The SALT-1 from Sundown Audio is a 1-channel amplifier that represents the peak performance 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 surface that signal higher processing quality, the heat sink is designed in striking titanium. Key features include the dual MOS-FET PWM power supply and digital coupling 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 placed great emphasis on details to provide a long-lasting, high-quality sound experience.
