HiFiBerry Studio ADC XLR

The HiFiBerry Studio ADC for Raspberry Pi is a dual-channel ADC with balanced XLR/6.5mm phone jack combo input. It can be simply plugged onto your Raspberry Pi, without any soldering. This is our Studio ADC with a pair of XLR jacks/phone combo jacks. The inputs are fully balanced, and it is specifically designed for applications that only require input functionalities for balanced audio sources. Does this make sense? Absolutely—depending on your needs. Think of a device that records audio in the field and transmits it to a central server, or one that simply records and analyses audio. We’ve seen this work well for applications like bat monitoring, where no audio output is required. It is strongly recommended to mount this board into a solid metal case. Otherwise, mechanical stress while plugging/unplugging XLR connectors might damage the XLR connectors. Note that there is no phantom power available on the inputs Features

* Stereo input

* Dedicated 192kHz/24bit high-quality Burr-Brown ADC

* Hardware gain control. You can control the input and 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

* Ultra-low-noise linear voltage regulators for optimal audio performance

* HAT compliant, EEPROM for automatic configuration

* XLR, 1/4″ combo input jacks

* Comes with all components required to mount it. We include 4 M2.5x12mm spacers to fix the board onto the Raspberry Pi
