Helix M FOUR 4-channel Class D Amplifier

Despite its super compact dimensions on the other hand and thanks to the Class D design type, the M FOUR is highly efficient. 3 or 2 channel configurations are possible, which provide up to 2 x 200 Watts RMS of clean output power. The new ADEP circuit (Advanced Diagnostics Error Protection) avoids all these problems without unnecessarily loading the OE radio speaker outputs at high volumes. Start-Stop functionality. HELIX M FOUR's switched power supply ensures operation even if the battery voltage drops to 6 Volts during engine cranking.

M FOUR Features

  • Class D amplifier with compact footprint and high output power of 100 Watts RMS at 4 and 2 ohms
  • Start-Stop function up to 6V power supply voltage
  • Intelligent high level input with ADEP circuit (Advanced Diagnostics Error Protection) and Auto Turn-On function
  • Active and integrated crossover with high-pass, low-pass and band-pass
  • "Input mode" switch for flexible input signal routing
  • SMD (Surface Mounted Device) production technology combines minimal space required with maximum reliability
  • Exclusive design, extremely compact and clean with illuminated HELIX logo and low heat dissipation thanks to extraordinary efficiency
