Sundown Audio SALT-1.5

The SALT-1.5 from Sundown Audio is a 1-channel amplifier characterized by its innovative Korean Class D technology. With 15 years of development, it offers optimum performance with realistic operating voltages in the 12V range. Special features include the dual MOS-FET PWM power supply and the option of digital coupling as a class D mono block amplifier. The amplifier impresses with an eye-catching titanium design and a robust heat sink, which underlines the high-quality workmanship. A wired remote control allows monitoring of voltage, temperature and clipping, while comprehensive protection mechanisms ensure a long-lasting sound experience.

Properties 

• 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 amps 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.
