Our HiFiBerry DAC+ Pro comes with integrated dual-domain ultra-low-jitter clocks and gold-plated RCA connectors. It can be simply plugged onto your Raspberry Pi, without any soldering.
This is our HiFiBerry DAC+ Pro with a pair of XLR jacks.
I 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.
