The amplifier board used in all high-grade original chip components, solid materials, including TPA3116D2 chip, never use disassemble product. . . With carefully selected components, quality gray often good. Component placement tidy appearance gray often beautiful. Overall appearance can be seen from the board, with blue Philips audio correction capacitors capacitance fever; the volume is adjusted by Taiwanese small, high quality sealed potentiometers; power supply filter capacitor using two 4700UF large pond electrolysis, high temperature low resistance and long life; Audio audio output using special red gray ring efficient inductors, high-frequency extension, high efficiency, no heat; never did adopt quality assurance cottage components. PCB board using 1.6mm double-sided fiberglass board, Kingboard A grade RF-4 plates, always highlight the high quality.

Product Highlights

1. Power delay output protection, no impact on the sound, protecting expensive speaker

2. The output power, distortion, sound reduction is high. No noise, interference current sound

3. Support DC 24V single power supply, or 18V AC power supply, dual power supply mode

4. A variety of audio input, onboard Bluetooth receiver module, or from 3P audio input jack, to meet the different modules

5. Support bass cutoff frequency adjustment (cutoff range of 180Hz-250Hz)

6. The anti-anti-circuit design, avoid the use of improper or damaged power supply polarity inversion amplifier board

7. High quality Tyrant gold slotted radiator, high-end, the atmosphere, the grade

8. Using imported chips, high-quality components, SMT chip technology, reliable quality, cost-effective

9. Product rational layout, color beautiful, like a beautiful work of art
