Description
 
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.
