70 / 114 page  signal contains the spatial information that al- lows us to perceive sounds from coming all around and the directional cues that we use to determine the localization of those sounds. Turning up the Space control increases the amount of corrected directional information, re- stores the proper localization of the original sounds, and expands the width of the overall sound stage. Turning down the Space control re- sults in having no processed difference signal component and thus limits the intensity of these effects. When SRS 3D sound is first turned on (3DEN in C3), the Space control (SPC3-SPC0) should be adjusted before the Center control. Space should be set to approximately 75% (SPC3-0 = 0011, or -4.5 dB) with the Center control set to 50%. As the level of Space is increased, the sound stage expands both in width and depth. The proper lis- t en i ng l eve l is subj ect ive a nd pro gram dependent. If centered sound information (such as vocals) seem too low as a result of the Space control setting, they can be adjusted using the Center control. If adjusting the Space control yields no change in the sound image, the input signal is probably mono and the Mono-to-Stereo switch, 3DM, should be enabled. SRS Center Control The SRS Center adjustment, CTR3-0 in C2, de- termines the amount of sum signal (L+R) that is added to the final left and right digital signals going to the DACs. The sum signal contains in- formation common to both channels that is intended to appear in front or at the center of the sound stage. Vocals, dialog, solo instruments, bass, and kick drums are examples of sounds that are often placed at the center. When SRS 3D sound is first turned on (3DEN in C3), the Space control should be adjusted before the Center control (CTR3-0). Space should be set to approximately 75% with the Center con- trol set to 50% (CTR3-0 = 1000, or -12.0 dB). Turning up the Center control emphasizes the centered sounds so that their perceived level is increased and they are brought out and into the center of the room. Once Space is set, the Center control should be adjusted to provide a pleasant balance between the ambient sounds and the centered sounds.
