Location
Place the Full Powe~ Balanced amplifier on a firm level surface away from dirt or
moisture. When using custom racks or cabinetry, keep in mind the weight and
ventilation requirements for these amplifiers. Ideally, the amplifier should be
placed as close to the speakers as possible. It is preferable to run long
balanced interconnect cables to the amplifier and keep the speaker cable
length to a minimum. Speaker cable adds impedance to the I-6ad the amplifier
must drive, regardless of the cable's gauge. All KRELL amplifiers will drive the
lowest impedances with ease, but when impedance is added due to long cable
lengths, amplifier power is wasted in the cable. Long speaker cables reduce the
maximum power that can be delivered to the speakers.
Remote Installation
Some installations do not have adequate, space or flexibility to place the amplifier
close to the speakers. The Full Power Balanced amplifiers can be situated in a
room or space close to the speakers, but out of sight, .and turned On or Off from
the listening room. Intemally, a provision has been made allowing the amplifier
to be powered On from an AC wall receptacle and not from the front panel power
switch or optional remote control. We suggest mounting a standard wall switch
in the listening room that controls an AC power outlet dedicated to the power
amplifier. This arrangement can be provided by an electrician. Please contact
your dealer for assistance.
NOTE: Once AC power is applied, the front panel power switch and the remote

Cabinetry Considerations
Class A operation offers tremendous sonic benefits. Unfortunately, traditional
Class A amplifiers dissipate a tremendous amount of heat. KRELL's patented
Sustained Plateau Bias circuitry combats this characteristic and reduces the heat
output considerably. However, the Full Power Balanced amplifiers can still
become quite warm under normal operation. The Full Power Balanced amplifiers
should be installed in a location that provides unobstructed ventilation.
IMPORTANT: The ventilation gdds on the top of all Full Power Balanced
amplifiers need to be unobstructed at all times during operation. Do not place
flammable material on top of or beneath Full Power Balanced amplifiers. For
installations inside cabinetry, extra ventilation may be necessary. Make sure the
Full Power Balanced amplifiers have adequate air circulation. Generally, two
inches of clearance on each side of the amplifier and eight inches of clearance
above the amplifier will provide adequate ventilation. In more extreme instances,
-, small fans can aid in removing excess heat from internal spaces-. Contact your
dealer, distributor, or Kreil®for more information.
