The full digital AV
preamplifier which carries DSP (Degital Signal Processor) and
processes all processes with high precision in digital
one.
Highly precise-ization of the acoustic field setup is attained by
using for surround D.S.P (Degital Signal Processor) which processes
a signal in the digital state.
Furthermore, the Dolby prologic and personal logic are begun, the
variegated mode which dresses up with the parameter of the main and
two kinds of substitutes, and can be set up finely is carried, and
it is made to be possible [ a setup ] according to the kind of
sauce, or the conditions of a listening room.
In addition to the Dolby prologic circuit of full digital
processing, the "personal logic" mode in which the adjustment
according to the environment of software or the room is possible is
carried, and DSP presence, such as a theater and the live, can be
performed, and also fine adjustment of each stage is also
possible.
Furthermore, the cinema equalizer in consideration of the
penetration characteristic of the screen, the parametric equalizer
which rectifies the characteristic of a speaker, etc. carry out
digital processing, and a play of a richer acoustic field is
possible for it according to the space between various
conditions.
The signal inputted into AVP-5000 processes all the processes with
a digital signal until analog conversion is carried out and it
outputs it with a DA converter.
Furthermore, OPT LINK, DIR (digital interface receiver),The engine
performance of each stage is raised by adopting DSP (digital signal
processor) and the discrete digital processing system which
processes each of a DA converter by the newest LSI.
In addition, after carrying out the AD translation of the signal
inputted analogically to a digital signal, it is carrying out
digital processing.
The DA converter part which constitutes the last stage of a
discrete digital processing system constitutes each of a front /
center / surround from an exclusive DA converter, and carries the
newest digital/analog conversion technology according to the
purpose, respectively for every channel.
Moreover, in order to reproduce the analog signal of VTR etc.
precisely, the newest technology is adopted also as an
A/D-converter and the characteristic which is and meets is improved
by processing a L/R channel simultaneously and carrying out an AD
translation.
A high speed and the optical fiber module of low light transmission
distortion excellent in pulse width distortion and a Jitter value
are adopted as the optical input unit. Optical transmission
stabilized compared with the former by this was enabled, and also
it is enough taken into consideration to change of incidence light
volume.
Moreover, the signal inputted into DIR (digital interface receiver)
constitutes the clock timing of the output unit independently with
the input unit in a digital filter part, and is suppressing the
influence of the Jitter at the time of optical transmission, such
as not making the phase relation of a clock influence internal
operation etc.
In order to correspond to Hi-Vision, the 20MHz (1500 or more
horizontal resolution) high bandwidth video selector circuit is
carried in the image part.
Moreover, the image output carries the S terminal and the composite
connector. furthermore, ounce -- two kinds, a clean possible
monitor output and the monitor output only for high definition, are
carried.
Furthermore, the discrete four-channel input (input only for rear 、
center channel) terminal corresponding to Hi-Vision (3-1 system) is
carried also in the audio input part.
The copper-coating chassis and the aluminum shield have separated
the core of amplifier into five blocks, and thorough exclusion of
the mutual intervention is carried out with constituting a power
supply circuit, a digital circuit, analog circuitry, a video chain,
and display / control circuit as an independent block.
In order to perform purer signal regeneration, the transformer of
an audio system, and video / control system is made to become
independent, respectively.
Moreover, while adding a filter to AC line, respectively and
eliminating a mutual intervention, the influence from external
apparatus is also reduced.
The analog signal input unit carries the direct play function by
highly efficient relay, and is suppressing the transmission loss by
transmitting an incoming signal to an output terminal by a curtate
distance to the minimum.
Single channel buffer amplifier was adopted as the analog part
which transmits a signal to power amplifier, and also aluminum
die-casting motor drive volume is adopted as all the channels at
volume.
When using AVP-5000 as a preamplifier only for an audio, the
video-off function which shuts out a video chain from a power
source is carried.
The multi-function FL display is carried and 24 characters, a dot
matrix, and the De Dis play-off are possible.
The study remote control with liquid crystal display and a back
light is attached.
