Coax digital audio splitter4/1/2023 ![]() The level of a SPDIF AES or any other DIGITAL signal stays CONSTANT whatever audio levels might be. plus 3 db) to compensate for the db loss shouldn't be a problem. then it's highly likely that the only degradation to my SPDIF signal will be a drop in gain, correct (rather than a distorted / artifact-filled signal)? Mogami) and a short gold platted splitter: So just to clarify, if I use short 75 ohm SPDIF cables (with the proper shielding / gold tips, ex. Thus for a simple setup with short runs and a splitter you should be fine. Losing 3dB in a 'splitter' is also no big deal as the signal level tolerance is usually around 10dB or more. The biggest 'killer' is usually cable length (capacitance) which can either distort the signal (round off what should be square) or attenuate it.įor short runs almost anything can work reliable. There are many aspects to the distribution of digital signals and the tolerance of various pieces of gear's inputs is usually pretty wide. ![]() NelsonI got the cheap monoprice ones for an idea I didn't end up implementing, but I tested and it seemed to split the spdif signal with no issues but given that they are passive (and look pretty cheap), I think I'm asking for trouble going with either one. Note: I initially found the following splitters: So I'm looking for a high-end SPDIF splitter. However, I need to find a way of splitting the Kemper's outgoing SPDIF signal (without introducing latency, artifacts, etc). on the SPDIF signal out of the Kemper, and the following:Īudio Interface -> External SRC clocked to Kemper's clock (96 to 44.1) -> Kemper. Kemper (as master clock) -> SRC of my Audio Interface (44.1 to 96) So I'm thinking of implementing the following: The reason for this is that one of the coaxial signals is going to return to my interface, while the other will be used as a clock sync input for an external SRC converter I plan connect to the Kemper. I might just make that part of the A/B or A/B/C comparison.I'm trying to split the outgoing coaxial signal from a Kemper profiling amp in two. Maybe my misguided opinion but now that you mention it I think I have a optical splitter somewhere around here. I believe this would also apply to an optical splitter similar to the one you suggest. ![]() The Vault2i ALSO has an optical OUT but like many others I believe the sound quality is not up to the coaxial. That was my thought going the y-splitter rout. It may not work, but it won't hurt anything either (just don't use cables over 15 meters, and even that won't hurt but you may not get a signal).Ĭan you use optical for the test? There are S/PDIF optical splitters for a few $ (Monoprice has one). So, you might get away with a Y-splitter that you suggested, but I would get a cheapo - the reflection issue will overwhelm any advantage of fancy copper for your tests. At the frequencies of SPDIF (about 3 MHz), the wavelength in cable is roughly 70 meters - the reflected phase will be nearly the same as the outgoing phase for 1 meter cable back at the source (meaning no problem). If you don't match impedances you will have a reflection problem (like light reflecting air to water, but less dramatic). A cable type splitter is best (but the one above won't pass SPDIF signals - the low end starts at 5 MHz).
