Manley Enhanced Pultec EQP-1A


MANLEY LABORATORIES is the only authorized user of the original Western Electric passive EQ circuitry previously licensed to Pulse Techniques, Inc. found in the well-known (and still sought after in the used market) antique Pultecs. (Yes, we bothered to hunt down Eugene Shenk about ten years ago in New Jersey to ask for his permission and blessings. EveAnna was there.) EQ may be set to 'flat' positions or BYPASSED entirely. All BOOST and CUT controls are continuously variable conductive plastic potentiometers for absolutely silent operation and long life. Our single rack unit monoblocks occupy one-third of the space of the 'antique Pultecs', an important consideration for allocation of outboard rack space. And if you notice, we've added a couple extra frequencies too. 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.

People often ask us if our Pultec EQ's sound like the old ones to which we reply, "Yes! But better! The originals had three transformers in the signal path whereas ours can be used completely transformerless. Our Manley Enhanced Pultec has a vastly superior B+ power supply, with regulated and balanced heater supply. Our line amp is known to be killer-sounding. The components we use 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!"

The MANLEY PULTEC EQP-1A, now available in both single and 2-channel versions, uses 1 x 12AU7WA and 1 x 6414 in our ALL-TUBE single-ended line amplifier for the gain make-up and extra-beefy sound; gain is factory set for unity but additional gain is available by a rear mounted feedback adjustment trimpot. Like our 40dB Mic Preamps, the Manley Pultecs offer both transformer coupled balanced and direct capacitor coupled unbalanced outputs for easy interface and sonic variety.

Kick drum? Bring on the Pultecs and all the iron you can muster! 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 cut. You'll see. There's no substitute for a Pultec!
