CROWN XLi 3500 - Two-Channel Power Amplifier, 1350W @ 4Ω

CROWN XLi 3500 – Two-channel power amplifier, 1,350 W @ 4 Ω

The CROWN XLi 3500 combines professional power , reliability , and versatility in a 2U chassis optimized for touring, studio, or fixed installation. With 1,350W per channel into 4Ω and 1,000W into 8Ω , plus 2,700W in bridged mode , it delivers headroom and control in any sound system. Class AB amplification technology ensures a warm, accurate tone, while forced cooling with a variable-speed fan prevents overheating without generating excessive noise. Balanced RCA and XLR inputs, Speakon® and screw-terminal outputs, plus mode switching (stereo/parallel/bridge-mono) and selectable sensitivity (0.775V/1.4V) make it ideal for musicians, DJs, houses of worship, and hospitality venues looking for rugged, easy-to-use, and integrable equipment.

Frequently Asked Questions

• Can it be bridged with 4 Ω speakers? Yes; activate bridge mode to combine both channels and get 2,700 W at 8 Ω.
• How do I prevent the "thump" when turning on? The protection circuit integrates signal delay and power-on/power-off bump suppression.
• What sensitivity should I choose? Use 0.775 V for professional line signals, 1.4 V for consumer or DJ consoles.
