When calibrating right, if your left ear is in the
silent band, the speaker angle is correct.
If the two silent bands are too close, lower the
Speaker Angle; if they are too far apart, raise
the Speaker Angle.

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.

The SPEAKER ANGLE, displayed in degrees, adjusts for wide or
narrow speaker spacing (relative to the listening position). For the two
canceling signals to arrive at both ears at the same time you must be
centered precisely between the speakers. It will be easiest to calibrate
this parameter if you start equidistant from the two front speakers, even
if this is not your normal listening position. Once you have heard the
effect and set the speaker angle, the Listener Position parameter will
allow you to “move” the effect to your customary listening position.
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
▲ ; if it is to the right, press ▼ .
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
▲ 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.
