When a cart is used, use caution when moving the cart/
apparatus combination to avoid injury from tip-over.
13. Unplug this apparatus during lightning storms or when
unused for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing
is required when the apparatus has been damaged in
any way, such as power-supply cord or plug is damaged,
liquid has been spilled or objects have fallen into the
apparatus, the apparatus has been exposed to rain
or moisture, does not operate nor mally, or has been
dropped.
15. Use the mains plug to disconnect the apparatus from the

EQUIPMENT.
18. THE MAINS PLUG OF THE POWER SUPPLY CORD SHALL
REMAIN READILY OPERABLE.
Important Safety Instructions
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.
The lightning bolt triangle is used to alert the user to the risk of
electric shock.
The exclamation point triangle is used to alert the user to
important operating or maintenance instructions.
REGARDEZ CES SYMBOLES:
La triangle avec le sigle ‘’foudre’’ est employée pour alerter
l’utilisateur au risque de décharge électrique. Le triangle avec

additional information, please consult Crown’s Amplifier
Application Guide (available online at www.crownau dio.
com), Crown Technical Support, your system installer or
retailer.
We strongly recommend you read all instructions,
warn ings and cautions contained in this manual. Also,
for your protection, please send in your warranty
registration card today. And save your bill of sale — it’s
your official proof of purchase.

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 amplifier (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 Instruc tions
found at the beginning of this
manual.
Figure 2.2
Airflow
Figure 2.1
Dimensions
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 (counterclock-
wise).
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.

2.4 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
