Helix Next V Two - 2 Channel Amplifier

The HELIX V TWO 2-channel amplifier uniquely combines audiophile sound aspirations with impressive output performance. Its wideband frequency response, excellent signal-to-noise ratio and ultra-low distortion ensure a sound quality that will satisfy even the most demanding music enthusiasts.

Thanks to its bridgeable speaker outputs, the amplifier offers flexible configuration options and delivers maximum output – whether in mono mode to drive high-performance subwoofers or in stereo configuration for powerful speaker systems. If you're looking for a compact powerhouse with audiophile DNA, here comes your ideal solution.

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, the V TWO effortlessly meets even the most demanding sonic expectations. Its bridgeable speaker outputs ensure maximum output power exactly where it’s needed. This makes the V TWO the ideal choice for anyone seeking uncompromising sound performance combined with exceptional versatility.

Stereo performance for versatile speaker applications

In fullrange stereo operation, the V TWO delivers 2 x 200 Watts RMS at 4 Ohms and 2 x 400 Watts RMS at 2 Ohms – more than enough power to drive even demanding midbass speakers or hybrid subwoofers like the COMPOSE i5 S200FM with authority.
In addition to its powerful output, it also impresses with tonal precision: the wide frequency response and audiophile-grade characteristics ensure that even the finest details are reproduced with accuracy and uncolored.

Mono bridged operation for output-focused subwoofer applications

In bridged mode, the V TWO delivers up to 800 Watts RMS at 4 Ohms – more than enough to drive even high-performance subwoofers with full dynamics and control. Powerful DVC2 subwoofers (2 x 2 Ohms) like those from the HELIX IMPACT Q series or two series-wired SVC2 subwoofers (1 x 2 Ohms) from the HELIX IMPACT K series, benefit from the high efficiency and outstanding sound quality of this configuration. Thanks to the integrated mono mode, a single input signal is sufficient for full operation – the perfect setup for use with DSPs that already provide a summed subwoofer output.

Full control – automatic or manual

The V TWO features the all-new, innovative Amplifier Control Panel (ACP), offering intuitive and precise control of all key amplifier functions – from automatic and manual gain adjustment to input mode and input reference configuration.

A standout highlight is the Auto Gain Ranging (AGR) function: It automatically detects the output voltage of the connected signal source and adjusts the gain accordingly for optimum signal quality – fast, reliably, and without clipping or unwanted distortion.
Prefer manual tuning? The input sensitivity can also be fine-tuned in precise 0.5 V steps between 0.5 and 8 Volts. An integrated clipping indicator provides constant visual feedback, allowing for accurate adjustment.

Optimized for DSP-based system designs – pure, linear, lossless

The DirectDSP input is a wideband RCA input specifically tailored to the outputs of modern standalone DSPs or DSP amplifiers. By omitting traditional crossover circuits, the signal path remains linear and unaltered – ensuring maximum transparency and sonic fidelity. Perfectly suited for DSP-driven audio setups.

V-AMP Link – Highlevel input tailored for HELIX V amplifiers

The integrated V-AMP Link is a specially developed highlevel input, perfectly matched to the speaker outputs of the HELIX V series. The key advantage: in addition to the RCA outputs, the speaker outputs of the V amplifier can also be used for system expansion. This allows multiple V TWO amps to be integrated with ease – for example, one for powerful midbass drivers and another for the subwoofer. The result is maximum flexibility when building complex, high-performance multi-channel setups.

Maximum efficiency – even under extreme conditions

Thanks to its intelligent power supply with an extended input voltage range from 6 to 18 V and advanced energy management, maximum system stability is ensured under all conditions – from conventional combustion engines to fully electric vehicles. 
In addition, the Stabilized Output Power (SOP) technology maintains consistent output levels even during voltage fluctuations in the vehicle’s electrical system. This guarantees steady system performance under real-world automotive conditions.

Compact design with a clear visual identity

The V TWO features the signature HELIX design and visually integrates seamlessly into the V amplifier series. It shares the same dimensions as the V EIGHT, making it ideal for uniform installation concepts. Its highly compact size also enables space-saving integration, even in limited installation environments. The V TWO is the perfect fusion of power, efficiency, and form.
