anyone know the a/d/a conversion time though a 800?
...I have a REALLY picky client.

    It's cryptically listed on the datasheet.
    http://www.bssaudio.com/product_downloads/Datasheets/BSSBLU800DataSheet.pdf

    It's listed as 38.7/Fs and 28/Fs. Don't ask me why the datasheet doesn't just list milliseconds. At a guess, I'd say that engineering wrote down \"38.7/Fs\" and whoever wrote the datasheet didn't know what it meant so they just copied it.

    In any case, analog input A/D is 38.7 samples. That's .80625ms at 48k. Analog output D/A is 28 samples. That's .58333ms at 48k. The total of those two would be 1.389583ms at 48k.

    Assuming the speed of sound is 1116.3969 feet per second, then that's the time it takes for sound to travel 1.55 feet or .4728 meters or .00235 furlongs or .2586 fathoms or .9866 roman cubits or about 1.034 biblical cubits. I think we should have that on the spec sheet.

    Thanks Dan. Short enough for me, and hopefully for my picky client who says he can hear 1ms delay. Makes it tough to use anything digital at all...
    ....yes, Cubits....have to start using that reference.

    Sorry to hear that you're working with a lunatic.

    Is this a bad place to point out that 19\" (the width of the rack space occupied by your BLU-800) is 1.05 biblical cubits? This means it actually takes LESS time for the signal to process through the soundweb than it would take for sound to traverse the same distance. It gets worse if you add the full width of the rack....Also if you can run it at 96k, you can halve that time, so it takes twice as long for sound to traverse the device as for the signal to process... :twisted:

    Believe me, I understand the irony here....if you knew more about this client, whom I am not at liberty to disclose, you'd either understand better or think it even more ironic.

    ok... now I can't stop laughing.
