Affordable Power in a Compact Design

       Small, efficient and uncompromisingly stable – the M ONE is a highly compact monoblock for subwoofer applications. Designed from latest Class D technology this tiny amp can easily control speakers with 1 Ohm impedance. Its current capability makes the M ONE a perfect partner for 2 x 2 Ohms subwoofers, where both voice coils are connected in parallel.

       In addition a comprehensive and stunningly practical feature set leaves nothing to be desired. Last but not least installation will be a no-brainer due to the minimal dimensions.

Smart highlevel input

The latest generation of OE car radios incorporates sophisticated possibilities of diagnosing the connected speakers. If a common amplifier will be hooked up failure messages and loss of specific features (e.g. fader function) quite often appear – but not with the M ONE.
The new ADEP circuit (Advanced Diagnostics Error Protection) avoids all these problems without loading the speaker outputs of the OE radio during high volumes unnecessarily.

Start-Stop capability

The switched power supply of the HELIX M ONE assures operation even if the battery’s voltage drops down to 6 Volts during engine crank.

  • Small footprint Class D amplifier with high output
    power of 600 Watts RMS @ 1 Ohm for easiest combination with all 2 x 2 Ohms subwoofers connected in parallel
  • Start-Stop capability down to 6V supply voltage
  • Smart highlevel input with ADEP circuit (Advanced Diagnostics Error Protection) and Auto Turn-On function
  • Integrated, active crossover with lowpass, bass boost, subsonic and phase control
  • Extremely stable output stage with high-current power transistors and 1 Ohm stability
  • Bass remote control for volume adjustment
  • SMD (Surface Mounted Device) manufacturing technology combines minimum space requirementwith maximum reliability
  • Exclusive, extremely compact and clean design with illuminated HELIX-logo and low heat dissipation thanks to extraordinary efficiency

FAQ

HELIX products purchased through ResoNix include a one-year warranty through us. Please contact us if you experience an issue with your product or need assistance with a warranty claim.

The best DSP depends on your vehicle, factory audio system, speaker configuration, and overall system goals. Contact the ResoNix team for a vehicle-specific recommendation before placing your order.

Yes. We offer educational resources for customers who would like to learn how to tune their own DSP. For those who prefer professional assistance, ResoNix also offers remote tuning services to help properly configure and optimize the system.

The correct connection method depends on your vehicle, head unit, and factory audio system. Contact the ResoNix technical support team for a vehicle-specific integration recommendation.

The correct version depends on whether your HELIX DSP uses an SCP (Smart Control Port) or a Control Input connection. Please refer to the official HELIX CONDUCTOR compatibility chart to identify the correct version for your processor.

The Control Input version can also be connected to newer devices with an SCP input using the optional SCP-to-Control Input adapter.

The output channels on HELIX V Series and P Series DSP amplifiers cannot be bridged. However, the output channels on the HELIX AMPLIFY 206 DSP can be configured for bridged operation.

Yes. A calibrated measurement microphone is required to complete the remote tuning process accurately. ResoNix offers a complete Measurement and DSP Tuning Kit with the equipment needed for your remote tuning session.
