Manley Enhanced Pultec EQP-1A Mono Tube EQ
The Manley Enhanced Pultec EQP-1A Mono Tube EQ is Manley's interpretation of the historic Pultec Equalizer as originally produced by Pulse Techniques, Inc. The Manley Pultec units employ their own simple and clean all-tube make-up gain block to reamplify the signal after the passive EQ circuit. 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, a couple extra frequencies have been added as well. 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 in that switch's middle position.
Original Pultecs had three transformers in the signal path whereas Manley's can be used completely transformerless. The Manley Enhanced Pultec has a vastly superior B+ power supply, with regulated and balanced heater supply. Manley's line amp is known to be killer-sounding. The components used today just weren't available in the 1960s.
The EQP-1A uses 1 x 12AX7WA and 1 x 6414 (or 5965) in the 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 40 dB 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 what a Manley Pultec EQ can do!
