Helix M FOUR 24V

INFORMACIJA

HELIX M FOUR - 24V Edition
If you want to boost the sound of your front and rear speakers, the M FOUR - 24V Edition is exactly the "tool" you need. With a generous 100 W RMS per channel into both 4 Ω and 2 Ω loads, this amplifier will quickly heat up your voice coils despite its super-compact dimensions. On the other hand, the M FOUR - 24V Edition remains completely cool, thanks to its highly efficient Class D design topology. 3-channel or 2-channel configurations are possible, providing up to 2 x 200 W RMS of clean and undistorted output power.

Needless to say, the M FOUR - 24V Edition is equipped with many smart features, such as the "start-stop" function and our proprietary "ADEP" high-level input, making it easily cope with all installation challenges of modern cars. Finally, a wide range of audio features will ensure the best sound quality.

Features
Small footprint Class D amplifier with high output power of 100 W RMS @ 4 and 2 Ω load
"Start-Stop" function, operating down to 12V supply voltage
Smart high-level input with ADEP circuit (Advanced Diagnostics Error Protection) and automatic turn-on function
Integrated active crossover with high-pass, low-pass, and band-pass filters
"Input mode" switch for flexible input signal routing
SMD (surface mount device) manufacturing technology combines minimal space requirement with maximum reliability
Exclusive, ultra-compact and clean design with illuminated HELIX logo and low heat dissipation, thanks to extraordinary efficiency
Special features:
Smart high-level input
The latest generation of OE car radios includes sophisticated diagnostics for connected speakers. If a conventional amplifier is connected, error messages often appear and certain functions are lost (e.g., fader function) - but not with the M FOUR - 24V Edition.
The new ADEP circuit (Advanced Diagnostics Error Protection) avoids all these problems, without loading the OE radio's speaker outputs at high volumes.
