Characteristics:
* Audio input: 3.5mm stereo input, RCA stereo input, TF, U disk, USB audio input (can be a computer / mobile phone / OTG / tablet OTG).
* MPT / WAV / APE / FLAC) has U disk and TF card playback.
* MP3: sampling rate / 8-48K, bit rate / 8-448Kbps, bit width / 16-bit channel / mono stereo.
* WAV: sampling rate / 8-48 KB, format / WAV ima / Microsoft AD PCM / WAV PCM, bit width / 16 bit.
* FLAC: sampling rate / 8-48K, bit width / 16 bit.
* APE: FAST / NORMAL coding, bit width / 16 bit.
* The amplifier can be include a mobile phone, computer, tablets, notebooks, MP3s, access and projectors with AV audio (lotus socket) or 3.5mm headphone output holes. A separation from common
* The power amplifier uses the TPA3116 chip. Actual output power can reach 50W per channel, 2 channels total 100W (24V power supply), equipped with 12V5A power supply. The output power is 30 W * 2 (4 ohms) when connected to 8 ohms. The power is approx. 15W * 2. If you need more power, you can configure the power supply yourself. Make sure not to exceed 24 V. Otherwise the chip will be burned out and the power supply should not be too small, since power = voltage * current if the current output is less than 50W. There may be a power failure.
* Amplifier output: The power amplifier is a fixed resistance power amplifier. There passive 4/6/8/16 ohm audio / horn. It cannot be heard with computer audio and. It is not for passive subwoofer settings. The 4 columns behind the power amplifier are exhaustion points. 3.5 mm and other headphone or lotus plugs
* Vehicle modification: Conventional 12 V batteries for cars and motorcycles can be modified and supplied directly. Large 24V batteries such as large trucks are not recommended as the voltage will exceed 24V after the vehicle is started. Unless the voltage is reduced by other devices, the power amplifier is too hot. Long-term use is not good for the chip, even if it is burned out. If you want to make changes to the car or use battery power, etc., the power amplifier connector size must be 5.5 * 2.5mm or 5.5 * 2.1mm
