With the SALT-400.2, Sundown Audio presents a pioneering 2-channel amplifier. This model represents the pinnacle of Korean Class-D amplifier technology and was developed from the rich heritage of three previous generations of high-quality Korean amplifiers. The SALT-400.2 is perfect for everyone, from world-class SPL competitors to passionate enthusiasts, and offers optimal performance at realistic operating voltages in the 12 range. With its striking titanium-colored heatsink, improved remote control and unique Low-Voltage Technology, this amplifier series sets new standards.

Characteristics

• The Sundown Audio SALT amplifiers represent the pinnacle of Korean Class-D amplifier technology. They stand on the shoulders of the three previous generations of Korean high-end amplifiers from 15 years ago (the SAZ v.1, SAZ, v.2 and SCV series) to achieve even higher performance. Our customers have been asking us for many years to produce amplifiers that deliver optimal performance at realistic operating voltages in the 12s range rather than 14+ volts. The SALT - Sundown Audio Low-Voltage Technology - series is our answer!
• Whether you're a world-class SPL competitor, a dedicated enthusiast, or just a fan of sound quality, the SALT range will feel right at home in your system. Each and every model has been designed with great attention to detail to ensure they'll put a smile on your face every time the music starts playing, and that they'll last for many years to come too.
• Cosmetically they are a big departure from our original design, which is an outward indicator of the improved performance level. The heatsink is the heaviest we have ever made, has the most surface area and is finished in a striking titanium color. These amplifiers look as good as they sound and once you hold one in your hands the build quality is obvious. The icing on the cake is the redesigned remote control with temperature, voltage and clipping indicators, allowing you to easily monitor the vitals of your precious audio system.
