Chamber
In the MPX 100, the stereo Chamber
program produces an even, relatively dimen-
sionless reverberation, with little change in
color as the sound decays. The initial diffu-
sion is similar to the Hall program, but the
sense of space and size is much less obvi-
ous. This characteristic, along with the low
color of the decay tail makes Chamber useful
on a wide range of material. It is especially
useful on spoken voice, giving a noticeable
increase in loudness with very low color.
Historically, recording studio chambers were often oddly shaped rooms with a
loudspeaker and set of microphones to pick up the ambience in various parts of the
room.
