4 Krell Full Power Balanced X Series Power Amplifiers
Two people are needed to remove the Full
Power Balanced amplifier from its shipping box
safely and easily.
1. Open the shipping box and remove the top
layer of foam. You see these items:
1 Full Power Balanced Amplifier
1 Packet containing the owner’s
reference manual and the warranty
registration card
2. Orient the shipping box so that one person
stands at the front of the amplifier and one
person stands at the rear of the amplifier.
Both people need to grab a pair of the card-
board handle cutouts (one pair located at the
front of the amplifier and one pair located at
the rear of the amplifier) and simultaneously
lift the amplifier straight up, out of the carton.
3. Place the amplifier in a safe location and
remove the protective plastic wrapping.
Notes
If any of the items mentioned above are not
included in the shipping box, please contact
your authorized Krell dealer, distributor, or Krell
for assistance.
Save all packing materials. If you ship your Full
Power Balanced amplifier in the future, repack
the unit in its original packaging to prevent tran-
sit damage. See Return Authorization Proce-
dure, on page 21 for more information.
Before you install the Full Power Balanced
amplifier into your system, 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 clear-
ance above the component to provide ade-
quate ventilation.
Although Sustained Plateau Bias III circuitry
reduces the high heat dissipation and heat out-
put of traditional Class A circuitry, Full Power
Balanced amplifiers still can become hot under
normal operation.
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 amplifi-
er in a closed cabinet, you may need to modify
shelf spacing or use small fans to increase ven-
tilation. For the dimensions of your Full Power
Balanced amplifier, see Specifications, on
pages 22–23.
Place the amplifier as close to the speakers as
possible. Krell CAST technology permits you to
use interconnect cables of any length, see Rev-
olutionary Krell CAST and CAST II Technol-
ogy on page 3; however, try to keep the cable
length to a minimum.
All Full Power Balanced amplifiers drive the
lowest impedances with ease. When imped-
ance 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 speakers.
