I-Tech HD Series Power Amplifiers

2 Setup

2.1 Unpack and Install Your

Amplifier

Please unpack and inspect your amplifi er for any damage that may have occurred during transit. If damage is found, notify the transportation company immediately. Only you can initiate a claim for shipping damage. Crown will be happy to help as needed. Save the shipping carton as evidence of damage for the shipper’s inspection.

We also recommend that you save all packing materials so you will have them if you ever need to transport the unit. Never ship the unit without the factory pack.

YOU WILL NEED (not supplied):

• Input wiring cables

• Output wiring cables

• Ethernet cables

• Rack for mounting amplifi er (or a stable surface for stacking)

WARNING: Before you start to set up your amplifier, make sure you read and observe the Important Safety Instruc- tions found at the beginning of this manual.

CAUTION: Before you begin, make sure your amplifier is disconnected from the power source, with the power switch in the “off” position and all level controls turned completely down (counterclock- wise).

Use a standard 19-inch (48.3 cm) equipment rack (EIA RS-310B). See Figure 2.1 for amplifi er dimensions.

You may also stack amps without using a cabinet.

NOTE: When transporting, amplifi ers should be supported at both front and back.

MAGNETIC FIELD

CAUTION! Do not locate sensitive high-gain equipment such as preamplifi ers or tape decks directly above or below the unit. Because this amplifi er has a high power density, it has a strong magnetic fi eld which can induce hum into unshielded devices that are located nearby. The fi eld is strongest on the right side and right bottom of the amplifi er (facing the amplifi er).

If an equipment rack is used, we recommend locating sensitive equipment at least 20 cm (8 inches) away from the amplifi er.

When using an equipment rack, mount units directly on top of each other. Close any open spaces in rack with blank panels. DO NOT block front or rear air vents. The side walls of the rack should be a minimum of two inches (5.1 cm) away from the amplifi er sides, and the back of the rack should be a minimum of four inches (10.2 cm) from the amplifi er back panel.
