TDA7297 Dual Double Two Channel Version B 2X15W Amplificatore Stereo Digital Audio Amplifier Module Board Ampli Electro 9V 15V

  Description:   A Version:   TDA7297 amplifier board with terminals 2.0 dual-channel 15W + 15W, which can be accessed 4-8 Euro 10-50W speakers, large volume of small stature, wide range of applications.   Voltage: DC 9-15V, Recommended DC voltage 12V, current above 2A Power: 15W + 15W Output Impedance: 4-8 Europe   The board Advantages: boot no current impact sound, hi no static noise! Sound quality is super good - treble delicate, soft, transparent, no harsh; bass strong, full, strong, and acting freely. Recently, some customers have reported that this small plate a little noise, mostly because of the power problem is not solved. After testing, the battery or power supply using 12V2A 12V30W more than a little noise transformers are not, if the switching power supply or other variable power supply, due to the poor may produce linear low-noise     The core of the amplifier board TDA7297 imported two-channel amplifier chip, the famous European SGS-THOMSON STMicroelectronics produced. DC power supply is designed to supply power directly available 12V battery voltage range: 9-15V, recommended voltage 12V, output power up to 15W + 15W, the peak power of 30W + 30W, the sound volume is small but super shock for any occasion.         B Version:   -100% brand new and high quality -AC / DC, 2.0 / dual channel / stereo,12V/2A when using, the output power of 15W +15 W, peak up 25W +25 W -Can be accessed by two 4-8Ω 10-50W speakers -A large volume of small size -High signal to noise ratio -Upgraded version of the radiator, wider and thicker, better cooling effect -Fit for Bookshelf speakers, CRT televisions, radios, and other small amplifiers     Specification:   Working voltage: DC 9-15V Power: 15W +15 W Maximum power:30W+30W Output Impedance: 4-8Ω       Package Included:   1 x TDA7297 Amplifier Board               //
