Warm tips: 1. Default comes with ONE 24V/6A power adapter, if you want higher output please prepare another one by yourself. 2. Long press play/pause button can switch between 2.1 and 5.1 channel output mode. When switching to 5.1 channel output mode, any input modes can achieve 5. 1 channel output. 3. If you want real 5.1 channel output, please use 5.1 channel RCA input. If input 2.0 channel but output 5.1 channel, the stereo signal is processed and simulated to 5.1 channel. 4. Please note that digital inputs (USB/COAXIAL/OPTICAL) only support PCM stereo signals. Otherwise, there will be no audio output. Features Transfer 2.0 channel input to 5.1 channel output: with built-in multi-channel signal process chip and circuit, which applies professional algorithms and dynamic separation techniques. Even when input 2.0 channel audio signal, it can also auto allocate and simulate to 5.1 channel and provide excellent smart noise reduction, precise sound positioning and stereo surround sense. Multiple audio inputs to work with more devices: with Bluetooth 5.0 / coaxial / optical / U-disk four digital inputs and 2.0CH / 5.1CH RCA inputs, strong compatibility and works perfectly with most home audio devices. U-disk input supports lossless formats such as WAV, APE, FLAC besides MP3, high-quality music can be reproduced and enjoyed. Strong power output and multi-channel system building: adopting 3PCS classic TPA3116 chip, responsible for front (50W*2)/ surrounded (50W*2) / center(50W) / subwoofer(50W) outputs; specially add a low frequency output to connect another active subwoofer to easily build 2.0/2.1/2.2/5.1/5.2 channel system and enjoy shocking auditory effects as if you are in a movie theater. Independent control knobs and dual power inputs: besides main volume control and treble & bass knobs, also with separate front/ surround/ center/ bass volume control; and specially design two power supply inputs (main/vice) to provide stronger power input to easily drive most home speakers and subwoofers with high power. User-friendly design and advanced functions: with detailed function buttons and separate indicators, convenient to use and see the working status in real time; one button to switch 2.1 and 5.1 channel outputs, no need to plug in and out speaker cables repeatedly. Made of aluminium alloy and in compact size, very suitable for those who want to build a mini HIFI 5.1 channel system.
