A state of the art 33W RMS design

This porTable PA Amplifier can be powered from the 240V AC mains or its inbuilt 12V sealed lead-acid (SLA) battery. It delivers up to 70 watts and pulls a number of tricks to keep battery current low while still maintaining very high performance.

The design is based around the Philips TDA1562Q power IC. This ground-breaking IC uses special techniques to deliver up to 70 watts from a 12V battery and does away with the need for a DC-DC inverter.
