DIGICODE 2.24 & DIGICODE S192
Tube analog dac 24 bit dual mono 96 khz, Full Balanced input /output. The Digicode 2.24 has implemented four dual mono 24 bit D to A multi bit converter (no economical sigma-delta dac) with tube analog output stage as full real balanced. The four dac works as differential mode so the balance signals are generated since from digital source. We have set-up by trimmer the critical single MSB on DAC for obtain highest real resolution . With special digital filter is possible to choice the right number of coefficients and slope for better listening choice as sound preference. The analog output section uses selected 4 double triodes in pure class A ( 4 tubes ECC-81 or 12AT7) . Tubes are selected for lowest noise and tuning trimmered for precision voltage output. The conscruction of Digicode is modular: with three removable cards is easily replaceable in case of future upgrading for new technologies the individual form. A separate power supplu unit reduce the noise floor and magnetic influence to the circuit. A digital circuit with recovey double PLL oscillator supply stable and precision LOCK-ON with perfect matching with our Digidrive CD-Transport.

• Ceramic gold plated noval tube sockets
• Digital input transformer hi-speed, hi-flux
• Selected DAC 24 bit as multibit multilevel design
• Toroidal power low flux lose transformer
• USB 2.0 digital input full compatibilitywith PC Win or Mac OSX
DIGICODE S192
The new Digicode S-192 digital tube D to A converter is based on R2R the hi performances dac from BB PCM1704, high-resolution dac, output circuits is design around vacuum tube type miniwatt as ECC-81/12AT7.
Balanced analog output as real design with four dac and four analog stages.
Digital signals are accepted up to 192 kHz 24-bit on all inputs, USB input too.
The Digicode S-192 is also equipped with word clock input and digital spdif output for general purpose application.
