Overview
This HiFi AMP Pro Hat is a high-quality, highly efficient, up to 2x80W peak Class-D power amplifier output for the Raspberry Pi. Just plug it into Raspberry and do some simple configuration, you can get a same high-class music player, but only pay 1/10 to 1/100 of the market price. This is a good choice to DIY your home stereo theatre or broadcasting system.
On-board MA12070P is a super-efficient audio power amplifier based on proprietary multi-level switching technology. Features an embedded digital power management scheme. The power management algorithm dynamically adjusts switching frequency and modulation to optimize power loss and EMI across the output power range. It supports sample rates from 44.1 kHz to 192 kHz, 2x30W continuous output and 2x80W peak output.It is largely used in Soundbars, Multiroom Systems and Home Theater Systems.
Features
For Use with
Compatible with all current models of the Raspberry Pi using a 40-pin header, such as Raspberry Pi 4 / 3B+ / 3B / 2B / B+,etc.
Operating System
Support Raspberry Pi music player system, such as LibreELEC OSMC, Raspbian, RuneAudio, Volumio, Moode, Ubuntu etc.
Support play music from a hard disk or over the network.
How to Power
Power via AMP Pro: 9-24Vdc +/-5% , ≥3A
Note:
- Only connect one external 12-24V power supply to AMP Pro, and don't connect extra power supply to Raspberry Pi Motherboard.
- Refer to the datasheet from Infineon. Don't hot swapping the AMP Pro board, otherwise the board will be burned! The right approach: Connect the power adapter to AMP PRO board, and then power up the adapter.
