INTRODUCTION THANK YOU!... for choosing the Langevin Dual Vocal Combo. Manley Labs bought all the rights to the Langevin name and circuits in 1992. Manley uses the Langevin name for its solid state products including versions of an all discrete Pultec and Electro-Optical Limiter, and Mic Preamp.

J) DIRECT INPUT. This is for plugging in an electric guitar, bass, synth, etc into the Dual Vocal Combo. The input impedance is high (150 kOhms) appropriate for these instruments and there should be plenty of gain available. Electric guitars and basses may need a fair amount of H.

MIC PRE BASICS 7 This Microphone Preamp, like most mic preamps, is pretty easy to use. First we can discuss why outboard mic pre's have become "a must have item" in almost every studio .
CONNECTING YOUR PREAMPLIFIER 8 Easy - Connect the mic to the Microphone Input XLR, then connect the Line Output to your tape machine or console. Read on, there are some things to consider. On the back panel are female XLR's labelled MIC INPUT A and MIC INPUT B.
9 Reversing the polarity or phase is often needed when two or more mics are picking up the same source. For example it would be needed when one mics the top and bottom of a snare - one skin is going towards one mic and the other skin is going away from the other mic.
OPERA TION NOTES The Langevin Electo-Optical Limiter follows certain traits and traditions established by the UREI LA-3A and similar levelling amplifiers. These traits can be divided into two aspects - electronic and operation. The electronic concept is simple and rather clean.
The slope or ratio is also difficult to simulate. The initial ratio is low and becomes higher with more gain reduction until the leds light up fully and further reduction is not easy.

TROUBLE-SHOOTING There are a number of possible symptoms of something not quite right, some may be interfacing, others we will touch on as well. The Dual Vocal Combo has a variety of balanced and unbalanced inputs and outputs optimised for typical standards and most problems are due to the right cable in the wrong jack.
HUM - Let's assume it knows the words. Once again - several possibilities - several cures. Most likely it is a ground loop. The two most common procedures are: try a 3 pin to 2 pin AC adapter (about a dollar at the hardware store) which is better than messing up the power cable by bending the ground pin until it breaks off.
INTERNAL ADJUSTMENTS 1 7 4 5 9 10 6 8 3 1) +36 Volt DC adjust with meter from ground to resistor marked by arrow. Check this first and adjust if needed. It is the power supply regulator adjustment. Now for the audio .... You will have to start out by setting front panel controls to these settings.
REPLACING FUSES & METER LAMPS Changing the fuse is easy and can be done without any tools and while the DVC is still in a rack. 1) Disconnect the IEC AC mains for safety 2) Rotate the fuse cap ant.
MAINS CONNECTIONS Your unit has been factory set to the correct mains voltage for your country. The voltage setting is marked on the serial badge, located on the rear panel. Check that this complies with your local supply. The voltage changeover switch is located inside the unit in the middle of the PCB near the power transformer.
