Yellow White Red Audio for Projectors

@DustinB3403 You already bought/own these parts?
No, building a list of things for the conference rooms.

You don't need an RCA splitter (thats just silly).
Get a set of RCA cable (Red & White, Yellow is composite video - which you don't need) long enough to go from the projector to your amplifier location.
You need an amplifier, a 2 channel amp will easily drive 4x 8 ohm speakers (2 per channel)
-
So just the RCA cables I have listed, to the AMP, and from the amp to the speakers, basic speaker wire.
Gotcha.

I hit enter before I was done, let me edit my prev post

@FATeknollogee So is what I said correct though?

Yes that is correct.
Just get 4x 8 ohm in ceiling speakers (you don't need 70V speakers)
"Most" modern 2 channel amps will drive a 4 ohm load without any problems.
You get a 4 ohm load, cause you wire 2x 8 ohm speakers in parallel for the left & right sides.
Make sense? -
For what you're doing, since you only have a single source, there's plenty of inexpensive amps to choose from:

@FATeknollogee yeah that makes sense, and your recommending not using these specific speakers as the 70V isn't needed.

Remember "KISS"...no need for 70V, you only have 4 speakers.
There's a time & place for 70V & this ain't it... -
@DustinB3403 Like @FATeknollogee said, you don't need an RCA splitter. With that projector you want a 3.5mm to RCA splitter or cable, like this one from monoprice. Those RCA jacks on the projector are input only, according to the labeling in the picture.

@travisdh1 Good catch.
I usually buy these, only 'coz they look nice but @travisdh1 is correct

So rather than the RCA Audio cables, a 3.5 to RCA (which plugs into the AMP) and out from the AMP basic speaker wire.

Yep, I think you've got it.
-
@FATeknollogee said in Yellow White Red Audio for Projectors:
And from that to the AMP using the yellow and red RCA. From the AMP then to the speakers using basic speaker cable.
Gotcha.

@DustinB3403 Is the audio coming from the PC?

Gotcha.
White and red, yellow is for video.... bad, horrible quality video.
It won't happen in this case, but feeding a video source through an amp and speakers can be both interesting and torturous.

That is something I need to determine if EasyMP also transfers audio. I suspect it does, but need to do my research.
