CE 2000
CE-SERIES
T he CE-Series of Crown amplifiers
are professional tools designed and
built for professional use. Engineered
and manufactured by the same teams who
built Crown’s acclaimed Macro-Tech® and K-
Series amps, the CE 2000 has the rugged
heart and soul that have characterized
Crown’s amplifiers for over 30 years.
With many of the same controls and features
you’ve come to expect from Crown, CE-
Series amplifiers feature front-panel detented
level controls, useful function indicators,
proportional fan-assisted cooling, short-
circuit protection and more.
For superior flexibility, Crown CE-Series
amplfiers can work with a range of Crown
SST (System Solution Topologies) modules
which provide true professional features like
fixed-point crossover and summed bass
output.
With a powerful, reliable performance, CE-
Series amps easily handle real 2-ohm loads
and are capable of chest-thumping lows.
Plus, your investment in an CE-Series ampli-
fier is backed by Crown’s unequaled Three-
Year, No-Fault, Fully Transferable Warranty
that covers everything.

at 800-342-6939 or 219-294-8200. Also,

Specifications
Note: All measurements relate to 120-volt, 60-Hz units in
Stereo mode with 8-ohm loads and an input sensitivity of 26-
dB gain at 1-kHz rated power unless otherwise specified.
Specifications for units supplied outside the U.S.A. may vary
slightly at different AC voltages and frequencies.
Power
Output Power:
Features
• Accurate, uncolored sound with very low dis-
tortion for the best in music and voice repro-
duction.
• Bridge-mono/stereo mode switch allows you
to set up your amps/speakers in the configu-
ration that best suits your needs.
• Advanced protection circuitry guards against:
shorted outputs, open circuits, DC, mis-
matched loads, general overheating, high-
frequency overloads and internal faults.
• Extremely versatile, handling a wide range
of speaker impedances and outputs.
• Switchable input sensitivity.
• Proportional speed fan optimizes cooling effi-
ciency.
• Shallow rack depth. Only 12.25 inches deep!
• Choice of Speakon®, binding post, or barrier
strip outputs (Speakon® comes standard).
• Choice of balanced 1/4-inch (6.35-mm), XLR,
or barrier strip inputs.
• The best Three-Year, No-Fault, Fully Transfer-
able Warranty in the business! It even covers
round-trip ground shipping in the U.S. for all
warranty work.
Load Impedance: Safe with all types of
loads. Rated for 2, 4 and 8 ohms in Stereo
mode, 4 and 8 ohms in Bridge-Mono mode.
Voltage Gain to 1-kHz, 8-ohm rated output:
32.1-dB gain at 1.4-volt sensitivity;
26-dB gain at 2.83-volt sensitivity.
Required AC Mains: 50/60 Hz (North Ameri-
can units are 60 Hz only); 100-, 120- and
230-/240-VAC (±10%) units are available.
AC Line Current,
100 Volts: 11.4 A;
120 Volts: 9.5 A;
230-240 Volts: 5.0 A;
At Idle: All amps draw no more than 90
watts.
AC Line Connector: NEMA 5-15P (15 A).
Performance
Frequency Response: ±0.2 dB from 20 Hz to
25 kHz at 1 watt.
Phase Response: ±15 degrees from 20 Hz to
20 kHz at 1 watt.
Signal to Noise Ratio,
A-Weighted:
Better than 105 dB below rated 1-kHz
power;
20 Hz to 20 kHz:
Better than 100 dB below rated 1-kHz
power.
Total Harmonic Distortion (THD): 0.5% or
less true THD from 20 Hz to 20 kHz.
Intermodulation Distortion (IMD): (60 Hz
and 7 kHz at 4:1) Less than 0.1% at rated
power to 35 dB below rated power at 8 ohms.
Damping Factor: Better than 400 from 10 Hz
to 400 Hz.
Crosstalk: Better than 55 dB below rated
power, 20 Hz to 20 kHz.
Common Mode Rejection (CMR): Greater
than 70 dB from 20 Hz to 1 kHz.
DC Output Offset (Shorted Input): ±10 mV.
Controls and Connectors
Level: A detented rotary level control for each
channel located on the front panel.
Power: An on/off rocker switch located on the
front panel.
Mode: A two-position switch located on the
back panel below the input connectors which,
when turned to stereo, operates the amplifier
as two independent channels. When “Bridge-
Mono” mode is selected, the amplifier bridges
the two output channels for twice the output
voltage.
Reset: A front-panel push button used to
reset the circuit breaker that protects the
power supply.
Sensitivity: A two-position switch located on
the back panel next to the Mode switch.
Switchable between 1.4 volts for full output
into an 8-ohm load (default setting), or a fixed
voltage gain of 26 dB. 0.775-volt sensitivity
available as a Service Option.
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.
Indicators
(all located on front panel)
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.
