<p>HELIX M ONE X – 24V Edition<br>Small, efficient and uncompromisingly stable – the M ONE X – 24V Edition is a highly compact monoblock for subwoofer applications. Designed from latest Class D technology this tiny amp can easily control speakers with 1 Ohm impedance. Its current capability makes the M ONE X – 24V Edition a perfect partner for 2 x 2 Ohms subwoofers, where both voice coils are connected in parallel. And for even more output power, two M ONE X – 24V Edition amplifiers can be combined to one single powerhouse – thanks to the TwinPower Link.<br>In addition a comprehensive and stunningly practical feature set leaves nothing to be desired. Last but not least installation will be a no-brainer due to the minimal dimensions.<br><br>Features<br>Small footprint Class D amplifier with up to 1,180 Watts RMS output power @ 1 Ohm for easiest combination with all 2 x 2 Ohms subwoofers connected in parallel<br>Start-Stop capability down to 12V supply voltage<br>Smart highlevel input with ADEP circuit and Auto Turn-On function<br>Integrated, active crossover with lowpass, bass boost, subsonic and phase control<br>TwinPower Link for connecting two amplifiers in bridged mode<br>Bass remote control for volume adjustment<br>Low heat dissipation thanks to extraordinary efficiency<br>Special features<br>Smart highlevel input<br>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 ONE X – 24V Edition.<br>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.<br><br>Start-Stop capability<br>The switched power supply of the HELIX M ONE X – 24V Edition assures operation even if the battery’s voltage drops down to 12 Volts during engine crank.</p>
