How to: UA5 digi mod
« on: August 05, 2003, 11:25:52 AM »
Stock Edirol UA5s cannot output standlone digital signals via coax/optical - these outputs are active only if a PC is connected to the UA5 via USB.

A simple modification enables standalone digital output via coax/optical without the need for a PC to be connected via USB.

Thanks to David Klein for the write-up!

Alternatively, the Oade Bros and Busman Audio offer this mod as an option on UA5s they sell.  They also preamp mods, too.  Check their websites for more info.

You got any more pics of the VU meters?  Did you ever get it into the project box?

Digital Chips used in UA5

From the man himself.

http://www.oade.com/Tapers_Section/Forum/dcboard.php?az=show_mesg&forum=105&topic_id=195&mesg_id=195&page=




           Hi !
I get asked this a lot, so here is some useful info on the UA5's digital circuits.
The USB controller is the TUSB3200, the digital I/O chip is the Crystal CS8420, this one does I/O and SRC as well as SCMS. I have not tried this, but the 8420s spec sheet indicates it ignores SCMS if the Pro bit is set, if you have tried it, let us know. It also supports digital I/O without SRC. The power ICs are BP5220 for + 5v , NJM2360 for -5v and NJM2374AM for +48 volts (10 ma max).
I hope this helps...Doug

Just wanted to say that you have to REEEEAAAALLLY hack at the wire to break the continuity after R8.  I wound up just taking off that reisistor, which naturally breaks the circuit and works well.  Just thought I'd pass it along in case anyone else runs into trouble cutting the board.

FWIW
 I agree taking off the R8 resistor is the way to go unless you are looking into making the UA5 stock again. If so keep the R8 resistor in a safe place because that thing is tiny!!!

All the DIY links for the straight digimod appear to have dried up.

Anyone know of any current links?

Is the trace cut on the switchable option instructions the original digimod?

Remove or lift R8, then install a jumper wire as shown in this "Edirol UA-5 with standalone AD modification" link.

Another how to link, it's missing one photo but reproduces David's write up.

you will need FINE pc wire to do the jumper.I used a pro-soldering station used glasses to veiw work.Removed the transistor from the board and jumped the wire according to directions. make sure your soldiering is very clean and perfect.Too much heat on the board will fry components so you have to be careful and understand what your doing.its a very simple MOD it took me abot 30 mins from start to finish checking my work as I went.I know there is a new mod somewhere that does not kill the USB input

Wire-Wrapping wire works great for the jumper, available from your local Radio Shack.
