The preamplifier which functions as a digital AV control center which does not
perform any signal magnification as a preamplifier, but unifies all program
sauce other than Phono.
Focusing on the function of quality AV selector,
A/D, a D/A conversion part, etc. for the DSP circuit for a digital graphic
equalizer (DEQ), mutual dubbing, etc. have taken the composition devoted to
control of sauce.
After each signal of an audio system is chosen with a
selector, as for a digital signal, an analog signal is fundamentally sent to
power amplifier straight through DEQ at power amplifier in the digital state, and volume adjustment and magnification are performed in a power amplifier
DEQ is 3 band composition whose independent setup of center
frequency, a Q-value, and a level was enabled, hardly causes sound quality
degradation for digital signal processing, but can control a frequency response.
In order to eliminate thoroughly the mutual intervention between each
signal of digital one, an analog, and video, the whole of each block has adopted
independent shield structure, and it has adopted 2 transformer systems to which
the power source has also arranged the independent transformer respectively in
the analog stage and the digital & video stage.
construction top also puts high rigidity and a unresonated design into practice.
The "intelligent communicator" which enables all the operations of
DA-P9500 and DA-A9500 by a listening position is attached.
Unlike the usual
remote control, this has realized the outstanding feeling of operation by
bidirectional communication of a system.
Operation of CD of A&D, DAT and TV of Mitsubishi, VTR, etc. and the
zoom function in which it is possible, the frequency response specified
by each contents of operation and DEQ is displayed on a liquid-crystal-display
panel, and a frequency response can be expanded partially are carried.
