The Pultec EQM-1A3 two-band mastering equalizer, the modern-day version of the legendary EQP-1A equalizer, can give your tracks the massive bass, silky highs, and addictive warmth that made the original a studio standard. Pulse Techniques is back, building their classic EQs right here in the USA, without compromise or "enhancement" to the original designs. New Pultecs like the EQM-1A3 contain only original-spec components and are dead ringers for their vintage ancestors. And with stepped controls that make it easy to recall any settings, the Pultec EQM-1A3 equalizer is ready for your mastering sessions.

Thank Pultec for decades of amazing recordings

Magical tools revered for their ability to improve the sound of audio simply by passing signal through them, Pultec equalizers like the EQM-1A3 are the stuff of legend. You've heard them on countless hits. Rare vintage units cost a pretty penny - if you can find one in good working order. So naturally, there have been many hardware and software "re-creations" over the years. Well, now you can grace your recordings with the sweet sound of the EQM-1A3: a genuine, made-in-America Pultec EQ.

Boost, cut, or both - it all sounds great

Take a look at the Pultec EQM-1A3 and you'll see it's not designed like your typical equalizer. The two-band design basically gives you flexible low shelving, along with broad-bandwidth midrange peak control. Because the boost and attenuate controls work independently you can use an old trick to add weight to the bass region while also notching a bit above the cutoff point, by boosting and attenuating at the same time (try it on kick drum and you'll never look back). On the high-frequency side, you can set separate ranges for the boost and attenuation. Said another way, you can boost at 12kHz and cut at 5k, adding "air" to a track without increasing presence.

Precise stepped controls for accurate recall

When you're mastering with outboard gear, it's crucial to be able to accurately recall settings. The EQM-1A3 mastering equalizer sports 21-position stepped switches for its boost/attenuation controls. The tapers have been engineered to give you a maximum of 10dB of boost/cut, with .5dB step increments. So when you need to recall exact settings, the EQM-1A3 makes it easy and precise.

Pultec EQM-1A3 Two-band Mastering Equalizer Features:
  • Single-channel, two-band equalizer built exactly like the original, legendary Pultec units
  • Combines the vintage character of original Pultecs with the reliability of modern design
  • Incredibly low noise floor for a pure sound
  • 21-position stepped switches make setting recall easy
  • Bandwidth control lets you decide how wide a range you're sculpting
  • Separate boost and cut controls provide some extra creative potential
Pultec is back and better than ever with the EQM-1A3!
