3/31/2023 0 Comments Coax digital audio splitterI bought a gold-plated Monster branded connector from eBay for $6 bucks and it did the trick. There is no signal loss when splitting Coax SPDIF with a 1 in, 2 out connector. Sorry to necromance this thread, but I figured someone might appreciate this info (I found this post while searching for this a couple of weeks ago): If you exceed the length (without using an amplifier), the signal doesn't degrade, but rather simply never reaches its target (whether it be a monitor or USB port). Sort of like how HDMI or USB cables (I think) can only be of a certain length. So basically a digital audio signal is no different than most other digital signals in that, the data integrity is maintained, but the longer the distance of the cable, the greater the likelihood that the digital data will never reach its intended target. Thus a 'loss' in a splitter or long cable is only important if the digital receiver cannot recover the signal (it is just too small).Ī SPDIF signal (I can't remember details) might be 0.5 Volt peak to peak at the TRANSMIT end but the receiver can correctly work with 0.1 Volts peak to peak so can tolerate a significant loss. 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'm trying to split the outgoing coaxial signal from a Kemper profiling amp in two.
