3.3 Ensure Proper Cooling  
3.2 Install Your Amplifier  
3.1 Unpack Your Amplifier  
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.  
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 (counterclock-  
wise).  
Please unpack and inspect your amplifier for  
any damage that may have occurred during  
transit. If damage is found, notify the transpor-  
tation company immediately. Only you can ini-  
tiate 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.  
Use a standard 19-inch (48.3 cm) equipment  
rack. See Figure 3.1 for amplifier dimensions.  
Figure 3.2 illustrates standard amplifier airflow.  
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 may also stack amps without using a  
cabinet.  
NOTE: When transporting, amplifiers should be  
supported at both front and back.

3 Setup  
3.5 Choose Output Wire and Con-  
nectors  
Crown recommends using pre-built or profes-  
sionally wired, high-quality, two- or four-con-  
ductor, heavy gauge speaker wires. They should  
be terminated with Neutrik Speakon NL4FC con-  
nectors (Figure 3.6) at one end and appropriate  
connectors to fit your speakers at the other end.  
Figure 3.6 Neutrik® Speakon® Connector  
If your CE 2000TX amplifier came equipped with  
the CEAS1 (barrier strip) or CEAS2 (5-way bind-  
ing 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 ter-  
minal forks or bare wire for your output connec-  
tors (see Figure 3.7).  
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 3.8).  
Using the guidelines below, select the appropri-  
ate size of wire based on the distance from  
amplifier to speaker.

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.  
SHOWN WITH OPTIONAL CEAS1 OUTPUT MODULE  
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 con-  
nector pin assignments. Make sure the Mode  
switch is set to the “Stereo” position when oper-  
ating 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.  
Figure 3.9 Typical System Wiring, Stereo Mode  
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.

4.1 Precautions  
Your amplifier is protected from internal and  
external faults, but you should still take the fol-  
lowing precautions for optimum performance  
and safety:  
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 equip-  
ment operates.  
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.  
WARNING: The third prong of this connec-  
tor (ground) is an important safety feature.  
Do not attempt to disable this ground con-  
nection by using an adapter or other meth-  
ods.  
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 configura-  
tion, please consult the Setup section of this  
manual or, for advanced setup techniques,  
consult Crown’s Amplifier Application  
dio.com.  
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 speci-  
fied line voltage and within the specfied 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.  
If required, the Input Sensitivity switch can be  
moved to the 26 dB position, so that the ampli-  
fier 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.  
2. Use care when making connections, select-  
ing signal sources and controlling the out-  
put level. The load you save may be your  
own!  
Selecting the correct sensitivity will allow your  
equipment to operate at its optimum level and  
improve the signal-to-noise of the system.  
3.9 Startup Procedure  
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.  
Use the following procedure when first turning on  
your amplifier:  
Make sure the amplifier is turned off and  
the level controls are turned down before  
you change the switch setting.  
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. Never connect the output to a power  
supply, battery or power main. Elec-  
trical shock may result.  
4. Turn up the level of your audio source to an opti-  
mum 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.  
5. Tampering with the circuitry, or making  
unauthorized circuit changes may be haz-  
ardous 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.  
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  
8. Do not operate the amplifier with less than  
the rated load impedance. Due to the ampli-  
fier’s output protection, such a configuration  
may result in premature clipping and  
speaker damage.

