  • 4-Channel Class SQ (Class A/B) Amplifier
  • RMS Power Output:
    • 50W x 4 @ 2 ohms

  • Variable electronic crossovers allow for complete control of the sound
  • FLUID-FETS are painstakingly selected for their ability to efficiently produce power and mimic the sound quality of the highest end home amplifiers.
