Performance Parameters:
Working method: Class D
Quiescent current: 50mA
Work efficiency: 90%
Rated output power: 50w+50W
Source frequency response: 20HZ-20KHZ
Supply voltage: DC single power supply, voltage DC10V-DC26V
Recommended power supply voltage: DC12-24V
Maximum output current: 5A
PCB size is about: 72*59*25mm
Features:
1. Coupling capacitor adopts Italian AV, LC filter adopts Panasonic CBB and AV, which makes the sound quality more sweet and resistant.
The main filter electrolytic capacitor adopts Japanese black diamond large capacity 1800UF/25V, ensuring strong and continuous movement.
2. Using the new original ST digital power amplifier chip TDA7492, SMT high-speed placement machine patch, over-temperature reflow
soldering, the performance is very stable, ensuring a good signal-to-noise ratio of the whole machine.
3. It comes with super strong output short circuit and over temperature overload protection, and prevents the switch machine from impacting.
4. With mute port, you can connect mcu to control the working state of the amplifier
5. The line is reasonable and beautiful, the signal-to-noise ratio is high, and there is no sound from the start.
Process materials:
High-grade pure black gold plate, imported KEMET acoustic capacitor, large-capacity filter capacitor per channel. Specially made pure black
copper terminal, gold-plated audio input terminal.
Note:
When the horn impedance is 4 ohms, the working voltage must be less than 18V, the horn impedance is 6 ohms, the working voltage can't
exceed 24V, the horn impedance is 8 ohms, the working voltage can't exceed 26V, and the power polarity should not be reversed.
