In addition to the “TYPE” parameter which selects the sub-
programs within each sound field program (e.g. “Hall A in Europe”
and “Hall B in Europe” for program 1, “CONCERT HALL 1”), each
program also has a set of parameters that allow you to change the
characteristics of the acoustic environment to create precisely the
effect you want. These parameters correspond to the many natural
acoustic factors that create the sound field you experience in an
actual concert hall or other listening environment. The size of the
room, for example, affects the length of time between the “early
reflections”—that is, the first few widely spaced reflections you
hear after the direct sound. The “ROOM SIZE” parameter provided
in many of the DSP programs alters the timing between these
reflections, thus changing the shape of the “room” you hear. In
addition to room size, the shape of the room and the
characteristics of its surfaces have a significant effect on the final
sound. Surfaces that absorb sound, for example, cause the
reflections and reverberations to die out quicker, while highly
reflective surfaces allow the reflections to carry on for a longer
period of time. The DSP parameters allow you to control these and
many other factors that contribute to your personal sound field,
allowing you to essentially “redesign” the concert halls and rooms
provided to create custom-tailored listening environments that
ideally match your mood and music.
Refer to “DESCRIPTIONS OF THE DIGITAL SOUND FIELD
PARAMETERS” on page 60 for a description of what each
parameter does, how it effects the sound, and its control range.
1. With the desired program selected, press the Parameter Select
(
▼
▼
) key on the remote control unit once. This will recall the next
parameter after the program type. In the case of the CONCERT
HALL 1 program, for example, this would be the INIT. DLY
parameter. You can continue pressing the Parameter Select (
▼
▼
)
key to select other parameters in sequence. Press the Parameter
Select (
▲
▲
) key to scroll upward through the parameter list.
2. When the desired parameter has been recalled, use the
Par (increment) and – (decrement) keys to change its
value to create the effect you want. + increases the value of the
selected parameter, and – decreases the value of the selected
parameter. In both cases you can hold the key down for
continuous incrementing or decrementing. The display will pause
for a moment at the initial value of the parameter as a reminder.
(On the monitor screen,
*
mark at the head of parameter name
disappears at the initial value of the parameter.)
NOTE: Parameter edits made in this way will remain in effect even
with power cut due to power failure or the power plug
disconnected from the AC outlet for up to about two weeks, after
which all parameters, as well as other adjustments or setting
changes on this unit, will return to their initial values or conditions.
