Any such device? Optical in to stereo optical out?

Does anyone know if there is a device that will split the spdif signal to stereo and keep it digital? Not looking for a DAC, or a standard splitter that just outputs two identical signals. I’m hoping that there is a splitter that can send stereo L/R from an optical source and keep it digital in the output.

Sorry, your question is not clear. It seems the input is an optical digital but I'm not sure what you want for the two out puts.

Two digital coax connectors, one of which is the Left channel alone and the other the Right channel alone? No such device exists.

P.S. Here is a device which translates between the two common forms of stereo digital sound connections:

L/R stereo digital in to L/R stereo digital out.

Here's a DAC:

For the most part you only have access to the individual channels, L and R, while in the analog domain with these types of devices. If you want to kill just the L or R you simply leave it disconnected.

You explained it right on your first guess. Thanks for the reply. I’m surprised someone doesn’t make a simple solution for this.

I suspect powered speakers with digital ins have a switch on the back (or in a setup procedure) where you assign the speaker to be a L or a R (or mono?). So you feed it a stereo digital signal and it takes only the channel it needs.

That has been my experience.

Ditto. I have a pair of pro monitors and several pairs of computer speakers with digital inputs. All have a switch to set each to left or right. I have never seen an application that requires S/PDIF or AES to split into L/R in the digital domain.

I purchased a pair of phantom reactors, they each have digital audio in. I know that when you connect them digital direct they have a 1ms latency. If they are connected through WiFi it’s 60ms.

Could you use this? four identical outputs, just use two of them?

Ask Devialet -- I couldn't find any sort of spec list or manual on their website after a quick look. It would be very unusual to accept digital inputs and not have a way to tell it which channel to use.

Using them with/for video purposes also? Using a computer or TV or something else for audio/video? If so, then use a DAC.

(Or speak with the vendor how to properly connect/setup/adjust to eliminate/reduce latency .)



If music only, latency shouldn't be an issue or concern.
(Unless when directly optically connected speaker A has latency from speaker B)


IMO, seems like a lot of "work" for expensive speakers.

They probably all receive 2 channel but the app allows you to setup a stereo configuration

In that case you should not need anything special, just a normal splitter though most (all I can remember) digital-input speakers I've used have an input and output allowing you to daisy-chain them without a splitter or eating up a second digital output. Then you just need a cable (coax or optical) from one speaker to the other.

If anyone can find a third-party frequency response graph of one of these speakers, let me know.
