My new 1545-cs8414 nos DAC

[Algar_emi]

Hi. Here one of my current project. A small none-oversampling DAC using the 1545 DAC and CS8414 receiver. It is running on battery and has class-A op-amp outputs, local regulators and BG caps.

It has Scientific Conversion high bandwidth dual primaries transformer. This transfo offer the 110 ohms AES/EBU and 75 ohms SPDIF dual inputs.

I did 2 versions of PCB. The second version has balanced outputs in addition to single-ended. It is using the BB DRV134 IC's for balanced conversion. The second version is also using 4 batteries for full dual mono power supply.

Here the version 1 PCB. It is using AN8005 SMD regulators.

It is a collection of differents ideas, some from the dAck! DAC, some from the Scientific Conversion white papers and some articles on the net. PCB desing are from me.

Here a summary of the features and specs.

I'm building the enclosure for the version 1. Here the back panel.
It has the battery charger input connector, the AES/EBU Neutrik and true 75 ohms Amphenol insulated BNC digital inputs and Cardas RCA audio outputs connectors.

They are mounted on 1/8" alu plate.

The front panel that I just completed. It is a double plates construction (I'm using a recycled very nice and strong alu enclosure). Using this assembly, I was able to hide most of the drill holes and mounting hardware, only showing 4 nice little stainless steel hex screws.

The Front plate is from a nice aluminium Hayes modem casing. It is already anodized and well finished and the grooves give some look. I used the same trick for the faceplate of my Aleph30.

We can see the power switch (On-Off-Charge) and the two leds, Power On (Blue) and Sync (Green). The leds are recessed and shown throught small pin holes. We see only a small slot for the switch.

Not too bad I think

Very nice!

Hi, I cannot open the file as it seems not to be a valid Winzip file.

It is a plain text file. I have no trouble opening it.

Windoz huh......
This file has a zip extension so this stupid PC tries Winzip.......

It had no file extension when I tried downloading, so I just gave it a .txt extension -- I assumed that's what he'd be sending
