SPDIF amplifier
in [Design]
|
From: Dirk Bruere at NeoPax on 1 Mar 2007 11:00 I want to amplify and distribute SPDIF to three systems over maybe 100m feeding into systems that take AES/EBU. So, thinking of putting the SPDIF through an amp and then splitting it through a 4 Way off the shelf passive F- Splitter. Can anyone recommend a cheap amp that might be suitable for this? People have suggested TV amps but I can't seem to find any that don't cut off below about 88MHz (FM). I'd also like to boost the voltage a bit as well since I'm feeding into EAS/EBU. I know I could probably put one together using a buffer amp chip or something but I don't want to have to get into making, soldering and packaging a solution of my own. Someone somewhere must do what I want at a reasonable price. I know someone does it at an *unreasonable* price - approx $350, but that seems aimed at audiofools. Dirk
From: Hawker on 1 Mar 2007 11:19 Why don't you buy or build a COP and convert it to AES then send it. AES is designed to send on long runs, SPDIF is not. Since your going to AES in the end just convert to AES at the source and use balanced CAT-5 cable to get it to the XLRs on the AES.

Anyway, building is out of the question for various reasons. Still, your advice sounds good. Thanks Dirk

If/when I get my AES signal how do I split it? Can I just join the cables at source or do I need do do anything with resistors etc to match impedances etc? Dirk
