Advantages of the Digital Amp
Full-Digital Processing
Our amplifiers use digital processing from signal input all the way through to output. Their amazing amplification lets you enjoy the full potential of today's most advanced audio sources such as
Low Noise, Low Distortion
Panasonic and Texas Instruments developed technology that helps eliminate the distortion that occurs in
High Efficiency, High Power
An advanced switching amp control method called dead time control combines with a serial snubber circuit to help conserve electric power at the output stage. This

Technologies that Zero in on Sound Quality
32-bit Floating Point DSP
The
applies
192-kHz/24-bit A/D Converter
This converts analogue signals to digital signals and delivers them to the
Pure Water Capacitor
A Pure Water Capacitor containing a rayon separator is used as the electrolytic capacitor for each of the seven audio channels. With its high water content this capacitor offers
excellent electrical characteristics and low impedance. The clean electric current it delivers to the speakers helps achieve a clear, transparent sound.
MOS-FET
The power amp section is equipped with newly developed,
channel, we downsized the circuitry and shortened the signal path. The result is a fast, powerful speaker drive that delivers highly linear,
