BEYER - A20 - Amplificateur de casque pour système audiophile

Fabriqué en aluminium brossé, le boîtier de l‘A20 est particulièrement solide et sans résonance. En raison de la conception du châssis innovant, les vis ne sont pas visibles sur les surfaces externes. Equipé d‘un potentiomètre ALPS original pour le contrôle du volume variable, un bouton en aluminium complète le look attrayant et robuste de cet amplificateur.

Avec une entrée RCA à gain élevé, l‘A20 œuvre facilement avec la plupart des sources. Grâce à l‘alimentation intégrée, qui est reliée par un cordon d‘alimentation amovible (fourni), aucune alimentation externe n‘est nécessaire évitant ainsi le dérangeant bruit de fond. Grâce aux deux prises casque en face avant, deux personnes peuvent écouter le A20 ensemble sans un adaptateur de câble.

Points forts :

• Réponse en fréquence ultra-linéaire
• Impédance maximale pour casques de 30 à 600 Ohms

BEYER - A20 - headphone amplifier

With the A 20 you will rediscover your dynamic headphones.

This new headphone amplifier from beyerdynamic is perfect for all headphone applications and provides dual outputs for shared listening with a partner.

Superior Sound

The circuit of the A20 is designed based on our legendary A 1 reference headphone amplifier. The discrete output stage provides plenty of power even for  high-impedance headphones while the dynamic, open and precise sound sets the A 20 apart from what can be found in the normal output stages of  regular amplifiers or receivers. This is confirmed by its first-class circuitry and excellent technical specifications that provide a balanced sound for long periods of comfortable listening.

High build-quality and nice looks

Made of brushed aluminum, the housing of the A 20 is especially solid and resonance-free. Due to the innovative chassis design, no screws are visible on the external surfaces. Equipped with an original ALPS potentiometer for variable volume control, a knob turned from solid aluminum completes the attractive yet robust look of this amplifier.

Simple and Flexible

With a high-gain RCA input, the A 20 works easily with most sources. The input signal can be looped through and is entirely free from signal-loss thanks to the hard-wired RCA output. Due to the built-in power supply, which is connected via a detachable power cord (supplied), no external power supply is needed avoiding disturbing background noise. Thanks to the dual headphone jacks on the front, two people can listen to the A 20 together without an adapter cable.

• Two 6.35 mm headphone outputs
• Elegant and solid all-metal housing
• Particularly open, transparent sound
• Also suitable for 600 Ohms headphones
