CE2000TX Power Amplifier 1 Welcome Crown® CE 2000TX amplifiers provide professional audio amplification for a wide range of applications, such as digital cinema. The amplifier is very affordable, and features frontpanel 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.
CE2000TX Power Amplifier 3 Setup 3.1 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.
CE2000TX Power Amplifier 3 Setup 3.4 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 3.3 shows balanced connector pin assignments for XLR and phone. Figure 3.4 shows unbalanced connector pin assignments for XLR and phone. Figure 3.5 shows barrier strip input wiring for a balanced signal.
CE2000TX Power Amplifier 3 Setup 3.5 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 3.6) at one end and appropriate connectors to fit your speakers at the other end.
CE2000TX Power Amplifier 3 Setup 3.6 Wire Your System 3.6.1 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 3.9. INPUTS: Connect input wiring for each channel. OUTPUTS: Maintain proper polarity (+/-) on output connectors. SHOWN WITH OPTIONAL CEAS1 OUTPUT MODULE Connect Channel 1 positive (+) speaker load to Channel 1 positive terminal of amp; repeat for negative (-).
CE2000TX Power Amplifier 3 Setup 3.6.2 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 3.11. INPUTS: Connect input wiring to lower-numbered channel pair. OUTPUTS: Connect the speaker across the positive terminals of each channel pair. Do not use the negative terminals of the channel pair when the pair is being operated in Bridge-Mono mode. Refer to Section 3.

CE2000TX Power Amplifier 3 Setup 3.7 Input Sensitivity Switch A two-position Input Sensitivity switch is located on the back panel near the input connectors (Figure 3.15). Your amplifier is shipped from the factory with this switch set to the 1.4V position. At this setting, a 1.4V input signal will drive the amplifier to full power into an 8 ohm load when the level controls are turned to maximum.

CE2000TX Power Amplifier 5 Advanced Features and Options 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 CE 2000TX amplifiers are protected against shorted, open or mismatched loads; overloaded power supplies; excessive temperature; chain destruction phenomena; input overload damage; and high-frequency blowups.
CE2000TX Power Amplifier 5 Advanced Features and Options SST-SBSC-3632T SST-4622 This is a custom three-channel crossover network with CD-horn equalization and summed low-frequency output specifically designed for use with JBL® model 3632T ScreenArray® cinema speaker systems installed in cinemas, studio production and post-production environments. See Figure 5.1.
CE2000TX Power Amplifier 5 Advanced Features and Options 5.2.2 Fault Monitoring The Fault (RJ-11) jack, which looks like a telephone plug, is located on the back of your CE 2000TX amplifier (Figure 5.2). It gives you an easy way to remotely monitor the amplifier’s fault status. To set up a circuit that will cause an LED to light whenever a fault status occurs, you can simply use the suggested circuit shown in Figure 5.3.
CE2000TX Power Amplifier 5 Advanced Features and Options 5.3 Options 5.3.1 Alternate Output Connectors For added system flexibility, Crown offers optional secondary output connectors, with a choice of either model CEAS1 barrier block (see Figure 5.5) or model CEAS2 5-way binding post connectors (see Figure 5.6). Alternate output connectors may come factory installed on new amplifier orders. They can also be added to existing CE 2000TX amplifiers by an authorized Crown Service Center.
CE2000TX Power Amplifier 6 Principles of Operation For the sake of simplicity, only channel one of the amplifier is described. Signal is presented to the CE 2000TX through one of three connectors when using the standard input module. Each channel is outfitted with a balanced XLR / phone jack and a barrier strip. These connectors are wired in parallel, which allows daisy chaining when needed.

CE2000TX Power Amplifier 7 Troubleshooting CONDITION: Power indicator is off. POSSIBLE REASON CONDITION: Distorted sound. POSSIBLE REASON: • The amplifier has lost AC power. • • The amplifier’s Power switch is off. Load is wired incorrectly or Stereo/Mono mode switch is set incorrectly. Check both. • The amplifier’s power cord is not plugged in at either end. • Input signal level is too high. Turn down your amplifier level controls, or turn down the input signal, until the clip LED goes out.

CE2000TX Power Amplifier 9 Service Crown amplifiers are quality units that rarely require servicing. Before returning your unit for service, please contact Crown Technical Support to verify the need for servicing. This unit has very sophisticated circuitry which should only be serviced by a fully trained technician. This is one reason why each unit bears the following label: CAUTION: To prevent electric shock, do not remove covers. No user serviceable parts inside.
