Architectural & Engineering Speciﬁcations

Crown® XLS 802

The power ampliﬁer shall be a solid-state two-channel model.

The ampliﬁer shall provide extensive protection and diagnostic capabili- ties, including output current limiting, DC protection, circuit breaker, and thermal protection.

The front-panel controls shall be two black detented level controls (one for each channel) and a power switch. The rear-panel controls shall be a circuit breaker reset switch and a Dual/Bridge-Mono mode switch.

Front-mounted indicators shall be the following: Signal Presence Indica-

tors: Two green LEDs, one for each channel, illuminate when the channel’s

input signal exceeds –40 dBu. Clip Indicators: Two red LEDs, one for each channel, illuminate when the channel’s output is being overdriven. Power Indicator: Blue LED indicates ampliﬁer has been turned on and AC power is available. Fault Indicator: Two red LEDs illuminate when ampliﬁer is in protect mode. Also illuminates brieﬂy during normal power-up when ampliﬁer is ﬁrst switched on.

The recommended load impedance shall be 4 to 8 ohms per channel in Stereo, and 8 ohms in Bridge Mono.

The rear-mounted output connectors shall be two 4-pole Speakon® con- nectors (one per channel) and a pair of binding posts per channel. Rear- mounted input connectors shall be 3-pin balanced XLR connectors.

The power ampliﬁer shall meet or exceed the following performance criteria: Sensitivity for full rated power at 4 ohms: 1.25 V. Rated output with both channels driven with 0.5% THD (at 1 kHz) in Dual mode: 800 watts per channel into 4 ohms and 500 watts per channel into 8 ohms. Rated output with 0.5% THD (at 1 kHz) in Bridge-Mono mode: 1,600 watts into 8 ohms. Frequency Response at 1 watt, 22 Hz to 20 kHz: +0 dB, –1 dB. Signal to Noise Ratio below rated power (20 Hz to 20 kHz, inputs terminated): greater than 100 dB A-weighted. Total Harmonic Distortion at full rated power, 1 kHz: less than 0.5%. Intermodulation Distortion (60 Hz and 7 kHz at 4:1, from full rated output to –40 dB: less than 0.3%. Damping Factor (8 ohms): greater than 200 from 10 to 400 Hz. Crosstalk (below rated power, –75 dB at 1 kHz, –50 dB at 20 kHz. Input Impedance (nominal): 20 kilohms balanced, 10 kilohms unbalanced. AC Line Voltages and Frequencies Available (±10%): 120 VAC 60Hz, 100 VAC 50/60 Hz, 220 VAC 50 Hz, 230-240 VAC 50 Hz.

The ampliﬁer chassis shall be constructed of steel with a durable black ﬁnish and shall be designed for ﬂow-through ventilation from the front panel to the back panel. Internal heat sinks with forced-air cooling shall provide rapid, uniform heat dissipation.

The dimensions of the ampliﬁer shall allow for 19 inch (48.3 cm) EIA standard (RS-310-B) rack mounting. The ampliﬁer shall be 3.5 inches (8.9 cm) tall, and 15.2 inches (38.6 cm) deep.

The ampliﬁer shall weigh 35.5 pounds (16.1 kg).

The ampliﬁer shall be designated the Crown XLS 802.
