GAOHOU Stereo Digital Power Amplifier Board 50W Dual Channel 360 Degree Stepless Tuning BT5.0

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. *Characteristics: Adopts domestic class D amplifier chip scheme, has high efficiency, good distortion and explosion-proof cracking sound, and strong driving force for transparent sound quality. *If this product is not mounted on an external audio device, the default power-on is BT mode. If an external playback device is mounted (such as inserting an AUX or U disk), the default is AUX or U disk playback mode at power up. Follow the principle of device priority after insertion during playback, such as inserting AUX during BT playback, and immediately switch to AUX playback. You can also select the audio mode switching on the APP, which is very convenient. *When playing AUX, please choose a shielded AUX cable to reduce noise. *If you try to use MP3 format for U disk playback, the sampling rate of WAV format must be within 44100HZ, but if the sample rate is too high, it may not be possible to play. *If you use the USB sound card function, connect your computer with a USB data cable without installing a driver, most computer systems will switch the USB sound card by default, and if it cannot be switched automatically, you can switch it manually. specification: Support Xinyirian APP Applicable power supply: DC 8-26 V/3 A or more Audio input: BT+AUX+USB drive+USB sound card Volume control: encoder 360 degree unlimited tuning Audio output: passive speaker + 3.5 mm audio interface Output: 50W*2 Output filter filter: No filter Protection mechanism: prevent static electricity, overcurrent, short circuit, overheating, etc. Heat dissipation method: heat sink Applicable wrapper: 4-8 Q, 10-200 W Size (with case): 56 mm*50 mm*18 mm Weight: 61g Parcel including: 1 x Stereo BT Digital Amplifier Board
