A Step Up from AMP4!

Adds dual-domain clocks derived from our DAC2 Pro

The HiFiBerry AMP4 continues the legacy of our prior designs, but adds the 2nd header to incorporate our ‘daughter board’ add-on modules like the DSP processor.  This model adds a dual-domain clock, effectively making this a DAC2 Pro with an embedded a high-quality, highly efficient Class-D power amplifier


The control of the clock circuit required major changes in the kernel driver. Therefore, you need to use the latest Linux kernel. This is included in the latest Raspberry Pi OS, but also in our HiFiBerryOS64 release. If you’re using another distribution, the best way to check is to check your /boot/overlays directory and look for a file “hifiberry-amp4pro.dtbo”. If this is missing, you’re probably using an older kernel that won’t work with the Amp4 Pro.
