The Reverberation program differs from Ambience in that it does not simulate the early reflections of specific halls, but emphasizes rich, smooth reverberant decay in small, medium or large spaces. It works well for simulating a space with a long reverberation times relative to its size, such as a reverberant chamber, church or the like. For systems with only two loudspeakers, Reverb also incorporates a version of Panorama that will spread the stereo image and add the reflections it generates to the expanded sound stage.

The initial EFFECT LEVEL is highest for Program 7 and progressively lower for Programs 8 and 9. It will be easier to hear exactly what the parameters do if the EFFECT LEVEL is temporarily turned all the way up.

* 0 if side speakers are specified

Effect Level EFFECT LEVEL adjusts the loudness of the side and rear speakers. When there are no side speakers, it adjusts the amount of ambient signal mixed into the main loudspeakers. EFFECT LEVEL is the most important user adjustment in AMBIENCE and REVERB, and has been given its own button on the remote. It should be set as high as possible without making the extra speakers individually audible.
