HiFiBerry DAC+ ADC Pro
SKU: | 1061-1 |
Discontinued - This product has been superseded by the DAC2 ADC Pro.
HiFiBerry DAC+ ADC Pro combines HifiBerry's well-know DAC+ Pro with an analogue input. Both input and output support sample rates up to 192kHz. Note that you might need to update your Linux kernel to support the audio input features (at least Raspberry Pi kernel 4.19.60)
The HiFiBerry DAC+ ADC Pro is a high-resolution digital-to-analog and analog-to-digital converter for the Raspberry Pi (newer models with 40 pin GPIO connector). This is a special sound card for the Raspberry Pi, optimised for one specific use case: the best audio playback and recording quality. It is specifically designed for applications that do not only need playback, but also recording functionalities.
Features
- Stereo input and output
- Dedicated 192kHz/24bit high-quality Burr-Brown DAC
- Dedicated 192kHz/24bit high-quality Burr-Brown ADC
- Hardware volume control for DAC and ADC. You can control the input and output parameters using “alsamixer” or any application that supports ALSA mixer controls.
- 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 is conform 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
- Three ultra-low-noise linear voltage regulators for optimal audio performance
- Low-jitter dual-domain clock for optimised clock decoupling from the Raspberry Pi
- Mic bias voltage for the use with electret microphones
- No anti-aliasing filter in the input path for best recording bandwidth
- 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
- Audio input might require Linux kernel update (at least version 4.19.60)
Improvements compared to the DAC+ ADC base model are:
- Dual-domain clock design that provides a master clock independent from the Raspberry Pi
- Fully configurable analogue front-end that allow a wide variety of input levels (from mic level to full 2Vrms) – no more jumpers, you can do the configuration in software using alsamixer
- Microphone bias voltage allows to use electret microphones (needs to be enabled with jumpers)
- Higher input bandwidth as we removed the anti-aliasing filter in the input path
Bases on these differences, we recommend the DAC+ ADC Pro for the following scenarios:
- Everybody who likes the DAC+ Pro design
- Audio recordings that require a higher bandwidth
- Use of electret microphones
