Commentary
AV amplifier equipped with D. D. S. C. in pursuit of high sound quality.
The basic configuration of DENON's surround circuit is a combination of an analog prologic decoder (directional enhancement circuit) and a digital signal processing circuit (DSP). We have further advanced this method. The D. D.D. S. C. (Dynamic Discrete Surround Circuit) circuit uses separate DSPs, A/D converters, and D/A converters to perform A/D, DSP, and D/A processing, which was conventionally done in one chip. This improves signal processing capability and performance.
In addition, by adopting newly developed IC in the pro-logic decoder, low distortion rate and high S/N are realized compared with conventional equipment.
Since the analog and digital sections can be clearly separated, it is possible to minimize the effect of digital noise on the analog circuit.
We have newly developed and adopted ICs for on-screen displays.
An icon type character is used to display the current operation status on the screen in an easy-to-understand manner.
The power amplifier uses a discrete configuration for each channel of the front and center.
In order to reproduce CD players etc. with higher sound quality, it is equipped with a source direct function which bypasses each tone balance control circuit and transmits the signal to the power amplifier through a separate system.
It is equipped with a AVSE circuit to amplify the low range that deepens the reality of AV sound and to realize more powerful sound reproduction.
In addition, it is equipped with a cinema equalizer that can clearly and elegantly reproduce the dialogue of a person who has been recorded for movie software and other theaters with high frequency emphasis.
It is equipped with a multi-source function equipped with a dedicated terminal for outputting video and audio input different from the video and audio input being reproduced in the set body.
Equipped with a personal memory function, it is equipped with 3 modes of personal memory function that can store and recall combinations of input source and surround mode (including DSP parameter, AVSE and CINEMA ON/OFF).
Equipped with a total of 11 surround modes.
Four audio devices and four AV devices can be connected to the input terminal, and a gold-plated terminal is used.
The front speaker can be switched between A and B.
Pre-out and main-in terminals are mounted.
It uses a large FL display that is easy to see.
It comes with a remote controller equipped with a pre-memory function for storing operation codes of major domestic manufacturers, a system call function, a system remote function, and a learning function.
