the XA Series takes advantage of the efficiency, low operating temperature and reduced THD of a Class D amplifier while still maintaining ultra-clear sound quality with maximum performance. This means Eclipse can offer a higher-powered amplifier that requires less space, produces less heat, offers higher sound quality and is more efficient other amplifiers. Top mounted controls allow easy access to all settings for fine-tuning and tweaking. A clipping indicator LED is mounted on the top to assist in amplifier tuning. No more guesswork when setting your gain—the amp tells you when it’s just right! The XA series features a fully variable low-pass and high-pass crossovers from 30-500 HZ, and offers 18 dB slopes for accurate frequency cut-off.
