ALE uses a proprietary software which manages the mains energy and delivers the right voltage at the exact frequency to the turntable motor.

The internal DSP analyzes the input current parameters and reworks them providing a clean and constant voltage. Through a precision quartz, it generates a perfect sine wave at the requested frequency with no electric noise. In this way the platter rotates at a very stable speed with a lot of benefits at the listening.

In addition ALE allows the electronic selection of the speed of 33.3 - 45 - 78 rounds per minute.

This integrated amplifier provides a significant step up in performance from previous versions by using everything that we learnt when developing the fantastic XR Series, but retaining the familiar design of the Classic series. The circuit design has been completely re-designed and the majority of the internal components have been upgraded by the Cyrus R&D team, which has resulted in sound improvements that will help the Classic series retain a loyal fan base for years to come.

Providing multiple supplies, all of the output voltages from the PSU-XR are all digitally controlled internally, so are extremely stable and virtually noise free. The PSU-XR really is our best performing power supply, capable of providing up to 60% more power than the PSX-R2 and due to its revolutionary design, is up to 50% more efficient.

The VOX is a unique D/A converter with a headphone amplifier and external power supply. Its entire architecture is built from the scratch using Audiobyte proprietary technologies. Every feature was developed through extensive research to provide a natural audio experience.
FPGA DAC
The VOX is built around a Xilinx 7-series FPGA device. FPGA = Field Programmable Gate Array – a piece of silicon which allows development of custom hardware. All main functions of the device are specifically made inside the Xilinx device which is updatable, meaning new software will refresh the dac on the hardware level.
The architecture of the VOX is pure 1 bit. All incoming sample rates are converted inside to a sample rate equivalent to DSD256/512 (firmware dependent), after which analog conversion is done using current segment technology.

Attaining a high performance 1-bit converter requires extensive digital processing. In order to keep a pristine sound quality, the processing must be done in a resolution higher than the music itself. Using 80 DSP cores running at 200 MHz and 68-bit processing, VOX has enough computing power to preserve the transparency required by the most demanding audiophile.

PHASE CORRECTION
SYSTEM
A unique feature of the Hydra.VOX is the seamless integration between analog and digital filters in orders to preserve accurate phase of the audio signal. It is well-known that any analog low-pass filter will add a phase distortion input-to-output altering sound quality.
To avoid this from happening, the digital filters inside FPGA are programmed to exhibit a “mirrored” phase response, thus cancelling the phase error from the analog domain. The result is a perfect phase response over the audio band.

The main input of the VOX is I2S, therefore this input is fully isolated to a prevent any possible noise leak from the audio I2S source.
The quality of the conversion clock is crucial in a high-speed 1-bit system. The VOX uses a high-quality DPLL clock generator which is integrated into a jitter reduction architecture. By design, it does not require any Asynchronous Sample Rate Conversion solutions to achieve this.
ANALOG
FILTER / BUFFER
While trivial in general applications, the analog buffer stage of the 1-bit DAC is a critical component. Not only must it eliminate the residual noise, but also it should have extreme performance in terms of low distortion and noise floor. In the VOX, the analog buffer stage is realized using low noise bipolar discrete devices.
DSD PURE PATH
Another feature of the VOX DAC is the possibility to directly convert DSD256/512 signals, bypassing all internal processing. This is possible only on USB and I2S inputs. Please note that volume control will not be available if this setting is active and headphone output will be muted.
CUSTOMIZATION AND USER
INTERFACE
The VOX is a versatile software defined DAC. This means that many features, graphical interface and even the sound signature are not fixed - they can be changed by updating the firmware.
At the moment, we are developing 3 distinct firmware versions, called Rocket, Bullet and Torpedo, each one with its own sub-versions. Even the most demanding audiophile can find the perfectly tailored sound. To access firmware section please register your device here.
The DAC can be controlled directly on the touchscreen or via control app available for iOS and Android.
HEADPHONE AMPLIFIER & PREAMP
The VOX has a 35-bit data path and a very high quality 32-bit volume control, therefore can drive directly any power amplifier. The built-in headphone amplifier is entirely a bipolar discrete design with a max power of 3W/16 ohms.
EXTERNAL POWER SUPPLY
The VOX is entirely powered from the Hydra.ZAP dedicated power supply, which provides analog power for the headphone amplifier, digital voltage and an ultra-low noise reference voltage.[/expand]
