OPERATION
SYSTEM NOISE CONSIDERATIONS
AC grounding often becomes critical when connecting high performance audio gear. When mixing and matching audio components, each with their
own ground potentials, a low frequency hum can become present in one or both speakers. This can often occur when introducing a new component into the system.
If there is a low frequency hum coming from the speakers when the KSAis
connected into the system, follow these simple
1.Check all of the input and output connections, making sure they are of
sound construction. With the amplifier off, remove the interconnect wiring
and tum the amplifier back on. If the hum disappears, shut the amplifier off and reinsert one of the interconnect cables and turn the amplifier back on. If the hum is present with one or both interconnects inserted, there may be a defective cable. Have the interconnect cabling checked before proceed- ing.
2.If the interconnect proves to be fine, more than likely you are experiencing a ground loop. This can often easily be eliminated. Contact your dealer or KRELLfor assistance.
