Second-hand original Japanese Denon 3805 home theater amplifier "Silver"
220V voltage
Machine without grinding, new appearance and fineness
Equipped with universal remote control
Rate 180W×7(6 ohm JEITA), Built-in Dolby Digital Pro IIx, Dolby Digital EX, dts-ES and HDCD decoding, etc. When listening to music, users can use the Pure Direct mode to enjoy two-channel music with the most direct transmission, so regardless of playing music or movie software All have good sound quality.
After seeing the appearance of AVR-3805, the most intuitive feeling is that the area of ??the data display on the AVR-3805 panel has become much larger. At the same time, the many function keys of the original AVR-3803 on the panel are almost all hidden for activities. Behind the hinged door, only a few of the most commonly used function keys are kept, and the overall layout is more concise, which improves the image of the power amplifier.
In terms of sound effects, AVR-3805 has many listening modes. In addition to the familiar DTS, Dolby Digital, Dolby Pro Logic and their various related modes, it also adds the newly launched Dolby Pro-Logic IIx mode. Process the two-channel source into 7.l channel output. The DSP sound field mode includes 10 kinds of WIDESCREEN, SUPER STADIUM, ROCKARENA, JAZZ CLUB, VIRTUAL, MATRIX, VIDEO GAME, 5CH/7CH STEREO, MONO MOVIE and CLASSIC CONCERT, no matter which type of program is played, you can find the corresponding The DSP mode increases the sense of presence and entertainment.
In terms of sound quality, the built-in HDCD decoding function of AVR-3805 makes enthusiasts feel excited. In addition, AVR-3805 also has PURE DIRECT.(Pure pass-through)With DIRECT(Through)Mode: When switching to PURE DIRECT(Pure pass-through)At this time, the video circuit, digital audio processing circuit, and data display circuit in the machine will all be turned off, leaving only the operation of the analog audio circuit to improve the purity of the sound. If switch to normal DIRECT(Through)Status, the sound signal will skip the Tone Control processing circuit, and other aspects will still work as usual.
On the digital signal interface, in addition to the conventional digital coaxial and optical fiber terminals, this machine is also equipped with the third-generation DENON Link interface. This interface must be used with signal source equipment that also has the third-generation DENON Link interface. , It can transmit digital signals including DVD-A and SACD.
The advanced DENON models all have the processing function of AL24, and have also been upgraded on the AVR-3805. The function of AL24 is to convert ordinary two-channel LPCM digital signals(E.g. CD)Increase to 192kHz/24bit to get better linearity and dynamics and improve playback sound quality. The AVR-3805 uses“”The AL24 Processing Plus version can not only process the two-channel LPCM signal, but also correspond to the multi-channel DVD-A signal when using the DENON Link. The LPCM signal is fully upgraded to 192kHz/24bit.
Since the AV amplifier can reproduce different scenes in the movie software, the AVR-3805 especially worked hard in this regard, such as adding Denon''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s newly developed D.D.S.C.(Dynamic Discrete Surround Circuit)With the Digital EX circuit, the manufacturer has greatly enhanced the ability of the AV amplifier to play back multi-channel surround sound effects through different high-performance components, including A/D and D/A converters, DSP processors, etc. At the same time, AVR-3805 uses the brand new SHARC(ADI ADSP 21266)The 32bit floating point arithmetic chip makes it twice as powerful as the old Melody 100 chip in processing Dolby Digital, dts signals and DSP, so it can reproduce the surround sound effect more realistically.
Excellent materials to reduce interference
In addition to the improvements in digital technology, the AVR-3805 uses very good materials in the amplifier, especially heavy-duty transformers, which can effectively eliminate the signal noise in the machine. At the same time, the shock-absorbing materials around the ACG core and the double-layer base case effectively help reduce interference to the signal, and the large filter capacitor also directly improves the sound quality during playback.
