PT AND ADAT

I am not familiar with ADAT, but am wondering if I use a preamp with an ADAT output into PT ADAT in, can I use the preamps as seperate channels recorded to seperate tracks?

ie 16 drum inputs going to 16 seperate tracks on my 002.?

Yes sir, you sure can. That would be 8 Channels at a time. After hooking up the unit of your choice, just select the corresponding ADAT channel in your PT input assignment.

ok so lemme just make sure i'm 100% understanding here. If I use my 002's 8 analog inputs thats 8 seperated channels of input, and the and then using 8 channels of an adat preamp connected out via 1 lightpipe, i get 8 more channels , and 16 simultaneous channels of seperate input?


How does ADAT lightpipe handle this? does the F/O split the signal as 8? and is there any drawbacks to this?


thanks for the replies

The only drawback is that ADAT tops out at 48kHz whereas PTLE is 96kHz capable. If you don't care, it doesn't matter.

I use a Rosetta 800 A/D and D/A converter that talks to the 002 via ADAT and it works beautifully, every day. You'd never know that signal's passing thru an 002 and that's exactly where I want to be.

What max said... and another 2 channels if you decide to use S/PDIF as well.

Yes, that's exactly what the lightpipe does. How's it do it? I don't know. Magic?


Ain't life grand?

I think it multiplies signals by whatever number is necessary to make them light, then it passes the light thru the optical cable, the it divides by the same number and voila! They're audio again!



Science rocks, dude!

The ADAT signal is time-multiplexed, like the time-multiplexing of two-channel audio over SP/DIF only with more channels. There's no degradation of data; it's lossless barring problems with the cabling, etc.
