C. BASIC INSTALLATION
AND OPERATION
1. Place the KST-100 on a firm level surface away from
excessive dirt or moisture. Ideally the amplifier should be
placed as close to. the speakers as possible. It is always
preferable to run long_ interconnect cables to the amplifier
and keep speaker calSle length to.a minimum= Speal~er
cable does add an impedance at the output ot the ampli-
fier, regardless of the cable’s g.uage. AIIKRELL amplifiers wilI drive the lowest impeclanc, es with ease. When
impedance is added, the amplifier s power is literally
wasted in driving cable. Long speaker cables reduce the
maximum power that can be delivered to the speakers.
2. Amplifiers dissipate much of the power they consume
in heat. The KST-1~00 should be installed in a location
that provides unobstructed ventilation. If you have t.o
install the unit on shelves or in a cabinet, extra ventilation
may be necessary. This can be accomplished with "whisper"-type fans. Consult your dealer f-or assistance.
Generally, with the front and rear of a cabinet open, 2-3
inches of clearance on each side and 8 inches of clear-
ance above the amplifier should provide adequate ventilation.
The exact dimensions for the KST-100 are in the Specifi-
cations Section below.
3. The KST-100 should have a dedicated line and should
only be operated with the power cord supplied. Use of
other power cords may damage the ampIifier or void its
warranty. Please consult KRELL or your dealer BEFORE
using a~ny devices designed to alter or stabilize the AC
pgwer tor the KST-100. If you have any questions about
placement or AC power conditions please consult
KRELL.
4. The feet on the KST-100 can be used in several differ-
ent ways. They are made from machined Delrin and are
supplied with separate threaded rubber bottoms. The
rubber bottoms can be screwed into the feet tor protec-
tion of fragile surfaces such as hardwood floors or furni-
ture. For use on rugs, we recommend using.the feet wi.th-
out the rubber bottoms. KST-100 feet can also accept tlae
KRELL AMDs (Acoustic Mass Damper). These improve
the amplifier’s sonic performance in most installations.
