Default ADAT Format

Can someone pl explain the differences between SPDIF and ADAT optical for single lightpipe connection? Are they interchangeable and what does it take to convert

ADAT is 8ch and up. SPDIF, at least in its IEC60958 mode, is 2ch.

ADAT is a multitrack format.
I beleive it sends all tracks down the same pipe, so you'll need a box. But that's what you were asking wasn't it
What's in the box....?

ADAT is an 8 channel format invented by Alesis to transmit 8 channels of digital audio down a single piece of fiber. They used the TOSLINK connector because it was already readily available and they didn't have to design something new. SPDIF is the Sony/Phillips Digital InterFace. It transmits two channels of digital audio and time code. If you want to connect your system using ADAT, you will need to use an interface box to split the eight channels out to separate jacks. There are a few of them in the pro-audio world to choose from. If I recall, Tascam makes a pretty good one.

Cheers,
Zach

I have a Fostex Cop-something that takes SP-DIF & ADAT from optical to coax(RCA) or XLR

I'll try. I have bought an A/D convertor that outputs ADAT or aes/ebu. I would like to convert the ADAT signal to spdif optical/electrical. In prefer to leave the aes/ebu output as is.
