Focal unveils Arche, a DAC and amplifier to use without moderation with your headphones
In less than three years, Focal has established itself as a key player in the high-end headphones market. International recognition from the press as well as users is testament to that. Today, the manufacturer continues to develop ultra high-performance solutions in the headphones sector with the launch of Arche, an audiophile DAC and amplifier that is entirely designed and manufactured in France.
An all-in one solution for headphones
Arche is a unique electronic solution developed by Micromega for Focal. It combines a digital-analog converter as well as two pure class A amplification modes ( voltage, hybrid ) designed especially for headphones. Arche also offers presets for every set of Focal headphones to make sure you get the absolute best from this ultimate combination. Where Micromega brings its expertise in manufacturing high-end electronics, Focal’s acoustic knowledge shines through in the remarkable performance it delivers. Music lovers therefore get an all-in-one solution for their headphones, whilst benefiting from the performance delivered by the converter to drive their home hi-fi system.
The ultimate in high-fidelity
Upon entry of the digital signal, Arche offers a resolutely audiophile design through its uncompromising dual mono construction, from signal processing to amplification.
This way, the design reduces crosstalk to an absolute minimum. The two Premium digital-analog balanced AK 4490 converters take care of the left and right-hand channels respectively.
Each converter has a dedicated regulated power supply. Used frequently in high-end electronics, these conver- ters have an extended operating range of 768 kHz - 32 bits specially designed to ensure the pure and perfect reproduction of high-resolution audio formats: Arche thus processes PCM format signals, 384kHz, as well as DSD 256. As for power, the dual mono design continues with two amplification channels equipped with a dedicated power supply.
Each amplifier operates at pure class A, the ultimate in High-Fidelity, regardless of the impedance of the headphones used. With 2 x 1 watt, Arche powers the headphones easily, providing extremely high impedances. And in addition to the extremely low distortion, this choice means it is also outstanding in terms of transient signals.
Electronics and acoustics: A carefully considered combination from the outset
There is the option to select two amplifier types using the multifunctional rotary potentiometer located on the front panel. A pure current amplifier is available in the “Amplifier” section under the designation “Voltage”. This mode provides an output impedance of just 0.1 Ohm, which results in major listening dynamics. The second “Hybrid” integrated amplifier is similar to a power amplifier as it benefits from a higher output impedance. Here, the tonal balance slightly favors the bass, midrange and extreme treble registers.
By housing these two amplifiers within a single electronic component, every user gets amplification to suit their headphones and their favorite tonal balance. Focal has also built in solutions dedicated to each of its headphones via presets with the products’ name on. Owners of Focal headphones can therefore be sure they are enjoying a combination of electronics and acoustics that is carefully thought out and specially developed from the very outset. What about the future and potential new Focal headphones? Arche will be updated by downloading new firmware onto a USB stick and inserting it into the USB port at the back of the product to automatically upload it.
