A recreation of the legendary Pultec EQP-1, this EM-EQ2 is for sale in perfect working order and excellent condition.

Made by A Designs Audio in California this a high quality, well-built, dual mono 2U rack EQ unit. One turn of the knobs on this and you can feel just the right balance of resistance and smoothness that doesn’t so much shout as gently whisper “quality” at you. This is a superb modern EQ unit that works beautifully whether you’re tracking or mixing – sounds great across the 2 bus.

Essentially you’re getting A Designs’ modern take on two Pultec EQP-1 units in one box, with the advantage of fully-balanced, noise-free performance and modern impedance spec (and without a price tag that will break the bank). For the full spec and features head to the A Designs EM-EQ2 page.

We’ve tested it to be certain it is in full working order, however this was a mistake as we are now trying to find excuses to keep it for the studio. It really is as good as the spec suggests – one of those pieces of kit that just seems to make everything sound better. 

Switch-able voltage for use anywhere in the world.

From the A-Designs Site:

Many engineers and musicians would love to own an original Pultec EQP-1 equalizer, but the simple truth of audio equipment is that – unlike violins and brandy – electronics don’t improve with age. Even if you can find one on the vintage market that’s in decent shape and fully functional, the exorbitant price tag can be somewhat preventative…and the maintenance a potential nightmare. The A-Designs Audio EM-EQ2 is the answer for those who want the stellar sound of a Pultec equalizer plus the added benefit of modern performance and reliability.

The EM-EQ2 faithfully preserves the EQ section design, control layout, and wonderfully smooth 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 3k, 4k, 5k, 6k, 10k, 12k, 16kHz; and, of course, the low band can be boosted and/or attenuated at 20Hz, 30Hz, 60Hz, or 100Hz. Boost and attenuation can be adjusted from 0dB to ±10dB.

Eminently suited for tracking, mixing, or mastering, the two-channel EM-EQ2 is housed in a rugged, metal 2U chassis. It shares the same custom-milled faceplate, brushed-aluminum control knobs, big jewel power indicator lamp, and heavy-duty Carling toggle switch as the A Designs Hammer (which compliments the EM-EQ2 perfectly). Additional features include a proprietary nickel-core Cinemag output transformer, Wima capacitors, and true hard bypass. Instead of using common off-the-shelf chokes, A-Designs Audio employs a Cinemag custom wound tapped inductor.

Along with the classic EQ circuitry, layout, and exceptionally musical tone of the original Pultec, the EM-EQ2 offers fully balanced, noise-free performance and modern impedance specs, making it easy to integrate it into any environment.

Here’s the best part: with its dual-mono design, the EM-EQ2 gives you two Pultecs for a fraction of the price of one, making it easier than ever to add the Pultec magic to any project or professional recording studio or live rig.
