A-50DA


A-50DA

Pure Audio Full Amplifier/Converter with 2x90 Watts, Phono and asynchronous USB Digital Input
Open to all possibilities The A-50DA is open to all current end music formats Its high-grade phono input deals with the signals from record players, while four golden cinch inputs are ready for all types of Players. Digital formats are dealt with by a highly modern D/A converter based on the ESS SABRE Ultra. Via asynchronous USB transfer this converter also supports ultra-high-resolution material with 32 bit and up to a sampling rate of 384 kHz, as well as native DSD with up to four times the rate (11.2 MHz). The switch output stages in the A-50DA specially developed for use with music supply 90 watts per channel; a mains transformer of large dimensions with separate windings for the power amplifier, pre-amplifier and controls ensure a stable feed, including with highly-dynamic encoded material. A thick aluminium front panel, metal knobs, massive screw terminals and, last but not least, a high-grade remote control ensure that everyday use of the A-50DA will provide as much enjoyment as its sound.


 Connectez votre ordinateur directement à l’entrée asynchrone USB. Le transformateur D/A ESS ES9016S intégré traite les signaux lui-même avec la plus haute résolution possible, comme Quad-DSD avec jusqu’à 11,2 MHz et les fichiers PCM dans le format WAV ou FLAC avec jusqu’à 384 kHz et 32 bit.


 The highly-efficient MOSFET Class D amplifier supplies 90 watts per channel and facilitates extremely dynamic, detailed and precise sound reproduction.






Connect your record player very easily to the phono input using an MM or MC system and enjoy your vinyl collection in the best quality.
