150 watt speakers? or more conservatively, two 100 watt speakers? or even one roughly 300 watt 8 ohm speaker in bridge mode?

    How do the monitors fit into all this? They're passive as well, right?

    Ok so you are looking for a pair of passive mains and a pair of passive monitors.

    I would think you would be fine with a set of Yamaha Club series speakers and wedges. You would run the powered mixer in main/mon mode. You then daisy chain the mains to the main output plug, and then daisy chain the monitors to the mon output plug. You would be running the amp stereo 250wx2 @4ohms.

    If you wanted a bit more output, you would need better equipment.

    Get some good quality cables from EWI. I've had good luck with Behringer's cheap XM8500 mics. I have two and they sound good for the price. I actually prefer them to SM58's.

    If you look around you can probably find the speakers used.

    Good luck.

    Thank you much. But wouldn't daisy chaining the Mains, 250w each, require 500w on that channel?
    moreover, with both speakers at eight ohm, the amp would see 4 ohm....?
