QUESTIONS AND ANSWERS

Q. While listening to my REFERENCE64 1 experience occasional periods of silence through my speakers. Is my Processor malfunc- tioning?

A. Drop outs are caused by two primary reasons. First, drop outs

can be caused by data corruption. Corruption in the data may be due to a poor input connection, damaged or dirty source material,

or interconnects which do not have enough bandwidth. The second item that causes the Processor to reset is the presence of

a transient spike on the incoming AC power line. The Processor is resetting all of its digital processing circuits so that it can be

assured all are properly synchronized. Try changing your source

material and check your connections. If these are not the cause,

speak with your dealer about obtaining different cabling. If you are using fiber optics, and source material and connections are not the problem, speak with your authorized dealer.

Q. Since I installed the Processor in my system I have a low level

hum that increases as I turn up the volume. There was no hum

in my system until I added the Processor. Is the Processor malfunctioning?

A. The fact that there was no hum in your system until you added

the Processor indicates that you have a ground-loop problem.

Often changing the interconnect to a fiber optic cable will eliminate this problem. The way the digital Processor and digital source are connected to the AC mains often can be the cause of

grounding problems. Check for loose interconnect cables

and/or bad electrical connections. Consult your dealer or Krell

for individual system suggestions if this hum persists.
