The HiFiBerry DAC2 HD is a high-end digital-to-analogue converter for the Raspberry Pi (newer models with 40 pin GPIO connector). DAC2 Pro or DAC2 HD? If you’re just looking for the best audio quality – the answer is easy: the DAC2 HD. It offers lower distortions, higher signal-to-noise-range and higher dynamic range than the DAC2 Pro. If you’re on a budget, but still want a high-quality DAC, the DAC2 Pro might be your choice. DSP Add-on for the DAC2HD now available! 60W Class-D Amplifier add-on now available! Features * Stereo output * Dedicated 192kHz/24bit high-quality Burr-Brown DAC * Custom current-to-voltage output stage with high-end filtering * Four ultra-low-noise linear voltage regulators for optimal audio performance * Low-jitter clock for optimised clock performance (independent from Raspberry Pi clock sources) * Hardware volume control for DAC. You can control the output volume using “alsamixer” or any application that supports ALSA mixer controls. * Supports HiFiBerry DSP add-on module * Connects directly to the Raspberry Pi, no additional cables needed * No soldering - comes as a pre-fabricated kit. You just plug it onto the Raspberry Pi, it conforms to the Raspberry Pi hardware-attached-on-top (HAT) specification. * Compatible with all Raspberry Pi models with a 40-pin GPIO connector * Directly powered from the Raspberry Pi, no additional power supply required * HAT compliant, EEPROM for automatic configuration * Gold plated RCA output connectors * Comes with all components required to mount it. We include 4 M2.5x12mm spacers to fix the board onto the Raspberry Pi * Requires at least Linux kernel 4.19.97 Specifications Maximum Output Voltage 2.1Vrms DAC Signal-to-Noise Ratio 123dB (typical) DAC THD+N -108dB (typical, 44.1kHz, -10dBFS) Frequency Response 10Hz–40kHz (-3dB) Power Consumption <1W Sample Rates 44.1–192kHz Bits/Sample 16, 32 Resources * Datasheet Configuration Please ensure you have the most recent Raspberry Pi Linux Kernel (at least 4.19.97) by following this link: https://www.hifiberry.com/docs/archive/deploying-a-new-linux-kernel-onto-a-raspbian-based-system/ Overlay for config.txt: dtoverlay=hifiberry-dacplushd Please note: The actual board look may vary.
