SYSTEM
The volume control settings on your stereo preamplifier, receiver or integrated
amplifier is not an indication of the overall volume level of your system. The only
important consideration is the loudness level at which the system can be played
regardless of where the volume control is set.
Always turn down the volume when changing a record or switching inputs from
AM to FM, phono or CD operation. Excessively loud transients (loud pops and clicks)
can damage your speakers. Whenever changing plugs, cables, etc., always turn off
your system. This will prevent transients form reaching your speakers and also
prevents electrical energy from reaching you. Keep electrical connections out of reach
of children.
Acoustic feedback is created when sound waves from speakers reach a phono turntable
and are fed back through the phono pickup to the power amplifier. It is a never ending
cycle which can cause distortion across the entire audio band. To avoid acoustic
feedback problems, place your turntable on a heavy, solid support and as far away
from the speakers as possible. At times, isolating the turntable with special rubber
mounts may aid in reducing this form of distortion.
An amplifier with limited power output can actually cause damage to your speakers.
A lower powered amplifier, when played beyond it power capability, will clip. This
generates spurious high frequency signals which, when routed to the tweeter, can cause
it to overheat and fail. It is for this reason that choosing an amplifier with higher power
is always a wise choice.

Note that you can use your amplifier’s two channels of information for simple trouble-
shooting. If the sound quality is distorted, listen to each speaker separately 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), make inquiries
in the following order:
Consult the Authorized Infinity Dealer from whom you purchased the system.
