Pack your 500 Series rack with Classic Neve EQ

The Rupert Neve Designs 551 is a 3-band, custom-tapped inductor EQ inspired by classic Neve console equalizers. The low-frequency band is revered for its creamy, rich bass. Unlike Rupert's vintage designs, however, the 551's LF band may be used in either a peak or shelf mode to give you amazing control over the punch and girth of your low end. The 551's inductor midrange band is perfect for sweetening vocals and instruments while nudging them forward in your mix. For those problematic frequencies, the mid band's proportional-Q response is just what the doctor ordered. The high-frequency band is a hybrid vintage/modern design that blends classic inductor circuitry with capacitor-based topologies to give you vintage sound with enhanced control.

Low-feedback, Class A discrete electronics make the difference

Rupert Neve Designs uses low-feedback, Class A discrete electronics in each EQ section of the 551, and these make a vital contribution to the equalizer's overall sound. And while these design elements are very much "vintage Neve," the 551 also leverages contemporary components and techniques that weren't possible back in the day, giving you the best of old and new.

The magical sound of Neve

Rupert Neve is an audio legend whose electronics designs defined the golden age of analog. Those of us who have had the privilege of working on a Neve 8078 or its predecessors can attest to the fact that Neve's Series 80 consoles were indeed the pinnacle of hand-wired analog mixing desks. Mr. Neve has remained at the forefront of audio-circuit innovation for over half a century, and his current company, Rupert Neve Designs, continues to advance the state of the art with cutting-edge products that sound incredible and intelligently address the challenges of the digital age. If you're still not quite sure what the fuss is all about, check out Dave Grohl's documentary, "Sound City."

Great eq

I am a newbie into serie 500 stuff, so i am getting modules to make a one channel device. I started with the dbx 520 and 560A, to use it with vocals and instruments. Then, i got the bbe sonic maximizer, to make my sounds come to life (i first knew the bbe with my guitar, and i love it!). The Radial extc came to me, to add the sound of my several guitar effects into my tracks. The next buy was this eq .... i know it is a three band eq and it is expensive, but i wanted to have an eq with its personality, which can bring to life my tracks, an eq with no harshness on high trebble settings, etc ...... well, this eq can achieve it! I am not a studio owner and also an audio engineer, i am a guitarrist who loves to record his band with the best sound possible. I always knew that this 551 would never dissapoint me, so i went for it, now i am happier than a dog with two tails!

The Best

I use this for vo and wow. Just plugging it into the signal chain makes the voice sound better. The inductors give the 551 a very 'Pultec' type of feel with broad strokes rather than precision eq'ing. If your vocal chain already sounds good, but you're looking for amazing, get the Neve 551.

Rupert Neve 551

Sounds super sweet and amazing!!!! I've got this baby following a 511 pre and feeding various tube compressors and I can't get enough of it. It's a very colorful piece, so don't buy if you don't want an eq that will impart its own character into your mix. For the rest of us, once you hear how material sounds going through it, a second one will make the wish list. Probably won't take you too long to dial in "that sound" with this puppy. Vocals are sounding soooo lush no matter if it's paired with my hardware compressors or Plug-ins of choice. Have also gotten killer Kick, Snare, and Bass results. By it, you'll want to use it everywhere too!


Great clarity on the highs. Great low end power. Great mids with lots of versatility. Great vintage warmth and saturation. It's an all-around studio quality EQ. I almost wen with the Great River EQ for less $. It had more tone-shaping capability than the Neve but I really wanted the warm vintage saturation of a classic console. I picked up a pair of these EQ's and it was a big investment for a hobbyist like myself but well worth the money.
