Customizing Sound Fields Settings and Adjustments The SURROUND menu contains parameters that let you customize various aspects of the current sound field. The settings available in this menu are stored individually for each sound field. p Effect Level SURR.EFFECT XXX% Initial setting : (depends on sound mode) This parameter lets you adjust the "presence" of the current digital cinema sound surround effect. p Wall type WALL S____|____H Initial setting : midpoint When sound is reflected off soft material, such as a curtain, the high frequency elements are reduced. A hard wall is highly reflective and does not significantly effect the frequency response of the reflected sound. This parameter lets you control the level of the high frequencies to alter the sonic character of your listening environment by simulating a softer (S) or harder (H) wall. The midpoint designates a neutral wall (made of wood). p Reverberation REVERB S____|____L Initial setting : midpoint Before sound reaches our ears, it is reflected (reverberated) many times between the left and right walls, ceiling, and floor. In a large room, sound takes more time to bounce from one surface to another than in a smaller room. This parameter lets you control the spacing of the early reflections to simulate a sonically longer (L) or shorter (S) time. The midpoint (0) designates a standard room with no adjustment. p Screen depth SCREEN DEPTH [MID] Initial setting : MID In a movie theater, sound seems to come from inside the image reflected on the movie screen. This parameter allows you to create the same sensation in your listening room by shifting the sound of the front speakers "into" the screen. • The screen depth can be set to OFF, MID, or DEEP. • DEEP provides the greatest amount of screen depth. p Virtual speakers VIRTUAL SP [ON] Initial setting : ON Allows you to turn the virtual speakers created by the CINEMA STUDIO EX. A, B, C and SEMI-CINEMA STUDIO EX. A, B, C sound fields off or on. p Rear reflection enhancer REAR ENHANCER [ON] Initial setting : ON This is a setup that adds the effect of a broader sound obtained from the sound of the surround channel even when the surround channel sound is monaural. This setting operates in CINEMA STUDIO EX. A, B, C and SEMI-CINEMA STUDIO EX. A, B, C. • When ON is set, the effect is automatically applied to sources recorded in Dolby Pro Logic or Dolby Digital [2/1], [3/1] surround channel • When OFF is set, there is no effect added. p Bass adjustment (Level/Frequency) BASS +XXdB BASS XXXHz Unlike the equalizer in the equalizer menu (which allows you to individually adjust the overall sound quality of each set of speakers) these parameters allow you to individually adjust the tonal quality of each sound field. 1 Press the cursor buttons ( or ) repeatedly to select the level (dB) or frequency (Hz). 2 Turn the jog dial to adjust. Repeat until you achieve the sound you desire. • The level can be adjusted ±10 dB in 1 dB steps. • The frequency can be adjusted from 99 Hz to 1 kHz in 21 steps. p Midrange adjustment (Level/Frequency) MID +XXdB MID XXXHz Adjust as described in "Bass adjustment". • The level can be adjusted ±10 dB in 1 dB steps. • The frequency can be adjusted from 198 Hz to 10 kHz in 37 steps. p Midrange bandwidth MID [WIDE] This parameter lets you adjust the width of the midrange band. • "WIDE" provides a wide band centered on the selected frequency, for general adjustments. • "MIDDLE" provides a normal band. • "NARROW" provides a narrow band centered on the selected frequency, for specific adjustments. p Treble adjustment (Level/Frequency) TREBLE +XXdB TREBLE XXXHz Adjust as described in "Bass adjustment". • The level can be adjusted ±10 dB in 1 dB steps. • The frequency can be adjusted from 1.0 kHz to 10 kHz in 23 steps. 41
