HELIX M ONE

Features

• Particularly compact Class D amplifier with high output power of 600 watts RMS 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 (Advanced Diagnostics Error Protection) circuitry and automatic power-on
• Integrated, active crossover with low pass, bass boost, subsonic and phase
• Extremely load-stable power amplifier with high-current power transistors and 1 ohm stability
• Cable remote control for volume control
• 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 when it comes to diagnosing the connected speakers. If an amplifier is connected to the radio instead, there are usually error messages or even the loss of individual functions (such as faders). The new ADEP circuit (Advanced Diagnostics Error Protection) prevents all of these problems without unnecessarily loading the radio's speaker outputs at high levels.

Start-stop capability

The power supply in the HELIX M ONE amplifier ensures the internal power supply even in the event of short-term drops down to 6 volts. This ensures that the HELIX M ONE remains fully functional even when the engine is started.
