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.

2.4 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
