HELIX M One Monoblock with up to 600W

HELIX M ONE

Small, efficient, and unconditionally stable – the M ONE is a highly compact monoblock amplifier for subwoofer applications. Built using state-of-the-art Class D technology, this amplifier can even drive speakers with an impedance of just 1 ohm with complete control. Its current delivery capability makes it ideal for use with two 2-ohm subwoofers, where both voice coils are connected in parallel.

In addition, it boasts a comprehensive and exceptionally practical feature set that leaves nothing to be desired. And finally, thanks to its small dimensions, this mini powerhouse can always be installed in a suitable space.

Features

• Particularly compact Class D amplifier with a high output power of 600 watts RMS at 1 ohm - ideally suited for combination with all 2 x 2 ohm subwoofers in parallel operation
• Start-stop capability down to 6V supply voltage
• Intelligent high-level input with ADEP circuit (Advanced Diagnostics Error Protection) and automatic turn-on
• Integrated, active crossover with low-pass filter, bass boost, subsonic filter, and phase control
• Extremely load-stable power amplifier with high-current power transistors and 1-ohm stability
• Wired remote control for volume adjustment
• SMD technology (Surface Mounted Device) combines minimal space requirements with maximum reliability
• Exclusive, very Compact design with illuminated HELIX logo and low heat generation thanks to very high efficiency. Special Features: Intelligent High-Level Input. Modern, factory-installed car radios are becoming increasingly intelligent in their diagnostics of connected speakers. If an amplifier is connected to the radio instead, error messages often occur, sometimes even resulting in the loss of certain functions (such as the fader). The new ADEP circuit (Advanced Diagnostics Error Protection) prevents all these problems without unnecessarily stressing the radio's speaker outputs at high levels. Start-Stop Capability. The power supply in the HELIX M ONE amplifier ensures a stable internal voltage supply even during short-term drops down to 6 volts. This ensures that the HELIX M ONE remains fully functional even when the engine is started.
