Question And Answer - Krell Industries 600 Instructions For Use Manual

Question and Answer
Q. Should I leave the Full Power Balanced amplifier on at all times?
For maximum performance, the rear panel breaker should remain on at all
times. This is the stand-by position. From this position, the Full Power
Balanced amplifier is designed to be turned On/Off without the "cold start"
degradations associated with other products. The amplifier will operate at
full performance within minutes of turn-on.
Q. When I turn the amplifier on there is a loud hum through the speakers. What
should I do?
Ao
When a new Component is introduced, a hum may be~:ome present. This is
often caused by a ground loop or defective cabling. Check your cables to
and from the amplifier. See the Noise Considerations section for more
information, if the hum persists., contact your dealer or the KRELL staff for
assistance.
Q. My system includes multiple pairs of speakers~ Can ! connect them to the
Full Power Balanced amplifier through a speaker selector box?
No. Most speaker selector boxes utilize a commoh ground. The differential
circuitry in the Full Power Balanced amplifiers prohibits the use of these
devices. Do not connect a Full Power Balanced amplifier to a speaker
selector device that employs a common ground scheme.
Q. My speakers only have one set of binding posts. Which set of speaker
terminals should I use on the amplifier?
A. The two sets of speaker terminals for each channel on the Full Power
Balanced are identical. You can use either the top or bottom set. They
sound and work the same.
Q. My speakers are rated for 150 watts, is the Full Power Balar~ced 300 or Full
Power Balanced 600 too powerful for them.
Seldom is a speaker damaged from over-driving. More often, damage occurs
when an amplifier that lacks sufficient power is asked to handle heavy
demand situations. These amplifiers may have very high 8.Q power ratings,
but in heavy demand situations they can be driven into clipping that damages
speakers. Because of their tremendous capabilities, the Full Power
Balanced amplifiers are capable of damaging speakers, but a responsible
listener should know the limitations of his/her system and exercise caution.
