If, after connecting your system you find the bass response to be boomy (or
lacking in tightness and solidity) or if the bass driver cones produce excessive
movement, the cause can usually be attributed to acoustic feedback – vibra-
tions from the speakers reaching a turntable and tone arm, creating a reso-
nance. In turn, this vibration is fed back to the electronics and speakers. Since
Omega speakers extend to very low frequencies, isolating the turntable from
vibrations becomes an important procedure. The turntable should be placed
on a heavy, solid support located as far from the speaker as possible. At times,
using a shock-mounted base helps reduce vibration pickup. If, after trying
various methods to reduce acoustic feedback, the phenomenon still exists,
contact your dealer for assistance.
NOTE: CD players, which are susceptible to vibrations, should be mounted on
solid supports to isolate them acoustically. Another method to isolate the CD
player is to mount it on four rubber or plastic legs which have a predeter-
mined amount of elasticity.

Use a soft cloth and a fine furniture oil to clean the wood finish. If you use a
spray cleaner/polish, be careful not to spray the polish on the grille cloth. The
grille may be vacuumed occasionally, but always set the vacuum cleaner on
low suction to avoid tearing the cloth.

Note that you can use your amplifier’s two channels of information for simple
troubleshooting. If the sound quality is distorted, listen to each speaker sepa-
rately to check if the fault is present in both. If it is, then the trouble is likely
to be elsewhere in your system. If the fault is in one channel only, reverse the
outputs from your amplifier to the speakers (right-to-left and left-to-right). If
the distortion moves to the other channel, the fault is not in the speaker. (This
technique may also be used to locate a fault between the signal source and
preamp/receiver and/or between preamp and power amp(s).)
If you have been unsuccessful in locating the specific source of trouble (or if
you have located it, but have been unable to correct it), please consult the
Authorized Infinity Dealer from whom you purchased the system. Infinity
Dealers are audio specialists and can be of great assistance.
