performance. The PowerLight 2.4

is rated at
1050 watts into 8 ohms, 1700 watts into 4 ohms,
and 2400 watts into 2 ohms, making it ideal for
powering subwoofers and high power, passive,
full-range speaker systems. A high-efficiency, 3­step output circuit reduces AC current draw and
improves performance with low impedance loads.
Outstanding audio performance and reliability,
networkability, and light weight make this
amplifier ideal for all critical sound system
applications.
