4. Installation and Placement
4.1 Importance of proper ventilation
For placement of the amplifier, keep the following in mind:
• Make sure that air can circulate freely around the amplifier for adequate ventilation. There are vents on the top, bottom,
and sides.
• Do not cover or block amplifier vents.
• Do not enclose amplifier in a small space, such as a cabinet.
• Make sure the chassis is protected from heat and kept away from direct heat sources, such as heating vents and
radiators.
Caution: Do not allow the chassis to exceed the maximum operating temperature of 40° C (122° F). Be aware of
conditions in an enclosed rack that may increase the temperature above room-ambient conditions.
Note: If the amplifier becomes too hot, it will go into a thermal protection mode and mute all outputs.
4.2 Placing on a flat surface
The amplifier can be placed on a flat, stable surface like a table, counter, or shelf. Plastic feet are included with the
amplifier to protect the surface area, prevent the chassis from sliding, and allow heat to escape from the bottom vent.
Note: The included feet should always be used when placing amplifier on a flat surface to ensure proper ventilation.
4.2.1 Installing the feet on the amplifier
The included feet are comprised of two parts: a foot and a pin.
1. Place the amplifier upside-down on a flat, level surface on a protective covering to avoid scratching the top of the
chassis.
2. Insert the four feet into the four holes on the bottom of the chassis.
3. Insert a pin into the hole on the foot.
4. Press down on the pin until the foot locks into place. Repeat for all four feet.
4.2.2 Stacking units
One amplifier can be stacked on top of another when there is limited space available on a table, counter, or shelf.
Note: The included feet always should be used on both amplifiers when stacking them to ensure proper ventilation.
