Pioneer VSA-900

Commentary

The AV control center features a 5-amp configuration with a center amplifier and Dolby Pro Logic Surround.

Equipped with active matrix Dolby Pro-Logic Surround and built-in directional enhancement circuit (steering logic), crosstalk from adjacent channels is greatly improved, and sound field reproduction with a sense of spaciousness and sense of direction and orientation are obtained.

Equipped with four center channel modes.
In the Normal mode, the signal of 100 Hz or less, which has little effect on orientation, is distributed to the left and right stereo channels. The center channel is in a position where 100 Hz or less is cut off, and 100 Hz or less is output from both sides simultaneously, so that a small speaker can be used for the center.
The Wide mode is a suitable position when the center channel can be used with the same speakers as the left and right channels. It outputs everything from low to high frequencies on the center channel.
Phantom mode is used when the center speaker is not used, and the center channel signal is equally distributed to the front L/R channels.
OFF is the surround balance adjustment position.

Surround mode is also installed in addition to Pro-Logic.
In Stadium mode, you can enjoy the sound field effect with reverberation sound and a sense of surround sound spread widely around the surroundings.
Simulated Surround mode is also effective for monaural sources, simulating the reflection and reverberation of live houses and concert halls, and varying the depth of the space depending on the delay time.
In Studio mode, the rear speaker outputs L/R without delay time, which is particularly useful in small rooms.

The Route 3 of VCR1, VCR2 and VDP is equipped with high-quality S connector.

It is equipped with input / output of 7 AV control systems, audio control Route 6, and visual control 1 system.

The volume is equipped with a motor drive electric volume that can be operated by a remote control.

In pursuit of high sound quality, parts such as honeycomb chassis, large insulator, and oxygen-free copper power cord are used.

To bring out the quality of CD, it is equipped with CD direct input.

It is equipped with a sound field memory that can store each sound field such as front balance, rear balance, level and surround mode.

It comes with an AV programmable remote controller with a learning function that can operate VTR, TV and audio equipment with one remote controller.
