TPA3255 Bluetooth HiFi Power Amp 2.1 Channel Amplifier Bluetooth 5.0 Amplifier Assembled Black

TPA3255 Bluetooth HiFi Power Amp 2.1 Channel Amplifier Bluetooth 5.0 Amplifier Assembled Black

Description:
To meet the needs of modern home HIFI audio-visual combination, a high-power 2.1-channel power amplifier with two TPA3255 as the core was rolled out. Built-in high-speed switching power supply and 2.1-channel core board, which can be connected to audio sources such as mobile phones, TVs, computers, Blu-ray CDs, etc., and a pair of stereo speakers and a subwoofer, the sound quality is very HIFI, the low frequency is strong, the maximum output of subwoofer is up to 600W, and the maximum output of left and right channels is 300W+300W.

It can be connected to a mobile phone via Bluetooth and supports lossless protocol for APTX-HD, which is very convenient. Bluetooth output is independently decoded PCM5102A, which can make wireless effect exceed the wired audio source. Bluetooth is also very easy to use. Turn on Bluetooth on your mobile phone and pair the device to use it. When Bluetooth is turned off, other wired audio sources can be connected.

The machine uses a large number of high-precision imported originals, such as NE5532 operational amplifier, high-current dedicated output inductors, etc.
