Subwoofer Amplifier TDA7379 2.1 Channel Audio Amplifier Board 13Wx2+38W Bass DC

Subwoofer Amplifier TDA7379 2.1 Channel Audio Amplifier Board 13Wx2+38W Bass DC 12 to 22V Ship to worldwide via post air mail with tracking number. Feature:Power supply requirements: single DC DC 12 ~ 20V power supply, power supply 3A ~ 5A can, the board has 5.5mmx2.1 specifications DC power connector, you can directly use the laptop power adapter (usually about 18V) or monitor with 12V power supply are Yes, the power input to increase the 2-terminal, easy to connect the user without direct wiring, [recommended voltage 14 ~ 20V DC] [Horn match]: the proposed use of 4 or 6 European speakers can be, especially the 2.1 channel, the left and right channel output power is only about 13W, with 8 ohm speaker sound relative to 4 ou to be smaller, with 4 ~ 6 European speakers will be larger speakers, it is recommended to use 3 to 5-inch speakers, in order to get better sound quality【Amplifier parameters】【Power amplifier chip】: TDA7379 【Power supply】: 12 ~ 20V DC DC 【Current】 ≥3A【Output power】: 2.1 channel 13W x2 + 38W bass【Product Size】: Length 83mm X Width 79mm X Height 25mm (size does not contain potentiometer handle handle protruding part) The first use of graphics card radiator structure of the amplifier board, compared to the traditional aluminum radiator, increase the cooling fan can take the initiative to reduce the power amplifier chip and radiator temperature, similar to TDA2030 TDA2005 2009 TDA7297 and other power amplifier board, most manufacturers to control costs, , The small size of the aluminum radiator, the actual use of the process, the heat generated by the amplifier chip is still quite large, hand touch is hot, some serious may also burn your fingers. Heat accumulation in the aluminum radiator, the accumulation of more, high temperature will affect the performance of the amplifier chip, like the graphics card, the high temperature when the computer is not feeling the operation is not smooth, picture card, picture overlay, screen defects and other performance problems , The amplifier chip is the same, high temperature will have a certain impact on the sound quality, serious will be intermittent playback or sound quality significantly worse. The use of graphics fan fan-type radiator, greatly reducing the power amplifier chip temperature, touch the warmth of the warmth effect only, effectively avoid the use of high-power heat dissipation on the power amplifier effect SHIPPING1.
