Hi Bernardo,
The menu change is easy.
-Press the arrow keys together to enter setup mode.
-Hit the up arrow twice to get to Setup 105 [shown as 105doF on the display)
- If the last set of numbers is 01, you are already set to output spdif.
- If not, hit the Merk/Set key so the 00 is flashing, hit either arrow
key to make it 01
- Hit mark set and then Disp/Quit to exit setup mode and you are done.
I would assume that you can just use pin 2 for the hot and pin 1 ground
for an unbalanced cable, just like any other xlr - rca. Cable should be
110 ohm, but I have been told that for short runs it really doesn't matter.
Hope this helps,
---Matt

I think it's 75 ohm cable

Thanks guys,
So,...i believe any normal XLR to RCA adapter will do it, right?
Can i just plug in one of my short XLR cables with an rca adapter?
thatīs nice...
75 ohms is for video cables.
digital are 110 ohm, and i also think i heard that for short runs itīs
not a big issue.
thanks and regards,

AES/EBU to Spdif
Group: rec.arts.movies.production.sound Date: Thu, Jan 1, 2004, 8:49pm
(EST-3) From: bernardosix DeleteThis @yahoo.com (Bernardo Six Costa)
Hi,
I need to make a digital output from my PD4 into an spdif input. I know
i have to change the PD4īs menu.
Can someone check with me the pinnages on the cable? (XLR to RCA)
Itīs 110ohm cable,right? recomendations?
regards,
Happy new year for us all!

Idealy you should use a 110 to 75 ohm transformer. In any event do not
use star quad cable for the connection.

Skivvy:
AES/EBU is 110-ohm balanced, 5v pp squarewave. You can get by with mic
cable for short runs, but proper digital ("purple") cable is a heck of a
lot better and not very expensive. In fact, good Cat5e is a better match
than most mic cables.
s/pdif is 75-ohm unbalanced, .5v pp squarewave. Normal video cable (RG-59)
is ideal, and many facilities crimp RCA<>BNC adapters onto the devices and
then wire the stuff like video. But even Radio Shack RCA-RCA video cables
will work.
Connnecting an AES/EBU source to an s/pdif input requires a simple pad to
condition both the voltage and the impedance:
XLR pin 2 goes to 94 ohms, then to 58 ohms, then to pin of RCA or BNC.
18 ohm resistor goes from junction of two r's above, to ground. Ground
goes to sleeve of RCA or BNC.
Depending on the output circuit, either XLR pins 3 and 1 or just XLR pin 1
goes to ground as well. Many AES/EBU outputs use small pulse transformers
to drive the line, so pin 3 completes the circuit. But if it's a pair of
op-amps out driving the line, you can let pin 3 float.
Obviously, this circuit won't take you from an s/pdif output to an AES/EBU
input.
As far as the bitstream, they're often called 'professional' and
'consumer'... and either can live on either electrical standard. But most
devices these days will recognize them interchangeably.

Im not sure, but i believe i 've read some article ( 10 years ago ,
when i visited the Nagra factory in Switserland ) that AES is an
absolute different protocol than SPDIF.

SP/Dif is really only an "unbalanced" version of AES

Bernardo,
Happy new year! A couple of years ago I created a setup chart for the
PD-4 with all the setup options, along with their defaults, listed on
one, easy-to-read chart. Coffey Sound has it available on their web
site at www.coffeysound.com. Click on "Community" and then click on
"Gear Manuals" and you'll see "Fostex PD-4 Setup Modes". It's a PDF
(Adobe Acrobat) file that you can download and print out.
One option is to print it, fold it in half, and laminate it. That makes
it really handy to store and to use.

Assuming you can ignore the level, impedance, and
a few bitstream differences, that is. >> Stay informed about: AES/EBU to Spdif |

Well, there's also a 20 dB voltage difference and a different impedance -
and up in those megahertz ranges, impedance can be important.

so it's not just the unbalanced version ?

It -is- the unbalanced version. At a different voltage and impedance. And
if you're talking 'pro' vs 'consumer', with a few minor bitstream
differences.
The first Ethernet cables were unbalanced. The ones everybody uses now are
balanced. But you can't get from one to the other with a simple adapter.

So, if i make a simple Bal to unbal cable, it works..?
