Sundown Audio SALT-1

The SALT-1 from Sundown Audio is a 1-channel amplifier that represents the pinnacle of Korean Class-D amplifier technology. This series builds on 15 years of technological development to provide optimal performance at realistic operating voltages in the 12V range. With a weight and a surface that signals higher quality workmanship, the heat sink has an eye-catching titanium design. Standout features include dual MOS-FET PWM power supply and digital interfacing as a Class D mono block amplifier. Important protection mechanisms and a remote control for monitoring voltage, temperature and clipping complete the package. Developers have paid great attention to details to provide a long-lasting, high-quality sound experience.

• 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 spanning 15 years (the SAZ v.1, SAZ, v.2 and SCV series) to achieve even higher performance. Our customers have asked us for many years to produce amplifiers that deliver optimal performance at realistic operating voltages in the 12 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 simply a fan of sound quality, the SALT series will feel at home in your system. Each individual model has been designed with great attention to detail to ensure that they will put a smile on your face every time the music starts playing and that they will last for many years to come.
• Cosmetically, they differ greatly from our original design, which is an outward indicator of the improved performance level. The heatsink is the heaviest we've ever made, has the largest 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 displays, allowing you to easily monitor the vitals of your valuable audio system.
