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 deliver optimum performance at realistic operating voltages in the 12V range. With a weight and finish that signal superior build quality, the heatsink features an eye-catching titanium design. Stand-out features include dual MOS-FET PWM power supply and digital coupling capability as a class D mono block amplifier. Important protection mechanisms and a remote control for monitoring voltage, temperature and clipping round off the package. Developers have paid great attention to detail in order to provide a long-lasting, high-quality sound experience.

• The Sundown Audio SALT amplifiers represent the pinnacle of Korean Class D amplifier technology. They stand on the shoulders of 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 been asking us for many years to produce amplifiers that deliver optimum performance at realistic operating voltages in the 12-volt range, not 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 quality sound, the SALT Series will feel right at home in your system. Each and every 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 an eye-catching 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 vital signs of your precious audio system.
