The Newton Channel is a powerful channel strip that 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.
 
The Equalizer
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.
 
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.
 
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.
 
The Front Panel Features
Mic Gain
12-position rotary switch that controls the microphone preamp gain in 6dB steps. For line level input signals, set the Mic Gain to the “0dB” position.
48V
Push-button switch that illuminates RED when +48V Phantom Power is engaged.
Ø (Polarity)
Push-button switch that illuminates AMBER when engaged and inverts the phase of the preamp signal.
TRIM
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.
MID
31-detent potentiometer that controls the amount of boost or cut for the MID FREQ peaking EQ within a range of +/- 12dB.
8K/16K
Push-button switch that selects between the two available high frequency shelf frequencies: 8kHz (OUT) and 16kHz (IN).
HF
31-detent potentiometer that controls the amount of boost or cut for the high frequency shelf within a range of +/- 12dB.
COMP IN
Push-button switch that illuminates GREEN when the compressor section is engaged.
THRESHOLD
31-detent potentiometer that controls the compressor threshold range from +20dBu to -30dBu. When the input signal rises above the set threshold level, compression begins with a soft-knee at a 2:1 ratio.
RELEASE
31-detent potentiometer that controls the compressor release time. The overall timing range available is 50mS (FAST) to 500mS (SLOW).
GAIN
31-detent potentiometer that controls the compressor make-up gain within a range of -6dB to +20dB.
PRE EQ
Push-button switch that routes the compressor section ahead of the EQ section when engaged.
SILK
Illuminated push-button switch that toggles through the three available SILK modes: OFF, RED, and BLUE.
TEXTURE
31-detent potentiometer that controls the amount of SILK harmonics added within the transformer output stage when SILK is engaged.
GR and OUT Metering
8-segment LED meters that indicate compressor gain reduction (dB) and output level (dBu).
POWER
LED that illuminates GREEN when the Newton Channel is powered ON.