5 Advanced Features  
and Options  
5.2 Advanced Features  
This approach protects the amplifier from radio  
frequencies and can even protect some sensi-  
tive loads (including some tweeters).  
NOTE: For detailed information about  
these Crown amplifier features, please  
consult the Crown Amplifier Application  
Guide, available on the Crown website  
5.2.1 Crown SST Modules  
Crown optional SST (System Solution Topolo-  
gies) 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.  
5.1.4 Drive Protection  
This system temporarily removes output drive  
to protect the amplifier and its loads. Drive pro-  
tection 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 pro-  
tection is very unlikely, but improper source  
signals like infrasonic square waves or a  
severely clipped input signal can activate this  
system.  
5.1 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.  
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.  
5.1.1 Bias Servo  
Bias servo translates the output heatsink tem-  
perature to controlled bias current. This pre-  
vents thermal runaway and holds the amplifier’s  
notch distortion to a minimum.  
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.  
Refer to the following descriptions for an over-  
view of availabe Crown SST crossover mod-  
ules. Crown plans to release additional  
accessory plug-in modules offering a range of  
advanced features and capabilities. Watch for  
new releases.  
5.1.2 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.  
5.1.5 Compression  
A full-time compressor is in-line with the sig-  
nal, preventing damage to your speakers.  
5.1.3 Ultrasonic and Radio Fre-  
quency 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 ampli-  
fier has a controlled slew rate to put a fre-  
quency limit on the highest frequencies that  
they reproduce. This limit occurs well above 20  
kHz, so there is no audible effect on perfor-  
mance.  
5.1.6 Power Circuit Breaker  
A front panel push button is used to reset the  
circuit breaker that protects the power supply.  
5.1.7 Proportional-speed Fan  
The speed of the cooling fan is controlled by  
the transformer temperature and the heatsink  
temperature.

CE2000TX Power Amplifier  
5 Advanced Features  
and Options  
5.2.2 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 tempera-  
ture limit, the amplifier has just been turned on  
and is in its turn-on-delay mode, or the ampli-  
fier is turned off.  
Figure 5.2 Location of Fault Jack  
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.

and Options  
additional hole plugs can be purchased separately  
from Crown’s Parts Department (Part # 103234-1).  
5.3 Options  
5.3.1 Alternate Output Connectors  
Store your knobs in a safe location should you need  
to make level adjustments in the future.  
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.  
5.3.3 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.  
Figure 5.5 Model CEAS1 Barrier Block  
Output Connectors  
5.3.2 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).  
Figure 5.6 Model CEAS2 5-way  
Binding Post Output Connectors  
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,

CE2000TX Power Amplifier  
6 Principles of Operation  
starts the fan. Should the power transformer  
reach its maximum safe temperature, an inter-  
nal 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.  
The predrivers provide enough signal to acti-  
vate the drivers, which together operate in the  
class AB range. For the major output current  
requirements, the drivers feed the various num-  
bers of paralleled output transistors which  
operate in a class B mode. This we call the Tri-  
ple-Deep Darlington Output Stages.  
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 stan-  
dard 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.  
The output transistors are protected by the Time  
Dependent Voltage & Current circuit. This cir-  
cuit 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 reliabil-  
ity and value.  
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.  
Following this stage, the signal is put under the  
control of a full-time compressor circuit com-  
prised of a symmetrical window detector, a  
buffer amplifier, and the gating op amp which  
uses several small components to set the com-  
pressor’s attack and decay characteristics. The  
actual compressing is accomplished by an  
opto-isolator which affects the gain in the sig-  
nal path.  
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 connec-  
tors 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 Signal Presence Indicators tap the signal  
chain just before the level controls and prior to  
the power amplifier chain. They are not ampli-  
fier output indicators and should only be used  
to indicate the presence of signal to the ampli-  
fier front end.  
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 perfomance.  
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 predriv-  
ers 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 output relay, in conjunction with input sig-  
nal 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 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.  
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.  
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.  
Heatsink temperature is monitored by a thermal  
probe attached to the heatsink. As the tempera-  
ture rises, the probe sends a proportional cur-  
rent to the proportional speed fan circuit which

7 Troubleshooting  
CONDITION: Power indicator is off.  
CONDITION: Distorted sound.  
POSSIBLE REASON:  
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.  
Input signal level is too high. Turn down your  
amplifier level controls, or turn down the input  
signal, until the clip LED goes out.  
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.  
Note: If sound is distorted but clip LED is not flash-  
ing, check mixer levels and gain staging, mixer clip  
lights, and pads built into microphones.  
CONDITION: No input signal (Signal indi-  
cator is not flashing even though audio is applied).  
POSSIBLE REASON:  
CONDITION: Input signal but no  
sound.  
Input signal level is very low.  
Master audio from mixer turned down.  
Input cable broken or not plugged in.  
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 autho-  
rized Crown Service Center.  
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 operat-  
ing. Refer the unit to an authorized Crown Ser-  
vice Center  
The fault status of the amplifier can also be moni-  
tored 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.
