by pressing the silver power button. It is now safe to turn off the rest of the
system.
NOTE: For optimal performance, the rear panel power breaker should be left in
the ON position at all times.
Remote Control Operation
An optional remote control is available for the Full Power Balanced amplifiers.
The amplifiers can be switched between Standby and Operate via this remote
control or from the remote controls included with KRELL preamplifiers, the
KRELL Audio + Video Standard, and the KPS 25s KRELL Playback System.
System Noise C0hsiderati0ns
AC grounding Eecomes critical when connecting high performance audio
components. When mixing and ma.tching audio components, each with their
own ground potential, a low frequency hum may occur in one or both speakers.
This often occurs when introducing a new component into a system.
If there is a low frequency hum emanating from the speakers when the Full
Power Balanced amplifier is placed into the system, follow these simple trouble-
shooting steps before cont~lcting your KRELL dealer: "
Check a!! input and output connections, making sure they are of sound
construction. With the amplifier off. remove the interconnect wiring and turn
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 reappears with one or both interconnects reinserted, there may be a
defective cable. Have the interconnect cabling checked before proceeding.
If the interconnects prove to be sound, you may be experiencing a ground
loop. This can often be easily eliminated. Contact your dealer or KRELL for
assistance.
Protection Circuitry
There are no output fuses in the Full Power Balanced amplifiers. The amplifiers
are protected by a series of non-intrusive circuits that constantly evaluate the
amplifier’s operation. Appropriate protection action exists for input and output
DC conditions, short circuit, regulator uniformity, and AC power anomalies.
Collectively, the protection circuitry is designed to avoid damage to the amplifier
or speakers caused by other defective components, faulty wiring, system
