The above is the specific value of the power adapter, the power adapter is not included in the package, please make sure you do not mind before buying.
When using a USB disk or TF card to play music, this product can only play randomly or select music with the left and right keys. Please make sure you do not mind this before buying.

Features:
1. As a digital power amplifier & music player, it supports RCA/AUX/USB/BT 5.0/TF Card inputs, almost compatible with all home audio device such as phone, tablet, computer, TV, set-box, CD player etc. U-disk and TF card support WAV, APE, FLAC lossless formats .
2. USB interface supports U-disk, computers (no need for driver) and phones (with OTG function) input. Bluetooth 5.0 achieves stable and faster transmission speed, TF card makes it convenient to enjoy high-quality music even on the road or outdoor.
3. Adopting classic TPA3116 chip, max output power can reach 50W*2, enough for most home desktop/bookshelf/indoor passive speakers(4-16Ω). The sound is clear and clean without any audible noise even at high output.
4. Compact design and exquisite appearance, attractive chassis with LED display and power / mode switch, very suitable for home and desktop audio system use. DC 9-24V wide voltage makes it possible to be used in car or motorcycle.

The amplifier can be connected to mobile phones, computers, tablets, notebooks, MP3s, TVs and projectors with AV audio (Lotus socket) or 3.5mm headphone output holes. A variety of mainstream Bluetooth devices for wireless transmission.

Power and power:
The power amplifier adopts TPA3116 chip, the actual output power can reach 50W per channel, 2 channels total 100W (24V power supply), equipped with 12V5A power supply. The output power is 30W*2 (4 ohms), if connected to 8 ohms. The output is about 15W*2. If you need more power, you can configure the power supply yourself. Be careful not to exceed 24V. Otherwise, the chip will be burned out and the power supply should not be too small, because power = voltage * current, if the current power is less than 50W. There may be a power outage.

Amplifier output:
The power amplifier is a fixed-resistance power amplifier. It supports 4/6/8/16-ohm passive audio/horn. It can't be connected to computer audio and other active audio. It is not suitable for passive subwoofer. The 4 pillars behind the power amplifier are output interfaces. 3.5mm and other earphone plugs or lotus plugs

Car modification:
Conventional car and motorcycle 12V batteries can be directly modified and supplied. Large 24V batteries such as large trucks are not recommended because the voltage will exceed 24V after starting the car. Unless the voltage is reduced by other devices, the power amplifier will be too hot. Long-term use is not good for the chip, even burned out. If you want to modify to the car or use battery power, etc. must be limited to DC24V 5A, the power amplifier plug size is 5.5*2.5MM or 5.5*2.1MM

Packaged Included:
1*Digital Power Amplifier(no power supply)
