They have Crown's global regulated power supply, delivering full power regardless of AC mains voltage - from 120V to 277V and from 50Hz to 60Hz. Power Factor Correction (PFC) allows I-Tech to draw current from the mains more efficiently, providing more power from a single 20A breaker. The Class-I output and power supply promise the highest output voltage available, and a clearly audible difference through the speakers.
The Xs 1200 was also added to the Xs Series of power amplifiers, becoming the highest-powered model in the series. It provides 1,100W per channel into 4ohms and is designed for mobile DJs, musicians and regional tour companies.
