BASIC INSTALLATION
CABINETRY CONSIDERATIONS
High bias amplifiers dissipate much of the power they consume in heat.
Because the KSA- 100S/200S/300S utilize Sustained Plateau Biasing, they
remain cool when not in use. When the KSA is in use, it can become quite
hot. Therefore, the KSA should be installed in a location that provides
unobstructed ventilation. If you must install the unit on shelves or in a
cabinet, extra ventilation may be necessary. This often can be accomplished
with cabinet shelf spacing or unit location. In more extreme instances the
use of small fans can aid in removing excessive heat from internal spaces.
Consult your dealer for assistance.
Generally, with the front and rear of a cabinet open, 3-4 inches of clearance
on each side and 8 inches of vertical clearance, the amplifier should have
adequate ventilation.
The KSA amplifiers have very large power supplies. As a consequence the
amplifiers are quite heavy. When purchasing a rack or cabinet, keep weight
in mind. Most racks are not capable of withstanding the weight of these
units.
The exact weight and dimensions for the KSA-100S/200S/300S are in the
Specifications section of this manual.
AC POWER CONSIDERATIONS
The KSA should have a dedicated 20 amp line and should only be operated
with the power cord supplied. Use of other power cords may damage the
amplifier and void its warranty. Please consult KRELL or your dealer
BEFORE using any devices designed to alter or stabilize the AC power for the
KSA. AC line filters and/or stabilizers must meet or exceed the power
transformer size in the amplifier. As an example, the line conditioner will
require a supply reservoir greater than 2800 VA to condition a KSA-200S.
If you have any questions about placement or AC power conditions, please
consult KRELL.
