The A Designs EM-PEQ is a single-channel 500 series 3-band equalizer that faithfully reproduces the Pultec EQP-1A, a legendary studio piece revered for its distinct tonal characteristcs and unique controls. It's great for tracking and mixing, and two EM-PEQs can be used together for mastering as well.
The EM-PEQ preserves the EQ section design, control layout, and musicality of the original Pultec. It also has the same frequency settings and inductors that made the Pultec a must-have for accurately capturing and shaping the sound spectrum, especially the bottom end. The high band is attenuated at 5k, 10k, 20kHz; bandwidth and boost can be varied mid to high band at 3, 4, 5, 6, 10, 12, 16kHz; and the low band can be boosted and/or attenuated at 20, 30, 60, or 100Hz. Boost and attenuation can be adjusted from 0 to ±10dB.
Additional features of the EM-PEQ include a nickel-core Cinemag output transformer, gold Grayhill rotary switches, Wima capacitors, and a true hard-wired bypass; plus, instead of using common off-the-shelf chokes, A-Designs uses a custom tapped Cinemag inductor wound to precisely the same values as the original Pultec.
Along with the classic EQ circuitry, layout, and exceptionally musical sound of the EQP-1A, the EM-PEQ offers fully balanced, noise-free performance and modern impedance specs for easy operation and fast studio integration. Makeup amplification is achieved through the use of the same discrete Class AB amplifier found in A-Designs Audio's solid-state Pacifica mic preamp, putting a slightly unique and modern twist on this classic design.
