Manley Labs Dual Vocal Combo Manuale Utente

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.

The Dual Vocal Combo is the result of a suggestion to combine the "Langevin Dual Mono
Microphone Preamplifier with EQ" with the "Langevin Dual-Channel Electro-Optical Limiter" for
a competitively priced stereo or 2 channel VoxBox-like product. Both the mic preamp and the
Langevin EL-OP are recognised as great values and serious high performance all-discrete professional
units. While the combination is not quite a "solid state VoxBox" because it doesn't have some of the
compressor & EQ functions and no de-esser, it is 2 channels of the "essentials" for half the price.

The "Combo" is 100% discrete transistor in the signal path and there are no op-amps except to drive
the LEDs in the Opto circuit, and the Meter circuit. Negative feedback is minimal, only one
transformer (mic input) per channel and much of the components are the same as in the Manley tube
gear. While we were planning this unit we upgraded the front panel Instrument Inputs for higher input
impedance (150K ohms) and higher gain (25 dB more) so virtually all guitars, bassers and synths and
drum machines could be recorded direct-to-tape comfortably.

Thank you again, and please enjoy!
