Its interesting to observe a Power Amplifier that below Rp.1M but it can reaching up to 2000 Watts of audio power in SUNBUCK MP326BT. Is it true?
An audio Power Amplifier name SUNBUCK with series number of MP326BT are made from China mainland and it has be sale over the world such as Indonesia, Europe, Russia and others.
In my country, the name are so famous because its a cheap enough to purchased.
FACT OR FAKE: BELOW Rp. 1M but POWER UP TO 2000W
After i saw the video, inside of the Power Amplifier are using a pair of 2S5198 in quasi mode for each channel.
It mean the Power amplifier are 100 Watt maximum output but it only say 60 to 70 Watts in 4 Ohm load.
100W are maximum Power Dissipation of its Final Power transistor and 60/70 are effective output audio power.
This is a inside of the amply and wiring of the power amplifier:
TRACED SCHEMATIC DIAGRAM OF SUNBUCK MP326BT
After a few hours to observe, this is a result of the Power Amplifier section:
Note: Schematic diagram picture above are can be wrong in number of value or wiring.I do tracing the module are with my own perspection.
Block of schematic diagram consist of:
- Differential preamplifier,
- Voltage Amplifier Stages,
- Driver Amplifier, and the last is
- Final Power Amplifier.
Power section of SUNBUCK MP326BT are using a quasi power transistor 2Sc5198 that its 100 Watts dissipation output (DATASHEETS).
