Verifying Phase
When proper polarity is not maintained, the speakers play at the opposite ‘time’ from each other, or out of phase.
The result is audio with lack of bass and vocals that sound thin or distant. If during or after calibrating your receiver
you suspect the sound is not right and you cannot see any markings on the wire to verify polarity is correct, try this
simple test:
1.
Sit in the normal listening position for the system.
2.
Play some music with your receiver set to Mono.
3.
Listen to the music and observe the audio.
A.
Does the bass sound full and even with the other audio?
B.
Do the vocals sound centered and even in volume?
C.
If either of the answers are YES, follow steps 3 and 4 with the other loudspeakers in the system.
4.
Turn off your receiver and reverse the connections for one of the speakers.
5.
Repeat your test at the same volume level. When the sound has the loudest and best sounding bass, and
vocals are centered and clear, your connections are correct and in-phase.
GENERAL MAINTENANCE
INSTALLING AND REMOVING THE GRILLE
• The left and right channel grilles are secured in place with screws from the back side of the speaker. The center
channel grille fits firmly over the assembly using the bent tabs in the back to secure in place. To remove the
grill, pull gently up from the top or bottom of the grille to clear the lip from the speaker. Rotate the grille around
away from the wall until the opposing lip can be cleared from the speaker as well.
• To re-install, center the grille in the desired location and position either the top or bottom bent tab around the
back of the speaker. Gently pull the opposing side of the grill up and around the speaker so that the opposing
tab is secured behind the speaker assembly.
CLEANING
Use a dampened soft cloth or paper towel to clean the cabinet. The grille is best cleaned by brushing it off with a
lint-free cloth.
