Kit introduction:
The pure final stage power amplifier is a simple volume amplifier. There is no preamplifier circuit. The input sound source directly pushes the speaker sound without any modification and amplification. The sound is original and pure. This power amplifier board is composed of two classic voice ST company's TDA2030 power amplifier IC to form a pure final stage power amplifier, single power supply, input voltage for single-supply AC 9V-15V, reasonable component layout, powerful power (15Wx2), almost no static noise It has excellent listening, few external components and easy installation. It is very suitable for the modification or installation of home audio system. It is widely used in all kinds of active speakers. Most of the 150-200 yuan computer active speakers on the market are used. TDA2030 power amplifier IC production.

Use suggestions:
When you pick up the audio signal from the mobile phone, there is almost no noise or current. If you connect the computer, if the computer does not connect an external sound card, that is, directly output audio from the computer earphone hole, there will be some current sound. If the computer is connected to an external sound card, the sound card The audio is output, and there is almost no noise or current. The speakers that zui can drive are two 15W. The recommended speaker is 5-15W. The smaller the speaker power or the insufficient power output, the easier it is to open the loud sound. Do not adjust the volume adjustment button to Zui, and adjust to the critical undistorted position, which is the maximum volume under the existing speaker and power conditions.

Circuit description:
The power amplifier board is a power amplifier composed of an integrated circuit TDA2030. The component layout is reasonable, and there is almost no static noise, high fidelity, small distortion, few external components, simple assembly, and high power 15W+15W. Fans and audiophiles DIY, students assembled.

In the circuit, D is a rectifier diode, C11 is a filter capacitor, C12 and C13 are high frequency decoupling capacitors; RP is a volume adjustment potentiometer; IC1 and IC2 are two channel power amplifier integrated circuits; R1, R2, R3, C1 ( R7, R8, R9, C6) is the bias circuit of the input end of the power amplifier IC. Since this circuit is powered by a single power supply, the circuit can work normally when the DC voltage of the input terminal of the power amplifier IC is 1/2 power supply voltage; R4, R5, C3 (R10) , R11, C8) constitute a negative feedback loop, changing the size of R4 (R10) can change the feedback coefficient. C2 (C7) is the input coupling capacitor, C4 (C9) is the output coupling capacitor; R6, C5 (R12, C10) ensure high frequency stability when the circuit is connected with an inductive load speaker.
