The Integrated Amplifier which was developed by the
basis of the thought corresponding to digital one with PM-64, and realized AVSS
loading and a low impedance correspondence.
AVSS (auto voltage shift
supply) which shifts output supply voltage according to power is carried, and
high power-ization is realized by driving a power element with the output supply
voltage which was most suitable for each power from the Koide power to the
maximum output, maintaining a quality.
The design corresponding to a low
impedance is carried out, and power is maintained even if it changes a speaker
impedance to a very low value momentarily.
In quest of a high SN ratio
and high speed signal transmission, the direct switchpoint is carried from that
of the digital source.
In addition to man-month input, MC input is also
carried in playback of an analog disk.
