CE 4000 Power Amplifier 1 Welcome ® Crown CE 4000 amplifiers have been engineered from the bottom up to provide superior power output, increased efficiency, legendary Crown sound and extraordinary reliability. They were designed using Crown’s patented, award-wining BCA® (Balanced Current Amplifier) engineering. • Sub-bass output via integral 4-position high-pass and 3-position low-pass filter sets for each channel.
CE 4000 Power Amplifier 3 Setup 3.1 Unpack Your Amplifier 3.2 Install Your Amplifier 3.3 Ensure Proper Cooling YOU WILL NEED (not supplied): 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). 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.
CE 4000 Power Amplifier 3 Setup 3.4 Choose Input Wire and Connectors Balanced Line Unbalanced Line Crown recommends using pre-built or professionally wired, balanced line (two-conductor plus shield), 22-24 gauge cables and connectors. Depending upon which amplifier input you choose, you should use either 3-pin male XLR connectors, TRS phone connectors, or terminal forks at the amplifier inputs. Unbalanced line may also be used but may result in noise over long cable runs.
CE 4000 Power Amplifier 3 Setup 3.5 Choose Output Wire and Connectors Crown recommends using pre-built or professionally wired, high-quality, two- or fourconductor, heavy gauge speaker wire and connectors. If your amplifier includes Neutrik® Speakon® outputs, use male Speakon NL4C connectors for your output connectors (see Figure 3.5). If your amplifier includes barrier block outputs, you may use spade lugs or bare wire for your output connectors (see Figure 3.6).
CE 4000 Power Amplifier 3 Setup 3.6 Wire Your System 3.6.1 Stereo Mode Typical input and output wiring is shown in Figure 3.8. INPUTS: Connect input wiring for both channels. OUTPUTS: Maintain proper polarity (+/-) on output connectors. Connect Channel-1 positive (+) speaker load to Channel-1 positive terminal of amp; repeat for negative (-). Repeat Channel-2 wiring as for Channel 1. Refer to Section 3.6 for output connector pin assignments.
CE 4000 Power Amplifier 3 Setup 4 Operation 3.7 Connect to AC Mains Connect your amplifier to the AC mains power source (power outlet) with the supplied AC power cordset. First, connect the IEC end of the cordset to the IEC connector on the amplifier; then, plug the other end of the cordset to the AC mains. 4.1 Precautions Your amplifier is protected from internal and external faults, but you should still take the following precautions for optimum performance and safety: 1.

Mode Switch Allows selection of Stereo or Bridge operation. L. IEC Power Connector P. Low-Pass Filter Switch Allows selection of Flat, 80 Hz or 100 Hz roll-off.
CE 4000 Power Amplifier 5 Advanced Features and Options 4. NOTE: For detailed information about these Crown amplifier features, please consult the Crown Amplifier Application Guide, available on the Crown website at www.crownaudio.com. 5.1 Protection Systems Your Crown amplifier provides extensive protection and diagnostic capabilities, including built-in anti-clip limiters, amplifier fault protection, and switchable high-pass filters. Figure 5.2 Fault Jack 5.1.
CE 4000 Power Amplifier PFC, however, compensates for phase differences in the power supply, allowing more true power to be transferred to the amplifier. The result is more power with less waste than any other conventional switching or non-switching design. 5.3.2 Neutrik Speakon Wiring The Neutrik Speakon NL4 connector is a fourpole type, which allows either one or two sets of speakers to be wired to one connector. Figure 5.5 shows the wiring pin assignments. 5.4.
CE 4000 Power Amplifier 6 Troubleshooting CONDITION: Normal operation. CONDITION: No sound. POSSIBLE REASON: POSSIBLE REASON: • This is normal operation for your amp. • The amplifier has just been turned on and is still in the 4-second turn-on delay. CONDITION: No power to the amplifier. POSSIBLE REASON: • The amplifier’s “Power” switch is off. • The amplifier is not plugged into the power receptacle. • The amplifier’s high-voltage power supply fuse has blown.
