“This is my new go-to. Everything I need, nothing I don’t.”
The name originates with Rupert’s birthplace – Newton Abbot, England – and reflects the sonic journeys of his life: from Newton Abbot to Wimberley, vintage to modern, and everything in between. This is a truly versatile, world-class channel strip capable of bringing any source to life with the classic sound of Rupert Neve Designs.
The Input Stage and Mic Preamp
The Newton’s microphone preamplifier contains all the tone and musicality expected from a Rupert Neve Designs piece. This preamp makes it incredibly easy to quickly dial in a tight, clean and detailed sound; and with a robust 72dB of gain including 6dB of fine trim control, the Newton is ideally suited for a wide variety of sources.
While the input stage is tailored to be an ideal match for standard microphone source impedance, it is equally happy being driven by line levels – so a pair of Newtons can also be put to use as a high-end mixing tool for any studio. The Newton also includes our distinctive variable high-pass filter with a comprehensive frequency range adjustment and independent bypass switch, allowing the engineer to quickly eliminate unwanted noise, rumble or other low frequency build-up in the source signal.
The Equalizer
The EQ section in the Newton is optimized for speed & flexibility with a simplified set of controls. The low and high frequency shelf bands are controllable with accurate 31-detent potentiometers that provide up to 12dB of gain boost/cut, providing the ability to dial in either subtle or extreme settings as desired.
The parametric mid-band of the Newton EQ section includes another 31-detent potentiometer and a wide range of mid frequencies to boost or cut, switchable from 220Hz to 7kHz. This makes the MF band particularly flexible, allowing for taming low-mid muddiness, boosting mid frequency presence, or removing any harshness in the upper midrange. The carefully-chosen fixed Q setting maintains a healthy balance of musicality and precision – just wide enough for brush-stroke equalization without adversely affecting neighboring frequencies.
As with every section of the Newton Channel, the EQ has an independent bypass button for double- checking settings every step of the way.

The Compressor
The Newton Channel also contains the latest iteration of Rupert Neve Designs’ ultra-smooth VCA compressor, with +20dB of make-up gain and ample control for any amount of needed compression while maintaining an effortless sound.
Also included is a helpful ‘pre EQ/post EQ’ push button to place the compressor either before or after the EQ section, plus an independent bypass button.
WHAT IS
Silk?
At the end of the Newton’s signal path is the unique & highly coveted variable Silk circuit, providing the power & control to amplify 2nd and 3rd order harmonics by saturating our custom Rupert Neve Designs output transformers for a vintage tonality. From a subtle transformer tonality without Silk, to significantly more color than vintage modules with the Silk / Texture circuit fully pushed, the Newton’s output stage can fill out tracks with enhanced power and sparkle.
When you apply SILK RED, you’re enhancing harmonic content generated by the highs and high mids of your source. This adds a sparkly sheen to the top end, and is often ideal for sources including vocals, snare, strings, pianos, and other acoustic instruments.
With SILK BLUE, you’re enhancing harmonics generated by the lows and low mids of your source. This tends to “beef up” a signal from the bottom up, making it a great choice for drums, bass guitars, heavy electric guitars, male vocals, and synthesizers.
Custom Transformer Outputs
The Newton Channel has a custom transformer output stage with a balanced MAIN standard line level output. Additionally, a separate -6dBu XLR output can compensate for high levels of input and Silk harmonic saturation, enabling engineers to fully drive the Newton to achieve more transformer harmonics without clipping the next device in the chain. Both outputs are active and can be used concurrently.

