Twisted Pear TXD wiring

larryg · 16th March 2010, 06:20 PM

Greetings, I need wiring info on the TXD module. This is for balanced operation,2 boards. I also have the Darwin selector,2 boards, the Joshua Tree attenuator,2 boards, etc. Can anyone help me?

There is TXD documentation available on the TP forums, Twisted X Driver/Preamp - Twisted Pear Audio Support

Thanks Paul. I have another question about SE to Balanced. As I see it, with the JT and Darwin, and the TXD having two boards each, does each board carry half the imput signal? If so, does the TXD boards carry the signal to the output?
Thanks,

Balanced signals have a 'hot' and a 'cold'. Each needs to be switched and attenuated individually, hence the dual boards for JT and Darwin when running balanced. The TXD is a balanced in-balanced out amplifier. I'd put them on the output, perhaps configured for some gain, depending on your sources and power amps.

You can run single ended inputs into a TXD by connecting the 'cold' or negative input to 0v. The output will be converted to balanced. This is how I used to run mine, but I never got around to the balanced JT and Darwin which remain in a box, a Buffalo now does everything. Such is progress.
