AV Control Center with Dolby Surround
The ADM (Adaptive Delta Modulation) digital surround system is used in order to enjoy higher quality surround sound. By switching the control signal to the digital delay IC, the delay time can be selected from three stages of 15, 20, and 30 ms.
You can choose from three surround modes according to the source.
Dolby Surround Mode reduces noise by decoding and playing back the encoded source at the time of recording. The surround signal adds a 15-30 ms delay to the L/R signal and uses a Dolby B-type noise reduction circuit to improve SN. The mono structure of the surround signal enhances the sense of localization of the sound behind the sound field.
Simulated Surround mode is a mode that gives a pseudo surround effect to a monaural program source. A signal obtained by adding or subtracting the L + R signal and the delayed signal is output to the surround L/R channel to achieve natural surround sound.
In the stadium mode, a surround effect is added to the stereo signal, and the L/R signal and the delayed signal are respectively output to the surround L/R channel to reproduce the presence of a stadium.
The VCR2 is equipped with an S jack for higher picture quality sources.
In addition to the AV4 system, an audio Line 5 and a video system are equipped with input / output terminals.
It uses an electronic volume that can be operated by a remote control.
It uses parts that take sound quality into consideration such as honeycomb chassis, large insulators, and very thick power cords.
It comes with an AV programmable remote controller with a learning function that can control video, TV and audio equipment.
