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

3.6 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.

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

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.
