ADAT and optical SPDIF

    Please forgive my ignorance. A few years ago I jumped from analog to DAT recording, and now to HD. Never used ADAT, so I am wondering. What is the difference between ADAT light pipe standart and regular optical SPDIF, if any. If I have a converter with ADAT pipe output, can I connect it directly to optical SPDIF of let say CD burner, or through Sonic Solutions media converter to coax input?

    Thanks, Mark

    ADAT Optical, is a dedicated 8-channel Alesis designed audio protocol. S/PDIF is a 2-channel dedicated format. Many newer devices that use the ADAT optical also let you use 2-channels on that format to transfer S/PDIF data in or out.

    Most, if not all, CD recorders only accept S/PDIF for the optical option. If the device that has the ADAT optical can send 2-channels of S/PDIF format out the ADAT optical, then the CD recorder will be able to record it. Of course your CD recorder needs to see 44.1kHz unless it has SRC capability and if the source and or ADAT is sending valid 24-bit data, the CD recorder will only accept 16-bits of it.
