Features

• Advanced UHC-MOS Single Push-pull Circuit
The new generation UHC-MOS FET is employed for the power amplifier
output stage. The handling power guideline has been scaled up from 150
Watts to 260 Watts.
The operation stability affected by the temperature fluctuation is
improved by using the dual FET selected first stage for the voltage
amplifier stage. Furthermore, the phase property is stabilized up to the
high range by using the cascade bootstrap circuit.
• Power Supply
To make the most of the Advanced UHC-MOS Single Push–pull Circuit,
this powerful power supply consists of a LC mount twin transformer,
schottky barrier diodes, and a custom block type capacitor that is tuned
for high-quality sound.
• Phono Equalizer
Even a user who is particular about analog records is satisfied because
the Phono Equalizer circuit for the FET input supports MM/MC.

• Pre Out
A Pre Out connector is equipped that can extend the system's possibility
by using another power amplifier to drive a bi-amplifier with a speaker
that supports the bi-wiring or adding a subwoofer to upgrade the system.
• Adoption of a Large potentiometer with motorized function
This unit adopts a large potentiometer that is provided with higher-grade
integrated amplifiers as well.
• Resonance Suppression Design
Effects of vibrations on the audio quality of this unit have been
substantially minimized, by scattering resonance points by varying the
configurations of fins in the heat sink, as well as by lowering the center
of gravity of the power amplifier block.
