HELIX M FOUR - 24V Edition
If you want to really get your front and rear speakers going, then the M FOUR - 24V Edition is exactly the right "tool" for it.
With a whopping 100 watts of continuous power per channel at 4 ohms as well as at 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 handle all the challenges that modern vehicles pose for integrating an amplifier.
And the perfect sound is quickly found thanks to the integrated crossover and the extensive setting 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 12V supply voltage
- Intelligent high-level input with ADEP circuit (Advanced Diagnostics Error Protection) and automatic switching 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 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 loudspeakers. If an amplifier is connected to the radio instead, error messages usually occur, 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 loudspeaker outputs at high levels.
Start-stop capability
The power supply in the HELIX M FOUR - 24V Edition amplifier ensures the internal voltage supply even in the event of short-term drops of down to 12 volts. This ensures that the HELIX M FOUR - 24V Edition remains fully functional even when the engine is started.
