New HiFiBerry Sound Cards: DAC+ Pro XLR Now Available!

Today, we are happy to announce another HiFiBerry sound card that joins our repertoire of Max2Play. The HiFiBerry DAC+ Pro XLR can finally let you add XLR HiFi equipment to any Max2Play system and create a multiroom environment with studio quality end devices.
The DAC offers the simple Max2Play integration like all Max2Play sound cards. Just select it in our web interface, reboot and the card is set up. Below you can find out why and how exactly the new XLR DAC can improve your audio system, in addition to a few other new cards by HiFiBerry for special applications that we introduce as well.


The HiFiBerry DAC+ Pro XLR is a DAC+ Pro with symmetrical, gold-plated XLR outputs. These outputs offer some noise-reducing advantages over the standard RCA’s:

The sound card delivers an improved jitter resistance, especially when using longer cables. At a distance of 1-2 meters from the amplifier, the RCA’s of a normal are fully sufficient. However, if you reach a distance of 10-20 meters between DAC and amplifier, the XLR can reduce interference more efficiently.

The XLR version is designed for customers that want to use the DAC+ Pro within professional studio environments that utilize symmetrical inputs.

Important: It is recommended to only use the DAC+ Pro XLR in its case to protect its connectors.

Other new sound cards from HiFiBerry

Aside from the DAC+ Pro XLR and the new, improved AMP2, HiFiBerry also recently released some interesting other sound cards for special application fields. We at Max2Play were able to test these new boards and want to share our thoughts here. Unfortunately, these special features are not directly applicable in Max2Play. However, with our Plugin Builder you can create applications and use cases for them yourselves.


Der HiFiBerry DAC+ RTC is a special Digital-Analog-Converter for the Raspberry Pi. This sound card is adevice designed for a specific application: The RTC-Version comes with an integrated realtime clock. This ensures that your system is always on the right time, even when the Pi is shut down and cannot connect to a time server after the next boot (e.g. by losing an internet connection).
