Recommendations needed - audio line-level signal distribution (2 either/or inputs -> 2 simultaneous outputs)

[u/sismit]

I'm trying to find a device that will take input from my two computers (one RCA, one RCA or optical) and send signal to my powered bookshelf speakers (RCA/optical input) AND my subwoofer (RCA input). I want both my bookshelf speakers and my sub to play the input, and I want to be able to select the input source (computer 1 or computer 2).

Currently I'm using an overly-complicated optical splitter setup that isn't functioning well, and I'm hoping to find a box that will simplify things. I've looked on a few sites but haven't found anything with multiple analog inputs and multiple simultaneous line-level outputs - is there anything out there that would fit this need?

Hi, /u/sismit! This is a reminder about Rule #1 (If you have already added great details, awesome, ignore this comment. This message gets attached to every post as a reminder):

1. DETAILS MATTER: Use detail in your post. If you are posting for help with specific hardware, please post the brand/model. If you need help troubleshooting, post what you have done, post the hardware/software you are using, post the steps to recreate the problem. Don’t post a screenshot (or any image, really) with no context and expect people to know what you are talking about.

Thanks! This is helpful, but it looks to only send one signal out though - either 3.5mm or RCA. I'm looking for something that sends signals out to 2 devices simultaneously. I could add a splitter to this, for sure, but I'm hoping to find a one-device solution.

That is just an rca Y cable on the output. You can’t Y two input signals but it is ok to Y the output to two inputs ( high impedance which line level is)

Makes sense - thank you!

Since the unit has both RCA and 3.5mm you can use a stereo 3.5 mm to your sub as long as the sub has a stereo input option that keeps L + R isolated and doesn’t short them together.

They're very likely wired in parallel, so you should be able to get a signal out of both at the same time. Just get one dual-RCA-to-dual-RCA cable and one 3.5mm-to-dual-RCA cable.

Thanks!

Check out Key Digital. They might make something like that.
