CE 2000
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
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.

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
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.

device (not supplied) may be used.
(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.

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 nor-
mal working limits.
3. If the transformer thermal protection circuit is ac-
4. If amplifier output wires develop a short-circuit.
5. Should the amplifier output stage become non-
This circuit may be monitored remotely by
plugging a simple switching circuit using an

panel RJ-11 (Fault) jack. Under some condi-
tions, the output of the amplifier will be

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 cov-
ered 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 219-294-8200.
