Balanced Line  
Unbalanced Line  
Crown recommends using pre-built or profes-  
sionally wired, balanced line (two-conductor  
plus shield), 22-24 gauge cables and connec-  
tors. Depending upon which amplifier input  
you choose, you should use either 3-pin male  
XLR connectors, TRS phone connectors, or ter-  
minal forks at the amplifier inputs.  
Unbalanced line may also be used but may  
result in noise over long cable runs.  
Note: Amplifier input connectors not used  
for audio signal input may be used for  
daisy-chaining of the audio signal to other  
components.  
Refer to Figure 3.3 for correct connector pin  
assignments for balanced wiring, and Figure

3 Setup  
3.6 WireYour 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. Make sure the  
Mode switch set to the “Stereo” position when operating in Stereo mode.  
3.6.2 How to Parallel the Inputs  
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 3.9) 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 3.8 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 Channel-2  
combo jack.  
3.6.3 Bridge-Mono Mode  
Typical input and output wiring is shown in Figure 3.10.  
INPUTS: Connect input wiring to Channel 1.  
OUTPUTS: Connect the speaker across the positive terminals of each chan-  
nel. Do not use the negative terminals when the amp is being operated in  
Bridge-Mono mode. Refer to Section 3.6 for output connector pin assign-  
ments. Make sure the Mode switch is set to the “Bridge” position when  
operating in Bridge-Mono mode.  
NOTE: The Channel 2 level control should be set fully counter-  
clockwise when operating the amplifier in Bridge-Mono mode.

4.1 Precautions  
4. Never connect the output to a  
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.  
Your amplifier is protected from internal and  
external faults, but you should still take the fol-  
lowing precautions for optimum performance  
and safety:  
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.  
1.  
Before use, your amplifier first must be  
configured for proper operation, includ-  
ing 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 tech-  
niques, consult Crown’s Amplifier  
Application Guide available online at  
WARNING: The third prong of this con-  
nector (ground) is an important safety  
feature. Do not attempt to disable this  
ground connection by using an adapter  
or other methods.  
6.  
7.  
Do not operate the amplifier with the  
red Clip LEDs constantly flashing.  
Do not overdrive the mixer, which will  
cause clipped signal to be sent to the  
amplifier. Such signals will be repro-  
duced with extreme accuracy, and loud-  
speaker damage may result.  
Amplifiers don’t create energy. The AC mains  
voltage 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 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.  
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.  
2.  
3.  
Use care when making connections,  
selecting signal sources and controlling  
the output level. The load you save may  
be your own!  
Do not short the ground lead of an  
output cable to the input signal ground.  
This may form a ground loop and cause  
oscillations.  
Remember: Crown is not liable for  
damage that results from overdriving  
other system components.  
3.8 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 ampli-  
fier.  
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 ampli-  
fier 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 instal-  
lation changes, don’t forget to disconnect  
the power cord.  
For help with determining your system’s opti-  
mum gain structure (signal levels) please refer

The Fault status of the amplifier can also be

Application Guide, available on the Crown  
ent enough from other amplifier classes that  
it received a patent and merits it’s own class  
designation, “class-I.”  
BCA technology offers several key advantages.  
It provides unprecedented efficiency, requiring  
less power from the AC supply than other  
designs, meaning significant cost savings over  
the life of the amplifier. BCA handles reactive  
speaker loads easily and gracefully, by reusing  
energy returned from the speaker rather than  
dissipating it as heat or forcing the amp into  
premature current-limiting. This ability makes  
BCA models extremely resilient—especially at  
low, 2-ohm impedances. It also makes them  
more reliable, since they are not constantly  
stressed to their limits or subjected to exces-  
sive heat. Best of all, as proud owners can  
attest, amps with BCA technology sound great,  
with a powerful low-end that stands out from  
the competition.  
5.1 Protection Systems  
Your Crown amplifier provides extensive pro-  
tection and diagnostic capabilities, including  
built-in anti-clip limiters, amplifier fault protec-  
tion, and switchable high-pass filters.  
Figure 5.2  
Fault Jack  
5.1.1 Anti-Clip Limiters  
5.1.3 High-Pass Filters  
Your Crown amplifier has built-in Anti-Clip  
Limiters which offer a degree of protection  
to your loudspeakers. The Anti-Clip Limiters  
work by dynamically reducing the amplifier  
gain if the output stage is driven into clip,  
thereby reducing potentially damaging distor-  
tion to moderate levels.  
Very low frequency signals contain no useful  
musical energy, waste valuable amplifier power  
and headroom, and can be damaging to  
your speakers. Your Crown amplifier provides  
switchable high-pass filters to remove these  
signals from each channel’s output.  
For each channel, a back-panel, three-position  
switch provides optional settings of Flat, 30  
Hz, 40 Hz, or 50 Hz (left to right, see Figure  
5.3). The 30 Hz setting is suitable for all  
full-range and low-frequency applications. The  
lower-frequency settings may be selected when  
the amplifier is being used to drive a sub-bass  
program; use only with speakers that provide a  
useful frequency response below the frequency  
setting. The FLAT setting provides bypass of  
the high-pass filters, for use when subsonic  
protection is provided elsewhere in the system.  
While some audio systems may already con-  
tain protective limiters preceeding the amplifier  
in the system, the amplifier’s Anti-Clip Limiters  
generally will not noticeably affect output qual-  
ity. For systems without additional protection,  
the Anti-Clip Limiters can enhance your sys-  
tem’s output quality and prevent catastrophic  
damage to your speakers.  
5.2.2 Switching Power Supply with  
PFC  
Crown’s new Switching Power Supply with PFC  
provides a range of benefits over both non-  
switching and conventional switching power-  
supply designs.  
Figure 5.3 High-  
Pass Filter Switch  
Typical non-switching power supplies require  
large, heavy transformers in order to produce  
the required power at the output stage. These  
transformers must be large to absorb the sub-  
stantial waste that occurs when operating at 50  
to 60 Hz (standard AC supplied by the power  
company).  
Even with the Anti-Clip Limiters, your amplifier  
should never be operated at a level which  
causes the front-panel Clip LEDs to illuminate  
constantly. While the Anti-Clip Limiters help to  
prevent damage due to signal distortion, your  
speakers can still be damaged by excess power  
dissipation.  
5.2 Circuit Designs  
5.2.1 BCA  
BCA (Balanced Current Amplifier) is Crown’s  
patented, cutting-edge technology that gets  
more power out of an amplifier with less waste  
than was ever before possible. A completely  
new adaptation of standard amplifier design,  
Crown’s BCA “switching” amplifier design pro-  
vides for high output, exceptional reliability  
and nearly twice the efficiency of typical ampli-  
fier designs.  
By contrast, switching power supplies can  
operate with a much smaller (and lighter)  
transformer because they first convert the AC  
up to a much higher frequency, thereby reduc-  
ing waste.  
5.1.2 Fault  
The amplifier will light the Fault LED (Figure  
5.1) of an amplifier channel under five different  
conditions:  
However, in both non-switching and conven-  
tional switching designs, phase differences  
occur within the power supply due to the  
inductance of the transformer. This phase dif-  
ference prevents much of the available power  
from the AC mains from making its way to the  
load.  
1. When the amplifier is first powered up,  
until the unit is ready for operation.  
2. If the heatsinks reach a temperature above  
normal working limits.  
3. If the transformer thermal protection cir-  
cuit is activated.  
Crown’s BCA “switching” technology is a com-  
pletely new adaptation of standard switching  
(PWM) amplifier design. In fact, BCA is differ-

