Description
HiFi Mini Bluetooth 5.0 Power Sound Amplifier Stereo Audio Receiver USB
Note:
DC 9V-24V power supply, interface 5.5*2.5mm or 5.5*2.1mm (outer diameter 5.5mm, inner diameter 2.1-2.5mm, length 10-15mm). The plug can be attached to this machine. Recommended 12V 5A power supply.
The above is the specific value of the power supply. The power supply is not included. Please make sure this is acceptable to you before purchasing.
If you are using a USB hard drive or TF card to play music, this product can only play tracks randomly or select music using the left and right buttons. Please ensure this is acceptable to you before purchasing.
Features:
1. As a digital power amplifier and music player, it supports RCA/AUX/USB/BT 5.0/TF card inputs and is compatible with virtually all home audio devices such as phones, tablets, computers, TVs, set-top boxes, CD players, etc. U-disk and TF card support the lossless formats WAV, APE, and FLAC.
2. The USB interface supports input from USB flash drives, computers (no driver required), and phones (with OTG function). Bluetooth 5.0 ensures a stable and faster transmission speed, and the TF card slot makes it convenient to enjoy high-quality music outdoors, even on the go.
3. With the classic TPA3116 chip, the maximum output power can reach 50 W*2, which is sufficient for most passive desktop/bookshelf/indoor speakers (4–16 Ω). The sound is clear and clean, without audible noise, even at high power.
4. Compact design and exquisite appearance, attractive housing with LED display and power/mode switch, very suitable for home and desktop audio system use with 9–24 V DC voltage, allows use in car or motorcycle.

Strength and power:
The power amplifier uses the TPA3116 chip; the actual output power can reach 50W per channel, 100W total for two channels (24V power supply), and is equipped with a 12V 5A power supply. The output power is 30W x 2 (4 ohms) when connected to 8 ohms. The power output is approximately 15W x 2. If you require more power, you can configure the power supply yourself. The chip will burn out, and the power supply should not be too small, as power = voltage * current. If the current output is less than 50W, a power failure may occur.
Amplifier output:
The power amplifier is a fixed-resistance power amplifier. It supports 4/6/8/16 ohms.It cannot be connected to computer audio and other active audio devices. Four columns behind the power amplifier are output interfaces for 3.5 mm and other headphone plugs or Lotus plugs.
Vehicle modification:
Conventional 12V car and motorcycle batteries can be directly modified and powered. Large 24V batteries, such as those found in large trucks, are not recommended because the voltage will exceed 24V after the vehicle is started, unless reduced by other devices. Prolonged use is detrimental to the chip, even if it eventually burns out. If you intend to modify the vehicle or use battery power, the power amplifier's connector size must be limited to DC 24V 5A, either 5.5 x 2.5 mm or 5.5 x 2.1 mm.
