2 Setup

2.1 Unpack Your Amplifier

Please unpack and inspect your amplifier 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 Rack for mounting amplifier (or a stable surface

for stacking)

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

2.2 Install Your Amplifier

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 (counterclockwise).

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

You may also stack amps without using a cabinet.

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

2.3 Ensure Proper Cooling

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, rear or side air vents. The side walls of the rack should be a minimum of two inches (5.1 cm) away from the amplifier sides, and the back of the rack should be a minimum of four inches (10.2 cm) from the amplifier back panel.

2 Setup

2.4 Choose Input Wire and Connectors

Crown recommends using pre-built or professionally wired balanced line (two-conductor plus shield), 22-24 gauge cables and connectors. At the amplifier inputs, use either:

• 3-pin male XLR cable ends,

• TRS or TS 1/4" phone plugs, or

• Phoenix-style connectors.

Unbalanced lines may be used, but may result in noise over long cable runs.

Figure 2.3 shows XLR wiring, Figure 2.4 shows 1/4" phone plug wiring, and Figure 2.5 shows Phoenix-style connector wiring.

NOTE: Custom wiring should only be performed by qualified personnel.

and Unbalanced (Bottom)

2.5 Choose Output Wire and Connectors

Crown recommends using pre-built or professionally wired, highquality, two- or four-conductor, heavy gauge speaker wire and connectors. You can use banana plugs, spade lugs, or bare wire for your output connectors (Figure 2.6). Also, you can use a 4pole Speakon

connector (Figure 2.7 and Table 1). To prevent the possibility of short-circuits, wrap or otherwise insulate exposed loudspeaker cable connectors.

Note: Binding post outputs on European models come with safety plugs installed to prevent European powercord plugs from being inserted. The top & bottom entry positions for these connectors should therefore be used with European models.

Using the guidelines below, select the appropriate size of wire based on the distance from amplifier to speaker.

Distance Wire Size

up to 25 ft. 16 AWG 26-40 ft. 14 AWG 41-60 ft. 12 AWG 61-100 ft. 10 AWG 101-150 ft. 8 AWG 151-250 ft. 6 AWG

CAUTION: Never use shielded cable for output wiring.

2.6.2 How to Parallel the Inputs

There are three ways to feed the same signal to each amplifier channel:

1. Buy a “Y” cable. Plug the female end into your signal cable, and plug the split male ends into both amplifier inputs.

2. Feed your signal to the Channel-1 input (either Phoenix or combo). Connect a jumper wire (Figure 2.9) between the Phoenix Channel-1 (+) screw terminal and the Channel-2 (+) screw terminal. Connect another jumper wire between the Channel-1 (–) screw terminal and the Channel-2 (–) screw terminal.

3. Feed your signal to the Channel-1 Phoenix terminals. Using a mic cable or phone-to-phone cable, connect Channel-1 combo jack to Channel-2 combo jack.
