300W Audio Power Amplifier circuit

I will share my experience with the BUZ902DP  with other fans to share my passion for this minimalist perfection.I amplifier for the durable, easy to use, while the high fidelity to the original sound source and advise the partnership, this amplifier with other products of excellent quality.
When I began the design of this amp, my goal was to make a product better suited for the reproduction of complex music and voice. Although I emphasize the high electrical properties, the most important requirement is to create a superior sound, vivid images and superb spatial aural clarity.
Although the average level of listening is usually less than 10 watts, my design concept was to an amplifier with plenty of reserves, but the deviation is for Class A, at the height of the audience of cross-over distortion at a very low level.
There is no place in the pathway, enhances the precision of the tonal characteristics of instruments and voices clearly.
The BUZ902DP is virtually zero phase distortion over the audio range resolution is perfect and completely color the sound.

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.
