Installation and
Calibration
Move your head from side to side to find
the position where the noise is full left,
and the right ear hears near total silence.
When calibrating right, if your left ear is
in the silent band, the speaker angle is
correct.
To set the Speaker Angle, center yourself symmetrically between the two
front speakers. Turn CAL NOISE on and select LEFT ONLY. The test signal
should sound as though it is coming from off to your left side, well beyond
the left speaker, with near-total silence in your right ear. Still facing forward,
move your head from side to side until the effect is strongest. When you
have found this sweet spot you will notice an almost physical sensation of
silence in your right ear.
Now, select RIGHT ONLY. Again, shift your head from side to side to find
the sweet spot, this time looking for the point where the sound is strongest
in your right ear. Select LEFT AND RIGHT to determine if the sweet spots
from the left and right tests coincide. If they do not coincide, return to the
SPEAKER ANGLE display. If the first sweet spot is to the left of the second,
press MENU ▲ ; if it is to the right, press MENU ▼.
If your normal listening position is not centered between your two front
speakers, once you have corrected the speaker angle setting, you can
"move" the sweet spot to that position. To do this, select LISTENER POS and
use MENU ▲ and ▼ to move the effect. As you adjust the position, the
display will indicate motion to the left of center (L001,L002,L003...L127),
CENTER, or to the right of center (R001,R002,R003...R127). The numbers
represent approximately 1/3", but are provided primarily as a general
reference.
Panorama is now calibrated. Press DONE repeatedly to step back to the
main setup menu.
If the two silent bands are too close, lower
the Speaker Angle; if they are too far
apart, raise the Speaker Angle.
