FINISHING THE INSTALLATION (CONTINUED)

The StageFront Pro1870LCR and Pro2870LCR models feature Boundary Compensation and Pod Level controls in addition to those for Treble and Midrange levels. These controls are also on the front for acoustic fi ne-tuning after placement, as shown in Figure 8. Adjust these controls as follows:

If a Pro LCR is placed in a cabinet or position where the loudspeaker is closer than

2 to 3 feet from a room boundary, such as a wall, and the sound is ‘boomy’, please switch the Boundary Compensation switch on. You may need to also adjust the Midrange level when using this switch.

The Pod Level control allows you to adjust the level of the Tweeter and Midrange in relation to the woofer(s) of the loudspeaker. If you are getting ‘boomy’ response after adjusting the Midrange level and the Boundary Compensation switch, you may need to increase the level of the Pod in relation to the woofer(s). If you are getting thin or ‘tinny’ response after adjusting the Tweeter level and the Boundary Compensation switch, you may need to decrease the pod level in relation to the woofer(s).

Please remember to also check the settings of your receiver or processor if you cannot achieve satisfactory sound once you have tried adjusting the controls of the loudspeaker.

INSTALLING THE GRILLE

If desired, at each loudspeaker, carefully fi t the grille to its cabinet. Starting with one corner, gently press the grille frame around the loudspeaker’s edge, pushing it in at each of the four recessed holes. When properly installed, the edges of the grille will be nearly fl ush in appearance with the cabinet.

OPERATION

LISTENING AT HIGHER VOLUMES

Achieving a reasonable volume of sound in a large room requires more amplifi er power than it does in a small room. It is possible to turn the volume up so high that the amplifi er runs out of power. This creates “clipping” distortion, which will make treble sound very harsh and unmusical. When you hear harsh-sounding treble from any good loudspeaker, turn the volume down immediately! Those harsh sounds are masking much more powerful ultra-high-frequency sound spikes, which will quickly damage any fi ne loudspeaker. You are much less likely to damage a loudspeaker driven by a large amplifi er because it will be very loud before any clipping distortion is produced.

CLEANING

Clean the StageFront Home Theater Solutions loudspeaker with a dampened soft cloth or paper towel.
