Circuit Wiring

This simple mosfet power audio amplifier circuit, with TL071C and 2 mosfet power amplifiers can deliver up to 45W on 8 ohm. This schematic is based on Siliconix application and is based on variations of voltage on the 2 resistors serial inserted on the voltage supplier of the operational amplifier driver.
The MosFet transistor must be mounted on a heatsink at least 1K/W.



Amplifier efficiency is 70%, distortions at cut frequency were at most 0.2% at 20Hz on 8ohm and 10W. With a power supply of +- 30V the mosfet audio amplifier can deliver 45W on 8 ohm and 70w on 4 ohm. Remember that this audio amplifier is not protected on shortcircuits so everytime you switch on check to see if the speaker is connected.

High Power Amplifier Mosfet 400W . These amplifiers circuit can be used for virtually any application that requires high performance, low use Noise, distortion and excellent sound quality. Examples would be subwoofer amplifier should FOH stage Amplifiers, surround a canal a very powerful sound amplifier, etc. The 400W MOSFET-amplifier has four key stages of amplification. We are looking to start any Phase appropriate detail.

As the name suggests All Q ,C and ZD the Bias and buffer phases. Its main goal is to provide a stable MOSFET Gates and offset voltage and the voltage buffer amplifier stage of the High Resource capacity. What would have without the phase response and the effect Slew rate is indeed very bad. The flip side of the coin is not the extra step Introduction of an additional dominant pole in the amplifier feedback loop.

Also to what the name suggests this stage converts the voltage developed in the VAS and provides all the amps required to drive at 8 or 4 ohms. 2-ohm loads are possible for several minutes at a time. In fact, I have tested more than 1600 1kW amplifier Watts RMS at 2 ohms. But that would not be recommended as a long-term exposure at all. If it is higher than the figures of the STI-amp. Power to the AV amplifier 800 The components of the power for this amplifier are as follows, and are favored A channel or a power module alone. 1 toroidal transformer with a rating of 1kVA. Primary windings are made to fit.

This Car Audio Amplifier to run an older 8 inch pioneer sub in a bandpass box . This delivers as expected. Subwoofer sounds perfect. I tried to run it off the stock deck using the high pass but it wouldnt turn on. I took a jumper wire and touched the remote to the positive and it fired up immediately. Dont expect any help from Boss via their phone number on the box. I waited for 20 minutes before I just decided to hang up and just pick up a new deck. It sounds great.

That this amp would not do a good job pushing a subwoofer is that it only has a "Subwoofer level control". This is not to be mistaken for a crossover/low pass filter. You need some form of crossover to keep it from sending high frequencies to the speaker.
