SPEAKER ANGLE is the angle between the main speakers as seen from the listen- ing position Ñ here it is about 60°. LIS- TENER POS allows you to adjust for an offset listening position.

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.
If the two silent bands are too close, lower the Speaker Angle; if they are too far apart, raise the Speaker Angle.

CAL NOISE is a special digitally generated signal to aid in calibrating the Speaker Angle and Listener Position parameters. Note that in all cases, sound will actually be produced by both front loudspeakers. The adjust- ments affect the perceived directionality of the sound.
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 ÒmoveÓ 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
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 ap- proximately 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.
