To calibrate the PANORAMA listening mode:

1.Remove all obstructions between the primary listening position and the speakers.

2.Make sure the distances between the primary listening position and the speakers are properly measured. To do this, select one of the following options:

•Select the AUTO SPEAKER SETUP menu DISTANCES option to have the SDP-40 automatically calibrate speaker distances.

•Measure the distance between the primary listening position and the front baffle of each speaker. Then, set the corresponding SPEAKER DISTANCES menu parameters to the closest available value.

3.Sit in the primary listening position. If the primary listening position is not centered between the front left and right speakers as shown in illustration 5-B (above), set the LISTENER

POS parameter to compensate for the difference. Each increment within the –127 to +127 parameter range represents about one-third of an inch. Refer to the illustrations above for more information.

4.Set the SOURCE parameter to RIGHT.

5.Begin playback of the external calibration source.

6.When playback of the external calibration source is in progress, set the SPEAKER ANGLE parameter so the sound is not heard in the right ear.

7.To confirm the LISTENER POS and SPEAKER ANGLE parameter settings, set the SOURCE parameter to LEFT & RIGHT. If the PANORAMA listening mode has been properly calibrated, the sound should be perceived to come from all around the primary listening position. If this does not occur, begin again with step 1.
