Product Description

The L-450M is a 2-channel digital circuit processing power amplifier capable of amplifying weak electrical signals from the signal source to drive speakers and produce sound. With a maximum output power of up to 900W, the massive power output ensures the greatest power headroom, enabling 5S speakers to deliver superior sound quality. The L-450M power amplification circuit adopts a true Class I circuit design, providing more precise sound while maintaining substantial power headroom, allowing the speakers to perform at their best. A high-quality audio system relies heavily on the indispensable role of the amplifier.
