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.

Optimised For DSP Based Systems
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. Thus ensuring maximum transparency and sonic fidelity. Perfectly suited for DSP-driven audio setups.

V-AMP Link – High-Level Input Tailored For V Amplifiers
The integrated V-AMP Link is a specially developed high-level input, perfectly matched to the speaker outputs of the V series. The key advantage is that 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.
