Commentary
An AV amplifier equipped with digital Dolby Pro-logic circuit.
Equipped with a Dolby Pro Logic circuit that digitizes the directional enhancement control, delay, modified B-type noise reduction, etc.
The delay time can be adjusted from 16 ms to 30 ms in 2 ms steps. The effect can be adjusted according to the installation conditions. The center channel can also be output to two speakers using the dual-center method.
Built-in sound field control by DSP with preset sound field.
Sound field data of famous performance venues obtained by a unique computer simulation method is stored in digital memory. Five types of music can be enjoyed : Hall, Jazz, Disco, Church, and Theater.
In addition, it is equipped with Simulated Surround which can enjoy stereo feeling even in monaural.
The power amplifier section is designed to drive the front three channels with an amplifier of the same power and quality.
We are also working to improve sound quality by introducing technologies such as direct construction with the shortest signal path, honeycomb frame with excellent vibration dispersion and damping, and honeycomb heat sink to shut out external vibration.
It has a built-in base synthesizer circuit that automatically creates a deep bass of 1/2 the frequency from the low-frequency signal component contained in the source. This increases the impact of the bass.
It is equipped with an on-screen display function that displays information such as the currently selected source, dubbing settings and surround operation on the TV screen.
In addition, it is equipped with a function backup that retains the selector regardless of the power supply of the body.
Equipped with 5 ch pre-out and subwoofer output.
Learning type remote controller is included.
There was a black model in addition to the gold model.
