Specifications
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 otherwise specified.
Specifications for units supplied for units supplied outside the U.S.A. may vary slightly at dif-
ferent AC voltages and frequencies.
Performance
Frequency Response (at 1 watt): ±0.2 dB from 20 Hz to 25 kHz.
Phase Response (at 1 watt) 20 Hz to 20 kHz: ±15 degrees.
Signal to Noise Ratio (below rated power), 20 Hz to 20 kHz: >100 dB
Total Harmonic Distortion (THD) at rated power from 20 Hz to 20 kHz:
0.5% or less.
Intermodulation Distortion (IMD) (60 Hz and 7 kHz at 4:1)
from 163 millwatts to full bandwidth power: < 0.1%.
Damping Factor from 10 Hz to 400 Hz: Greater than 400.
Crosstalk, below rated power, 20 Hz to 20 kHz: >55 dB.
Common Mode Rejection (CMR) 20 Hz to 1 kHz: > 70 dB.
DC Output Offset (Shorted Input): ±10 mV.
Power
Load Impedance: Safe with all types of loads. CE-1000 is rated for 2, 4
and 8 ohms in Stereo mode; 4 and 8 ohms in Bridge-Mono mode.
CE-2000TX is rated for 4 and 8 ohms in Stereo mode; 8 ohms in
Bridge-Mono mode.
Voltage Gain to 1-kHz, 8-ohm rated output:
CE 1000: 30.5 dB at 1.4-volt sensitivity; 26 dB gain at 2.34-volt sensi-
tivity.
CE 2000TX: 32.1 dB at 1.4-volt sensitivity; 26 dB at 2.83-volt sensitiv-
ity.
Required AC Mains: 50/60 Hz,100-240 VAC (±10%).
Power Draw At Idle: 90 watts.
Controls & 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. Selects Stereo or
Bridge-Mono operation.
Sensitivity:
Two-position switch: 1.4 volts for full output into an 8-ohm load
(default setting), or a fixed voltage gain of 26 dB.
Fault Jack: RJ11 jack allows remote monitoring of amplifier Fault condi-
tion. An LED or other signaling device (not supplied) may be used.
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.
Reset: Front-panel switch resets the power circuit breaker.
Input/Output
Input Connector (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 termina-
tion).
Input Stage: Input is electronically balanced and employs precision 1%
resistors.
Input Impedance: Nominally 20 k ohms, balanced. Nominally 10 k ohms,
unbalanced.
Input Sensitivity: 1.4 volts for standard 1-kHz power, or fixed 26-dB gain.
0.775-volt sensitivity is available as a Service Option.
Output
Output Connectors: Choice of 2 Neutrik Speakon
®
NL4MP (Models
CE1000A or CE2TX000A001), barrier plus Speakon (CE1000AS1 or
CE2TX000A002), or 5-way plus Speakon (CE1000AS2 or
CE2TX000Z003).
Output Signal: Stereo: Unbalanced, two-channel; Bridge-Mono: Balanced, sin-
gle-channel. Channel 1 controls are active; Channel 2 should be turned down.
Protection
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 transients.
Construction
Rugged steel chassis is coated with environmentally friendly powder
for long life and ease of maintenance.
Cooling: Proportional speed fan.
Dimensions: EIA Standard 19-inch rack mount width (EIA RS-310-B),
5.25-inch (13.34-cm) height and 12.25-inch (31.11-cm) depth behind
front mounting surface.
Weight:
CE 1000: 32.6 pounds (14.79 kg).
CE 2000TX: 40.3 pounds (18.28 kg).
For shipping weight, add 6 pounds (2.7 kg).
With their powerful, reliable performance, the CE-1000 and
CE-2000TX are capable of chest-thumping lows. The CE-1000
can easily handle 2-ohm loads. Optional SST modules provide
features like processing for JBL ScreenArray™ cinema speak-
er systems. Three types of output connectors are available.
Accessories: CE handles, CE-S1 Speakon-to-barrier output,
CE-S2 Speakon-to-5-way output, CEAS1 barrier block output,
CEAS2 5-way output.
