ITEM NAME:50WX2 audio digital amplifier board 24V 100W super TDA7492 7498 TPA3116D2 3 F8V9 50WX2 audio digital amplifier board 24V 100W super TDA7492 7498 TPA3116D2 3 F8V9 Amplifier gain using 36dB benefits: because some audio equipment audio signal is too weak, with 36dB amplifier amplification will be great, with the market 20dB amplifier amplification will be very small. Such as mobile phone output audio signal than the computer audio signal weak, with 36dB amplifier to enlarge the sound is great. If the computer audio signal, with 36dD amplifier to enlarge the sound too loud, the sound and distortion ugly, should be to reduce the computer's volume, if the computer is not easy to adjust, you can input the series power amplifier to reduce the volume (power amplifier input resistance is 1K, Use the resistor divider to change the volume of the amplifier, so that the amplifier does not appear amplified saturation distortion), is to amplify the sound without distortion, not listening. Material: metal Color: red Size: 25*20*2.2mm Package Includes: 1 x audio digital amplifier board Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
