High/Low Impedance speakers

Okie · 5th January 2007, 12:11 AM

I sing with a praise band at church. Someone donated 4 new monitors to replace our aged ones. The old speakers have RCA (Phono) jacks and the new speakers have XLR type jacks. Simple Ohm's law tells me that lowering the impedance will increase the amperage, but does this apply to these speakers?

What makes you think they are different impedance? XLRs are common on all types of box. Even if they are lower impedance, we should still be able to get you sorted. Do you have access to a simple multimeter that can measure resistance, and could you tell us about the amp that you use to drive them?

Perhaps he's talking about the characteristic 110 impedance of the XLR vs 75 of RCA?

That's it, and the old monitors are 8 ohms each and the new are 4 ohms.

Are they self powered?

Yes, they have a 120v power cord on each new monitor.

Let me guess, Hotspots or Anchors?

I don't know

Hey Okie, so what you will want to look at is what the monitors are fed from. Does the RCA cable plug into a snake cable that goes to the mixer in a remote location or is the mixer right there?

No snake. RCA jacks are mounted on stage with the wire running in conduit to the back of the Auditorium and connected to a sound mixer board (screw terminals).
