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.

CE Series Power Amplifiers
1 Welcome
CE Series amplifiers provide professional audio amplification for a wide range of applications, including digital cinema. The amplifiers are very affordable, and feature front-panel controls for easy setup and use. They can be removed for security.
Modern power amplifiers are sophisticated pieces of engineering capable of producing extremely high power levels. They must be treated with respect and correctly installed if they are to provide the many years of reliable service for which they were designed.
In addition, CE Series amplifiers include a number of features which require some explanation before they can be used to their maximum advantage.
Please take the time to study this manual so that you can obtain the best possible service from your amplifier.
1.1 Features
•Accurate, undistorted sound.
•Bridge-mono/stereo mode switch allows you to set up your amps/speakers in the configuration that best suits your needs.
•Versatile; handles a wide range of speaker impedances and outputs.
•Advanced protection circuitry guards against shorted outputs, open circuits, DC, mismatched loads, general overheating, high-frequency overloads and internal faults.
•Genuine Neutrik® Speakon® connectors.
•Choice of 1/4-inch, XLR or barrier strip inputs.
•Removable front-panel level control knobs.
•Selectable input sensitivity
•Proportional-speed fan optimizes cooling efficiency.
•Can be mounted in EIA standard 19-in. (48.3-cm) rack, shallow 14-in. (35.5) rack, or stacked on top of each other.
•Three Year, No-Fault, Fully-Transferable Warranty completely protects your investment and guarantees its specifications.
•Crown’s advance-replacement Profit Protection Plan provides quick, no-questions- asked replacement of covered amps.
1.2 How to Use This Manual
This manual provides you with the necessary information to safely and correctly setup and operate your amplifier. It does not cover every aspect of installation, setup or operation that might occur under every condition. For additional information, please consult Crown’s
Amplifier Application Guide (available online at www.crownaudio.com), Crown Technical Support, your system installer or retailer.
We strongly recommend you read all instructions, warnings 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.

2.1 Unpack Your Amplifier |
2.2 Install 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 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.
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.
Figure 2.1 CE 1000 and CE 2000 Dimensions
Operation Manual
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.
Figure 2.2 illustrates standard amplifier airflow.

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, twoor four-con- ductor, 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-cir- cuits, 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 |
CAUTION: Never use shielded cable for output wiring.

2 Setup
2.6 Wire Your System
2.6.1 Stereo Mode
Make sure the amplifier is turned off and the level controls are turned down before you wire the system.
Typical input and output wiring is shown in
Figure 2.9.
INPUTS: Connect input wiring for each channel.
OUTPUTS: Maintain proper polarity (+/–) on output connectors.
Connect Channel 1 positive (+) speaker load to Channel 1 positive terminal of amp; repeat for negative (–). Repeat each channel wiring as for Channel 1. Refer to Section 3.5 for output connector pin assignments. Make sure the Mode switch is set to the “Stereo” position when operating in Stereo mode.
See the next page for Bridge-Mono wiring.

2 Setup
2.6.2 Bridge-Mono Mode
Make sure the amplifier is turned off and the level controls are turned down before you wire the system.
Typical input and output wiring is shown in
Figure 2.10.
INPUTS: Connect input wiring to CH 1.
OUTPUTS: Connect the speaker across the positive (+) output terminals. Do not use the negative
(–) terminals when the amplifier is being operated in Bridge-Mono mode. Refer to Section 2.5 for output connector pin assignments. Make sure the Mode switch is set to the “Bridge” position when operating in Bridge-Mono mode.
NOTE: Turn down (full CCW) the Channel 2 level control when operating the channel pair in Bridge-Mono mode, as the Channel 1 level control works both channels.
NOTE: Crown provides a reference of wiring pin assignments for commonly used connector types in the Crown Amplifier Application Guide available at www.crownaudio.com.
