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 on line at www.crownaudio.com), Crown Customer Service, 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.

Setup

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

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 (counterstock-wise).
Use a standard 19-inch (48.3 cm) equipment rack. See Figure 3.1 for amplifier dimensions.
You may also stack amps without using a cabinet.
NOTE: When transporting, amplifiers should be supported at both front and back.

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 two 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 3.2 illustrates standard amplifier airflow.

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. Both channels should be wired using a common center terminal for ground connection.
NOTE: Custom wiring should only be performed by qualified personnel.

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.
If your CE 2000TX 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 CD 2000TX amplifiers .
If the CEAS1 Output Module is installed, use terminal forks or bare wire for your output connectors (see Figure 3.7).
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 3.8).
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.

Wire Your System

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 out-put 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.

How to Parallel the Inputs in Stereo Mode
There are three ways to feed the same signal to each amplifier channel:

1. Buy a “Y” cable. Plug the female end into your signal cable, and plug the split male ends into both amplifier inputs.

2. Feed your signal to the Channel-1 input
   (either barrier-block or Combo). Connect a jumper wire (Figure 3.10) between the barrier-block Channel-1 (+) screw terminal and the Channel-2 (+) screw terminal. Connect another jumper wire between the Channel-1 (–) screw terminal and the Channel-2 (–) screw terminal.

3. Feed your signal to the Channel-1 input screw terminals. Using a mic cable or phone-to-phone cable, connect Channel-1 Combo jack to Chan-nel-2 Combo jack.

See the next page for Bridge-Mono wiring.

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 3.5 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.

Figure 3.14
Typical Large 3-Way System (CE 2000TX Amplifiers Shown with Optional CEAS1 Output Module)

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. This setting works best when the amplifier is being driven by equipment with a +4 dBu output — an output level at which most professional equipment operates.
If required, the Input Sensitivity switch can be moved to the 26 dB position, so that the amplifier provides a fixed voltage gain of 20 (or 26 dB: 1 volt in, 20 volts out). This setting works best with output levels of +10 dBu (2.5 volts RMS) or more. Some brands of DJ mixers, in particular, have output levels in this range.
Selecting the correct sensitivity will allow your equipment to operate at its optimum level and improve the signal-to-noise of the system.
Make sure the amplifier is turned off and the level controls are turned down before you change the switch setting.

Connect to AC Mains
Connect your amplifier to the AC mains power source (power outlet) with the supplied AC power cord set. First, connect the IEC end of the cord set to the IEC connector on the amplifier; then, plug the other end of the cord set to the AC mains.
WARNING: The third prong of this connector (ground) is an important safety feature. Do not attempt to disable this ground connection by using an adapter or other methods.
Amplifiers don’t create energy. The AC mains volt-age and current must be sufficient to deliver the power you expect. You must operate your amplifier from an AC mains power source with not more than 10% variation above or below the amplifier’s specified line voltage and within the specified frequency requirements (indicated on the amplifier’s back panel label). If you are unsure of the output voltage of your AC mains, please consult your electrician.

Startup Procedure
Use the following procedure when first turning on your amplifier:

1. Turn down the level of your audio source.
2. Turn down the level controls of the amplifier.
3. Turn on the “Power” switch. The Power indicator-should glow.
4. Turn up the level of your audio source to an optimum level.
5. Turn up the Level controls on the amplifier until the desired loudness or power level is achieved.
6. Turn down the level of your audio source to its normal range.

If you ever need to make any wiring or installation changes, don’t forget to disconnect the power cord.
For help with determining your system’s optimum gain structure (signal levels) please refer to the Crown Amplifier Application Guide, available online at www.crownaudio.com.

