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.