REVIEWS
“…Mr. Neve’s philosophies, techniques and methodologies live on in the engineering and design team, who he trained and mentored…this rich heritage is exemplified in the new Newton Channel.”
“…the Newton Channel is RND’s most accessible channel strip in terms of its price, and it is arguably also their most accessible and intuitive in terms of operation…”
“Its overall sonic performance is impressive and it displays all the quality and characteristics you’d expect of an RND design. It also allows you, quickly and intuitively, to achieve great‑sounding results. This, together with the Texture/Silk combination, distinguishes the Newton Channel from its obvious competitors and, to my way of thinking, more than justifies its price. It may not be what most readers would call inexpensive but it is, as I mentioned earlier, the most affordable complete channel strip RND have produced.”
Bob Thomas // Sound On Sound
“We award full marks to Rupert Neve Designs for this exceptionally capable and versatile channel strip, which not only sounds fantastic, but is also well laid out and boasts excellent build quality. The Newton isn’t a bargain basement design by any means, yet it could be the best hardware investment you ever make.”
John Pickford // MusicTech
“This is my new go-to. Everything I need – nothing I don’t. What will I do with all the patch cables I just freed up?”
Korey Richey // LCD Soundsystem
“This pre is FIRE.”
Thomas “Tillie” Mann, Engineer
Lil Baby, Migos, Lil Yachty
“The Newton packs a huge punch in just 1U. Driving the Rupert Neve pre alone gives an instant edge to vocals; combine that with the flexible EQ, transparent compressor and Red Silk sparkle, it’s a one-stop shop.”
Scott Maxwell, FOH Engineer
Calvin Harris, Central Cee, Anne-Marie, Leona Lewis, Ellie Goulding
“This channel strip blew my mind, and it has been on every single mix since the day they showed up…it has beat out my existing vocal chain on the last several songs I’ve mixed. Like, beat my EQ, beat my compressor…I have a decent amount of outboard gear, but these are special.”
Colt Capperrune (scroll up to MEDIA to watch the video)
“It’s rewarding when outboard like this becomes part of the performance and song itself…”
“Even better than one Newton are two Newtons for stereo bus work. Each processed track seems to come through more clearly defined, occupying its own separate space between the speakers. Under his breath I heard J.P. say, ‘I wish I had a dozen of these,’ and his studio features a Wunder Audio console…he did end up buying a Newton for acoustic guitar tracking and mixing.”
Alan Tubbs // Tape Op Magazine
“I always find it gratifying when audio equipment really behaves in practice as the theory suggests. The preamp of the Newton Channel delivers extremely high-quality results with pronounced but smooth highs.”
Alexander Berger // Bonedo.de
“After using the Shelford Channel as a staple in my vocal chain for years, I was excited to try the Newton. I am a big fan of VCA comps on rap vocals so the Newton seemed like a great choice for Central Cee. It did not disappoint! I barely needed to touch the vocal fader as it just sits on top of the mix and soars to the back of the arena! Coupled with the 5045, the vocal sound I am able to achieve is clean and powerful. I won’t be going anywhere without these units.”
Jonny Williams, FOH Engineer
Central Cee, Thundercat
“Well I just got my Newton and ...how can I say this... it is what they said it is. I don’t own the Shelford but I don't think I need one more than I want one after getting the Newton. Everything, and I do mean everything sounds good thru it. The most shocking part of this equipment is the Compressor!! This hits waaay over its weight class…”
"This is my first piece of analog gear. I wanted to improve my quality from the source and have less of a hassle trying to 'fix' what I've recorded. This product does that and more. ...the Newton is a tribute to the past and a wink to the future."
"This channel strip made me a believer in analogue gear again! The Silk mode on this channel strip is something magical."
“I was originally going to go with the **** but like c'mon, this is something I couldn't pass up on. The Pre-amp, The EQ, the Compressor and a texture control knob. I have a WA-8000 mic and then this, everything sounds amazing. So much flavor, body, texture and color. I really don't think there is better in this price range…One of my friends kept on saying bro don't spend the money on it I have plugins that can do all that. He came over to check the bad boy out and he got way too excited by the quality difference.”
“Been playing around with the [Newton] this evening and boy. This is some high end goodness. Very very musical and transparent.”
“Update: tried the Newton with my Manley Ref C and it makes me want to sell all my other pres…not gonna happen but still. It’s that damn good…just amazing piece of gear.”

FREQUENTLY ASKED QUESTIONS
Yes, you can absolutely feed a line level signal to the Newton Channel – and a pair of Newtons makes for an amazing mix bus processor. Just make sure you have the Mic Pre GAIN set to 0dB (and that +48V Phantom is turned OFF) before plugging in any line level sources.
The Newton Channel contains our latest iteration of our VCA compressor and is designed to be gentle and smooth, keeping transients largely intact.
If you are looking to fully drive the output transformer to impart the non-linear harmonic content that adds dynamic richness to the sound (and you don’t want to clip your converters) the -6dB output is the way to go. If you want maximum headroom, use the main output.
Yes! They are isolated from one another and can be used simultaneously.
The main difference is the Shelford uses a custom Rupert Neve Designs transformer on the input stage to impart a more 'vintage' tone on the way in, while the Newton Channel Mic Pre is designed without an input transformer, which makes it capable of a slightly more modern & clean sound – similar to our award-winning 5211 Mic Pre.
This doesn’t mean the Newton can’t do “the vintage thing” though – remember, most of the tone from a Rupert Neve mic preamp actually comes from saturating the output stage, which you can fine-tune here to great effect using the Silk circuit.
The Newton Channel EQ uses more modern style circuitry to create a fully parametric mid and swept HF and LF shelves. These circuits are both more accurate and more transparent than the vintage-style inductor EQ in the Shelford Channel.
This switch isolates XLR Pin 1 from the Newton chassis ground in order to help eliminate ground hum.
The Newton Channel doesn’t have its own high impedance input, but any DI (such as the RNDI) can work with the Newton Channel preamplifier.
Yes. Just like all Rupert Neve Designs products, the Newton Channel is made with pride in the USA.
