The audiophile headphone amplifier offers a natural and brilliant sound and can operate up to two headphones. Because the two headphone outputs are switched in parallel, the connected headphones should have the same nominal impedance of between 16 and 600 ohms. Introduction: "Live sound experience Whether you’re sitting at your computer or relaxing in your living room, a good set of headphones requires a suitable partner in order to truly reach its ultimate sound potential. Using standard headphone outputs on PCs or CD players greatly reduces the quality of your acoustic experience. Users of high-quality headphones benefit from greatly increased dynamics and precision with a headphone amplifier. The ultimate amplifier The A 2 is the ultimate amplifier for the world’s best headphones. The A 2 impresses with its incredibly natural, airy and powerful sound and with a clear housing design that has already been distinguished with the renowned “Red Dot Award: Product Design 2014"". Feature 1: "A sound to rave about With its powerful and lively response, the A 2 brings out the best performances from all dynamic headphones and supplies an excellent reproduction quality that is as close as possible to the original sound: From highs with a brilliant resolution and absolutely authentic mid-range to a deep, natural bass. Two stereo cinch inputs are available for connecting sources, which you can toggle using the input selection buttons on the front or using the supplied remote control." Feature 2: "Fully discrete Selected, hand-assembled components and the discrete circuit design open up a richness of detail that is hard to beat.   The cover made from special ceramic-printed glass with transparent sound-wave logo allows you to see into the inner workings that are illuminated in a warm orange hue.  Thanks to the two headphone outputs, two people can listen to their favourite music at the same time.  The A 2 impresses with its well thought out and intuitive operating concept. "   Feature 3: "Flexible As a special highlight, the A 2 provides separate adjustments for the impedance and sensitivity of the connected headphones as well as the different levels of the audio sources.  This means that headphones of between 16 ohms and 600 ohms can be operated perfectly on the A 2 without distortion occurring at high levels. The A 2’s functions can be operated directly on the device itself or using the supplied infrared remote control.  "   Other: "Made in Germany The quality promise “Made in Germany” not only applies to product development but also manufacturing: The designs created by the beyerdynamic engineers and designers in Heilbronn are subsequently crafted largely by hand by highly qualified employees in Germany. The high level of manual completion enables special quality standards."
