FEATURES:
High end digital controlled pre-amplifier.
The volume chip and controllers powered by 3 independently regulated supplies.
Starget capacitors used in the power section.
Remote control of volume and inputs.
4 hermetically sealed relay switched inputs.
LED display of inputs and volume.
High quality pcb.
Solid aluminium case front.
Gold sockets.
This is a high end, low noise pre-amp that uses a CS3310 digital attenuator from Crystal semiconductors, avoiding the losses and channel imbalance inherent in standard volume controls.
The CS3310 is a complete stereo digital volume control featuring a 16-bit serial interface that controls two independent, low distortion audio channels.
The CS3310 includes an array of well-matched resistors and a low noise active output stage that is capable of driving a 600 W load. A total adjustable range of 127 dB,
in 0.5 dB steps, is achieved through 95.5 dB of attenuation and 31.5 dB of gain.
4 relays switch in the inputs for the minimum loss of signal. . The advantage is that there are no parts to wear or oxidize as the relays are sealed.

Les autres pré m'ayant fait honneur dans mon salon et ayant servi de près ou de loin aux comparatifs :
- Audiofolia Farfadet
- Yves Cochet P3 que je possède toujours
Peut-être bientôt d'autres, pas vrai Benoît ?
A+
