Ultra Ul400M Linear Marine Audio Amplifier - Unparalleled Sonic Performance for Marine Applications

The Ultra Ul400M Linear Marine Audio Amplifier, model number Ul400, is a high-performance, marine-grade audio amplifier designed to deliver exceptional sound quality in harsh marine environments. This amplifier is engineered to meet the unique demands of marine audio, ensuring reliable, distortion-free audio even in the face of extreme temperatures, humidity, and saltwater corrosion.

The Ul400 is a 400-watt, four-channel linear amplifier, meaning it can power four speakers or two pairs of speakers with a maximum power output of 100 watts per channel (RMS). Each channel is individually bridged, allowing for flexibility in system configuration. The amplifier employs a Class AB topology, known for its ability to produce clean, powerful audio while minimizing heat production and distortion.

This marine-grade amplifier features gold-plated screw terminals for secure, corrosion-resistant speaker connections. It also boasts a waterproof, UV-resistant enclosure to protect internal components from the elements. The Ul400 is equipped with an LED power indicator for easy system monitoring and features a variable low-pass filter (LPF) on each channel to help ensure optimal bass response from your speakers.

Installation and adjustment are made simple with the Ultra Ul400M Linear Marine Audio Amplifier's user-friendly controls. The amplifier comes with a detachable, auto-ranging 100-240V AC power supply for global compatibility. With its robust construction, powerful output, and marine-specific features, the Ultra Ul400M Linear Marine Audio Amplifier is the ideal choice for boat owners and marine audio enthusiasts who demand superior sound quality and reliability.
