The power amplifier board has stable performance, reliable quality and perfect protection function:

1. DC output protection

2. delay start

3. short circuit protection

4. overcurrent protection

5. high temperature protection

The board is suitable for high fidelity household, stage, professional power amplifier, full power, sound clarity and sound! In order to find the most clear, pure tone, the input IC processing, and then through the dual differential high frequency transistor circuit for pre amplification, the transistor that clear and delicate tone to the end, so that the tone is more than 10%! To promote the use of level two, first use the original import of medium power Toshiba to pipe 2CA1837/2SC4793 to promote a pair of TTC5200/TTA1943, then the high power to tube push 11 pairs of TTC5200/TTA1943 parallel output! This board uses a genuine original matching tube to ensure high resistance to high voltage and current to ensure a good effect and a shock force to propel the speaker!

The PCB circuit board with thickness of 1.6mmFR-4 high-grade double-sided board, metal film resistance is 1% Taiwan imported high precision error resistance, small capacitance all original capacitance coupling capacitor. The plate adopts advanced materials stress, after repeated test development and results. The circuit design is reasonable, layout and wiring pay attention to neat and beautiful, pay more attention to the sex to noise ratio, noise is zero! Pure and sweet sound quality, outstanding details. Please rest assured to buy this piece of Taobao fans: small volume can be difficult to push Hivi bass horn push dripping to do! Let you burn it up!

The power amplifier board has low distortion, low noise, high voltage resistance, switching machine silence, over temperature protection, overload protection, output short circuit protection. Circuit design is further perfect. Very high noise ratio, close to the speaker, it is difficult to hear the noise!

The supply voltage range of the board is very wide, and it can work reliably between the DC double 50V-110V (the recommended working voltage of the bare board is taken as the intermediate value, the DC double 55 volts, and the power of the power transformer, of course, the bigger the better). This is especially important in appreciating great dynamic music. It will let you really understand what is the earth trembled and the mountains swayed a sense of shock.

Use voltage: DC positive and negative 50-110V, protection circuit needs separate power supply (DC 15-25V, or AC 12-18V), in order to pursue large dynamic and power, recommend the use of DC positive and negative 90V (AC double 70). The power supply should be above 1000W.

Technical parameter:

Output power 8 ohms: 1500W, 4 ohms: 2500W frequency response: +0dB/-0.8dB (20Hz~26KHz)

Total harmonic distortion: less than 0.3% 8 ohms 20Hz~26KHz

Signal to noise ratio: (20Hz--25KHz): A weighting, full power output >98dB


Power amplifier board 300mm long X, wide 84mm, high 92mm
