Audalytic DR80 Discrete R2R DAC 768kHz DSD1024 Black
The Audalytic DR80 is a discrete resistor-ladder R-2R DAC, designed to convert digital signals to analog by means of a 26-bit balanced architecture. It supports PCM streams up to 768kHz and DSD up to DSD1024, allowing playback of high-resolution files.
Intended for a hi-fi system, it combines wired inputs and Bluetooth 5.1 reception to adapt to different sources. Its low-impedance output stage and analog volume control allow it to operate both as a DAC and directly with a power amplifier.
Audalytic DR80: Discrete 26-bit R-2R conversion
The DR80 relies on a proprietary discrete R-2R module, in which a network of precision resistors converts the digital signal into an analog signal. Its 26-bit balanced architecture relies on rigorous resistor matching, essential to the linearity of the conversion. Rather than entrusting this stage to an integrated conversion chip, Audalytic thus adopts a discrete-component design, whose precision depends directly on the quality of the network and its assembly.
Audalytic DR80: FPGA-driven digital processing
Upstream of the conversion, the programmable FPGA handles several essential functions of the DR80: clock management, digital shaping, DoP demodulation and anti-pop switching between PCM and DSD streams. This configurable logic coordinates signal processing and ensures controlled transitions between formats. The CK-01 clock module, for its part, provides a femtosecond reference to the entire DAC in order to synchronize its various circuits.
Audalytic DR80: Amanero USB interface
Jointly developed by Gustard and Amanero, the USB DDC interface relies on an ARM Cortex-M7 processor, which handles data processing with low latency. It accepts PCM streams up to 768kHz and DSD up to DSD1024, allowing the DR80 to receive high-resolution files from a computer source or a compatible digital transport.
Audalytic DR80: Power supply distributed by circuit
Segmented filtering and multi-rail regulation assign each power supply line a distinct function, in order to limit interactions between the different stages. This layout supplies the digital circuits, the conversion and the analog outputs with power suited to their respective needs, helping to preserve their operation within a complex architecture.
Audalytic DR80: Volume control
At the DAC output, a low-impedance analog stage allows the DR80 to adapt to a wide range of downstream loads while preserving the signal. The built-in analog volume control allows fine level adjustment; when the device is connected to a preamplifier or an amplifier with its own control, direct mode bypasses this function.
Audalytic DR80: Bluetooth 5.1
In addition to its digital inputs, the DR80 integrates a Bluetooth 5.1 receiver based on a Qualcomm QCC5125 chip. Compatible with the LDAC, AAC, SBC and aptX codecs, it allows music to be streamed from a smartphone or another Bluetooth source, while the wired connections remain available for high-resolution digital sources.
