In addition to the “TYPE” parameter which selects the subprograms 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 “3-2. DESCRIPTIONS OF THE DIGITAL SOUND FIELD PARAMETERS” on page 42 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 Parameter + (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 settings on this unit, will return to their initial values or conditions.
