The AV amplifier corresponding to the Dolby prologic.
The Dolby prologic
surround-sound system is raising the channel separation of order and right and
left by leaps and bounds by carrying a directivity emphasis circuit as compared
with the conventional Dolby surround play.
In the wide mode and the normal
mode which added the center speaker especially in the center of a front speaker,
in order that the sound which should come out from centers, such as an actor's
words, may orientate to not a synthetic sound but the independent center channel
on either side, a feeling of the normal position of sound, a feeling of
movement, and a feeling of a lively motion are improving.
The phantom mode
when not using the normal mode and center speaker which were suitable when
center speakers were a right-and-left speaker and an equivalent grade and the
optimal wide mode and a center channel were smaller than a speaker on either
side can be chosen as the Dolby prologic.
At a normal mode, a signal of
100Hz or less is distributed and outputted to the right-and-left channel, and
signal regeneration electrically orientated in the center by a directivity
emphasis circuit is performed in phantom mode.
The digital delay system
is adopted as a delay circuit, and the signal to noise ratio and distortion are
sharply improved compared with an analog form.
Delay time can be chosen from
15/20/30msec.
The test tone generating circuit is carried and a fine
level setup can be performed.
Surround mode is carried so that the
software of ordinary stereophonic recording can also enjoy the surround effect.
It is possible to be able to choose surround mode from a hole / stadium /
simulated stereo, especially to use mono-sauce as a false stereo in a simulated
stereo, and to enjoy itself.
The pre-out terminal is carried so that
power amplifier can be extended.
Rec Out Selector has the 2 modes of
Video and Audio, a recording signal can be chosen in the mode of Video and they
can choose a recording signal in the mode of Audio. It can edit with the
combination in these 2 modes, combining freely two kinds of sauce in which the
sound differed from the image. A recording recording signal is outputted to VCR
1 and 2, and a recording signal is outputted to DAT/Tape1, 2, and 3 terminal.
Moreover, to the apparatus which carries input / output both terminals like
VCR or DAT/Tape, the prohibition circuit which prevents the loop of a play and
recording (recording) is built in.
The basic circuit of the
Integrated-Amplifier high-end model kind of DENON is carried in the front as it
is, and the power transistor of fT20 MHz-Pc 150W is used by the single push
pull.
Moreover, a 4.8kg power transformer is carried in the power-source
part.
In order to prevent the mutual intervention between each circuit,
the composition which carried out the separation of each block of a video signal
board, an audio signal board, a power-source part, and a power amplifier part
according to the function by chassis block is adopted.
The
superimposition function which displays the situation of a function or a
function of operation on TV monitoring screen, and the multifunctional enhancer
function to the recording / VCR 1 and 2 of VCR3 while monitoring in which either
of the back recording can be operated are carried.
Moreover, at the time of
power-source on/off by remote control operation, all the functions are held with
a last function memory function at the state in front of the power source off.
The remote control which can control CD player, a cassette deck, etc. of
not only AVC-2000 but DENON is attached. Moreover, it is possible by using
a learning function to register the function of 154 pieces at the maximum,
and to control the television and video of the other company, and other
audiovisual apparatus.
