Hifi amplifiers board in comparison

Bluetooth Amplifier Board 100W and 100W amplifier board with treble and bass control, DC 12 24V, BT and AUX inputs, 2.0 channel stereo amp board for DIY wireless speakers, without password.

High Power Circuit design using A970 C2240, high voltage sound pair of dual differential circuit and A1145 C2705 for voltage amplification to promote the use of medium power pair of tubes A1837 C4793, the output stage using A1943 C5200 high power for Toshiba pair of tubes.

High Performance The TPA3116D2 is a Class D amplifier IC from TI that has very high index parameters. Advanced oscillator PLL circuit uses multiple switching frequency options to reject AM interference. The modulation frequency can be up to 1.2MHZ, and the high power output distortion is less than 0.1%. This helps prevent noise. With a filter inductor, the sound is round and clear.

With Standard Lotus Socket External Sound Input,it Can Be Connected to Computer,mobile Phone and Other Audio.

Power Supply The power supply is recommended to be a power supply with a good filter of 70V DC dual power supply. Speakers are recommended to use 10 18 inches 4 ohms 8 ohm speakers.

2. The PCB circuit board size is reduced, the component layout is more reasonable, and the product service life is increased.
