Langevin Dual Vocal Combo Stereo Pre/ EQ / Limiter

Dual Vocal Combo Stereo Pre/ EQ / Limiter description:

The Langevin DUAL VOCAL COMBO Stereo Pre/EQ/Limiter. Highly flexible, respected worldwide as the complete vocal box solution and is also great for instrument and mix tracking.

The Langevin DUAL VOCAL COMBO is a 2 channel microphone preamplifier with 2 shelf equalizers plus 2 channels of electro-optical limiters. The combo combines two of the most popular Langevin products and is very affordable, half the price of the VOXBOX combo (Manley's valve equivalent). 2 channels of great sounding all discrete channel strips. The DVC includes VU meters, individual phantom power, limiter linking and time proven circuitry. This is an ideal box for musicians and engineers on a budget and is equally at home in a big league studio, mobile recording truck, or live gig. It has the reliability, functionality, and the sound without the any of the complexity. Easy on the wallet, easy to use. The Mic Preamps are transformer coupled (hand wound by Manley Labs) with 50 dB of gain provided by pure discrete transistor circuits, same as found in the stand- alone Langevin Dual Micpre. 48 volt phantom power can be applied to each input XLR independently and the switches are a locking type to prevent accidents. The front panel has 1/4 inch Direct Instrument inputs with appropriate input impedance (500Kohms) providing about 40 dB of gain. The Equalizers are comprised of a low frequency shelf that can be switched to either 40 Hz or 80 Hz and a high frequency shelf that can be set for 8 KHz or 12 KHz. These shelves are continuously variable from -10 dB to +10 dB of gain. The EQ can be completely switched out with the BYPASS switch making it easy to make a choice. The Limiters are the discrete transistor version of the Manley ELOP Limiter (same as the Langevin stand-alone version). This type of limiter is superb for vocals and a wide range of instruments from basses and guitars to synths and room mics. When it comes to tracking and fast set-ups, the lack of a multitude of controls is a real feature. You can simply set up the Threshold and Gain controls and expect that the limiter will do the right thing without a lot of tweaking. The Limiters have Threshold and (make-up) Gain controls, a Link switch for stereo and a pair of toggles that switch the VU meters to Gain Reduction or Output Level. These are true stereo limiters without the usual problems of left/right matching common to other stereo opto based limiters. The back panel has XLR mic inputs paralleled with 1/4 inch TRS jacks that feed the mic pre stage. By popular request Manley/Langevin have added separate 1/4 inch TRS micpre outputs which "normal" into the 1/4 inch TRS limiter inputs so they can be permanently wired into a patchbay. There are Direct Outputs from the Mic Pre/EQ stage so one can indeed use the mic preamps and the Limiters as 4 separate sections. The main outputs are available as either transformerless balanced XLR or unbalanced 1/4 inch Tip-Sleeve jacks.