Operation

Precautions
Your amplifier is protected from internal and external faults, but you should still take the following precautions for optimum performance and safety:

1. Before use, your amplifier first must be con-figured for proper operation, including input and output wiring hookup. Improper wiring can result in serious operating difficulties. For information on wiring and configuration, please consult the Setup section of this manual or, for advanced setup techniques, consult Crown’s Amplifier Application Guide available online at www.crownau-dio.com.
2. Use care when making connections, selecting signal sources and controlling the out-put level. The load you save may be your own!
3. Do not short the ground lead of an output cable to the input signal ground. This may form a ground loop and cause oscillations.
4. Never connect the output to a power supply, battery or power main. Electrical shock may result.
5. Tampering with the circuitry, or making unauthorized circuit changes may be hazardous and invalidates all agency listings.
6. Do not operate the amplifier with the red Clip LEDs constantly flashing.
7. Do not overdrive the mixer, which will cause clipped signal to be sent to the amplifier. Such signals will be reproduced with extreme accuracy, and loudspeaker damage may result.
8. Do not operate the amplifier with less than the rated load impedance. Due to the amplifier’s output protection, such a configuration may result in premature clipping and speaker damage.

Controls, Indicators and Connectors

Advanced Features and Options3

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.

Protection Systems
CE 2000TX amplifiers are protected against shorted, open or mismatched loads; over-loaded power supplies; excessive temperature; chain destruction phenomena; input overload damage; and high-frequency blowups. They also protect loudspeakers from input/output DC, large or dangerous DC offsets and turn-on/turn-off transients.

Bias Servo
Bias servo translates the output heatsink temperature to controlled bias current. This pre-vents thermal runaway and holds the amplifier’s notch distortion to a minimum.

Fault
The amplifier will light the Fault LED on the front panel if the amplifier output stage stops operating. If this happens, take the unit to an authorized service center.

Ultrasonic and Radio Frequency Protection
An amplifier’s slew rate only needs to be large enough to deliver the maximum voltage at the highest required frequency. Higher slew rates actually let the amplifier reproduce undesirable frequencies. By design, the CE 2000TX amplifier has a controlled slew rate to put a frequency limit on the highest frequencies that they reproduce. This limit occurs well above 20 kHz, so there is no audible effect on performance.

This approach protects the amplifier from radio frequencies and can even protect some sensitive loads (including some tweeters).

Drive Protection
This system temporarily removes output drive to protect the amplifier and its loads. Drive protection can be activated in two situations. First, if dangerous subsonic frequencies or direct current (DC) is detected in the amplifier’s out-put, drive protection will activate. The amplifier resumes normal operation when it no longer detects dangerous output. Activating this protection is very unlikely, but improper source signals like infrasonic square waves or a severely clipped input signal can activate this system.
Second, the amplifier’s fault protection system puts the affected channel into drive protection mode in rare situations where heavy common-mode current is detected in its output. The amplifier should never output heavy common-mode current unless its circuitry is damaged. Activating drive protection helps prevent further damage.

Compression
A full-time compressor is in-line with the signal, preventing damage to your speakers.

Power Circuit Breaker
A front panel push button is used to reset the circuit breaker that protects the power supply.

Proportional-speed Fan
The speed of the cooling fan is controlled by the transformer temperature and the heatsink temperature.

Advanced Features
Crown SST Modules
Crown optional SST (System Solution Topologies) modules were specially designed to improve the fidelity and versatility of your audio system. They feature a variety of professional signal routing and filtering capabilities, with active crossovers that allow the audio signal to be split and sent to auxiliary amplifiers. Your amplifier may have come with an SST module already factory-installed, or your choice of SST modules can be easily added to the amplifier by any authorized Crown Service Center.
For information on wiring and configuration of amplifiers equipped with an optional Crown SST crossover module, please refer to the SST Crossover Reference Manual included in your literature package.
Refer to the following descriptions for an over-view of available Crown SST crossover modules. Crown plans to release additional accessory plug-in modules offering a range of advanced features and capabilities. Watch for new releases.

SST-SBSC-3632T
This is a custom three-channel crossover net-work 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.

Features:

• High-frequency signals are internally routed to the channel-one amplifier input, and mid-frequency signals are routed to the channel-two amplifier input.
• Mono summing of low-frequency signals are routed from Output B to an external amplifier.
• Neutri®k Combo jacks for balanced input connection.
• Removable barrier block connectors for balanced output to other components.

