Langevin All-Discrete Pultec EQP-1A
The original Pultecs had three transformers in the signal path whereas this new Langevin (built by Manley Labs) can be used completely transformerless. The Manley Enhanced Pultec has a vastly superior B+ power supply, with regulated and balanced heater supply. The line amp is known to be killer-sounding. The components Manley Labs uses today just weren't available 20 years ago. So, if you want a project with crackling carbon pots, dirty open frame wafer switches, 5% and 10% tolerance noisy carbon resistors, exposed tubes sticking out the back of the 3U chassis, etc., go pay top dollar for an antique Pultec!"
All BOOST and CUT controls are continuously variable conductive plastic potentiometers for absolutely silent operation and long life. The single rack unit monoblocks occupy one-third of the space of the "antique Pultecs", an important consideration for allocation of outboard rack space. The rear mounted input switch selects 0 degrees or 180 degrees PHASE INVERT for the balanced gold pin XLR input or the transformerless unbalanced bridging input (1/4" jack) may be selected.
Kick drum? Bring on the Pultecs! You'll soon discover the power and magic of having those individual Low Frequency BOOST and CUT controls in that LF shelf circuit... Need a little clarity or extension? Try that middle bell-shaped Boost dialing in the sharpness of the boost on the BANDWIDTH control. Something bugging you? Ease it off with the HF shelf control. You'll see. There's no substitute for a Pultec!
The Langevin unit works the same way as the Manley unit but instead has an ALL-DISCRETE make-up gain amplifier with both balanced and unbalanced inputs and outputs -- all completely transformerless. It is known to have an incredibly sweet top end.

Langevin was one of the original pro audio manufacturers dating back to WWII. In that era there were far fewer audio manufacturers and Langevin gear was very popular and especially respected in the broadcast industry. There were very few recording studios then and most of them relied on Langevin, Altec, Fairchild, and other great brands as well as home-made gear. Early Langevin equipment was vacuum tube based and later became mostly discrete transistor based. Today, you can often find vintage Langevin pieces still in use after all this time.
The Manley units are all-tube while the Langevin units have all-discrete make up gain amplifiers. The EQ or limiting and metering sections are all the same Manley-to-Langevin. Your choice becomes between the sound of discrete transistor cicuitry in the Langevin gear or vacuum tubes with and without transformers in the Manley gear. Different flavours, but all build side-by-side with all high quality parts and reliable construction techniques at the Manley Labs factory.
