Product introduction:
 
The power amplifier board for the welding of finished products, fool-type wiring. Directly connected to power, audio, passive speakers to work. This product uses two TPA3116D2 digital amplifier chip as the core, one to do about the channel power amplification, a bridge drive subwoofer, with small size, high efficiency, high power and so on. Materials used regardless of cost, capacitance for the WIMA, Siemens, Nikon fever capacitor. High-quality Taiwan-made high-quality sealed potentiometer, original TPA3116 chip, dedicated bass audio chip. Board circuit is simple, reliable. Operating voltage Single power supply 12V-24V. Left and right channel output 50W*2, subwoofer output 100W, the efficiency can reach more than 90%. Board small size, use and installation are very flexible and convenient. All components used in the use of genuine devices, can be long-term stable work.

Description:

It is recommended to use 19V / 4-6A power supply, then connect with subwoofer, subwoofer 5-10 inch, impedance 2-4 ohms, speaker sensitivity of about 90dB, speaker power 40W-200W; left and right channel connected to a pair of satellite , Speaker 4-6 inch, impedance 4-8 ohms, speaker sensitivity of about 90dB, speaker power 30W-60W, can be two frequency bookshelf box.
 
Need to reach the power, you can use 24V / 5-10A power supply, then subwoofer one, subwoofer 6-12 inch, impedance 2-4 ohms, speaker sensitivity of about 90dB, speaker power 60W-200W; left and right channel satellite Box a pair of speakers 4-6 inch, impedance 4-8 ohms, speaker sensitivity of about 90dB, speaker power 40W-80W, can be two frequency bookshelf box.
 
Do not need a lot of output power, you can use 12V-15V / 3A-5A above power, then subwoofer one, subwoofer 4-6 inch, impedance 2-4 ohm, speaker sensitivity of about 90dB, speaker power 30W- 100W; left and right channel connected to a pair of satellite, speakers 2.5-5 inch, impedance 4 ohms, speaker sensitivity of about 90dB, speaker power 10W-50W, can be two frequency bookshelf box.

Note:

The amplifier is connected to the speaker, not the speaker! Speaker is a speaker of the accessories, not equal to the speaker, the effect is different. If the speaker is not installed as a speaker, although the same will sound, but because the cone before and after the vibration of the sound phase is opposite, will cause the sound offset each other (commonly known as acoustic short circuit), causing the sound small! And the speaker is no box, there is no resonance cavity, can not produce bass!
 
If you make your own speakers, please follow the general speaker production tutorial operation, scientific calculation of a good box volume, guide tube size, frequency divider frequency points, subwoofer without frequency, must thick wood, paste sound-absorbing cotton, do a good job can not leak.
