Model PA250-001 250 Watt Central Amplifier

Installation

WARNING

Please follow below recommendations and instructions for installation.

CAUTION

These installation instructions are for use by qualified service personnel only.

To reduce the risk of electric shock, DO NOT perform any servicing other than contained in the

operating instructions unless you are qualified to do so.

1. Ensure the installation conforms to all applicable local electrical codes.

2. Use only properly grounded ac receptacle for ac power connection to reduce the risk of shock hazards

as well as lessen possible noise to the unit.

3. Avoid running input and output signal cabling near high voltage/high electromagnetic sources.

4. All speaker output connections are CLASS 2 wiring.

DANGER

DO NOT install in hazardous areas.

5. Use in safe, non-classified, non-hazardous areas only.

6. The total power distribution to the speakers MUST NOT exceed the amplifier's rated output wattage.

Rack Mount Installation

The power amplifier can be mounted into a standard 19-inch equipment rack, if desired. Place the

amplifier in the desired rack location and secure with proper rack mounting hardware (customer-

supplied). For best protection to the amplifier's mounting hole finish, the use of nylon or plastic washers

is recommended.

Note: To meet the two-rack space (2U) spacing, the amplifier's rubber feet must be removed. To remove

them, flip the unit upside down and remove the Phillips screw located in the center of each foot.

Ventilation

The amplifier creates heat during operation. Although the amount of heat generated varies, the unit

should be positioned to allow for natural convection airflow to prevent excessive temperature rise. DO

NOT block the amplifier's heatsink fins or holes located in the covers.

If additional amplifiers or other heat producing equipment is installed within the equipment rack, ensure

that the ambient temperature near the amplifiers does not exceed ~50 °C during normal operation by

installing adequate rack ventilation fans.

Note: If, during normal operation, the ambient temperature exceeds ~50 °C inside the equipment rack,

increase the spacing distance between the amplifiers and adjacent equipment. Also, install suitable

equipment rack fans to reduce cabinet's ambient temperature to below ~50 °C.

The amplifier has three audio-in connections mounted on the amplifier rear panel designed for wide

acceptance without the need for additional accessories. Refer to Figure 4.