CE 4000 Power Amplifier  
5.3.2 Neutrik Speakon Wiring  
5.4.2 Output Connectors  
PFC, however, compensates for phase differ-  
ences 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.  
The Neutrik Speakon NL4 connector is a four-  
pole type, which allows either one or two sets  
of speakers to be wired to one connector.  
Figure 5.5 shows the wiring pin assignments.  
For added system flexibility, Crown offers  
optional output connector configurations for  
your amplifier. If you prefer, you can choose  
to have dual Neutrik Speakon® output connec-  
tors (model CE4E) or 5-way binding post plus  
barrier strip (model CE4C) connectors installed  
in your amplifier in place of the standard Neu-  
trik Speakon® plus 5-way binding post outputs  
(model CE4D) at time of ordering. For informa-  
tion on adding optional output connector mod-  
ules to an existing CE 4000 amplifier, please  
contact Crown Technical Support (see Section  
8 for contact information).  
As an added benefit, PFC also allows the amp  
to be connected to any common AC line volt-  
age, without converting the power supply. This  
means that whether you’re running one or two  
amps on a household circuit or several amps  
on a power distro, your CE 4000 amplifiier is  
ready—right out of the box.  
5.3 Other Features  
Figure 5.5 Speakon Pin Assignments  
5.4.3 Handle Kit  
5.3.1 Low Pass Filters  
Handles complement your amplifier’s appear-  
ance, aid in transportation, and the placement  
in or removal from racks. They are available  
from Crown’s Sales Department.  
5.4 Options  
For each channel, a back-panel, three-position  
switch provides optional settings of Flat (Left),  
80 Hz (center) and 100 Hz (right) with an  
18-dB per octave rolloff (see Figure 5.4). The  
80- and 100-Hz settings may be selected when  
the amplifier is being used to drive a bass  
program. The FLAT setting provides bypass  
of the low-pass filters, for use either when a  
crossover is provided elsewhere in the system,  
or when the signal is full-range.  
5.4.1 SST Modules  
Crown’s optional SST (System Solution Topol-  
ogies) modules were specially designed to  
improve the fidelity and versatility of your  
audio system. They feature a variety of pro-  
fessional signal routing and filtering capabili-  
ties. 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 available  
SST modules, visit the Crown website at

6 Troubleshooting  
CONDITION: Normal operation.  
POSSIBLE REASON:  
CONDITION: No sound.  
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.  
The amplifier is in “fault” mode. A Fault  
status can be triggered when one of the  
amplifier’s protection circuits is activated.  
First disconnect your speakers from the  
affected channel(s) one by one to deter-  
mine if one of the loads is shorted. If the  
indicators return to normal status, then try  
a different speaker or cable to determine  
where the short is occurring. If no short  
can be found, turn off the amp and allow  
the amp to cool. If indicators do not return  
to normal after restarting your amp, check  
the fuse and replace if necessary, or return  
amp to Crown or an authorized Crown  
Service Center for servicing.  
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. Return amp to Crown or  
an authorized Crown Service Center for  
servicing.  
No input signal.  
Input signal level is very low.  
Level controls are turned down.  
CONDITION: Distorted sound.  
POSSIBLE REASON:  
Input signal level is too high. Turn down  
your amplifier level controls. NOTE: Your  
amplifier should never be operated at  
a level which causes the Clip LEDs to  
illuminate constantly.
