CROWN XLi 1500 - Two-channel power amplifier, 450W @ 4Ω

CROWN XLi 1500 – Two-channel power amplifier, 450 W @ 4 Ω

The CROWN XLi 1500 is a professional 2U rackmount amplifier delivering 450W continuous per channel into 4Ω and driving 2Ω, 8Ω, and bridged mono to 8Ω loads for a total of 900W. Its Class AB circuitry delivers warm, detailed sound ideal for portable and fixed PA reinforcement systems. Featuring electronically balanced RCA and XLR inputs, Speakon® and screw-type outputs, and a forced cooling system with a variable-speed fan that prevents heat build-up without generating excessive noise. With stereo, parallel, and bridged-mono operating modes and selectable input sensitivity (0.775V or 1.4V), the XLi 1500 combines power, flexibility, and reliability for musicians, DJs, houses of worship, and entertainment venues.
