Cabinetry Considerations

BASIC INSTALLATION

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 KSAis in use, it can become quite

hot. Therefore, the KSAshould 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. Whenpurchasing 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 KRELLor your dealer BEFOREusing any devices designed to alter or stabilize the ACpower 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 VAto condition a KSA-200S.

If you have any questions about placement or AC power conditions, please consult KRELL.
