Feature

●EXCELLENT SOUND QUALITY WITHOUT DISTRIBUTION: With two TPA3255 power amplifier chips, the digital amplifier board is a powerful Class D power amplifier that delivers truly first-class sound quality. Equipped with an advanced integrated feedback design
●EXCELLENT PERFORMANCE The digital amplifier board has a thickened heat sink, quiet and durable fan, which first solves the problem of heat dissipation and fully exploits the advantages of high performance. With six for Nichicon green coat HIFI electrolysis
●Excellent inductance: the subwoofer of the amplifier board uses four powerful digital AMP special inductors, has a large current, low magnetic loss, small parasitic capacity, low heat generation and uses anaerobic copper wire to improve sound quality. The magnetic shielding
●Shielding signal: the outer winding shielding of the Bluetooth amplifier board is made of environmentally friendly tinned high density copper wire, which has a good shielding effect on the connection signal. Low floor noise, no impairment due to direct
●Adjustable amplification: the multi-level Bluetooth gain of the digital amplifier board can ensure the signal strength and sufficient output power, but also fine tune the gain difference between the left and right channel. Change the R and L resistance to change the gain t
