Parameters for the STR-GX 900ES
This receiver uses digital signal processing to reproduce the
sound effects of various listening environments, such as a
concert hall. Three sound elements contribute to this effect:
direct sound, early reflection and reverberation. The
following diagrams show how each sound element work.

You can adjust the parameters to control direct sound, early
reflection, and reverberation. The following diagrams show
how these three elements are controlled in each parameter.
Room Size Simulation (ROOM SIZE)
Before sound reaches our ears, it is reflected many times
between the left and right walls, ceiling, and floor. Ina large
room, sound takes-more time to bounce from one surface to
another than in a smaller room.
The room size parameter controls the spacing of early
reflections to simulate the room size. The S indicator on the
display signifies a small room, the L indicator signifies a
large room, and the middle point designates a standard
room size.
