Purity Meets Performance
A revolution in active horn loudspeaker design
A milestone in the development of fully digital high-end systems. A new era in high-end audio. When listening to the ZERO 1, we immediately realize that it's an Avantgarde Acoustics horn loudspeaker.
Time for a new dimension
More integrated, compact and simple, and yet a veritable horn loudspeaker—to the very last decibel. The ZERO 1 is a dream come true—one that we have shared with many friends of our horn loudspeaker factory for over twenty years. After all, as fascinated, moved and amazed we may be by our larger acoustic transducers, we have always longed for a more compact horn loudspeaker to make the incomparable experience of Avantgarde Acoustic accessible to a wider audience of audio enthusiasts.
The ZERO 1 opens up this new road with a revolutionary size, simplified shape, hassle-free setup and fully integrated processor and amplifier technology.
Size and Design
Despite its clear, simplified shape and compact size, the ZERO 1is brim-full of self confidence as it seamlessly integrated into its owner's living environment. Moreover, its recessed spherical wave horn is a shining example of functional beauty.
Digital processors, digital-to-analogue converters, power amplifiers and loudspeakers—all in a fully integrated system. And more importantly: all of a level of high-end quality hitherto unseen in this category.
Plug & Play Installation
The loudspeakers communicate with each other via a radio link. They only need to be hooked up to the mains with the digital input of the master loudspeaker connected to the music signal (e.g. via AirPort Express*).
Absolutely no compromise. Time for digital perfection
The basics up front: A full-fledged horn system, the ZERO 1 has all of the tonal advantages provided by horn technology—the most original and natural acoustic transducer principle. Each of the two horns is driven by a 50-watt power amplifier. Without delay or distortion, sound explodes out of the mid-range and treble horns with extreme dynamism and an impressive efficiency of about 104 dB. This presentation is accompanied by the bass woofer working in tandem with a dedicated 400-watt power amplifier, delivering a spectacular rendition of Avantgarde Acoustic's “Purity Meets Performance” credo.
However, the technological quantum leap taken by the ZERO 1 comes courtesy of the perfection of the digital audio chain. The ZERO 1 succeeds in processing digital signals in uncompromising quality and transmitting them directly to the drivers without taking loss-making detours via passive filters. This is made possible by extremely sophisticated digital processing which is a trailblazer in terms of quality.
Time for uncompromising freedom
Simpler, freer and less complicated—the ZERO 1 philosophy is also reflected in its multitude of inputs. So that all you have to worry about is the music!
USB, Toslink, SPDIF and the professional AES/EBU input—this covers the entire range of commonly used digital interfaces.
However, due to the vast range of standards and frequent codex updates, as a timeless high-end loudspeaker, the ZERO 1 renounces a built-in wireless interface. Nevertheless, you can easily use the ZERO 1 as a WLAN loudspeaker via the wireless receiver of your choice (e.g. AirPort Express).
Since the ZERO 1 comes with a digital FPGA front end, analogue signals (e.g. from turntables, amplifiers or measuring microphones) must first be digitized. The input board has an empty slot for this purpose. It can be fitted with an AD board without having to open the loudspeaker cabinet.
Time for a new era
The ZERO 1 is completely different than anything else we have produced so far. And yet it sounds so amazingly familiar. “Purity Meets Performance”—when listening to the ZERO 1, we immediately realize that we have an Avantgarde Acoustics horn loudspeaker in front of us. An acoustic transducer from the high-end factory, which has been drawing on its understanding of tonal perfection for over 20 years to turn the superlative into a benchmark. An ambition that has left its mark on each and every detail of the process of creating the ZERO 1.
From the material used to craft the cabinet and horn—a highly innovative ABS polymer with outstanding tonal properties—via ground-breaking FPGA processing which redefines digital quality through a series of filtering features to top-notch amplification technology, every component radiates our passionate and uncompromising approach.
This culminates in an acoustic transducer with a convincing concept and amazing tonal presentation. A loudspeaker that is the first of its kind. Because it was created for an era that has just begun.
