Stereo > 2x Mono > 2x Stereo Adapter?

[daanodinot]

I'm looking for an adapter (just one!) that splits a stereo input to 2x mono and subsequently converts both mono's to stereo. It must receive the stereo input with a 3.5mm plug and output the 2x stereo with 2x 3.5mm sockets.

Would this be possible? Thanks in advance!

 

[sdifox]

err, why?

 

[daanodinot]

I can imagine you ask.

I have two pairs of speakers, one left of me and one right of me. I'd like to hear the left channel through the speakers left of me and the right channel through the speakers right of me.

My computer outputs the sound via a 3.5mm stereo socket. To achieve what I want, I see must convert this stereo to 2x stereo, whereby one stereo contains two (identical) left channels and the other two (identical) right channels...

I do the exact same thing at work with my monitor speakers. But I wasn`t able to find anything so I have 3.5 stereo to RCA female->1x RCA male to 2x RCA female->RCA male to 3.5 stereo.

Why on earth would you want to do that?

But anyway, you can just use 1 connector, 3.5mm stereo to 2 mono 3.5mm. Just put one pair of speakers on your right and one pair on your left.

Unless you insist on having 1 speaker from one each pair on the two sides. Then you probably need to replace your signal cables and then do

minijack stereo -> 2 mono, let's call them mono A and mono B. then split the mono A and B into Mono A1 A2 and Mono B1 B2. Then take A1 B1 and feed to speaker Set 1 and A2 B2 to speaker set 2.

Just put one pair of speakers on your right and one pair on your left.

That's exactly what I'm doing right now! As I mentioned:

I have two pairs of speakers, one left of me and one right of me.

The problem though, is that if just split the stereo to 2 mono and feed mono to each pair of speakers, only one speaker of each pair will produce sound. That's why I need need to convert the mono to stereo first.

why? I thought you wanted the 2 speakers on your left play the left channel from your source? nothing stops you from feeding stereo speakers with the same mono signal.

So to be clear, is this what you suggest I do:

[U]Left side[/U]                         [U]Right side[/U]
Set 1 Sp A                        Set 2 Sp A
          < mono < SOURCE > mono > 
Set 1 Sp B                        Set 2 Sp B

[U]Left side[/U]                                   [U]Right side[/U]
Set 1 Sp A                                  Set 2 Sp A
               < mono < SOURCE > mono > 
Set 1 Sp B                                  Set 2 Sp B

all you need is one splitter. The minijack stereo to 2 mono should do it.

 

[daanodinot]

Right, but as I said, when you feed a mono signal to a pair of speakers only one speaker will produce sound. It will route the mono signal to either the left or the right speaker, not both.

humm.. I forgot I was dealing with minijack and not rca...



minijack to 2 rca mono. Mono split to 2 mono, and then back to minijack. Getting messy. so you can do what Railgun did. I don't think there is a 1 converter thing.

Are these just two different sets of the same speaker? Are these powered speakers or are you running 2 amps?

What about: Stereo 3.5 to Mono 3.5(L/R) splitter, Mono(L) 3.5 to dual Mono splitter, Left Set A/B. Do same for right side.

They're two different sets of the same speaker and they're both powered.

Stereo 3.5 to Mono 3.5(L/R) splitter, Mono(L) 3.5 to dual Mono splitter, Left Set A/B. Do same for right side.

Yes, I think that's the same as sdifox suggested. I forget to mention that Set 1 should be connected to a 3.5 jack and Set 2 to RCA. So I was thinking of this:

                                                   L -----------|
                           Stereo 3.5 > Stereo RCA              |                  Set 1 Sp A
                                                   R Set 2 Sp A | RCA > Stereo 3.5
Stereo 3.5 > 2x Stereo 3.5                                      |                  Set 1 Sp B
                                                   L -----------|
                           Stereo 3.5 > Stereo RCA
                                                   R Set 2 Sp B

This is basically a slight variation of what you mentioned. In any case, it seems I need at least 4 adapters. I can't see a way to use fewer than 4.

If its 2 sets of the same speaker and you want the left side to play the left signal on both and the right side to play the right signal on both you only need 1 splitter. Place Set 1 and Set 2s right speaker on the right and do the same for the left side. Use one 3.5 stereo to two 3.5 stereo adapter. Connect 1 adapter branch to each set. Bam!

 

[daanodinot]

Bam!

Hehehe nice try.. but that's the very first option I've excluded.

To give you some more background info: What we've now considered the left and right side is most of the time the front and rear side. The front speakers are on my desk and the rear speakers on some sort of cabinet. I then use the rear speakers for background music and the front speakers for web browsing programs etc.

I also have a digital piano that I want to connect to these speakers . Since the piano is turned 90 degrees, front becomes left and rear becomes right (the scenario we've discussed in this thread). But 90% of the time the speakers function as front/rear so that's why I find it more logical to keep it that way.

Also, they're two completely different sets of speakers: Set 1, Set 2. It will look kinda awkward on my desk. :biggrin:

 

[SithSolo1]

My bad, I read that as "2 different sets of the same speaker" e.g two sets of "Set 1". I guess you meant 2 sets of different speakers.

Yeah, you're gonna need a few splitters.

 

[daanodinot]

I see, yep.
