rack.

4.3 Placement guidelines

For placement of the mixer/amplifier chassis, keep the following in mind:

•Make sure that air can circulate freely behind, beside, and above the chassis for adequate ventilation. There are intake vents on the sides and an exhaust vent on the back of the unit. Do not cover or block the vents.

•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 50° C (122° F). Be aware of conditions in an enclosed rack that may increase the temperature above room- ambient conditions.

4.4 Shelf mounting the chassis

The Bose® FreeSpace® DXA 2120 Digital Mixer/Amplifier has rubber feet for use when positioning the chassis on a shelf or counter top. They help to protect the surface that supports the unit and to prevent chassis movement. Be sure to follow the “Placement guidelines” previously described when choosing a location for the unit.

1.Place the mixer/amplifier upside-down on a solid, level surface on a protective covering to avoid scratching the top of the chassis.

2.Insert the supplied rubber feet to the four existing holes on the bottom of the chassis. Use a screwdriver to push the locking pins fully into the chassis, securing the feet.

Note: The rubber feet may be removed by inserting a screwdriver into the screw and turning counterclockwise until the screw backs out of the hole.

4.5 Rack-mounting the chassis

The chassis requires two 1.75" (4.4 cm) rack-space units with a 16" (40.6 cm) inside depth (including the rear supports).

1.Use the supplied rack ears and hardware for attachment to the chassis.

2.To secure the chassis to the rack, use four screws with washers (not provided) to prevent marring the front panel.

Note: Neoprene rubber washers are a good choice because they grip the screw head and prevent the screws from backing out from vibration or during transportation.

CAUTION: To transport the rack-mounted chassis, be sure the rear of the chassis is supported mechanically in the rack. Install a shelf under the unit or use brackets for rear support. Lack of proper support may result in damage to the chassis.
