OPTIMIZING PERFORMANCE

It is highly recommended that you make front-panel control adjustments before installing the grille. Experiment with settings and carefully listen to ensure that the proper adjustments have been made.

To optimize the P81 and P941 for best performance:

1.Refer to the Loudspeaker Placement section on page 8 for information about loudspeaker installation.

2.Set the High-Frequency Level control to 0 (different listening rooms may require other High-Frequency Level control settings).

3.Set the Low-Frequency Boundary Compensation control to the appro- priate position.

•Select the “off” setting if the speak- er is mounted at least 4 feet away from adjacent walls or boundaries.

•Select the “on” setting if the speak- er is mounted close to one (or pos- sibly two) or more adjacent walls or boundaries. In the “on” position, system output is reduced below approximately 400Hz to offset the increased low-frequency support due to the boundary.

4.Begin playback of a familiar music or film source.

Set Listener Axis Switch to “High” if listening position is at tweeter level or above.

5.Listen from the primary listening position, increasing volume to a comfortable level.

6.Adjust the High-Frequency Level con- trol on each P81 or P941 to change high-frequency balance and timbre.

7.Adjust the Listener Axis control depending on the position of the primary listening location. Refer to Figure 19.

•Select the “high” (up arrow) setting if the speaker is mounted so that the listener is above the tweeter level.

•Select the “on axis” setting if the listener location is directly on axis.

•Select the “low” (down arrow) set- ting if the speaker is mounted so that the listener is significantly below the tweeter.

When the loudspeaker has been mounted upside-down, (with the woofer higher than the tweeter), refer to Figure 19. The listener axis control settings function in the opposite manner as normal operation:

•Select the “low” setting if the speaker is mounted so that the lis- tener is at tweeter level or above.

•Select the “high” setting if the speaker is mounted so that the listener is below the tweeter.

Set Listener Axis Switch to “on axis” if listening position is directly at tweeter level.

8.Set the High-Frequency Tilt switch to “+” if your listening position is far off the tweeter axis; otherwise, leave it at “0.”

9.Repeat these steps to optimize per- formance of the second P81 or P941.

NOTE: For best results, set the High- Frequency Level, High-Frequency Tilt, and the Listener Axis controls to the same positions on both loudspeakers.

Painting the Frame

Proper surface preparation is critical for best results. Use spray, roller (smooth), or a pad to apply the paint. Clean and prime the frame surface prior to painting.

1.Place frame on a protected work surface.

2.Install plastic paint mask (included) into the frame.

3.Clean front edges of frame face by gently rubbing with a soft rag damp- ened with rubbing alcohol.

4.Apply one coat of white or neutral color water-based primer and let dry.

5.Apply one to two coats of paint for desired finish.

Set Listener Axis Switch to “Low” if listening position is below tweeter level.
