HELIX NEXT V TWO

The perfect complement to powerful audio setups

The compact HELIX V TWO 2-channel amplifier uniquely combines audiophile sound demands with impressive performance. Its wide frequency response, excellent signal-to-noise ratio, and extremely low distortion ensure sound quality that will satisfy even the most discerning music lovers.
The bridgeable speaker outputs allow for flexible configuration and guarantee maximum power output – whether in mono mode for demanding subwoofers or as a high-resolution stereo amplifier for power-hungry speaker systems. Anyone looking for a powerhouse with audiophile DNA will find the perfect solution here.

Power meets audiophile performance

With a high signal-to-noise ratio of >109 dB, an extremely low total harmonic distortion of <0.004% THD+N, and a high damping factor, it effortlessly meets even the most demanding sonic requirements. The bridgeable speaker outputs allow maximum output power precisely where it's needed. This makes the V TWO the ideal choice for anyone who wants to combine uncompromising sound performance with a wide range of applications. Stereo performance for versatile speaker applications. In full-range stereo mode, the V TWO delivers more than enough power with 2 x 200 watts RMS at 4 ohms or 2 x 400 watts RMS at 2 ohms to confidently drive even demanding woofers or hybrid subwoofers, such as the COMPOSE i5 S200FM. Besides its powerful performance, it also impresses with its sonic precision: The wide frequency response and its audiophile qualities ensure that even the finest details are reproduced accurately and without distortion. Mono bridged operation for level-oriented subwoofer applications. In bridged mode, the V TWO delivers up to 800 watts RMS into 4 ohms – more than enough to drive even high-performance subwoofers with full dynamics and control. Particularly powerful DVC2 subwoofers (2 x 2 ohms) such as the models of the HELIX IMPACT Q-Series or two SVC2 subwoofers (1 x 2 ohms) connected in series from the HELIX IMPACT K-Series benefit from the high efficiency and excellent sound quality of this configuration. Thanks to the integrated mono mode, a single input signal is sufficient for operation – the perfect prerequisite for use with DSPs where the subwoofer channel is already summed. Full control – automatic or manual. The V TWO's new, innovative Amplifier Control Panel (ACP) offers intuitive and precise control of key amplifier functions – from automatic and manual gain adjustment and input mode to ground connection. A highlight is the Auto Gain Ranging (AGR) function: it automatically detects the output voltage of the connected signal source and precisely adjusts the gain to ensure optimal signal quality – quickly, reliably, and without clipping or unnecessary distortion. For those who prefer manual control, the input sensitivity can be configured in precise 0.5-volt increments between 0.5 and 8 volts. The integrated clipping indicator provides visual feedback at all times and enables precise adjustment.

Optimized for DSP-controlled sound concepts – pure, linear, lossless

The DirectDSP input is a wideband RCA input specifically designed for the outputs of modern standalone DSPs or DSP amplifiers. By eliminating the need for traditional crossovers, the signal remains linear and unaltered – for maximum transparency and fidelity. Ideally suited for DSP-based systems.

V-AMP Link – High-level connection, tailor-made for HELIX V amplifiers

The integrated V-AMP Link is a specially developed high-level input optimally matched to the speaker outputs of the HELIX V series. The key advantage: For system expansion, not only the RCA outputs of the V amplifier are available, but also its speaker outputs. This allows for the flexible integration of multiple V TWO amplifiers – for example, one for powerful woofers and another for the subwoofer. The V-AMP Link thus offers maximum flexibility when building complex and high-performance multi-channel setups.

Maximum efficiency – even under extreme conditions

Thanks to the intelligent power supply with an extended input voltage range of 6 to 18 V and sophisticated energy management, maximum system stability is guaranteed under all conditions – from classic combustion engines to fully electric vehicles.
Stabilized Output Power (SOP) technology ensures that the output power remains largely stable even with voltage fluctuations in the vehicle's electrical system. This guarantees consistent system performance even under real-world vehicle conditions.

Compact design with a clear design language

The V TWO features the typical HELIX design and integrates seamlessly into the V amplifier line. It has exactly the same dimensions as the V EIGHT – ideal for standardized installation concepts.

The very compact dimensions also allow for space-saving installation even in limited spaces.
The V TWO is therefore the perfect combination of power, efficiency, and form.

Special Features:

Class D amplifier technology

Digital amplifier concepts based on Class D technology offer significantly higher energy efficiency compared to classic Class AB amplifiers. The lower power consumption protects the battery and alternator and significantly reduces heat generation – ideal for use in modern vehicles. Thanks to continuous technological advancements, high-quality Class D amplifiers now achieve top-level performance in sound-relevant disciplines such as total harmonic distortion, bandwidth, and damping factor – and are therefore in no way inferior to classic analog designs. Bridgeable Speaker Outputs: The amplifier outputs of the V TWO are bridgeable – meaning that two channels can be combined to create a more powerful channel. This allows, for example, a single subwoofer to be driven with significantly more power. This flexibility opens up additional possibilities for system configuration and allows for targeted power bundling – without any sonic compromises. Innovative operating concept – the Amplifier Control Panel (ACP) The ACP enables convenient adjustment of key amplifier functions such as automatic gain configuration via proprietary AGR (Auto Gain Ranging), manual gain adjustment, input mode, and ground connection. Instead of conventional switches or knobs, the modern button control with LED indicators offers particularly intuitive operation and direct visual feedback on the device. Auto Gain Ranging – automatically perfectly adjusted The AGR function precisely adjusts the input gain in just a few seconds – quickly, reliably, and flawlessly. It automatically adapts the input sensitivity to the output voltage of the connected signal source, thus ensuring maximum sound quality. The Gain & The clipping indicator provides visual control at all times – ideal for professional results at the touch of a button.

V-AMP Link – designed for maximum power expansion

The V-AMP Link was specifically designed for connecting HELIX V-Series amplifiers and optimized for maximum signal quality – ideal when additional power is needed for subwoofers or powerful woofers.

Stabilized Output Power (SOP) – consistently powerful

Our SOP technology ensures stable output power even with fluctuating vehicle voltage – for example, during engine start-up or under high system load. Thanks to intelligent voltage management in the power supply, the amplifier power remains constant, and the sound is always dynamic and precise. Ideal especially for vehicles with dynamic alternator regulation and therefore fluctuating voltage conditions.

Start-Stop capability

The power supply in the HELIX V TWO amplifier ensures the internal voltage supply even during short-term drops down to 6 volts.

This ensures that the amplifier remains fully functional even when the engine is started.
