Pioneer VSA-550

Commentary

This AV amplifier is equivalent to the basic model with many basic functions.

Equipped with Dolby pro-logic circuit.
In order to obtain the same effect as a theater, a dual-center system is adopted, and the sense of orientation and movement is made natural by setting the speaker to the left and right or top and bottom of the screen.
It also has a built-in auto-input balance function that automatically adjusts the balance in real time so that the input signal level matches correctly, greatly reducing crosstalk of each channel and realizing clearer sound image localization.

The front and center channels of the power amplifier are designed to have the same power and quality.
In addition, it uses direct construction that reduces sound degradation by making the signal path the shortest distance, and honeycomb chassis and honeycomb heat sink that have excellent vibration damping characteristics.

Equipped with a soundfield memory that can store adjusted data such as front and rear balance, each channel level, surround mode settings, etc.
It is also equipped with an acoustic memory that can store the tone control settings.

Learning type remote controller is included.

There was a black model in addition to the gold model.
