Assembled Black/Silver TPA3255 HiFi Power Amp 2.1 Channel Amplifier

Assembled Black/Silver TPA3255 HiFi Power Amp 2.1 Channel Amplifier 

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 B-T and supports lossless protocol for APTX-HD, which is very convenient. B-T output is independently decoded PCM5102A, which can make wireless effect exceed the wired audio source. B-T is also very easy to use. Turn on B-T on your mobile phone and pair the device to use it. When B-T 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.

Features:
- Dual-core 1200W 2.1-channel TPA3255
- Can be used with passive 2.1 speakers
