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. Dual 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. Dual Power Supply This design provides one power supply for positive current and one power supply fro negative current. The result is cleaner voltage source, less failure due to short circuit or power loss due to variances in transformer tolerances, and less transformer noise even when the positive and negative loads are unstable! Infrasonic Filter The infrasonic filter eliminates inaudible ultra low frequencies that can cause unwanted distortion. The filter can be adjusted between 15Hz to 40Hz depending on the subwoofer and enclosure being used. Variable Low Pass Filter The built-in variable LPF allows the user to select a variable frequency and remove damaging high frequencies from the subwoofer pathway for more bass output with less distortion. Bass Boost Wired Remote Ready This optional KCA-WR10 wired remote allows bass boost frequency adjustments and level adjustments for bass. For example you could add a 8dB boost at 43Hz by simply adjusting the position of the knobs. If you are using two amps, you can use a phone splitter so one bass boost can operate both amps. More...
