Didelė kokybė, kaip ir svoris
The A-70DA, which weighs more than 17 kilos, is not just about mass, it is above all about class: Separate mains transformers for pre-amplifier and amplifier sections, above all when they are individually cast and shielded as here, provide not only weight, but also working conditions with unsurpassed low interference for the audio circuitry. The doubled A-70DA is worth it because its pre-amplifier has a completely symmetrical layout. An individual, particularly low-loss loudspeaker volume control was even integrated for the symmetrical XLR input. Via its digital inputs the A-70DA is equipped for all modern music formats. In this respect, the very highest resolutions, such as Quad-DSD (11.2 MHz) and PCM with 384 kHz and 32 bit, are supported via USB. The high-resolution counterparts in the analog world are exclusive MC pick-ups which, thanks to the a switchable phono stage, supply this top model just as precisely as the widespread MM systems. With its doubled chassis, the full-metal loudspeaker knob and the thick aluminium front and side panels, the casing guarantees a suitably high-class performance.
Grok aukštos kokybės garso takelius
Connect your computer directly via the asynchronous USB port. The integrated ESS ES9016S D/A converter processes signals itself with top resolution types such as Quad DSD with up to 11.2 megahertz, and PCM files in WAV or FLAC format with up to 384 kilohertz and 32 bit.
Jokio šanso problemoms
The three-part chassis effectively shields the power supply, pre-amplifiers and power amplifiers and avoids mutual interference. A fully symmetrical pre-amplifier circuit and symmetrical Neutrik XLR ports achieve the best possible signal-to-noise ratio. XLR connections are standard in the area of studio engineering and much less prone to any kind of interference.
Efektyvi amplifikacija
The highly-efficient MOSFET Class D amplifier supplies 90 watts per channel and facilitates extremely dynamic, detailed and precise sound reproduction.
Tobula vinilinių plokštelių mėgėjams
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.
Simetriškas sujungimas
The A- 70DA is equipped with a Neutrik 3-pin XLR input. Thanks to the fully balanced preamplifier XLR connection guarantees maximum sound quality, for example in interaction with the network players N-70A or the Universal Player BDP-LX88.
