NE5532 12W+12W Audio Power Amplifier Board With Heatsink

12Wx2 Ultra-Low Distortion 8 Ohm Current Amplification Output

Description:

This module uses 24pcs NE5532 single op amps to output in parallel, maintaining the excellent performance of 24pcs single op amps in small signal ultra-low distortion. The high-level design ensures that the whole machine has extraordinary characteristics, ±15V～±18V DC power supply, power 12W+12W, ultra-low distortion output, Suitable for pushing the middle and high grade large caliber high sensitivity speaker, Not suitable to push small caliber ordinary low-grade low efficiency speakers.

This module uses exquisite materials, high-frequency double-sided glass fiber board, Board size 117x70mm, with heatsink . 24pcs NE5532. Gold-plated 8-pin op amp seat, Each operational amplifier is connected in parallel with Sweden Rifa 0.12μ 63V capacitor.

Notice:

1> This module is a current amplification output, not a voltage amplification, and must be used in conjunction with preamplifier board;

2> When this module pushes the speaker, the chip has a large heat output and must be equipped with a cooling fan.

3> Due to different assembly batches, some components on the board may have slightly different types, brands, models, and specifications. If you cannot agree, please do not purchase.

Working Principle:

Its ultra-low distortion principle is like the chorus chorus, people singing synchronously in a chorus, everyone's throat as long as easy pronunciation, keep singing in the best volume area, people's voice is overwhelming momentum, as if it is the voice of heaven! It is similar to the parallel operation of several dozen pairs of high-power transistors in power amplifiers, which can increase the output current, reduce the internal resistance, improve the damping and reduce the distortion. It is also like tens of loudspeakers of the same specification on the giant landing flagship loudspeaker in parallel, so that each loudspeaker can work in the area with the best linearity and the smallest distortion, so as to achieve a certain sound pressure level and solve the distortion of a single loudspeaker at large volume. The same is true for the parallel output of 24pcs NE5532 op amps.

Listening Experience:

The distortion is small and the fidelity is high, which seems to be a significant difference between listening to headphones and speakers. The timbre maintains the warmth and warmth of the NE5532, with a friendly and natural sound, good range balance, good transparency, wide and accurate sound field positioning, clear and distinct sound layers, deep and deep bass, natural and realistic mid frequency performance, high frequency stretching and bright, good speed, not tight or slow, and quite daring. It allows people to experience a wonderful sound of "ecstasy", like a children's chorus, as if it is a heavenly sound, clear and pure, ethereal and soft. The beautiful and holy sound gives people a feeling of an angel flying to the world, making people feel not a simple mixture of sounds, but a complete stream of melodies, almost every nerve of the listener is affected by it, making them feel relaxed and happy.
