Description
HELIX M FOUR - 24V Edition
If you like to rev up your front and rear speakers, the M FOUR - 24V Edition will be exactly the right "tool" to do so. With generously 100 Watts RMS per channel into both 4 Ohms and 2 Ohms load this amp will heat up your voice coils in no time despite its super-compact dimensions. On the other hand the M FOUR - 24V Edition stays totally cool thanks to the highly efficient Class D design topology. 3-channel or 2-channel configurations are possible as well, delivering up to 2 x 200 Watts RMS of clean and undistorted output power.
Needless to say that the M FOUR - 24V Edition is equipped with a bunch of intelligent attributes like "start-stop capability" and our proprietary "ADEP" highlevel input so that it easily deals with all installation challenges of modern cars. Finally the extensive audio features will offer a sound quality at its best.
Features
- Small footprint Class D amplifier with high output power of 100 Watts RMS @ 4 and 2 Ohms load
- Start-Stop capability down to 12V supply voltage
- Smart highlevel input with ADEP circuit (Advanced Diagnostics Error Protection) and Auto Turn-On function
- Integrated, active crossover with highpass, lowpass and bandpass
- “Input mode” switch for flexible input signal routing
- SMD (Surface Mounted Device) manufacturing technology combines minimum space requirement with maximum reliability
- Exclusive, extremely compact and clean design with illuminated HELIX-logo and low heat dissipation thanks to extraordinary efficiency
Special features:
Smart highlevel input
The latest generation of OE car radios incorporates sophisticated possibilities of diagnosing the connected speakers. If a common amplifier will be hooked up failure messages and loss of specific features (e.g. fader function) quite often appear - but not with the M FOUR - 24V Edition.
The new ADEP circuit (Advanced Diagnostics Error Protection) avoids all these problems without loading the speaker outputs of the OE radio during high volumes unnecessarily.
Start-Stop capability
The switched power supply of the HELIX M FOUR - 24V Edition assures operation even if the battery’s voltage drops down to 12 Volts during engine crank.
