800W audio amplifier circuit
The audio power amplifier ideal for home user or PA work or for use as a general-purpose subwoofer or hi-fi amplifier. There are many people like to prefer MOSFET as their legendary ruggedness.
This circuit project had the Mosfet amplifier module which produced 800 Watt into 4 Ohm speaker load and so we decided to take a look it.
It was turned out to be based on the “Pro Series One” as mentioned above, although this version by Altronics has had derated and adapted to different MOSFET. It has a power output rate with 700W into 8W and 800W into 4 Ohm. For frequency response is within 1dB from 20Hz to 80kHz. Total harmonic distortion is rated at less than 0.1% up to full power and signal-to-noise ratio with respect to 800W is better than 100dB unweighted.
For circuit using MOSFET number BUZ902DP ,BUZ907DP which is popula take to build amplifer, If you see the circuit ,It seen 2 same circuits in the project which one circuit can gen power output at 400 Watt.

SIR, DO YOU HAVE AVAILABLE KIT FOR 800 WATT POWER AMP?
Hi, Pliz tell me about the third feedback added to the second amplifier from the speaker I failed to under. Am still prone to learn otherwise Am still captivated with the idea. Thanx
