The wide-range DC Integrated Amplifier aiming at
pulling out the charm of compact disk fully.
The model which
strengthened vibration proof and thermal resistance with the high-density fill
is adopted as the transformer of a power-source part.
electrolytic capacitor for audios with a quick charge-and-discharge speed is
The rotary switch and volume which are driven by the small motor of a microcomputer
control are adopted, and the remote control of an input function switching
and volume control is realized, without affecting a tone quality.
In order to suppress the slight oscillation which a power transformer
causes, the strap mounting structure of attaching a transformer to reverse is
adopted, and the oscillation is reduced using the self-weight of a transformer.
It is possible to amplify without carrying the Source Direct and going
via an accessories circuitry with little frequency in use, such as a balance
volume and a Subsonic Filter.
In addition to the loudness which raises a high region and low-pass, bass
Booth who reinforces low-pass with a small bookshelf speaker is added.
A control in a total of four modes of every a two-step is possible respectively.
gilding compact-disk input terminal is carried.
The MC/man month phone
equalizer is carried.
The polar attached-indicator power cord is
