DigiKey stocks TORX connectors.


A switch would probably work fine. Might want to add a couple resistors to keep it clean.

Talking Working

Hi,

my two Opus arrived yesterday. Tonight I connected them to the two USB->I2S converters from DDAC (PCM2707 based), then to PC: both Opus are playing music now together with Foobar. Tomorrow I'll compare the Opus with my Wolfson 8740 evaluation board.

Interesting is that the two Opus can play together with Foobar (tried it in XP and Vista). The system detects both PCM2707 as "USB Audio Dac" and installs the drivers automatically. But you can't use two USB Audio Dac with Foobar directly.

First you must use ASIO4ALL asio driver. ASIO4ALL detects the two Dac and assigns two ASIO channels for each one for a total of four channels. When done, Foobar detects 4 independent outputs.

Bad news is that I'm not able to make work the Foobar DSP crossover plugin (http://xover.sourceforge.net/.)

Does it exist another DSP software or somebody can take a look to the Foobar plugin?


P.S.
The DDAC USB boards will go to my PC at work, so I'm still waiting for USB boards to be released by Twisted Pear to order together with a couple of Ballsie

Is there any place I can get the schematic for the old receiver board? Thanks

Default Wire gauge between IEC socket and Transformer?

I am planning on using a terminal block to connect the 2 transformers for my diy cd-player to the single IEC input socket. What gauge wire should I use between the 110v power input socket and the terminal strip?

Thank you
Darren

18-20ga should be just fine. At the currents the CDP or DAC will see anything more is overkill.

Is the Opus no longer available as a kit? Your site only shows assembled parts. I was suggesting it to a friend as a little first project but then I noticed no mention of a kit. Kind of sucks....

We no longer offer it as a kit. The reason is that we were pre-mounting the SMD parts (TSOP, very very small), but could not test them unless the rest of the board was built up.

The consensus from feedback (which we were surprised by) was that people preferred pre-assembled modules.

The new boards will be almost all surface mount parts, which would not make a very good first project.

FWIW: The power supplies will still be kits, and good for beginner builders.
