Datasheet Aamp60

Overview

The AAmp60 is an analoge amplifier add-on to some HiFiBerry boards. It plugs on to of your HiFiBerry DAC board and adds a 60W analogue amplifier to it. It cannot be used standalone without a HiFiBerry DAC.

Facts

Up to 2x30W output power output
Uses a single external power supply 12-24V (see below) to power the amplifier, DAC board and the Raspberry Pi
No soldering, comes as a pre-fabricated kit, just plug it onto the Raspberry Pi.
Comes with all components required to mount it.

Hardware and speaker connectors

L/R outputs can’t be bridged!

Note that the actual board might look a bit different. Layout and components might change without further notice. We do not guarantee a specific PCB layout or specific components.

The Aamp60 will power the Raspberry Pi. It is powerful enough for any Pi up to the Pi4B. Note that additional hardware drawing lots of power (e.g. hard disks, displays) might require an external power supply.

Compatibility

The Aamp60 can be plugged onto the following boards:

The combination of the DAC and Aamp60 won’t fit into the standard HiFiBerry cases.
