FEEDBACK

If, after taking care in positioning your speakers, you find the
bass response "boomy" and lacking "tightness", or you hear a rumble
when using your turntable, or you notice exceSSive 'movement of the
woofer cones, the cause may be acoustic feedback. This means that the
vibrations radiating from your woofers are being picked up by your
turntable's cartridge. Because of the extended low frequency response
of the RS IIb, isolating the turntable from these vibrations calls for
considerable care. . .

In general, make sure that the turntable 18 placed on a heavy, solid
support, as far away from the speakers as pOSSible. Some combinations
of turntable, tone arm and cartridge are more apt to encounter
difficulties with feedback than others. If you continue to experience
difficulties after some experimenting, ask your Infinity dealer for
assistance.

HUM

If you should experience an audible 50/60 cycle bum in your
speakers, first check all cables and connections (especially your
turntable's ground wire), and exchange the cables, one at a time, with
ones that you are certain are functioning properly. If all of the
cables and connections are proven to be okay, invert the two-prong
A.C. plugs in their recepticles. If this does not solve the problem,
you may try using a two-prong adapter (commonly called a cheater or a
floater) on the A.C. power cords of your components that have three-
prong plugs, one at a time, until the hum is eliminated. If floating
is necessary, always keep AT LEAST ONE component grounded.

If the hum persists, and if none of the above suggestions seem to
help, consult your Infinity dealer.
