Commentary
AV amplifier with 5 ch discrete configuration and Dolby Pro Logic IC.
High power is realized by making each amplifier of front, center and rear into a discrete configuration.
The Dolby Pro Logic Decoder uses an IC developed in collaboration with PMI, a U.S. semiconductor manufacturer.
Compared with conventional equipment, it has excellent SN ratio and distortion factor, and excellent performance is realized by improving sound quality.
In order to eliminate interference between video and audio systems, both sections are separated from the power supply.
This results in a purer sound quality.
In order to always keep the separation of each channel of the prologic in the best condition, it is equipped with an auto input balance which compensates for the level difference between channels in real time.
In addition to the Dolby Prologic mode of 4 modes of wide / normal / phantom / 3 ch, 4 modes of hall / simulated / スペクテリア / studio are installed as general surround mode, so you can enjoy the surround effect even with stereo recording source.
Since the delay time can be selected every 5 msec, it can be adjusted according to the type of listening room and software. In addition, the level can be set according to the listening condition by using the test tone generation circuit.
Four audio devices and five AV devices can be connected to this terminal.
It is also equipped with a mono-out terminal that is convenient for sub-woofer connection for bass enhancement.
A preset memory function for surround sound can be used to store the rear, center level and delay time of each surround sound.
Wireless remote control is included.
