Hardware volume control for DAC. You can control the output volume 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
HiFiBerry DAC+ ADC combines the well-know DAC+ with an analogue input. Both input and output support sample rates up to 192kHz. The HiFiBerry DAC+ ADC 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, optimized for one specific use case: the best audio playback quality. It is specifically designed for applications that do not only need playback, but also recording functionalities.
Item Specifics Weight: 30 g Dimensions: 5.5 × 6.5 × 2.5 cm Compatible with Raspberry Pi A+/B+/2B/3B/3B+/4B+/ZERO Note that you might need to update your Linux kernel to support the audio input features (at least Raspberry Pi kernel 4.18)
