PARAMETER CONTROL
WHAT IS PARAMETER CONTROL?
This processor provides 24 preset programs (16 Sound Fieid Control,
8 SURROUND)
of sound fields ideal for any genre of music and any
concert setting. When listening to a music source using the preset
programs, however, you may feel that you want a more spacious sound,
or a slightly more "'live'' sound. By changing the parameters (i.e. the
elements that make up a sound field) of a preset program, you can create
a sound field with the exact qualities you are looking for.
DESCRIPTIONS OF THE DIFFERENT PARAMETERS
The following are the six parameters.
(The parameter settings vary
depending on the program)
1. INITIAL DELAY
This can be controlled in the Sound Field Control mode.
As shown in fig. (a), the time delay between the direct sound @, and
the first reflected sound @) to reach the ear can be adjusted. This gives
you a expansive, spacious sound.
2. ROOM SIZE
This can be controlled in the Sound Field Control mode. {This does not
include the HALL 4, ROCK 2, ROOM 2, CHURCH or DELAY programs).
As shown in fig.(a), the delay between the early reflections @, @, ®,
and ©) is adjusted to change the apparent size of the sound field.
3. LIVENESS
This can be controlled in the Sound Field Control mode. (This does not
include the HALL 4, ROCK 2, ROOM 2, CHURCH or DELAY programs)
As shown in fig.{a}, the decay rate of early reflections, that is, the degree
of loss in intensity of ©, @, and @ compared to @), is adjusted to
recreate the ''live'' feel of a performance. A slower decay rate gives
you a more "'live'' sound.
4. REVERB TIME
This can be controlled in the HALL 4, ROCK 2, ROOM 2, and CHURCH
programs in the Sound Field Control mode.
As shown in fig.{b), subsequent multiple reflections, or reverberations,
reach the ear of the listener from all directions. The time it takes for
the reverberation sound to decay can be adjusted to change the
atmosphere of the acoustic environment for a richer sound.
5. H.F.REVERB
This can be controlled in the HALL 4, ROCK 2, ROOM 2, and CHURCH
programs in the Sound Field Controi mode.
The reverberation time of higher frequencies can be adjusted so that
they decay faster than lower frequencies. This produces a sound field
with a much more natural feel.
6. P. FRONT EQ, REAR £Q
P, FRONT and REAR signal equalization can be carried out regardless
of type of program.
