SPEAKER ANGLE compensates for differing distances between your front
speakers. It affects only the Panorama Effect and is only needed when side
speakers are absent. The Speaker Angle can be set to the value reached in
the setup procedure on page 13, but the program may also work well at
lower values.
The image expansion will be strongest at the one location in the room for
which the program has been calibrated (See page 10). It will diminish
somewhat as you move forward or back from that location and more
rapidly as you move from side to side.
The procedures for naming a new version of the program (SET PROGRAM
NAME) and storing it in one of the User registers (MEMORIZE PRO-
GRAM) are described on page 36.
EFFECT LEVEL adjusts the loudness of the side and rear speakers. When
there are no side speakers, it adjusts the amount of ambient signal mixed
into the main loudspeakers. EFFECT LEVEL is the most important user
adjustment in the Concert Hall mode, and has been given its own button on
the remote. It should be set as high as possible without making the extra
speakers individually audible.
ROOM SIZE allows you to change the room size in fine gradations. For
convenience, the hall size is denoted by length in meters.
Mid RT
MID RT (Midrange Reverberation Time) is the time required for midrange
sounds to decay 60 dB in level. Your choice the size of the synthesized space
determines both the initial value and the available range of MID RT.
