Commentary
An AV amplifier that supports Dolby Pro Logic and has a 5.1 ch input.
The 5.1 channel input allows for Dolby surround playback via a 5.1 channel DVD player or surround processor with a Dolby digital decoder.
Low-feedback circuits are used for all 5 channels in the power amplifier section, and Motorola 24 bitDSP is used for the DSP processor.
The built-in Cinema Re-EQ (Cinema Re-EQ) circuit allows you to re-correct the recorded sound signal with high frequency emphasis, assuming that the speaker is placed behind the screen.
The D/A converter is equipped with a 20-bit delta-sigma A/D and D/A converter.
There are five surround modes, including the original mode, and you can create your favorite surround by fine-tuning parameters.
With 3-D Bass, you can hear the deep bass from the front / center speakers more clearly.
It features a smart scan controller and a rotary dial controller on the front panel for easy system setup and parameter settings.
Equipped with I. P. M. (Intelligent Power Management) function, when the TV is turned on / off, the power of the amplifier is automatically turned on / off in conjunction with the sound signal of the TV.
A remote control is included.
