Description
Atoll CD400 Evolution
The Atoll CD400 Evolution is a genuine high-end audiophile CD player that will bring the best out of any compact disc! Hand-built by experts in Normandy, Northern France – it offers superlative audiophile performance
The Atoll CD400 Evolution has a chassis made of massive aluminium sides that ensure perfect mechanical inertia. In addition, the original shape has been studied to absorb better all vibrations. The top loading drive specifically developed for the 400 line consists of mechanical elements in steel and aluminium treated against vibrations, decoupled from the frame of the device by four metal spacers. This greatly enhances the accuracy of the laser and the error correction circuits. This construction greatly improves the musical timbres and treble reproduction.
- 10 mm brushed, micro-blasted and anodised aluminium front panel, high-precision engraving.
- 2 mm steel chassis.
- Solid aluminium sides.
- New top-loading mechanics developed by ATOLL, suspension mounting, solid aluminum platter.
- Two 10 VA toroidal transformers each for the audio stages.
- 30 VA linear transformer (general power supply).
- 1.6 VA linear transformer (control logic).
- Ten regulated and independent power supplies.
- High-quality MKP link capacitors.
- Anti-vibration system.
- Complete dual mono structure:
– Two independent symmetrical stages for each channel.
– One PCM1792A converter per channel. - Bipolar transistor audio stages have a perfectly symmetrical structure, are polarized in class A, and are without feedback.
- Transistor and LED current sources ensure perfect stability and drastic rejection of distortions.
- Converter inputs: coaxial, optical and USB.
- High-contrast OLED display (on or off mode after 5 seconds of inactivity).
- CD text display.
- ATOLL global remote control supplied as standard.
