The HiFiBerry Amp2 is a high-quality, highly efficient Class-D power amplifier for the Raspberry Pi (newer models with 40 pin GPIO connector), that is mounted onto the Raspberry Pi to create a stereo audio system. The speakers just have to be connected directly, which makes it an ideal module for multi-room audio installations.
This does not include the external 12-24V power supply that is needed to operate the HiFiBerry Amp and the Raspberry Pi. You can purchase one here.
It powers the Raspberry Pi, there is no need to add an external 5V power supply to the Raspberry Pi. However if you want to use power-hungry USB components you need to use a powered USB hub.
You can’t connect the power to the Micro-USB port of the Raspberry Pi. The whole system including the Raspberry Pi will be powered from the external 12-18V power supply
Up to 60W output power
Capable of driving a pair of 4-8 Ohm speakers
Fully controllable from the Raspberry Pi • sample rates up to 192kHz
Digital-analog conversion included, no need for external DACs or sound cards
Digital sound transmission for optimal audio performance
Connects directly to the Raspberry Pi A+/B+/2B/3B/Zero, no additional cables needed
Only one 12-24V external power supply needed for both AMP2 and the Raspberry Pi, no need for USB power supply anymore
No soldering required, the AMP2 is directly mounted on the Raspberry Pi A+/B+/2B/3B in less than a minute
Dimensions without package 5.5 x 6.5 x 2.5 cm
Dimensions including package 9 x 7 x 3 cm
Weight 0.06 kg
Raspberry Pi compatibility: Note that the HiFiBerry Amp2 works only with the newer Raspberry Pi model A+ and B+,2, 3, not with the older model A/B.
