CE 4000
CE SERIES
Engineered from the bottom up for top-
notch performance and unmatched reli-
ability, the Crown®CE 4000 amplifier
represents the wave of the future for power
amplifiers. Designed using Crown’s patented,
award-winning Class I (BCA®Balanced Current
Amplifier) engineering, the CE 4000 provides
superior power output, increased efficiency,
legendary Crown sound and extraordinary reli-
ability.
The CE 4000 not only handles but excels at
2-ohm loads. In repeated stress tests, the CE
4000 continued to perform at levels 12 dB into
clip, long after the competition had shut down.
Designed for the utmost in flexibility, the CE
4000 features selectable on-board high-and
low-pass filter sets, so you can easily add
a sub-bass system. Additional signal control
is available via Crown’s optional SST (System
Solution Topologies) modules, which offer a
wide variety of active crossover configurations.
Your choice of dual output connectors is also
available: Neutrik®Speakon®plus 5-way bar-
rier block, 5-way barrier block plus binding
strip, or dual Neutrik Speakon.
Weighing in at a mere 34 pounds, the CE 4000
is easy to transport and set up. What’s more,
Crown’s enhanced, switch-mode power supply
(featuring power factor correction) results in a
universal power supply, so you can plug it in
anywhere. And with the lowest cost per watt of
any amp in its class, the CE 4000 is the obvi-
ous choice for serious musicians everywhere.

Mode: Turn power off before switching. A two-
position switch located on the back panel below
the input connectors which, when turned to

dent channels. When “Bridge-Mono” mode is
selected, the amplifier bridges the two output
channels for twice the output voltage.
Sensitivity: A three-position switch located on
the back panel next to the Mode switch. Switch-
able among 0.775 volts or 1.4 volts for full
output into an 8-ohm load (default setting), or
3.46 volts for a fixed voltage gain of 26 dB.
Fault Jack: A back-panel RJ-11 jack that may
be remotely monitored to signal amplifier Fault
condition. An LED or other signalling device
(not supplied) may be used.*
Filter Switches:
Low Pass: A three-position switch for each
channel located on the back panel below
the input and output modules. Switchable
among settings for Flat, 80 Hz and 100 Hz.
Filter rolloff is 24 dB per octave.
High Pass: A four-position switch for each
channel located on the back panel below
the input and output modules. Switchable
among settings for Flat, 30 Hz, 40 Hz and 50
Hz. Filter rolloff is 18 dB per octave.

Crown’s Three-Year, No-Fault, Fully Transferable Warranty
Crown offers a Three-Year, No-Fault, Fully Transferable Warranty for every new Crown ampli-
fier—an unsurpassed industry standard. With this unprecedented No-Fault protection, your new
Crown amplifier is warranted to meet or exceed original specifications for the first three years of
ownership. During this time, if your amplifier fails, or does not perform to original specifications,
it will be repaired or replaced at our expense. About the only things not covered by this warranty
are those losses normally covered by insurance and those caused by intentional abuse. And the
coverage is transferable, should you sell your amplifier.
See your authorized Crown dealer for full warranty disclosure and details. For customers outside
of the USA, please contact your authorized Crown distributor for warranty information or call
574-294-8200.
CE 4000
Indicators
Signal: A green LED for each channel which
flashes when a very low-level signal (> –40
dBm) is present at input. May be used for
troubleshooting cable runs.
Clip: A red LED for each channel which turns
on when distortion becomes audible in the
amplifier output.
Fault: Normally off, this red indicator will blink
under five different conditions:
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.
4. If amplifier output wires develop a short-
circuit.
5. Should the amplifier output stage become
non-operational.
This circuit may be monitored remotely by
plugging a simple switching circuit using an
LED or other signaling device into the back-
panel RJ-11 (Fault) jack. Under some condi-
tions, the output of the amplifier will be muted.
Power: A green LED that turns on when the
amplifier has been turned on and has power.
Input/Output
Input Connector (standard module): One Neu-
trik Combo connector for each channel which
features a balanced ¼-inch (6.35-mm) phone
jack and a 3-pin female XLR connector, in paral-
lel with a barrier strip termination.
Input Stage: Input is electronically balanced
and employs precision 1% resistors.
Input Impedance: Nominally 20 k ohms, bal-
anced. Nominally 10 k ohms, unbalanced.
Input Sensitivity: 0.775 volts or 1.4 volts for
standard 1 kHz power, or fixed 26-dB gain.
Output Connectors (three options available):
CE4D Module: Two 5-way binding posts
in parallel with two Speakon®connectors
(standard domestic configuration).
CE4E Module: Four Neutrik Speakon®
NL4MP (mates with NL4FC) output connec-
tors (standard export configuration).
CE4C Module: Barrier strip outputs in paral-
lel with two 5-way binding posts.
Speakon®Wiring Configuration:
Output Signal:
Stereo: Unbalanced, two-channel.
Bridge-Mono: Balanced, single-channel.
Channel 1 controls are active; Channel 2
should be turned down.
Protection
CE 4000 amplifiers are protected against
shorted, open or mismatched loads; overloaded
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 tran-
sients.
Construction
Rugged steel chassis is formed into a durable
package. Coated with environmentally friendly
powder for long life and ease of maintenance.
Cooling: Three-speed Fan On Demand.
Dimensions: EIA Standard 19-inch rack mount
width (EIA RS-310-B), 5.25 inches (13.34 cm)
high and 16.25 inches (36.56 cm) deep with
additional 1-inch rear rack ears.

Options
SST Modules
Crown’s optional SST (System Solution Topolo-
gies) modules can improve the fidelity and ver-
satility of your audio system. They feature a
variety of professional signal routing and filter-
ing capabilities. 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 more information, visit the
Crown website at www.crownaudio.com.
