Ambience
Ambience generates the appropriate early reflections for stereo simulation
of one of six different halls — one rectangular hall and one fan-shaped hall
in small, medium and large sizes — and sends the reflections to the side and
rear speakers. For systems without side speakers, Ambience also incorpo-
rates a version of Panorama that will spread the stereo image and add the
reflections it generates to the expanded sound stage.
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. This control should be adjusted as high as
possible without making the extra speakers individually audible.
Ambience Parameters
ROOM SHAPE selects one of two basic hall shapes, rectangular or fan. Refer
to the Theory and Design booklet for a discussion of the properties of the
two.
ROOM SIZE allows you to change the room size in fine graduations within
the overall hall size you have selected. For convenience, the hall size is
denoted by length in meters.
The LIVENESS parameter adjusts the amount of recirculation within the
mode. The higher the value, the more reflective the surfaces of the simulated
space and the longer the sound will take to decay. At very high values the
decay is audibly less smooth than in the Reverb modes, which are more
effective at simulating very live spaces.
ROLLOFF mimics the absorption of the air in the hall and its initial value is
therefore more pronounced (the rolloff begins at a lower frequency) the
larger the space.
PANORAMA EFFECT adjusts the strength of the signal used to expand the
stereo image outward from the front two speakers. It is only needed when
side speakers are absent. (If the system is configured without side speakers,
the signal normally sent to the sides will be mixed into the front outputs.)
