Description

The LANG 312L is a high-performance 500-series preamp designed to capture the powerful, dynamic energy associated with classic New York-style audio processing. Ideal for studio enthusiasts and professionals alike, this preamp delivers exceptional sound quality and versatility, all at a fraction of the cost of similar units. With up to 90 dB of gain, it's more than capable of driving even the most gain-hungry microphones, like ribbons and vintage mics, without the need for external boosters. This allows users to unlock the full potential of their microphones, delivering sound quality that's clear, responsive, and free from unwanted noise.

Equipped with custom-made HA-880 op-amps, CineMag transformers, and switchable features like 48V phantom power, a -20 dB pad, and phase reversal, the LANG 312L is tailored for a variety of recording needs, from vocals to instruments. Its front-panel XLR/TS combo jack provides easy access for different input types, while the built-in +25 dB lifter ensures pristine audio performance even in challenging setups. All of this comes in a compact, single-space 500-series module that is ready to bring professional sound to your recordings with legendary NYC flavor.
