Atoll Electronique CD50 Evolution silver

Atoll CD50 EVO: The Next-Generation High-Fidelity CD Player

The Atoll CD50 EVO CD player is equipped with the TEAC CD-5020B mechanism, renowned for its superior reading quality. This mechanism offers a new data addressing system, ensuring optimal precision when playing your discs. Whether you’re listening to classic audio CDs, CD-Rs, or CD-RWs, the CD50 EVO guarantees faithful and detailed sound reproduction.

Carefully Designed Power Supply for Exemplary Stability

Atoll has paid special attention to the power supply of the CD50 EVO. The player features 8 regulated power supplies dedicated to enhancing the stability of the converters. A 1.6 VA transformer is specifically dedicated to low consumption, ensuring clean and stable power for all components. With a total capacity of 16,700 µF, the CD50 EVO provides substantial energy reserves for dynamic and precise playback.

High-Performance Output Stages

The output stages of the CD50 EVO are designed to deliver pure and detailed sound. They use a differential architecture with discrete components, polarized in class A. The direct current coupling, without coupling capacitors, ensures optimal signal transparency. The current/voltage converters with bipolar transistors contribute to natural and musical sound reproduction.

Extensive Compatibility and Versatility

The CD50 EVO is compatible with a wide range of discs and formats. In addition to classic audio CDs, it supports the playback of CD-R and CD-RW. It is also capable of playing digital audio files in MP3, WMA, and AAC formats, offering you increased versatility in your choice of music sources.

A High-End Digital-to-Analog Converter

At the heart of the CD50 EVO is the Texas Instruments PCM 1791A digital-to-analog converter. This 24-bit/192 kHz converter offers exceptional resolution and extended dynamics. With a signal-to-noise ratio of 113 dB and distortion below 0.001% at 1 kHz, it guarantees sound reproduction of great purity and remarkable fidelity.

Impressive Sound Performance

The CD50 EVO stands out for its high-level sound performance. With an output level of 2.5 Vrms and a bandwidth of 5 to 20 kHz, it offers balanced and detailed reproduction across the entire audible spectrum. The 2 µs rise time ensures excellent responsiveness and high precision in transients.

Optional Digital Card for Even More Possibilities

For enthusiasts of external digital sources, the CD50 EVO offers an optional digital card. This card adds a coaxial input (24-bit/192 kHz), an optical input (24-bit/192 kHz), and a USB-B input. The XMOS USB interface, with a program specifically developed for Atoll, allows the playback of PCM streams from 16-bit to 24-bit up to 192 kHz in asynchronous mode. This option opens up new listening and connectivity possibilities.

Elegant and Functional Design

The CD50 EVO boasts a sleek and elegant design. With dimensions of 440 x 280 x 95 mm and a weight of 6 kg, it integrates harmoniously into your hi-fi system. The front panel is available in aluminum or black finish, adapting to your aesthetic preferences. The provided remote control allows you to easily control all the functions of the player.

Is the CD50 EVO compatible with SACD discs?

No, the CD50 EVO is not compatible with the SACD format. It plays standard audio CDs, CD-Rs, CD-RWs, and digital audio files in MP3, WMA, and AAC formats.

Can I use the CD50 EVO as an external digital-to-analog converter (DAC)?

Yes, with the digital card option, the CD50 EVO can be used as an external DAC. The card adds coaxial, optical, and USB-B digital inputs, allowing you to connect external digital sources and benefit from the CD50 EVO’s conversion quality.

What are the advantages of the TEAC CD-5020B mechanism used in the CD50 EVO?

The TEAC CD-5020B mechanism offers superior playback quality thanks to a new data addressing system. It ensures optimal precision when reading discs, guaranteeing faithful and detailed sound reproduction.

Is the CD50 EVO manufactured in France?

Yes, the CD50 EVO is proudly manufactured in France by Atoll Electronique. The design and assembly are carried out in Atoll’s workshops, ensuring rigorous quality control and meticulous attention to every detail.
