Helix M One Mono Subwoofer Amp 1 Channel Class D Amplifier up to 600w RMS 1 Ohm

HELIX M ONE

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.

Features

• 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 requirement with maximum reliability
• Exclusive, extremely compact and clean design with illuminated HELIX-logo and low heat dissipation thanks to extraordinary efficiency

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.
