Lang 312L

NY-Style Preamp with Built-in Lifter

The new LANG 312L is simply bursting with dBs…. With up to 90dBs of gain, it’s equipped with more power than almost any other Preamp out there. Now, you’ll be able to use each and every microphone in your collection without the need for any external boosting, and not even break a sweat. Especially useful for all you Ribbon and Vintage Mic users that never seem to be able to get the most from them…

Thanks to its extremely low internal noise and impressively fast response, you’ll actually hear dynamics you never knew existed.

Microphone input impedance: 1200 Ω , 10KΩ with lifter engaged, perfect for lo gain ribbon mics. Input is transformer balanced and floating.
Line input impedance: 10 kΩ bridging, transformer balanced and floating.
DI input impedance: Greater than 2 MΩ, unbalanced.
Output impedance: Less than 75 Ω, transformer balanced and floating, to drive a load of 600 Ω (factory unterminated).
Maximum output: Greater than +30 dBu into 600 Ω.
THD: Less than 0.005 % at 1 kHz, less than 0.01 % at 100 Hz.
Frequency response: 20 Hz (+0.3 dB) to 20 kHz (-0.2 dB).
Maximum gain: 90 dB.
Noise: Less than -130 dBu EIN unweighted.
Power consumption: 50 mA per rail ±16 V DC.
