The Neumann V-402 is a dual-channel microphone preamplifier designed for the highest fidelity in both studio and live sound applications. Engineered to preserve the integrity of your sound, it offers transparent amplification with ultra-low noise and distortion.
The V-402 is Neumann's first-ever standalone microphone preamplifier, building upon decades of experience in microphone and studio equipment manufacturing. It is designed to meet the demands of modern recording environments while honouring the company's legacy of high-quality audio equipment.
The V-402 offers up to 60 dB of gain, utilising a carefully designed amplification circuit that aims for transparency. High-quality components and meticulous circuit design ensure that the original timbre and tonality of your microphone and source material are preserved.
The preamplifier employs a unique circuit topology that minimises electronic noise, boasting an impressive signal-to-noise ratio. This makes it ideal for critical recording applications where even the slightest noise or distortion could be detrimental.
The V-402 features DI inputs, allowing for the direct connection of instruments like guitars and keyboards. These inputs are designed to handle high-impedance signals without colouration, providing a clean and unaltered pathway into your recording system.
Input pads are included for handling high-level audio sources, offering a -20 dB reduction. These pads provide additional headroom, ensuring that the preamplifier can accommodate a wide range of input levels without compromising sound quality.
An integrated headphone amplifier with its own volume control facilitates real-time monitoring. This feature allows both engineers and musicians to listen to the input signal directly, providing immediate feedback and enabling precise adjustments during recording sessions.
The V-402 is a dual-channel preamplifier, allowing for two microphones to be amplified simultaneously. Each channel has its own set of controls, ensuring independent operation and flexibility in multi-mic setups.
The V-402 is built with a rugged metal chassis and high-quality internal components, designed for durability and long-term reliability in both studio and live sound environments.
