Manley Langevin Dual Vocal Combo 1999 - 4/2001 LDVC000 - LDVC178 - Manual (Page 3)

INTRODUCTION
THANK YOU!...
for choosing the Langevin Dual Vocal Combo. Manley Labs bought all the rights to the Lan-
gevin 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 ELOP are recognised as great values and serious high performance
all-discrete professional units. While the combination is not quite a “solid state VoxBox” be-
cause 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, basses and synths and drum machines could be recorded direct-to-tape comfortably.
Thank you again, and please enjoy!
