The DAC PRO is a HAT compliant add on accessory for the Raspberry Pi.The DAC PRO users the Texas Instruments PCM5242 to deliver outstanding Signal to Noise Ration and supports Balanced Differential out in parallel to Phono RCA line le vel output. It also includes a dedicated headphone amplifier.The DAC PRO can be connected to the Raspberry Pi A /B /RPi2/RPi3 or PRi4’s 40way pin header without any additional soldering. The DAC PRO is powered by the Raspberry Pi.Component selection an d track layout have been in the forefront of our design to ensure noise immunity and best possible audio playback with the DAC PRO.The DAC PRO exposes two 3 pin headers P7/P9) used by the optional XLR board to provideDifferential Balanced output exposed by XLR sockets above the Raspberry Pi’s USB/Ethernet ports.P1 Analogue out (0.. carries GPIO27, MUTE signal (headphone detect), Left and Right Audio and Left and Right Ground.P6 Headphone socket signals ( LEFT, 2:GROUND, 3: RIGHT, 4:GROUND, 5:DETECT)P7/9 Differential (0.. output (P7: P9: RIGHT)P10 Alternative 5v input, powering the Raspberry Pi in parallel What’s in the box?1 x IQaudio Dac ProUpdate Notes:The boards changed colour to the new green board from 25/10/2024
