Sundown Audio Salt Series Monoblock Digital Class-D Amplifier (Salt-8 8000W Rms)

  • Power – 500 Watts Max x 2 @2-Ohms, 250 Watts Max x 2 @4-Ohms, 1000 Watts Max x 1 Bridged @4 Ohms.
  • Full Range – With a Full Range amplifier you not only have the option to run your speakers, but also your subwoofers.
  • Class A/B Topology – Class ‘A’ amplifiers have enormous amount of current flowing through its output transistors with no audio signal. Class ‘B’ amplifiers have no current flowing through its outputs with no audio signal.
  • Mosfet Power Supply – A MOSFET is an electrical switch that allows the flow of electrical current. It controls the output voltage and current precisely by removing the output current sensing loss & eliminating all secondary feedback circuitry.
  • Variable Gain Control – The gain control is not for adjusting volume. It simply adjusts the amount of signal that is coming from your receiver and going to your amplifier.
