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.
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.
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.
CUSTOMIZATION AND USER
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.
