Front Panel Controls
Level: A detented rotary level control for each
channel.

Back Panel Controls
Stereo/Mono: Two-position switch selects either
Stereo or Bridge-Mono operation.
Filter Switches (CE 4000 only),

volts for full output into an 8-ohm load (default set-
ting), or a fixed voltage gain of 26 dB.
Front Panel Indicators
Signal: Green LED for each channel flashes when
a very low-level signal (>–40 dBm) is at input. May
be used to troubleshoot cable runs.
Clip: Red LED for each channel turns on when
distortion becomes audible in the amplifier output.
Fault: Red LED flashes to signal fault condition.
Will also flash during normal start-up sequence.
Power: Green LED turns on when amplifier is on
and has power.
Input Connectors (standard module)
One Neutrik
®
Combo connector for each channel
(balanced 1/4-inch [6.35-mm] phone jack and 3-
pin female XLR connector, in parallel with a barrier
strip termination).
Output Connectors
CE 1000/CE 2000: Choice of 2 Neutrik Speakon
®
NL4MP (Models CE1000A or CE2000A), barrier
plus Speakon (CE1000AS1 or CE2000AS1), or 5-
way plus Speakon (CE1000AS2 orCE2000AS2);
CE 4000: 5-way plus Speakon.
Other Connectors
Fault Jack: RJ-11 jack allows remote monitoring
of amplifier Fault condition. An LED or other signal-
ing device (not supplied) may be used.
Protection
Protected against shorted, open or mismatched
loads; overloaded power supplies; excessive tem-
perature, chain destruction phenomena, input over-
load damage and high-frequency blowups. They
also protect loudspeakers from input/output DC,
large or dangerous DC offsets and turn-on/turn-off
transients.
Construction
Rugged steel chassis is coated with environmental-
ly friendly powder for long life and ease of mainte-
nance.
Cooling: Proportional speed fan.

Other Applications
W
ith their powerful, reliable performance, CE Series amps easily handle
2-ohm loads and are capable of chest-thumping lows. CE 4000
amplifiers feature Crown’s patented, award-winning BCA
®
(Class “I”) tech-
nology, and provide superior power output, increased efficiency, and leg-
endary Crown sound. CE 4000 amplifiers feature selectable, on-board
high- and low-pass filter sets, so you can easily add a sub-bass system.
With all models, optional SST modules provide features like crossovers
and summed bass output.
*Note: All measurements related 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 other other-
wise specified. Specifications for units supplied for units supplied outside the U.S.A.
may vary slightly at different AC voltages and frequencies.
