MAGNETIC FIELD

CAUTION! Do not locate sensitive high-gain equipment such as pre­amplifiers directly above or below the unit. Because this amplifier has a
high power density, it has a strong magnetic field which can induce hum
into unshielded devices that are located nearby. The field is strongest
just above and below the unit.

If an equipment rack is used, we recommend locating the amplifier(s)
in the bottom of the rack and the preamplifier or other sensitive equip­ment at the top.

FCC COMPLIANCE NOTICE

This device complies with part 15 of the FCC rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired
operation.

CAUTION: Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.

NOTE: This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This equip­ment generates, uses, and can radiate radio frequency energy and, if not installed and used
in accordance with the instruction manual, may cause harmful interference to radio com­munications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television recep­tion, which can be determined by turning the equipment off and on, the user is encouraged
to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to which the

receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

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
transpor tation company immediately. Only you
can ini tiate 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 amplier (or a stable

sur face 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 ampli fier
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 or rear air vents. The back of the rack
should be open.

Figure 2.2 illustrates standard amplifier airflow.

2 Setup (continued)

Figure 2.3 Input Connector Phoenix Wiring,
Bal anced (Top) and Unbalanced (Bottom)

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
Phoe nix-style connectors (see Figure 2.3).

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

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

2.5 Choose Output Wire and Connectors

Crown recommends using pre-built or professionally
wired, high-quality, two-conductor, heavy gauge
speaker wire and connectors. You can use spade lugs or
bare wire for your output connectors (Figure 2.4). To
prevent the possibility of short-circuits, wrap or
other wise insulate exposed loudspeaker cable
connectors.

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.
