Default Add Coax Out to M-Audio Transit?

I'm looking for as much detail as possible describing how to add a coax out (or replace Toslink) to an M-Audio Transit. I would also be interested in any other succesful modifications ala Emperical Audio's mods.

If you instal a Tent Labs XO3 clock, not only will you get a vast improvement in sound quality, it also has a very good digital coax output built into the board, so you'll get the best of both worlds.

Cheers George

Forget what I said, I thought you misspelt transport, I just saw what a M-Audio Transit is, and it will never fit.

Cheers George

Those will work, but they all suffer from the same mistakes. There are better examples on this forum.

Hello Jocko,

Do you mean a circuit like this from the NEC 602 thread?

http://www.diyaudio.com/forums/showt...489#post594489

The other information I would need is to know where I can tap the TTL signal from the M-Audio Transit.

Thanks,
Johan

On the input-pin of the optical transmitter

I never tried using any RS-422 TX parts. Seems odd to have an inverted output available, and not use it.........

Anyway, the drawback to using both the inverted and non-inverted ooutputs is that there may well be some prop delay in one of them. Unless they are perfectly aligned, don't use them. I have yet to see a F-F where they are, but I see people trying to use both together all the time.

I notice that the output Z of the 2 outputs is not identical, so that may be a clue.

Jocko

I used a simple resistor divider on the input signal of the optical output which works like a charm (don't remember the exact values anymore but i think 300&75 ohms or so will be ok).

Actually, I removed the useless analog output part of the transit to route the 'coaxial' spdif through the 3.5mm jack
