IRS2092AMP-500W Amplifier Modules - how to tell the good ones from the bad ones at a glance!

[@tonskulus]

I think I got mixed one. Fan was loose, only two screws. Cooling fin has slots all around. There is small heat sink under it. And it works :D

Try this link for the latest version with speaker delay relay. Make sure you get the ones with the red connector

Thanks you

Thanks, have you tried the ones with built-in speaker delay relay. They work great and same price on AliExpress.com

Nope heatsink should like bad one. Because when amplifier is working link peroid of time, inductor gets hot so needed cooldown. Right ?

[@barneycarparts]

What power supply do you recommend for 100watts RMS? And, whats it sound like? Some of these "D:" class amps have all the high fidelity of an Ice Machine at a Motel 6.

Hi were do get the ground from? My 65 Volt-DC-Powersupply only features plus and minus? Why do I need the Groundcable?

[@terrycox6954]

These amps require a dual output power supply that has +/- 65vdc with a common ground. So 3 connections: +65vdc, ground, -65vdc with a total across the + and - of 130vdc
