I just dug out my International Rectifier 'reference design' amplifier. It is an AUDAMP7S and is in FULL BRIDGE mode.....(good for sub amp, no?) 500x1 @8ohms. 125x2 @8ohms would seem to be fine for a number of reasonable speakers....and in a non-critical system. The amp is compact and of reasonable efficiency.... Power supply is listed at +-50v nominal.....with a min/max of 45->60...... On board there are 3 power input terminals....+, - and GRND..... Now? the question......When the board says 50v....is that peak or whatever? And If I bought a Switcher from the likes of Meanwell......Do they make a compatible PS? If I went DIY? I'd have to start with a toroid and than calculate for bridge voltage drop, change to whatever voltage the amp needs.....Again. that pesky RMS or whatever question.. Too much is never enough |

The data sheet says +/-50V. So that would be 100V between + and -. |