SST-SBSC 4632T
Like the SST-SBSC 3632T but for the JBL 4632T cinema speakers.

SST-4622

Additional features include:

• Time correction via an all-pass analog delay ensures coherent summation through the crossover region, while maintaining optimal vertical polar response.

SST-4632
Like the SST-36-32 but for the JBL 4632 cinema speaker systems.

Fault Monitoring
The Fault (RJ-11) jack, which looks like a tele-phone 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.
When using this circuit, the LED will glow whenever the amplifier is in one of four states: a channel’s heatsink has reached its temperature limit, the transformer has reached its temperature limit, the amplifier has just been turned on and is in its turn-on-delay mode, or the amplifier is turned off.

If you choose to design your own circuit to interface this signal to your system, note that this RJ jack is polarity sensitive. Pin 2 must be grounded, and Pin 5 must be supplied with a positive voltage pull up (positive with respect to ground). Refer to Figure 5.4 for RJ jack pin assignments. The maximum signal that can be exposed to the fault jack is 35VDC and 10 mA. Best results are obtained with 10 mA LEDs.
The mating connector for the CE 2000TX RJ-11 jack contains 4 contact pins in a 6-slot case, as shown. For additional information please con-tact your local dealer or Crown Technical Support.

Options
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. For more information, please contact Crown Technical Sup-port.

Tamper-Resistant Hole Plugs
Your CE 2000TX amplifier comes with a set of tamper-resistant hole plugs, which allow you to “protect” the level controls against unauthorized adjustment. To use, simply pull off the control knobs from the front of the amp, and slip the hole plugs into place (see Figure 5.7). The plugs should press easily into position with light force. Once in place, the plugs will help to avoid most accidental or intentional tampering (some situations may require additional security measures).
To remove the hole plugs, simply pry the plug away from the amplifier case using a small, flat-blade screwdriver. To help to ensure adequate security, the plugs have been designed to be more difficult to remove than to place into position. If necessary, additional hole plugs can be purchased separately from Crown’s Parts Department (Part # 103234-1).
Store your knobs in a safe location should you need to make level adjustments in the future.

Optional 0.775V Input Sensitivity Setting
The CE 2000TX amplifier also provides an optional 0.775V input sensitivity setting. If you determine your application requires this sensitivity setting, please contact Crown Technical Support for more information.

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. The signal is then converted from balanced to unbalanced in the Balanced Input Stage where it also receives RFI protection. Signal then flows into the Variable Gain Stage where the front panel level controls are allowed to affect the gain.
Following this stage, the signal is put under the control of a full-time compressor circuit comprised of a symmetrical window detector, a buffer amplifier, and the gating op amp which uses several small components to set the compressor’s attack and decay characteristics. The actual compressing is accomplished by an opto-isolator which affects the gain in the sig-nal path.
Next the signal enters the error amplifier circuit, where it is mixed with a small portion of the output signal in such a way as to control the amplifier’s overall output performance.
Following the error amp is the LVA stage, which is where the low-voltage referenced signal gets translated to the output high-voltage rails. The last voltage amplifier, in conjunction with a bootstrap current source, drives both predrivers and the bias servo. The bias servo is mounted in such a way as to translate the out-put heatsink temperature into a controlled bias current to prevent thermal runaway and hold the amplifier’s notch distortion to a minimum.

The redrives provide enough signal to activate the drivers, which together operate in the class AB range. For the major output current requirements, the drivers feed the various numbers of paralleled output transistors which operate in a class B mode. This we call the Triple-Deep Darlington Output Stages.
The output transistors are protected by the Time Dependent Voltage & Current circuit. This circuit protects the devices from extending beyond their safe area of operation, but allows the devices to provide high bursts of peak power with music, allowing your amplifier to deliver more punch. When all is said and done, this amplifier output topology offers a good combination of low quiescent amplifier heating, great distortion performance at high powers, and relative simplicity, with impressive reliability and value.
All output power is delivered through 4-circuit Speakon® connectors. These connectors have been wired in such a way as to allow you the most versatility. The Channel 1 and 2 connectors are cross wired so you can cover all options, from dual cable stereo (typical), to Bridge-Mono in one connector, to running a bi-amp speaker with one amplifier and one cable per speaker cabinet.
The output relay, in conjunction with input signal mute circuit, assures the amplifier will be well-behaved during turn on and off. In the event of an amplifier output failure, a triac will activate to turn off the offending channel and protect your speakers.
The turn on delay circuit functions to keep the output relay open until all the voltages are up and stable, both in the amplifier, and in all the components in the system ahead of the amplifier.
Heatsink temperature is monitored by a thermal probe attached to the heatsink. As the temperature rises, the probe sends a proportional cur-rent to the proportional speed fan circuit which

