Amplifiers dissipate much of the power they consume in heat. The
KSA-lOO should be installed in a location that provides unobstructed
ventilation. If you have to install the unit on shelves or in a
cabinet, extra ventilation might be necessary. This can be easily
done with fans in a variety of ways. Generally, with the front and
rear open, 2 - 3 inches clearance each side and 8 inches above the
amplifier, ventilation will be adequate.

The dimensions of the KSA-lOO are: 23" wide x 22" deep x 9 high.
The unit weighs 80 pounds; shipping weight is 100 pounds.

INSTALLATION

After inspection of the amplifier for any shipping damage it is ready
for installation. The wiring to and from the amplifier, and all
components in general, should be arranged in a neat, organized
manner. Specifically, AC wires should be separated from audio wires.
This avoids hum or other unwanted noise from being induced into the

system.

It is always preferable to run long interconnect cables to the
amplifier and keep speaker cable length to a minimum. Speaker cable
does add impedance between the amplifier, regardless of its guage.
All KRELL amplifiers will drive the lowest impedances with ease. When
impedance is added in any significant amount, amplifier power is
literally wasted in driving the cable, thereby reducing the maximum
power that can be delivered to the speaker.

The feet on the KSA-lOO can be used two different ways. They are made
from machined aluminum and are supplied with separate rubber bottoms
and mounting screws. The rubber bottoms can be screwed into the the
feet for protection of fragile surfaces such as hardwood floors or
furniture. For use on rugs We recommend using the feet without the
rubber bottoms.

Once the amplifier is in place and turned off, connect the speaker
and interconnect cables. The preamplifier should be on at this point,
with level fully attenuated; all other sources should be off. Connect
the AC last.

OPERATION

when turning on the system, the amplifier should always be last.
The KSA-lOO on/off switch is actually a circuit breaker that is
involved in several protection circuits. Upon turn-on the amplifiers'
outputs are not connected to the speaker. After the protection
circuits have determined that the unit has completely stabilized, the
speaker relays will be engaged. You will hear a click when at this
point. The amplifier is now ready to use. The amplifier will be at
temperature and sound its best after approximately 15 minutes.
