FEATURES

Audio current drive amplilier

An unusual current transfer circuit design keeps the preamplifier
and power amplifier stages electrically separate, thus equalling the
quality of separate amplifiers.

Legato linear power amplifier stage

The operation of the power amplifier stage is stable without any
observable distortion up through the higher frequencres, We call
this power amplilier legato linear", because its switching distor
tion is very low and its output waveform smooth.

Wide dynamic range of 120 dB

The use of Audio Current Transfer technique and legato linear
power amplifier stage has made the amplifier's dynamic range as
wide as 120 dB in actual use. This assures high-quality reproduction
of digital audio sources.

CD DIRECT switch for pure CD sound reproduction

When you press the CD DIRECT switch, all circuits whichare not
necessary for CD playback are bypassed and you can enjoy pure
digital sound.

Accepts either of the two types at cartridge
The high-gain equalizer amplifier stage using low-noise transistors
accepts both movtng-coil and moving~magnet cartridges.
