Electronics Help Care Amplifier circuit diagram This is an amplifier circuit diagram using STK412-150. This circuit produces 150+150 watts of output. It’s a stereo audio amplifier circuit diagram. This circuit needs dual voltage high and low voltgae. Positive high and low voltage. Negative high and low voltage.
All capacitors should be a minimum of 100 volts. The output watts depend on the voltage used. 70-35-0-35-70 voltage is used in this circuit.
This is an amplifier circuit diagram with 200 Watts RMS audio output. This circuit produces 200 watts of output. It’s a mono audio circuit diagram. For a stereo amplifier, we have to use a dual board. Here, we use 4 transistors. One pair of transistors can produce 150 watts of maximum output. In this circuit diagram, we can get 100 watts of output using one pair of transistors. Here, use 2 pairs of transistors. 4 transistors are used in this circuit.
This is a speaker crossover. It’s a 3-way speaker crossover. Every soundbox needs this type of circuit for good sound. This type of circuit reduces the noise and protects the speaker. It controls the bass and the midrange. The bass speaker will produce nice bass. The midrange speaker produces vocals, and the tweeter produces high frequencies.
Every soundbox needs this type of crossover circuit. It’s a simple crossover circuit diagram board.
