Blanced passive output stage for the Behringer DCX2496

décembre 2005

Direct output

balanced version

Before you start go and do some shopping

To set this up you will need :

12 x 2.2nF styroflex capacitors
12 x 1% 1kOhm MRS25 precision resistors
12 x 4,7µF/250v polypropylene capacitors (SCR ref. PA470 are really good but any good polypro will do).
1 x test circuit boards 100x160mm
fixture hardware (screws etc..)
some thermal sleeve

Schéma :

Connections :same as unbalanced version , except that you will be using both AOUT+ et AOUT- outputs from the digital to analog AK4394 converters. See diagram below and find corresponding pins in the 26 pins connector :

Other difference resides in an increased by 3dB output voltage : 5V peak to peak instead of 2,5V
