  • I need to know what the minimum number of dedicated 20 amp circuits I need for 2 PL380s, 2 RMX5050s, and 1 qsc pl340? Was figuring 4. Seems 380s @ 18a and 5050 @ 13a

  • 120 V or 230 V?

  • Not sure. I know it's a typical 20 amp circuit at a venue so would say 120v. What would it be in both situations? Thanks

  • You have to know whether the amps are 120 V or 230 V.

    You'll also need to know the load impedance on each channel.

    Then use the attached guide, and follow the 1/8 of full power data as being the typical worst-case (i.e., peaks occasionally on the verge of clipping) current draw.
