Amplifiers

SALT Amplifiers

The SALT amplifiers are one of Sundown’s newer amplifier innovations. If you don’t know what SALT stands for, it means Sundown Audio Low Voltage Technology. This line of amplifiers replaced the SCV line because for so long, amplifiers have usually been rated at anywhere between 14.4v and 14.8v. The Sundown SALT amplifiers are rated differently, they do rated (and then some) at 12.8v. They are known to be one of the best half-bridge Korean amplifiers. Now that we know what the SALT amplifiers are, let’s take a look at what sizes they come in and what features and specifications each one has. To watch a tour of the Sundown SALT line, click here.
