Kenwood X1200M Amplifier Review
For car subwoofer applications, Class D amps are beautifully efficient and their small size offers installation flexibility. Before amplifying an incoming signal, a Class D amp converts the signal to digital. Digital signals can be amplified very efficiently, so you get a lot more power with less current. Less input current reduces power supply size and generates less waste heat, thus reducing the heat sink size. The amp then converts the amplified signal back to analog.
Duak Sigma Drive
This advanced negative feed back circuit improves damping factor and increases accuracy and sound quality. When a signal is passed to a subwoofer, like a 50Hz note, the speaker will move and create the note. However, because the speaker has mass and a suspension, it won’t stop moving once it’s in motion. This extra movement (sound) creates a type of distortion that’s not part of the original signal. The negative feedback circuit senses this unwanted movement and send out an opposite pulse to stop the speaker like an electronic brake.
