H. OUESTIONS AND ANSWERS
.Q. When I turn up the volume on the KRC-2 a loud hum
is present from ttie loudspeakers. What could it be?
A. Hum can be caused by_ several different disturbances.
Check to make sure all of the cables in and out of the
KRC-2 are sound and making proper contact. Make sure
there are~no power supplies orhum inducing components
on top ot or directly below the KRC-2.
You also could be experiencing a ground loop in the
system. A ground loop can be ca.used whe.n several.
components with diffdrent ground potentials are in the
system. Ground loops can often be easily correcte.d.
Consult your dealer or KRELL for system grounding
considerations.
Q. Can the KRC-2 be used to control more than one
system?
A. Yes, the KRC-2 has both single end.ed and bala.nced
outputs that can be used simultaneously to control two
seperate systems.
Q. When I select the B 1 input on the KRC-2 one channel
seems to have less gain than the other. Is something
wrong with the preamp?
A. More than likely there is not a problem with the
KRC-2. The balanced input or output internal cable
terminations could be incorrect. Switch the suspect cable
to the other channel and vice versa to determine whether
a cable is defective. If the problem switches to the other
channel, it is a defective cable. If the problem does not
move to the other channel and remains the same after
cables have been switched, check the wiring at the input
of the KI~.C,2 with the same process. If it is not cable or
source related call your dealer or KRELL.
Check to make sure there are no LED’s illuminated in the
Balance control section of the front panel. If there are,
correct the balance by pushing the balance contol
switches until no LEDs on the balance control section are
illuminated.