starts the fan. Should the power transformer reach its maximum safe temperature, an internal thermal switch opens and the fan circuit turns on full speed to quickly cool down the amplifier. It also disconnects the load via the output relay, removing any output current and further speeding a cool- down cycle. Extra care was taken during the design stage to set this point both to protect your investment and to guard against nuisance tripping.
Whenever the heatsinks or the transformer reach a maximum temperature, or during the normal turn-on delay window, the front panel Fault LEDs will blink to get your attention.
A modular jack is mounted on the back panel (same type as used on telephones). Pins 2 and 5 are connected to an opto-isolator which is always in a low- resistance state whenever the unit is on and happy. Should a fault be detected or should the amplifier lose AC power, the opto-isolator will change to a high resistance, allowing the user to remotely detect the status of the amplifier.
The Signal Presence Indicators tap the signal chain just before the level controls and prior to the power amplifier chain. They are not ampli-ier output indicators and should only be used to indicate the presence of signal to the amplifier front end.
The Clip light is driven from the output of the compressor circuitry and lights to indicate the onset of audible distortion.
The Power LED is driven from the low-voltage supply.
A positive and negative regulator form the ±15-volt power supplies. Add to that the main trans-former, a full-wave bridge rectifier, and high energy electrolytic to form the main power sup-ply. They are protected by the front- panel line circuit breaker and controlled by the front-panel power switch.

Troubleshooting

CONDITION: Power indicator is off.

POSSIBLE REASON

• The amplifier has lost AC power.
• The amplifier’s Power switch is off.
• The amplifier’s power cord is not plugged in at either end.
• The amplifier’s circuit breaker has tripped. Allow the amplifier to cool; remove excessive loads, and press the reset switch on the front panel.

CONDITION: No input signal (Signal indicator is not flashing even though audio is applied).

POSSIBLE REASON:

• Input signal level is very low.
• Master audio from mixer turned down.
• Input cable broken or not plugged in.

CONDITION: Fault indicator is flashing.

POSSIBLE REASON:

• The amplifier has just been turned on and is still in the 4-second turn-on delay.
• The heatsinks are too hot.
• The transformer thermal protection is activated.
• The amplifier output wires have developed a short circuit.
• The amplifier output stage has stopped operating. Refer the unit to an authorized Crown Ser-vice Center

The fault status of the amplifier can also be monitored remotely by attaching a signal device to the Fault jack located on the amplifier back panel. See the Advanced Features and Options section for more detail.

CONDITION: Distorted sound.

POSSIBLE REASON:

• Load is wired incorrectly or Stereo/Mono mode switch is set incorrectly. Check both.
• Input signal level is too high. Turn down your amplifier level controls, or turn down the input signal, until the clip LED goes out.

Note: If sound is distorted but clip LED is not flashing, check mixer levels and gain staging, mixer clip lights, and pads built into microphones.

CONDITION: Input signal but no sound.

POSSIBLE REASON:

• Speakers not connected. Make sure the Neutrik NL4 connector is fully seated and locked.
• The amplifier output level is so high that the breaker has tripped. Try to identify and correct the problem before resetting the breakers. If the problem persists, refer the unit to an authorized Crown Service Center.

Service

Crown amplifiers are quality units that rarely require servicing. Before returning your unit for service, please con-tact 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. Refer servicing to a qualified technician.
Complete the Crown Audio Factory Service Information form, in the back of this manual, when returning a Crown product to the factory or authorized service center.
