I would like to know if it isn't dangerous to connect a pair of speakers (Edifier r1000tc power supplied) to Beringher PMH2000 (power mixer).

It's perfectly safe, you just need to use the mixer as if it weren't powered at all, i.e. not use the Speakon ports but the unpowered 1/4" line-outs.

  • Thanks for replying. Ok sounds right. The speakon inputs would need a rare adapter so I was about to connect it using rca cable into the rca outputs from the front. So the fact that it is a powered mixer wouldn't damage the Edifier speakers? Jul 26, 2014 at 16:08
  • @redraw: no. If you used the Speakon outputs with adaptors it would probably cause horrible clipping distortion of the speakers' inputs, but even that shouldn't damage them permanently. But the line-outs on a powered mixer work exactly the same as on an unpowered mixer, so these will work just fine with active speakers. Jul 26, 2014 at 16:33

    Note that while on your specific mixer, it is only the NL2 speakon connectors on the back that are powered, some powered mixers may have powered 1/4" jacks as well. It is important to make sure that you never send a powered signal to a device expecting line level (such as a powered speaker input).

  • Ok. @AJHenderson but my powered mixer doesn't have powered 1/4'' (RCA), right? Now you let me think about it. Jul 26, 2014 at 20:03
  • It has a special MONITOR output too. behringer.com/assets/PMH2000_P0065_M_EN.pdf Jul 26, 2014 at 20:17
