IMPORTANT
CE Series amplifiers require Class 2 output wiring.
MAGNETIC FIELD
CAUTION! Do not locate sensitive high-gain equipment such as preamplifiers or tape decks 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.
WATCH FOR THESE SYMBOLS:
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.

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 and rack-mounting hardware for mount-
ing 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 power switch in the
“off” position and all level controls
turned completely down (counterclockwise).
Use a standard 19-inch (48.3 cm) equipment
rack. 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 or rear air vents. The side walls of
the rack should be a minimum of 2 inches (5.1
cm) away from the amplifier sides, and the back
of the rack should be a minimum of 4 inches
(10.2 cm) from the amplifier back panel.

2.4 Choose Input Wire and Connectors
You have three choices of input connectors:
1/4-inch (6.35-mm) phone, 3-pin XLR, or
barrier strip. You can also use either balanced or
unbalanced wiring.
Figure 2.3 shows balanced connector pin
assignments for XLR and phone. Figure 2.4
shows unbalanced connector pin assignments
for XLR and phone.
Figure 2.5 shows barrier strip input wiring for a
balanced signal. Both channels should be wired
using a common center terminal for ground connection.
NOTE: Custom wiring should only be
performed by qualified personnel.

2 Setup
2.5 Choose Output Wire and Connectors
Crown recommends using pre-built or professionally wired, high-quality, two- or four-conductor, heavy gauge speaker wires. They should
be terminated with Neutrik Speakon NL4FC connectors (Figure 2.6) at one end and appropriate
connectors to fit your speakers at the other end.
If your CE Series amplifier came equipped with
the CEAS1 (barrier strip) or CEAS2 (5-way binding post) optional output connectors, you may
wire your output to these connectors instead.
Optional output connectors can also be ordered
as a Service Option for installation on existing
CE Series amplifiers.
If the CEAS1 Output Module is installed, use terminal forks or bare wire for your output connectors (see Figure 2.7).
To prevent the possibility of short-circuits, replace the cover on the barrier
strip after completing the output wiring.
If the CEAS2 Output Module is installed, connect
to it with bare wires, spade lugs or banana plugs
on the speaker cables (Figure 2.8).
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 gauge
26-40 ft. 14 gauge 41-60 ft. 12 gauge
61-100 ft. 10 gauge 101-150 ft. 8 gauge 151-250 ft. 6 gauge
