High-frequency to low-frequency technology, accurate reproduction of the bass effect, enhance the audio shock force<br />2.Delay function design, ensure the synchronization of sound effects, to create an immersive listening experience<br />3. Optimized for car audio, strong adaptability, convenient installation, compatible with a variety of models<br />4. Built-in high-quality modules, efficiently drive the subwoofer, output strong low-frequency power<br />5. Stable circuit design, strong anti-interference ability, to ensure pure sound quality without distortion</p> <p>Principle of use:<br />Original host no RCA audio output, so the use of a high-quality high to low is necessary, the host speaker high-frequency signal input high to low, high to low conversion into low-frequency signal and then enter the amplifier. Although many people think that the host directly from the internal low-frequency audio signal to the amplifier or use the amplifier built-in high to low directly with the speaker line high-frequency signal input can not be high to low, but this type of connection is generally input into the amplifier internal signal voltage is too low 0.05-0.3V (amplifier requires RCA low-frequency signal input voltage of 0.5-7V), resulting in amplifier release to a very high volume, the speaker sound is still not enough! Loud, and lead to the RCA impedance and amplifier input impedance mismatch, easy to produce signal interference noise.<br />In addition, this high to low with control signal line input control amplifier synchronous work, to avoid the host and amplifier synchronization caused by switching on and off &ldquo;bang&rdquo; sound, and even cause damage to the speaker overload.<br />Do not remove the host to connect the audio cable, only need to host one of the 2-way high-frequency speaker line input high to low can be, generally take the original door speakers position and the host connected to the speaker line connection can be.</p> <p>Parameter:<br />Channel maximum input power 50W<br />RCA output voltage 0.2V-2V<br />RCA output bandwidth 20Hz-20KHz<br />REM maximum output control current 1A</p> <p>Note: If you do not use the BEM control function, the red, black and blue wires do not need to be connected</p> <p>Package include:<br />Audio converter *1<br />Cable *1<br /></p></div></div>
