Xs4300 (120 V, 60 Hz model)

The Crown® Xs4300 power amplifi er shall be a solid-state four-channel
model employing Class B output circuitry.

The amplifi er shall include protection from shorted, open and mismatched
loads, general overheating, DC, high-frequency overloads, under/over volt­age, and internal faults.

The front-panel controls shall be a power switch and a gray rotary level
control (one per channel).

The recommended load impedance shall be 4 to 8 ohms.
Rear-mounted input connectors shall be one per channel XLR-1/4" combo

connector including a 3-pin female XLR connector and TRS 1/4" phone
jack. Rear-mounted output connectors shall be one pair per channel bind­ing posts.

Front panel indicators shall include two yellow Bridge-Mode Indicators (one
for channels 1 and 2, one for channels 3 and 4) that illuminate when the
Mode Switch is set to the “Bridge” position, a green Signal Indicator (one
per channel) that illuminates when the channel’s input signal level is above
–40 dBu, a red Clip Indicator (one per channel) that illuminates when
the channel’s output signal is being overdriven, two red Temp Indicators
(one for channels 1 and 2, one for channels 3 and 4) that illuminate
when channel(s) are in thermal protect mode, a red Fault Indicator that
illuminates when the amplifi er is in protect mode and also briefl y during
normal power-up when amplifi er is fi rst switched on, a yellow Power
Indicator that indicates amplifi er has been turned on, and a red AC Mains
Indicator that illuminates when AC power is present at the power cord.

The power amplifi er shall meet or exceed the following performance crite­ria. Input sensitivity for rated output: 1.4V. Rated output with both channels
driven in Dual mode with 0.15% THD (1 kHz): 200 watts per channel into
8 ohms and 300 watts per channel into 4 ohms. Bridge-mono output power
with 0.15% THD (1 kHz): 700 watts into 8 ohms. Frequency Response at
1 watt, 22 Hz to 22 kHz: ± 1 dB. Signal to Noise Ratio below rated power:
> 107 dB A-weighted. Total Harmonic Distortion at full rated power from 20
Hz to 20 kHz: < 0.5%. Damping Factor: > 200 from 10 to 100 Hz. Crosstalk
(below rated power): > 57 dB at 1kHz and > 40 dB at 20 kHz. DC Output
Offset (shorted input): < ± 75 mV. Input Impedance (nominal): 20 kilohms
balanced, 10 kilohms unbalanced.

The amplifi er chassis shall be constructed of steel with a durable black
fi nish and shall be designed for forced-air ventilation from the front panel
to the back panel.

The dimensions of the amplifi er shall allow for 19 inch (48.3 cm) EIA
standard (RS-310-B) rack mounting. The amplifi er shall be 3.5 inches
(8.9 cm) tall, and 17.14 inches (43.5 cm) deep behind the rack-mounting
surface.

The amplifi er shall weigh 28 lb 14 oz (13.1 kg).
The amplifi er shall be designated the Crown Xs4300.
