Ambience

The Programs:

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 with only two loudspeakers, Ambience 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 4 and progressively lower

for Programs 5 and 6. It will be easier to hear exactly what the parameters

do if the effect level is temporarily turned all the way up.

The LIVENESS parameter adjusts the amount of recirculation within the

program. 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 programs, which

are more effective at simulating very live spaces.

Liveness

ROOM SHAPE selects one of two basic hall shapes. Refer to Chapter 5:

Theory and Design, for a discussion of the properties of the two.

Room Shape

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 adjusted as high as possible without making the

extra speakers individually audible.
