HELIX M FOUR
If you want to really get your front and rear speakers going, then the M FOUR is exactly the right tool for the job. With a hefty 100 watts of continuous power per channel at both 4 ohms and 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 it also delivers serious power in 3-channel or 2-channel configurations with up to 2 x 200 watts RMS.
Thanks to its start-stop capability and intelligent ADEP high-level input, the M FOUR easily handles all the challenges that modern vehicles present when integrating an amplifier. And the perfect sound is quickly achieved thanks to the integrated crossover and extensive adjustment options.
Features
- Especially 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 turn-on
- Integrated, active crossover with high-pass, low-pass, and band-pass filters
- "Input Mode" switch for flexible distribution of 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 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 FOUR amplifier ensures a stable internal voltage supply even during brief voltage drops down to 6 volts. This ensures that the HELIX M FOUR remains fully functional even when the engine is started.
