Thursday, January 10th, 2008

This is using PMD100 to replace SM5842 in D1Vx DAC.  The PMD100 can decode HDCD signal from CDs.

The input mode is right justified 16 bit and output is 20bit mode for PCM63.  All settings are hardwired and cannot be changed by jumpers!

Alesis AI-1 Sample converter

Wednesday, January 2nd, 2008

This is an old sample converter and digital selector for optical, SPDIF & AES formats.  The sample frequency can be selected for 44.1kHz or 48kHz.  Since this is old and you can get is as low as US$100 from ebay.

I use this to connect from my CD-PRO2 transport, SB3 or DAT as input and output to my D1V3, and other DAC or DAT.  This make my switching among equipment more easy.
