DENON AVC-3030 | AVC-3030: 150,000yen(around the 1991 time) | AVC-3030G:158,000yen(around the 1992 time) |
The AV amplifier which adopted the New Super Optical Class A circuit, and aimed at the play of a purer sound.
The New Super Optical Class A circuit original with DENON is carried in the power amplifier part for a front and centers. It is possible to amplify by this circuit using the non switching Class-A system which carries out magnification operation of the level of listening power as a pure Class-A, and has an effect in the improvement of crossover distortion or switching distortion at the time of the Oide power. The bias control circuit of high-speed operation is performing control of the magnification system by the size of an input level, and the optical element is used for the control signal transfer in a power transistor bias circuit from this bias control circuit. While this eliminates a mutual interference completely "between bias controlling circuits" with a "main signal system", high speed-ization of bias control is realized. Moreover, the power transistor of fT20MHz and Pc150W is adopted as an output stage.
DENON has adopted as a Dolby prologic decoder part IC sorted out specially uniquely. While this realizes a low distortion and high S/N, the improvement of a dynamic range is realized.
A "theater" begin the Dolby prologic and according to an adaptive matrix and a DSP acoustic field simulation, the "live",The "mono-movie" which can enjoy DSP presence with four parameters, the "classic concert", the "lock concert", the "church", and the "stadium" are carried. Moreover, each mode can be finely adjusted according to liking, and can make the acoustic field united with its image. Furthermore, the matrix which can enjoy a speaker matrix effect is also carried.
a power-source part -- high -- the efficiency regulation and the toroidal transformer which enables reduction of the leakage flux are carried.
Low-pass is amplified and the AVSE circuit which realizes a more powerful surround play is carried. Moreover, the cinema equalizer which improves the movie software which emphasized and recorded the person's words to theaters is carried.
The direct function by mechanical relay is carried in the CD/VDP audio circuit. The transmission system from an input to a preamplifier part output is limited to the shortest, and high-quality sound-ization at the time of 2ch stereophonic reproduction is attained.
The video selector corresponding to a wide aspect interface is built in, and automatic detection of the field angle size of a standard image and a Hi-Vision image is carried out, and it corresponds. Moreover, broadband video amplifier is also built in and the four-channel discrete audio input is also carried.
Five audio inputs and five voice + video inputs are carried. Moreover, the Rec out selection function is carried.
The simulcast play function, and an ounce clean display function and an auto input balance function are carried.
The study remote control with a pre-memory function which has memorized the operation cord of AV component stereo of DENON, main home manufacturers' LD player, a videocassette recorder, and television is attached.
Besides AVC-3030 of black calla, there is AVC-3030G of the gold-collar with side wood.
