DC 5V 20W 2.1 Channel Subwoofer Amplifier Board 3D Surround Digital Stereo Amplifier AMP Board T0318
Feature: 1.Mainboard sound source input adopts two channels of sound source processing, which makes it convenient, practical and multi-functional. And it comes with the dual-channel 3.5 audio port and 3P audio input. If the 3.5 headphone port connects another source when the 3P port connects the sound source, the 3P will be automatically disconnected 2.It reserves the output terminal of the power supply (when it is used with the decoder board of our company, the decoder power can collect electricity from here to realize that the regulator board can control the total power supply, that is, the power supply of the decoder board and the power amplifier board). The standard terminal is not welded 3.Suitable for laptop computers, desk speakers that insert the card, desktop computers, low-voltage audio systems, music phones, etc. 4.This module connects 5V/20W and adopts 8509 and 8575. Processed by peripheral hardware, its max power could be up to 20W. The DC voltage of the power supply is 4.9-5V, and the voltage cannot be higher than 5V. As for current, it is 2A-2.5A 5.Notice: If the power and the speaker cannot work well, and the electrical level of the sound source cannot meet the requirement, naturally, the power cannot be achieved Specification: Type:Audio Module Sound source:PC,MP3,Cellphone Theme:Houses Application:Laptop computers, desk speakers that insert the card, desktop computers, low-voltage audio systems, music phones, etc. Requirement: DC voltage:5V(4.8-5V) Current:over 2A When powered from USB, the power needs to be over 2.5A and the power cable is required to be able to pass such current. If the current is enough but the cable cannot pass the current, it still cannot work. In addition, the power bank needs to use the original authentic one and it needs to ensure that the discharge capacity should be up to standard, as this kind of power bank uses lithium electricity by boosting. The fake one cannot keep up with the current, and its current is not stable and constant. Especially, its instantaneous current cannot keep up, which may damage the board and cause a mismatch, alternative pronunciations, or distortion, etc. Speaker Requirement: Satellite left and right channel auxiliary box speaker---Uses 4ohm/5W full-frequency speaker. When powered by USB, please use the 4ohm 3W one Woofer speaker---Uses 3ohm-4ohm 10W-15W woofer speaker. The 6ohm or 8ohm woofer speaker cannot be used. When powered by USB, please use the 4ohm 5W one The woofer speaker is mounted on the main box, and 2 full-frequency box mount 2 full-frequency speakers. 3 speakers need to be separate. It is suggested to dug a 50-60mm open port on the main box. And please choose the wooden box Note: Due to the screen difference, the color might be a little different from what you expect, please allow it Packaged include: 1 x amplifier board
