IRCore2000 1000W IRS2092 Class-D Amplifier Blank PCB
Mono Class-D amplifier based on IRAUDAMP9.
The design implements a heavy duty gate driver circuit (FZT853 + FZT953) for operating 2 pairs of IRFB4227 mosfets.
The circuit has no onboard input buffer, so you can use your favorite preamp to get your sound preference.
The output sound is warm, thick, and has good instrument separation, it can be used as your main full range stereo amp and will beat most IRS2092 implementations which are commonly bright sounding and analytical.
The module is capable of delivering clean 600W into 4 ohms and 1000W burst into 2 ohms load.
Quality solder joints are very important to achieve optimum performance, so the builder should be highly skilled in soldering and should have an experience in building DIY amplifiers.
