CE 1000 (60-Hz models)

The Crown® CE 1000 power ampliﬁer shall be a solid-state two-channel model.

The outputs shall be switchable as stereo or bridged-mono modes of operation. The bridged-mono mode shall bridge the outputs to provide increased output voltage.

The output impedance of each channel shall be less than 10 milliohms in series with less than 2 microhenries in stereo mode.

The ampliﬁer shall contain controlled slew-rate voltage circuitry to protect it against radio frequency interference burnouts. It shall also be protected from current overload at its output stage. The slew rate of the ampliﬁer shall be greater than 30 volts per microsecond in stereo mode.

The ampliﬁer shall temporarily go into a stand-by mode if its power trans- former becomes excessively hot and shall automatically resume normal operation once it has cooled to a safe operating temperature.

Front-panel controls shall include an enable on/off switch, a detented input level control for each channel and a reset switch.

Rear-mounted controls shall include an Input Sensitivity switch for each channel to select between 1.4 V or a ﬁxed voltage gain of 26 dB for full rated output, a Mode switch to select whether the amp is in Bridge Mono mode or Stereo mode, and an RJ-11 Fault output connector.

Front panel indicators shall include a green Power indicator to show the ampliﬁer has power, a red Clip indicator for each channel which shall turn on when distortion of any type becomes audible in the ampliﬁer output, a red Fault indicator for each channel which will blink under 5 conditions:

1)When the ampliﬁer is ﬁrst turned 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 circuit is activated. 4) If the ampliﬁer wires develop a short circuit, and 5) should the ampliﬁer output stage become non-operational. There is also a green Signal indicator for each channel which shall ﬂash dimly when a low-level signal (> –40 dBm) is present at the input of the ampliﬁer.

The power ampliﬁer shall meet or exceed the following performance criteria. Input sensitivity for rated output: 26 dB voltage gain (unbalanced). Rated FTC output in stereo mode with less than 0.1% THD: 275 watts per channel (1 kHz) into 8 ohms. Hum and noise: at least 105 dB (A weighted) below full rated output power. Frequency response: 20 Hz to 20 kHz, 0.1 dB at 1 watt into 8 ohms per channel in stereo mode. Damping factor: greater than 400 from 10 to 400 Hz into 8 ohms. Phase response: 15 from 20 Hz to 20 kHz at 1 watt.

The ampliﬁer shall be safe when driving any kind of load—even highly reactive ones.

The power requirements shall be 120 VAC at 60 Hz. At idle, the ampliﬁer shall draw 90 watts or less.

The ampliﬁer shall have a rugged steel chassis coated with environmentally friendly powder.

The dimensions of the ampliﬁer shall allow for 19 inch (48.3 cm) EIA standard (RS-310-B) rack mounting. The ampliﬁer shall be 5.25 inches (13.34 cm) tall and 12.25 inches (31.11 cm) deep behind the rack-mount- ing surface.

The ampliﬁer shall weigh 32.6 pounds (14.79 kg) and shall have a center of gravity approximately 6 inches (15.2 cm) behind the front panel.

The ampliﬁer shall be designated the Crown CE 1000.

CE 1000 A. & E specifications

The Crown Audio CE 1000 A & E is a powerful and versatile amplifier designed for professional audio applications, making it a choice for both live sound reinforcement and permanent installations. With its robust build quality and advanced technologies, the CE 1000 A & E stands out in the competitive field of audio amplification.

One of the main features of the CE 1000 A & E is its high power output. The amplifier delivers 1000 watts per channel at 4 ohms, and 500 watts per channel at 8 ohms, providing users with ample power to drive various passive loudspeakers. This makes it suitable for a wide range of contexts, from energetic concerts to intimate events and permanent fixture setups.

Another notable characteristic of this amplifier is its lightweight design. Weighing in at just over 15 pounds, the CE 1000 A & E is constructed with a switch-mode power supply and Class H amplifier topology, which not only reduces weight but also enhances efficiency. This means the amplifier can maintain high levels of performance without generating excessive heat, ensuring reliability during prolonged use.

The CE 1000 A & E features Crown's patented Output Voltage Limiting technology, which automatically reduces distortion and protects connected speakers from damage during high-demand audio moments. This is particularly beneficial in live settings where sudden bursts of sound may occur. The amplifier also incorporates an advanced protection circuitry that safeguards against over-temperature, short circuits, and overload, providing peace of mind for audio professionals.

Audio fidelity is another hallmark of the CE 1000 A & E. It features a wide frequency response of 20 Hz to 20 kHz, ensuring that both the low-end punch and high-frequency clarity are delivered with precision. Additionally, the amplifier is capable of handling dynamic audio signals with high transient response, making it ideal for various sound genres.

For user convenience, the CE 1000 A & E includes a comprehensive front-panel with LED indicators that provide real-time feedback on power, signal presence, and protection status. Connections are simplified with dual binding post outputs for flexible setup options, as well as XLR inputs for easy integration with professional audio systems.

In summary, the Crown Audio CE 1000 A & E combines power, efficiency, and advanced features in a compact package. With its reliable performance and rich audio fidelity, this amplifier is an excellent choice for audio engineers and enthusiasts who demand quality and durability in their sound reinforcement solutions.
