Mounting

The XPA power amplifiers can be set on a table; mounted on a rack shelf; mounted under a desk or other furniture; or mounted in the plenum space above a ceiling-mounted projector.

Tabletop Use

Four self-adhesive rubber feet are included with the audio amplifier.

For tabletop use, attach one foot at each corner of the bottom side of the unit and place the unit in the desired location.

UL Rack Mounting Guidelines

The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of the equipment in a rack.

1.Elevated operating ambient temperature — If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient temperature. Therefore, install the equipment in an environment compatible with the maximum ambient temperature (Tma =

+122 °F/+50 °C) specified by Extron.

2.Reduced air flow — Install the equipment in a rack so that the amount of air flow required for safe operation of the equipment is not compromised.

3.Mechanical loading — Mount the equipment in the rack so that a hazardous condition is not achieved due to uneven mechanical loading.

4.Circuit overloading — Connect the equipment to the supply circuit and consider the effect that circuit overloading might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

5.Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (for example, use of power strips).

Rack Mounting

The XTRA series of audio amplifiers are housed in rack-mountable metal enclosures with pre-attached mounting ears for standard 19-inch racks. Mount the amplifier, as follows:

1.Disconnect all cables and power sources from the amplifier.

2.Position the amplifier in the mounting rack so that the four slots in the mounting ears are aligned with the rack mounting holes. Use the included mounting screws to fasten the amplifier to the rack, as shown in the following diagram.

WARNING: Never place a load exceeding 40 pounds in weight on top of the rack-mounted amplifier.
