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.
