Extra Info:
Somewhat vintage but still useful.
* Converts between 48 and 44.1 kHz sample rates
* Converts between SPDIF (coax or optical), AES/EBU, and ADAT
I think I purchased it originally so I could add an SPDIF input to a soundcard that only had ADAT input, but ended up with a soundcard that had SPDIF input anyway.
Or if you have a need to convert between physical formats at 44.1 kHz (e.g. optical to coax or vice versa), this could be just the tool for the job. I haven't tested every possible combination, but if you have a specific thing that you think this would do for you, let me know and I'll see if I can test that.
Bottom panel is a bit scungy, top panel is fine though.
