Q. Why do I have to turn up the volume so high to get music at a normal
listening level?
Ao
If your system does not seem to have enough gain, you are probably not
using the balanced input and output capabilities of the KRC-HR. Each
balanced termination has 6dB more gain than a single-ended termination.
More important, however, is that the balanced lines provide superior sonic
quality. If you must use single-ended terminations, use the High gain
setting, which has 6dB more gain than the Low position.
Q. The pilot LED in the KRC-HR and its power supply are not illuminated.
What should I do?
Check the fuse in the back of the power supply. If there is a break in the
wire inside the fuse, replace it. If there is no break in the fuse, call your
dealer or KRELL. If, when you replace the fuse, the unit powers up and
shuts off shortly thereafter, call the factory.
Q. When I push the function buttons on the KRC-HR remote control, the
preamp does not respond. What should I do?
A. Check the batteries and change them, if necessary.
Q. The selected input button on the KRC-HR is blinking on and off. I cannot
stop the blinking, nor can I play music, what is wrong?
A0
That selected input has developed a problem, causing the KRC-HR to
disable that input. After correcting the problem, the unit will return to
normal. Refer to the section on Protection Circuitry (Page 1 1), for a more
detailed explanation.
