[PCI Rec Card][Alex Sloley's Digital Audio Card Overview]

Note:

I have no other relation to Elrad than as a satisfied user of their Digital Audio Cards.
By the way, if you main interest is digital in only, a Ensoniq Audio PCI or a Turtle Beach Montego both have a feature plug, to which you could connect a S/P-DIF interface. More info at my links page. 

Another Note:

The ftp archive of Heise Verlag, the old publisher of Elrad no longer carries the driver software for this card. This could mean the board and GAL's are unavailable too. Please contact www.emedia.de for more info on this.

Take five optical digital interface card

Take five is a digital audio interface card for the pc. The card supports 32, 44.1 and 48 kHz datarates. There are two optical inputs and an optical output available. Below is one of the scanned pages from the German ELRAD magazine of August 1994. I asked and got permission to use this material.

Elrad published this card as a D.I.Y. project, but you can also order it prebuild. Thanks to Teemu Mottonen for the following info:

He (Andreas Spoo) has a small company, called AS Ware. His fax number is the same
as the phone (+49 221 138596, from outside Germany). The card price
is 450 DM, plus shipping (about 10 DM within EU). That includes the card,
two optical cables and 6 month warranty. I forgot to ask about payment
options (so no idea about Visa). 450 DM is about 270US$, not bad if
a self-made version would be $200.

I also got email from ELRAD, saying that photocopies of the article
can be ordered, the cost is 5 DM (payment on an Eurocheque). But I think
I will order the readymade card.
The $200 or fl.550,- is what it has cost me to build the board myself.

This is a scan of the article as it appeared in the Elrad of August 1994.


Due to space problems I took the scans offline.

You can order the board and the GAL's via www.emedia.de

Notes on getting the parts

The Yamaha YM3437 was a difficult part to get. It is only needed if you want to use the optical output. I found it as a replacement part for Yamaha keyboards. Contact your local Yamaha repair centre for replacement part: XM530A00. Alas this is a SMD part, but the pin-layout is the same. Just wire it one-to-one on a DIL socket.

The FIFO's are made by Dallas Semiconductor. See their Distributers list for a local distributor.

The oscillators are made by Seiko. See their Distributers list for a local distributor.

As far as I know, there are no Windows 2000 or Windows XP drivers for the Take Five card. One could derive one from the Linux source code, but this requires Windows 2000 driver knowledge. Hiring a programmer is probably more expensive than a new card (with driver).
