Field of application:
Laptops, Desktop card audio, Desktop computers, Low-voltage audio systems, Music phones, etc.
Supply voltage DC :Voltage 4.9-5V, Voltage can not be higher than 5V; current 2A-2.5A
It should be reminded that if the power supply and the horn are not well matched, and the level of the audio source cannot meet the requirements, the power will naturally not be achieved, and the on-site listening to the sound quality can be used to listen to the sound quality at the time. Secondly, we will weld the anti-reverse diode IN4007 on the power line when it is shipped. If you do not destroy the board in a short time, you will need to remove the diode after wiring because the voltage will drop 0.7V after welding 4007. Will affect the voltage value
Selection conditions require:
Power requirements: DC DC voltage 5V (4.8-5V), the current should have more than 2A; (If the power supply from the USB here is more than 2.5A power at the same time the power line must be able to cross such a large current, often current There is such a big, but the line is not the same; Second, mobile power to use the original authentic manufacturers and to ensure that the discharge capacity to meet the standard (because this type of product is the way through the lithium battery boost), the cottage not only not keep current is not constant The flow is unstable, especially its instantaneous current is not able to (can&39;t afford or distortion breaks) easy to damage the board, pay attention
Speaker Requirements:
(Satellite) Left and right channel sub-box speaker: Use 4 OHM/5W full-range speaker. (Please use 4ohm 3W for USB power supply)
(WOOFER) Woofer: Use 3-4OHM(Ω) 10W-15W Woofers. Never use 6Ohm or 8Ohm Woofers; (Please use 4 Ohm 5W when powered by USB)
Audio source: optional MP3, MP4, computer, PC, mobile phone, etc.
The woofer is mounted on the main cabinet body and the inverted phase hole is well sealed (be sure to assemble after listening to the bass), two sub-boxes are equipped with two full-range loudspeakers, three to be separated, the main cabinet is recommended to open a 50-60MM Inverted hole, box please choose wooden
The woofer must be well matched and then installed in the cabinet to make the inverting hole. Other seals are good, and the speaker impedance, mouth and height should be paid attention to. If the impedance and the oral divergence are not enough, the stroke of the note is not enough, not only the sound is also small. No bass
