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.
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.
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.
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.
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.
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.
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.
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.
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.
Digital amplifier designs based on Class D technology offer significantly better efficiency compared to traditional Class AB amplifiers. Besides lower heat dissipation, Class D amplifiers require lower currents from the power supply which means less stress for the car’s battery / alternator system as well – ideal for use in modern vehicles, especially BEV's.
Thanks to continuous technological advancements, today’s high-quality Class D amplifiers also achieve top-level performance in key audio parameters such as distortion (THD), bandwidth, and damping factor – making them fully competitive with classic analog designs.
The amplifier outputs of the V TWO are bridgeable – meaning two channels can be combined into a more powerful channel. This allows, for example, a single subwoofer to be driven with significantly more power. This flexibility opens up additional options for system configuration and enables targeted power bundling – all without compromising sound quality.
The ACP allows convenient adjustment of central amplifier functions such as automatic gain configuration via the proprietary AGR (Auto Gain Ranging), manual gain setting, input mode, and input reference configuration. Instead of traditional switches or rotary controls, the modern push-button interface with LED indicators offers an especially intuitive user experience with direct visual feedback on the device.
The AGR function automatically sets the input gain with precision in just a few seconds – quickly, reliably, and without errors. It adapts the input sensitivity to the output voltage of the connected signal source, ensuring maximum sound quality. The integrated gain & clipping indicator provides real-time visual feedback – ideal for professional results at the push of a button.
The V-AMP Link is especially developed for use with HELIX V series amplifiers and optimized for maximum signal quality – perfect when additional output power is needed for subwoofers or high-performance woofers.
Our SOP technology ensures a stable output power even when the vehicle’s supply voltage fluctuates – such as during engine start-up or under heavy system load. Thanks to an intelligent voltage management in the power supply, the amplifier's performance remains consistent, delivering dynamic and precise sound at all times. Especially ideal for vehicles with dynamic alternator regulation and unstable voltage conditions.
The switched power supply ensures a constant internal supply voltage even during short voltage drops down to 6 Volts (e.g. during engine start), so the functionality of the device remains stable and unaffected.
