Some reviewers in youtube or another e-commerce said that tha amplifier are 2000W. But I don’t trust they said.
Video looking inside of the Amplifier unit are just not big enough for Power Transformer. This looks like a 200 Watts transformer.
The unit are using Final Power Transistor 2SC5198 in quasi mode and the maximum output are reaching 100 Watt each channel.
It mean that the total Power Output are 200 Watts.
Extra SHDC slot for you to play your song from memory card.
USB port can easily you to play your various karaoke song or others multimedia files.
2 sockets Microphone inlet to make you sing along with your partner.
TRACED SCHEMATIC DIAGRAM SUNBUCK AV-80
Here are the results of traced schematic diagram SUNBUCK AV-80 :
From the circuit above are consist of circuit blocks:
- Differential Preamplifier,
- Voltage Amplifier Stages,
- Driver Amplifier, and finally
- Final Power Amplifier.
All transistors are using cheap transistor 2N5551 and 2N5401 but using Final Power transistors 2SC5198.
The tracing schematic i made is has ready to simulate with software, say it Proteus. This is I always do practice to test the result of my electrical schematic drawing.
The result of simulaton are just like this:
