Watts???

[ochuckie]

I'm 60 years old with an old brain and PA systems ????
I recently purchased some used pa stuff to use with my family and friends..
Some Peavey SP3s (8ohm) 100-200watt,two monitors (8ohm) @ 250watts per and a Carvin PA amp HT760M 2 channel with EQ with an output of 175/175 for 8ohm speakers. The amp has an output of 750w @ 4ohm (bridged).
1. What does bridged mean?
2. Will this amp provide power for both the mains (the SP3s) and the Monitors or do I need to get another amp for the other pair?
3. Will the 0hm value change when I pair the speakers?
I'm going to buy a mixer later on.

1. What does bridged mean?

When you bridge an amp, you are turning a stereo amp into a mono amp with twice the power. This is useful for subwoofers and other specialized applications. It doesn't sound like you will need to use this feature.

2. Will this amp provide power for both the mains (the SP3s) and the Monitors or do I need to get another amp for the other pair?

You can safely run 2 SP3s one one side of the amp and 2 monitors on the other side of the amp. I don't know if that will be enough for your situation. If you need more coverage, you need more amps.

3. Will the 0hm value change when I pair the speakers?

If you hook two 8ohm speakers to one side of the amp amp, the amp will see 4 ohms. If you hook four 8 ohm speakers to one side of the amp, it will see 2 ohms. If your amp can handle 2 ohms, you will be fine, but not all of them do.

well said.

a little easier look;
1 speaker per channel=8ohms
2speakers per channel= 4 ohms
4 speakers per channel= 2 ohms...

bridged is using both channels into one source, so to speak.
1 speaker into 2 channels= 8ohms bridged (i think, it could be 16ohms)

i really just like to have 1 power amp for each pair of speakers. if you do that, a crossover would be a good thing to have.

stay away from 2 ohms... please. its quite dangerous in theory. power surge at 2ohms can be lethal.
