Hi!
I'm wondering to make this:
- 2 analogue inputs followed by CS5396-KS and CS8404A to make a ADC at 24bit/96kHz;
- 4 coaxial digital inputs;
- 2 optical inputs;
- Digital filter;
- Digital switcher;
- 1 coaxial digital output;
- 1 optical output;
- 1 analogue stereo audio output using Cristal components and a famous TDA.
All this in a nice aluminium chassis, like the Chord.
Now, the problems are right here:
- I've received the samples and some of them are SMD. How can I Convert them into normal DIL?
- What can I use to make the digital input shitch?
The volume control will be a PGA2310PA (and a PIC, of course!).
Thanks in advance for some advices (don't tell me not to do this!!)

An externally hosted image should be here but it was not working when we last tested it.

Many thanks for the link...
Translation, please!!
I've emailed them for a contact.
Nice adaptors😉

Digital Pre-amp
Hi,
Why not use the original SMDevices directly?? After all, these are some state-of-the-art devices, and not using a dedicated PCB may degrade "System Performance"
😉
Can u make such? Or here the problem is?
I thought about a closer design, therefore I'm writing this, but I prefer the downstated cofiguration:
- CS5394 or CS5396 ADC with several Analog inputs, relay switched.
- some 5-8 digital inputs /TOSLINK and COAX/
- 3 SPDIF receivers and digital switches / multiplexers
- at least 6 ch of DACs, 2 of them state-of-the-art sigma-deltas from AD, TI, AKM, Crystal - 2 for stereo, rest for surround;
- bass re-direction - analog - trough the front's
- Digital Volume Control, maybe with a relay-driven ext. 10-20dB attenuator
- microcontroller and display
- maybe SRC
This enables Surround Sound D to A conversion, using for example 6ch SPDIF outputs on some Creative Live 5.1 / Audigy card. A DSP can also be added.
My Problems : 🙂 I can not program DSP's yet, also I can't do Micro's; But it's not that hard and it will be AN UPGRADEABLE Pre-amp
