FEATURES

Newly developed technologies assure excellent
performance and tone quality

Pure sound

A head chassis, named Gibraltar" which provides high
rigidity and periodic damping characteristics, is employed to
reduce distortion caused by vibrations.

This reduces air vibrations caused by floor and speakers and
also reduces vibrations caused by the power transformer
and power transistors.

Spontaneous twin drive power circuit

Condensers having large capacity are used for the voltage
amplification drive stage of class A and power output stage
of class B. Thus, a stable output and high quality sound are
obtained. resulting in exclusion oi power interferences.

The class A stage realizes a stable operation free from
interference of the power stage even when an instantaneous
or strong output is received.

Simple and direct tone control

The tone controls consist of only passive elements to
minimize the deterioration of tone quality at the tone control
circuit.

Tone control elements can be passed by depressing the tone
switch.

Source direct switch

A source direct switch is employed to reproduce high fidelity
sound.

Any source can be reproduced without passing through the
circuits of tone control. subsonic lilter, mode switch and
balance control.

Super legato linear system

The power amplifier drives low impedance speakers and
assures powerful reproduction without low crossover
distortion and switching distortion over the wide range.
