DC-1 Digital Controller

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.

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.
