INTRODUCTION
THANK YOU!...
for choosing the Langevin All-discrete Pultec Type Equalizer. The Langevin Pultec Equalizer utilizes the original
WESTERN ELECTRIC passive-equalization circuit found in the long-out-of-production and justifiably famous
PULTECS. It is also the exact EQ section found in our MANLEY Enhanced Pultec EQ, the difference being that
the Manley unit uses and all-tube make up gain amplifier while the Langevin employs an all discrete make up gain
amplifying circuit. Our versions of this classic EQ incorporates superior modern components with our proven line-
amp superiority for absolute sonic cleanliness... Conductive plastic potentiometers and sealed gold-contact
switches, polystyrene and rolled film and foil capacitors, precision 1% metal-film resistors (no cheap carbon
resistors here!), solid, rugged, servicable, yet handsome metal and chassis work, combine with a cleverly regulated
power supply and state-of-the-art solid state circuitry to bring the PULTEC into the nineties and beyond....
You have purchased our Rev. B version which now features all-discrete balanced inputs and outputs as well as
additional unbalanced inputs and outputs. All inputs and outputs are protected against shorted terminations. The
headroom and noise floor of this unit have been greatly improved over our early units.
Please take a few moments to read through this manual carefully as it contains information essential to proper
operation of this unit.
Thank you again, and please enjoy!
