For my final bachelor's (EE) project , I've decided to build a battery powered PA speaker.
I am using a single RCF CX12N251 coaxial speaker as a driver and two HYPEX UCD400HG HxR amp modules to drive the woofer and the tweeter. For DSP I am using ADAU1701 board from wondom.
The main question for me is which route should I go in regards to power supply? Because the amp modules require +/-60Vdc (Bi-Polar).
For example, using two LiFePO4 12v batteries, and building two boost converters to boost them each to 60V, put them in series and use the middle point as GND? Ofc, trying to keep the noise as minimal as possible.
Anyways, if you have any experience or similar let me know. Looking for the "best" option for a class D.
Much appreciated!!
