A-Designs EM PEQ 500 Series EQ Module

A-Designs EM PEQ - EQ Module

The A-Designs EM PEQ is 500 series Equaliser module based on the Pultec EQP-1A. Great for enhancing your bottom end and used the same discete class AB amps found in the A-Designs Pacifica mic pre.

A-Designs EM PEQ 500 Series EQ Module

A 500-Series module that captures the essence of the classic Pultec EQP-1A sound

One of the most venerated equalizers of all time, the all-tube Pultec EQP-1A has been cherished by recording and mastering engineers for its almost magical ability to improve the sound of nearly any signal running through it. Now, after considerable research and development, the A-Designs Audio EM-PEQ has captured the essence of the highly revered Pultec EQP-1A and placed it in the compact and popular 500-Series form*—with no compromise in sonics or build quality.

Along with modern performance enhancements, the A-Designs Audio EM-PEQ meticulously maintains the EQ-section design and control layout of the original Pultec EQP-1A, as well as its wonderfully smooth musicality. It also has the same frequency settings and inductors that made the Pultec a must-have for capturing the bottom end. Makeup amplification is achieved through the use of the same discrete Class AB amplifier found in A-Designs Audio's immensely popular solid-state Pacifica mic preamp—putting a slightly unique and modern twist on the classic design of yesteryear.

The EM-PEQ's controls attenuate high band at 5k, 10k, 20kHz; vary bandwidth AND boost mid to high band at 3k, 4k, 5k, 6k, 10k, 12k, 16kHz; and boost or attenuate the low band at 20Hz, 30Hz, 60Hz, or 100Hz. Boost and attenuation range from 0dB to ±10dB.

Additional features of the EM-PEQ include a nickel-core output transformer, gold Grayhill rotary switches, Wima caps, and a true hard-wired bypass. Plus, instead of using common off-the-shelf chokes, A-Designs uses a custom tapped inductor, wound to the original values as the original Pultec. Along with the classic EQ circuitry, layout, and exceptionally musical sound of the classic Pultec, the EM-PEQ offers fully balanced, noise-free performance and modern impedance specs for easy operation and fast studio integration.

In the world of pro audio recording, there are two types of equalizers: those that you don't want to hear in action ("surgical or corrective EQ), and those that you do ("color, or character" EQ). The EM-PEQ is one you most definitely do. Unlike any other 500-Series equalizer, the A-Designs EM-PEQ sits on the extreme end of the "character" bench. It focuses on "correcting" that which cannot be fixed by so-called surgical EQs: the enhancement of tone and musicality.

The EM-PEQ is also available as the EM-EQ2, a 2-channel, 2U rackmount version offered at the same price as two EM-PEQs and a 500HR power rack. Whether you prefer to work with the 500-Series form factor or standard rackmount format, both the EM-PEQ and EM-EQ2 are identical in both sound quality and functionality.

* The EM-PEQ is an approved API™ VPR Alliance product and may also be used in Brent Averill Enterprises racks, and the 2-bay A-Designs Audio's 500 HR power supply/rack. The EM-PEQ requires 48V to operate. Please check your power rack for this feature before purchasing an EM-PEQ.

Custom transformers—the secret of A-Designs EM PEQs 500 series sound

In order to achieve the quality of sound that brings a smile to your ears, a profound understanding of electronic components and how their inherent qualities affect sound is essential. Transformers hold a singular position in circuit design due to their ability to affect timbral quality. Apart from the utilitarian task of electronic isolation for noise-free operation, the alloys used for the transformer's winding along with the number of windings, will impart a distinct sonic quality. For example, nickel-wound transformers provide a more transparent sound with an airy high end, while steel can impart a thick "Neve-like" midrange or low-end "API growl."

To give each preamp in the A-Designs Audio EM-Series its own unique character, each has custom-wound transformers that employ proprietary A-Designs alloys that have been ear-tested to produce just the right sound for the right application. But that doesn't mean that the EM-Series preamps are one-trick ponies—far from it. What it does mean is that decades of collective experience between A-Designs Audio and highly respected audio professionals who beta test A-Designs products have taken guesswork out of finding the right preamp for the job. Think of each of the EM series preamps as the ruler of a specific domain in the frequency spectrum. For example, the EM-Silver rules the lower frequencies thanks to its steel-wound transformer, making it a perfect choice for bass or kick drum, while the EM-Blue's nickel transformer provides the clarity and highs needed to bring out the "crack" on snare drums.

With various combinations of EM-Series modules you can create a lunchbox dedicated to recording drums, channel strips with Pultec-style EQ, or simply have a preamp for all seasons in one convenient location.

Let A-Designs Audio's EM-Series 500 modules be to be your guide to a world of color and sound that will inspire both you and your recordings.
