Commentary
An AV amplifier that uses a Dolby pro-logic decoder and 5-channel amplifier configuration.
Equipped with a Dolby Pro Logic Surround Decoder.
This decoder uses a directional enhancement circuit and realizes 4-channel L/C/R/S playback. In the conventional 3-channel L/R/S playback, the sound image at the center is a composite of Lch and Rch. By playing back the dialogue component from the center speaker, it is possible to perform stereoscopic playback in which the sound image moves in accordance with the movement of the cast.
Four surround circuits are built in.
Dolby Pro Logic Surround is compatible with Dolby Encoded Software, Theater is effective for stereo recording software, Stadium is ideal for sports and live, and Simulated creates surround sound by creating pseudo rear component from monaural source.
Auto Input Balance is used to automatically adjust the input balance.
Equipped with center mode control function, 3 patterns can be set corresponding to the variation of the front center channel.
The normal mode is a mode in which the center is assumed to be used with a small speaker. The signal component of 100 Hz or less is cut off is sent to the center, and the cut component of 100 Hz or less is distributed to the left and right channels of the front.
In the wide mode, the center channel is assumed to use speakers of the same grade as the left and right channels. The center output is sent directly to the center.
Finally, the phantom mode is a mode that assumes a situation where the center speaker is not used. The center output is equally distributed to the left and right front speakers.
Equipped with a digital delay circuit, it can be adjusted in 1.5 ms steps in the range of 0 to 30 ms (15 to 30 ms for Dolby Pro Logic Surround mode), allowing you to enjoy the most effective delay time.
Equipped with a test tone circuit, the balance of each channel can be adjusted.
You can set each channel to the same volume by displaying the on-screen function and the composite sound output from the noise sequencer.
Five amplifiers are used : two front channels, center channel, and two rear channels.
During surround bypass, only the front stereo is played back.
Equipped with a source direct switch, the signal can be directly connected to the power amplifier at the shortest distance.
A total of 12 input terminals, audio Route 6 and AV Route 6, are installed.
The S pin is also equipped with four input channels and an output Route 3.
Gold plated plugs are used for the input / output terminals.
It is equipped with a wide-band video amplifier with horizontal resolution of more than 800 lines.
This amplifier compensates for the matching loss (-6dB) at the video input, sets the output impedance to 75 Ω, and amplifies video signals with a horizontal resolution of more than 500 lines such as ED - β and S-VHS without loss.
Equipped with a VIDEO1 dubbing selector, it is possible to record back images.
It has a monaural output terminal for the subwoofer and a pre-out terminal for the rear.
Adapter input / output terminal is mounted, and external adapter can be added.
Motor drive type is used for volume.
Φ 60 new structure large insulator has been adopted.
Equipped with Kenwood serial terminal equipment and a serial terminal capable of remote control operation.
A mass storage remote controller with a maximum storage key count of 145 is included.
