Helix M FOUR - 24 Volt

HELIX M FOUR - 24 Volt Edition

If you want to give your front and rear speakers a real boost, then the M FOUR is exactly the right "tool" for the job. With a full 100 watts of continuous power per channel into 4 ohms as well as into 2 ohms, it really heats up the voice coils despite its super-compact dimensions. The amplifier itself stays cool thanks to highly efficient Class D technology. But even in 3-channel or 2-channel configurations, it really gets down to business with up to 2 x 200 watts RMS.

Thanks to its start-stop capability and the intelligent ADEP high-level input, the M FOUR - 24V Edition can cope with all the challenges that modern vehicles pose for the integration of an amplifier. And the perfect sound is also quickly found thanks to the integrated crossover and the extensive adjustment options.

Features

✓ Particularly compact Class D amplifier with high output power of 100 watts RMS at 4 and 2 ohms

✓ Start-stop capability down to 6V supply voltage

✓ Intelligent high-level input with ADEP circuit (Advanced Diagnostics Error Protection) and automatic switch-on

✓ Integrated, active crossover with high pass, low pass and band pass

✓ "Input Mode" switch for flexible distribution of the input signals

✓ SMD technology (Surface Mounted Device) combines minimum space requirement 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 with regard to the diagnosis of the connected speakers. If an amplifier is connected to the radio instead, this usually results in error messages or even the loss of individual functions (e.g. faders). The new ADEP circuit (Advanced Diagnostics Error Protection) prevents all these problems without unnecessarily overloading the radio's speaker outputs at high levels.

✓ Start-stop capability

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