pf 500/ speaker cabinets hookup

Discussion in 'Amps and Cabs [BG]' started by ampeg2, Jul 17, 2012.


  1. I would appreciate advice connecting a PF500 to a 400 watt carvin 4/16 ohm 2x10 cab plus a swr 15 -200 watt 8 ohm .Can I just daisey chain ? What setting should I use on the carvin( 4 or 16 ohm?)I also have another carvin 2x10 which I may use in the future,how would I connect it in .Thank you..
     
  2. All at once?

    The 500 is only stable to 4 ohms.

    Do NOT hook up your Carvin and SWR cabs together with the amp. That's an impedance load of 2 Ohms, which could potentially damage your amp. If your two Carvin cabs are the same, you can hook them both up in 16 Ohm mode, for a total load of 8 Ohms.

    If you want to achieve the maximum wattage out of your amp, you need two 8 Ohm cabs.

    Pick one 4 Ohm cab, or two 8 ohm cabs.

    Another side note, I've never seen cabs that can switch impedance. Anyone else? I'm guessing they're 8 Ohm speakers and the internal circuitry lets you switch the speaker wiring between series and parallel?

    I'd double check your 210s to make sure that this is what they do. Try and look up the manuals.
     
  6. I just checked.Im wrong as usual the 15 is 8 ohms,Im sorry.. will the 15 plus one 2x10 work? The carvin is model 2210 w/ a 4/16ohm switch. I set it at 16 ohm and use it alone now.Have no idea how many watts im getting.

    The speakers have two voice coils.
     
  8. You could use the 2 x 10 in 16 ohm mode with the 8 ohm 15. This makes a 5.33 ohm load-safe for your amp but be careful as the 15 will be getting double the power of the 2 x 10.
     

  9. Not in this case..............

    When a cab can go between 4 and 8 ohms, that is a dual voice coil speaker.

    In this case, the choice between 4 and 16 ohms indicates a pair of 8 ohm speakers that let you select between series or parallel wiring.
     
  10. I'm quite sure Jimmy knows this. ; )

    Or it's a series/parallel switch.

    Edit - nevermind, already covered.

    DOH! I r dum. Never mind.
     
  13. So: one 2x10@16+one15@8=5.33 ohms=__watts : one 15@8=8 ohms=300 watts : two 2x10@16=8 ohms=300 watts: : two 2x10@16+one15@8=4 ohms=500watts: one 2x10@4=4 0hms=500watts (how about two 2x10@4 =__watts,or two2x10@4+one 15@8=___watts ....Are the combinations above ok? thank you, thank you..
     
  14. yes

    no

    I wouldn't but it should be OK
     
  15. Thank you for your help guys I really appreciate .....ready to connect and play.
