Crown Audio XLi 3500 Two-channel 1350W Power Amplifier

Crown Audio XLi 3500 Two-Channel 1350W Power Amplifier

The Crown Audio XLi 3500 is a workhorse amplifier built on six decades of Crown's amplifier engineering expertise. This unit delivers 1350W per channel at 4 ohms with the reliability and thermal management needed for sustained professional use in live sound, installed systems, and touring applications. The compact 3.5-inch rack-mount form factor houses serious power without requiring dedicated infrastructure.

Power & Connectivity

Output reaches 1350W at 4 ohms, 1000W at 8 ohms, or 2700W in bridged-mono mode, giving you flexible deployment options for different speaker configurations. Both RCA and XLR inputs accommodate various source devices, while Speakon and binding post outputs ensure compatibility with professional and consumer speaker systems alike.

Audio Performance & Design

The amplifier maintains frequency response of 20Hz–20kHz (+0/−1dB) with THD below 0.5% and signal-to-noise ratio exceeding 100dB (A-weighted), delivering clean, detailed amplification across the audible spectrum. Forced-air cooling prevents thermal buildup during extended operation, while integrated protection circuitry guards against shorts, no-load conditions, RF interference, and power-on transients.
