HELIX M One X Monoblock with up to 1000W

Small, efficient, and unconditionally stable – the M ONE X is a highly compact monoblock amplifier for subwoofer applications. Built with state-of-the-art Class D technology, this amplifier can even handle 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. And for even more concentrated power, two M ONE X amplifiers can be linked together to create a powerful amplifier thanks to the TwinPower Link. 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 space.

Features

• Particularly compact Class D amplifier with up to 1,180 watts RMS maximum power at 1 ohm – ideal 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 and automatic turn-on
• Integrated, active crossover with low-pass filter, bass boost, subsonic filter, and phase control
• TwinPower Link for operating two amplifiers in bridged mode
• Wired remote control for volume adjustment
• Low heat generation thanks to very high efficiency

Special Features:

Intelligent High-level input

Modern, factory-installed car radios are becoming increasingly intelligent in diagnosing the 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 X amplifier ensures a stable internal voltage supply even during brief drops down to 6 volts.

This ensures that the HELIX M ONE X remains fully functional even when the engine is started.
