Questions and Answers
Q. Should I leave my KCT on at all times?
A. Yes, Krell recommends that you leave your KCT preamplifier in the stand-by mode
when it is not playing music. Turn your system off only if it will not be used for a long
period of time.
Q. When I turn on the KCT there is a loud hum through the loudspeakers. What should
I do?
A. When a new component is introduced into your system, a low frequency hum may
occur in one or both loudspeakers. Check all input and output connections and cables,
making sure they are of sound construction (see Troubleshooting System Noise, on
page 25). If the interconnects and cables are sound, you may be experiencing a ground
loop, which can often be easily eliminated. Please contact your authorized dealer,
distributor, or Krell for suggestions.
Q. Can I use the KCT CAST inputs or outputs with other manufacturers’ components?
A. No. Only CAST-equipped components can be connected to CAST inputs or outputs.
Connecting non-CAST components to these inputs or outputs can damage your
equipment and void your warranty. See Connecting the KCT Preamplifier to your
System, on page 18.
Q. I want my CD player to play through the main zone and the radio to play through
zone 2. Can I play one louder than the other?
A. Yes. Each zone on the KCT has independent volume control, so you can play music
from one input device at the desired volume through the main zone, and play a second
device through zone 2 at a different volume. You can also play an input device through
one zone and record through the other zone, again, at separate volume levels. See
Main Zone and Zone 2 Operation, on page 22. Remember that you’ll need one
amplifier to drive your loudspeakers in the main zone and a second amplifier for the
loudspeakers in zone 2.
Q. When I select the B-1 input on the KCT, one channel seems to have less gain than
the other does. Is something wrong?
A. First, check the balance level using the balance and level keys. (See Remote
Control Description, on page 15.). If balance level is correct, check that the balanced
input or output internal cable terminations are properly connected. Locate the channel
that appears to have less gain. Switch that channel's input cables. If the problem now
appears in the other channel, the cable is defective. If the problem remains in the
original channel, check the output cables using the same procedure.
If the balance settings or cables are not causing the difference in gain, contact your
authorized Krell
dealer, distributor, or Krell.
