A Question about Mono RCA and Center Speaker

post #1 of 9
Thread Starter 
Hey guys,

I currently have a Quadraphonic surround system (Front jack and Rear jack occupied) and i'd like to add a center speaker for 5.1 surround.

My question is, Will it work properly if I just take the speaker (RCA), plug into a female mono RCA to male 3.5mm adapter and stick in my center jack?
I plan on using something like this

Will the specific speaker work properly without needing any amplifier or something like that?

Also, does the Center speaker need to be a decent/big sized or a small one will do?

Thanks in advance.

Hi. You asked if you would be needing an amplifier for your center speaker. My couple of questions to you are:
  1. Is this a PC audio setup, or a HT (home theater) setup?
  2. What kind of speaker/setup do you have?
  3. Do you have a receiver? Or is the pre-amp built into the subwoofer?

If you have a receiver like this one:


You can just take a Y RCA cable, I believe the one you were referring to, and connect it to the center/subwoofer jack on your sound card.

It's connected to my PC. I currently have a 4.1 Setup connected thru an amp but I dont have any more room on that one. I was wondering if I could use a mono RCA to 3.5mm just for the single center speaker, no need for left/right or that stuff. Shouldn't it work?

If you're talking about hooking a regular passive speaker up to the 3.5mm jack for power, no it will not work. You HAVE to have an amplifier to power a speaker, period. If its not built into the speaker, then it must be seperate.

Correct me if I failed to interpret, but you are asking if you can do this:

Sound card ---------> Speaker (via mono RCA to 3.5mm cable), then the answer would be no. The impedance would be too low. You are using passive speakers and they need to go through an amp.

I thought it happens only when using 2xRCA to 3.5mm :\\ Yea my plan was

Speaker -> plugs into Female Mono RCA to Male 3.5mm -> 3.5mm end into the sound card center jack.

That would work, if your speakers were somehow powered. But I am assuming you are using passive speakers. It would help if you told us what center speaker you are planning on using.

Just find a used receiver somewhere . Problem solved. Even Dolby Prologic isn't half bad (that's what mine is).
