Rupert Neve Designs Newton Channel Mic Pre + EQ + Compressor with Silk

The Newton Channel includes a fully Class-A mic preamp, a musical, 3-band discrete EQ section, a fast
& flexible VCA compressor, and custom Rupert Neve Designs transformer-coupled outputs with our
revolutionary harmonic color stage: variable Silk Red & Blue.
The Input Stage & 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.

Variable 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.
With the variable Texture knob, the engineer is able to precisely dial in the desired amount of harmonic
density – with Silk Red mode highlighting harmonics in the highs and upper mid frequencies, and Blue
mode accentuating harmonics in the lows and low mids. 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.

 

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.

31-detent potentiometer that allows the user to adjust the preamp gain within a range of +/- 6dB.
HPF
Push-button switch that illuminates GREEN when the high pass filter is engaged.
FREQ
31-detent potentiometer that allows the user to adjust the cutoff frequency of the Sallen-Key high pass
filter within a range of 20Hz to 250Hz.
EQ IN
Push-button switch that illuminates GREEN when the EQ section is engaged.
LF
31-detent potentiometer that controls the amount of boost or cut for the low frequency shelf within a range
of +/- 12dB.
60/150
Push-button switch that selects between the two available low frequency shelf frequencies: 60Hz (OUT)
and 150Hz (IN).
MID FREQ
31-detent potentiometer that controls the frequency of the midband peaking EQ within a range of 220Hz
to 7kHz.
