Placement
Before you install the Full Power Balanced amplifier into your sys-
tem, please follow the guidelines in this section to choose its proper
location. This will facilitate a clean, trouble-free installation.
The Full Power Balanced amplifier requires at least two inches (5
cm) of clearance on each side and at least eight inches (20 cm)
of clearance above the component to provide adequate ventila-
tion.
Although Sustained Plateau Bias III circuitry reduces the high heat
dissipation and heat output of traditional Class A circuitry, Full
Power Balanced amplifiers still can become hot under normal oper-
ation.
When the front and rear of a cabinet are open the air space
between the chassis and shelf must be unobstructed. If you place
the amplifier in a closed cabinet, you may need to modify shelf
spacing or use small fans to increase ventilation. For the dimen-
sions of your Full Power Balanced amplifier, see
Specifications,
on pages 25–26.
Place the amplifier as close to the loudspeakers as possible. Krell
CAST technology permits you to use interconnect cables of any
length, see
Revolutionary CAST II Technology,
on page 4; how-
ever, try to keep the cable length to a minimum.
All Full Power Balanced amplifiers drive the lowest impedances
with ease. When impedance is added due to long speaker cable
lengths, amplifier power is wasted in the cable. Long speaker
cables reduce the maximum power that is delivered in the speak-
ers.
The Full Power Balanced 300cx and 350Mcx amplifiers need to be
operated from a dedicated AC power line rated at a minimum of 15
amps. The Full Power Balanced 700cx, 750Mcx, 400cx, and
450Mcx amplifiers need to be operated from a dedicated AC power
line rated at a minimum of 20 amps.
Please contact your authorized Krell dealer, distributor, or Krell
before using any devices designed to alter or stabilize the AC
power for Full Power Balanced amplifiers
