This seriously powerful mono amplifier module uses the International Rectifier IRS2092S Class-D controller and four IRFB4227 Mosfets. This amplifier module is available from DigiKey ready-built and can deliver over 1000W RMS! Having described how it works and is configured last month, we will now cover assembly and testing. by Allan Linton-Smith

This mighty monoblock amplifier uses a prebuilt module and some relatively inexpensive switchmode supplies to deliver well over 1kW into 2Ω loads and substantial power into 3-8Ω loads. It can be built for around $1000 (that’s more than 1W per dollar) and fits into a metal toolbox, so it’s even portable! by Allan Linton-Smith
