Non oversampling DAC
Ergo,
Can this schematic be used with the 1704 DACs? I would like to listen to 24 bit sources, both 96K and 192K without oversampling. By the way, paralleling the DACs will give you twice the current out and with the same resistor value will then give twice the voltage out. It just plain sounds better to parallel. Have done it many times. Going from one to two devices give the most difference, but going to four stacked is even slightly better.

Non-oversampling Marantz CD4000 (philips CD713/723)
Ergo mentioned that the Marantz CD4000 in non-os mode was achievable if you could control the SAA7378 where the 4 times oversampling is done.
I have downloaded software from www.daisy-laser.com which should allow a PC to communicate via DSA protocol with SAA7378 - but I have not got it working yet - the software seems to work ok but I suspect that my cable connections are wrong - anybody tried this already?

Can you be more specific where you found that file? This is what I have been looking for in a while. I suspect it would work for most CD7 and CD10 series decoders...

The link is

or the file itself

I also tried a few hours ago and the tech2b.htm didn't show up. Now it does. So it seems it was a temporary problem.

non-os marantz cd4000
Hi all,
There seems to be an intermittent problem with this site http://www.daisy-laser.com. I will try to post the zip file here. Let me know how you get on - I keep getting incorrect number of bits. thought it was the cabling but I have just looked at documentation that comes with the prog and the problem might be that prog expects 16 bit communication and SAA7378 works with 18 bits in some cases ? Don't know will have to investigate further.
Oops just tried to send attachment - it is too big I will break it down- her's the main part - DSA.ZIP

CD4000 no-os
The following pdf file (oops couldn't attach this file - too big) - URL - http://www.daisy-laser.com/downloads/products/CD/modules/anslmk39901.pdf
describes how with the use of eprom and microcontroller the DAC format can be set using four pins (this would be very useful for A-B sonic comparisons of os & non os )
Also the current DAC format diplayed if PLAY & STOP keys are pressed at powerup - I tried this with my CD4000 but nothing.
It appears that the display electronics used in CD4000 is a 64
pin chip with the following marks CD723V8403 and 87CM71E-6872.
Anybody know what this is?
Another way to get the functionality is to buy the display module form daisy-laser.com. Two problems though - it costs nearly as much as the CDP itself I believe if you look at a sister site http://www.daisy-laser.nl/homeoptics/ - €72 for completed board + €28 shipping
second problem - the buttons will almost deinetly not match the holes in the CD400 facia - so new facia panel.
Too costly - too messy - easier to build a non-os DAC from scratch.
Still its tempting - NO?

DSA control software
Ergo, Capslock
Any feedback? - did u get the DSA.EXE communicating with your SAA chip? If so -let me know what I am doing wrong - I get invalid bitcount when issuing a DSA command over the same line as microcontroller If u didn't get it to work - Lets discuss the problems and see if between us we can't sort it out.

jkeny, I can't actually try it right away as I don't own a CD4000. I have repaired some of them and that what gave me the idea... If I get a unit in for repair, I will try it. There is just a small problem - one never knows when that will happen : )

hi,
i know this is an old thread, but can anyone of you help me out with the schematics for the cd610?
