Kings Among Amps

Reference Series eXcelon amplifiers carry over and include the KAC- X1R mono Class D power amp and the KAC-X4R 4-channel digital power amp. We’re also bringing back our KAC-X10D Class D amp, the KAC-X20 2-channel amp, and the KAC-X40 4-channel amp.

Series, the KAC-X1R mono digital power amp features Dual Sigma Drive, dual power supply, and is 1-Ohm capable.

Features include Dual Sigma Drive and DSP technology, and several eXcelon amps (and the KAC-9104D) are 1-ohm load capable, so when it comes to system demands, these amps deliver.

Rated at 1200 Watts RMS (2400 Watts max power), the KAC-X1R mono digital Class D amp uses Dual Sigma Drive technology that provides an excellent damping factor. Damping factor measures how well an ampli- fier controls a woofer. The higher the number, the more it limits distortion caused by unwanted woofer movement.

For subwoofer applications, Class D amps are 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 ampli- fied 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. This process allows Class D amps, like the KAC- X1R, KAC-X10D, Kenwood KAC-9104D, and KAC-8104D, to crank more power than Class A/B amps of the same size.

Kenwood’s Power Couple

More potent than Brad-jolina and Tom-Kat combined, the dual power supply on the KAC-1XR and KAC-X4R provide one power supply for positive current and one power supply for negative current. The result is a cleaner voltage source, less failure due to short circuit or power loss due to variances in transformer tolerances, and less transformer noise.

Talk about your threesome! The KAC-X1R works perfect- ly with a pair of KFC-XW1200F or KFC-XW1000F shallow- mount subs. The amplifier is small, easy to install and, in this configuration, delivers 1200 Watts RMS!

The Class D Difference

Class D amps give your customers stronger, louder, more chest-thump- ing bass with reduced current demands than Class A/B amps. Class D amps are also easier on the vehicle’s electrical system, which means they are less apt to make the lights dim during bass notes.

A dual power supply with two transformers ensures steady operation, even when the positive and negative loads are unstable!

The KAC-X4R Reference Series Amplifier is a 4-channel, full range digital amplifier.

The Full Range Digital Amp

The KAC-X4R 4-channel amp uses digital amplifier technology in a full range application along with a unique DSP. This 600 Watt RMS amplifier
