Amari USB AD/DA Converter

The Antelope Audio Amari is a hi-end 384 kHz PCM / DSD256 AD/DA converter. Its majestic sound will suit mixing engineers, mastering gurus, and the most dedicated audiophiles. The beautifully designed desktop unit is equipped with a slick touchscreen display. Amári offers 1 pair of Analog outs (either on XLR or TRS connectors), 1 pair of analog inputs (either on Combo XLR or RCA), and 2 high power headphone (HP) outputs with dedicated volume control and adjustable output impedance.

Amári offers the signature Antelope Audio industry acclaimed clocking and best-in-class 384 kHz conversion. The unit comes with two analog output pairs on XLR and TRS. Two analog input pairs are available on the back panel, one on RCA and one on combo XLR. In addition, Amári provides digital connectivity on USB, AES/EBU, S/PDIF and TOSLINK.

Antelope Audio has always equipped their units with multiple headphone outs. Amári brings this to the next level. Its 2 headphone outputs feature individual volume control. Each output allows users to Select from 17 different values of driver's output impedance including negative values in order to enhance the listening experience.

Amári employs the industry renowned Antelope Audio clocking technologies and the manufacturer's vast experience in analog circuitry and conversion. The mastering-grade audio interface offers 384 kHz, 24-bit conversion.

The desktop interface features the Acoustically Focused Clocking (AFC) jitter management technology pioneered by Antelope Audio’s Fourth generation, 64-bit clocking allows a stable and precise sampling of any incoming audio signal. Amári is also equipped with an Atomic Clock input (fully 10MX compatible) for maximum stability. An additional Word Clock input is also available.

The control set of Amári is distributed between dedicated fast-access knobs and buttons for the most frequent controls, the impressive touchscreen display, and intuitive software control panel. The touchscreen is used for the more advanced functions and volume levels visualization.

Made of machined metal and finished in Black & Gold, Amári boasts the typical Antelope Audio design symmetry and sturdy build quality. It is beautiful without being distracting. It is premium, but not ostentatious. It looks equally as great in the studio as it does in your living room. The centerpiece is a slick full-color touchscreen that provides hands-on control and extensive metering. Next to it, the stepped rotary encoders and three function buttons allow for smooth and immediate control. Amári looks and feels just like it sounds - clean and precise.

The belief that analog and digital audio are meant to thrive together is embodied in every Antelope Audio product. Amári is no exception - its abundance of connectivity options means limitless flexibility! Two pairs of analog inputs (XLR and RCA) and outputs (XLR and TRS), two headphone amplifiers, digital ports (AES/EBU, S/PDIF, TOSLINK), Word Clock & Atomic Clock inputs offer vast integration possibilities.

Amári features a pair of Stereo Headphone outs on ComboXLR connectors with a dedicated volume control knob. The output is capped at 1,4W max, with selectable output impedance from -4.6 to 85.3 Ohm available in 17 control steps. These options let you configure Amári for perfect compatibility with your favorite headphones for ultimate performance.

Amári’s high-fidelity headphone driver chip offers fully differential input (per amplifier). It is a dual-amp design, optimized to eliminate possible temperature drifts and deliver the differential signal quality each listener deserves.

In standard mode the Headphone outputs use a single D/A Converter chip with two dedicated amps (one per channel) for unparalleled performance while in balanced mode (when both Headphone outputs are in use) the Headphone outs switch and deliver one dedicated D/A Converter chip and two amplifiers (one per channel) for each of the headphone drives (left and right) therefore eliminating any noise, increasing audio performance and delivering an expansive, full tone and more refined quality to your musics presentation.

In addition to 24-bit/384 kHz PCM audio playback, Amári supports DSD64, DSD128 and DSD256 over DoP formats. Enjoy clear, present digital audio at sample rates tens of times higher than that of CDs.

Easy and intuitive to use, the Amári Control Panel gives you control over each aspect of the unit. It also places the power of a unique and flexible routing system at your fingertip

For the ADC, Antelope chose a digital low-pass filter with a short delay and sharp roll-off to achieve the lowest latency and widest bandwidth possible of 0.46 x fs, with a pass-band ripple of ±0.03 dB. Since the short delay filter only works on such a small number of samples (5) at a time, there is the shortest possible delay between the input and output stages, which greatly improves throughput.

As for the internal digital high-pass filter — the cutoff frequency is set to 1 Hz in order to eliminate DC offsets and pass the cleanest audio signal possible.

Amári offers one of the lowest pass-band ripple figures (+/-0.03 dB) in the industry. The lower this figure, the more accurate sound reproduction is and the better a filter sounds.

The ADC chips employed are two AK5778 - that are renowned both in the pro audio and in the hi-end world.

The 2-channel ADC is configured for 8-to-1 operation — that is, there are 2 A/D Converter chips per single analog input. This way, increased dynamic range and a significant 9dB improvement in signal-to-noise ratio (SNR) is achieved. And with a maximum sample rate of 384 kHz (apr: 2.6uS), Amári captures even the tiniest details in the audio signal with a resolution of 1.16nV. Designed for audiophile and studio equipment, the 8x CS43198 DAC chips used are well respected in the high-end community. They support sample rates of up to 384 kHz (PCM) and operate at the same speed and resolution as the ADC. This made it possible for Antelope's engineers to achieve bit-perfect & sample-accurate playback, with the AD-DA pass-through, rendered completely transparent. The final touch is having the power to play back DSD formats up to DSD256 (via DoP) makes for complete and versatile DA conversion

Amári offers fully differential (balanced) driver topology for the combo XLR inputs. The coaxial routing from the RCA connector (coax. input) to the driver, transports clean, pristine signal directly to the same differential driver as the combo XLRs. The key word is 'consistency!'

Likewise, Amári's analog output drivers are built upon a low noise, low distortion, rail-to-rail output amplifier that boasts a 0.00006% (-124.5 dB) THD (total harmonic distortion) and 3.3nV/√Hz noise. Antelope specifically chose a dual-amp in a single chip package in order to enhance the differential PCB layout and maximize the symmetrical driver topology.

Amári takes full advantage of the renowned Antelope Audio Acoustically Focused Clocking (AFC) jitter management technology. Fourth-generation 64-bit clocking facilitates the most precise sampling of an analog signal, at sample rates of up to 384 kHz and 24-bit depth. What's more, Amári offers an Atomic Clock input (fully 10MX compatible) and a Word Clock input, allowing you to enjoy the industry-leading clocking technology at its fullest potential.
