| Rupert Neve Designs' Shelford Channel, over a half century in the making, is the definitive evolution of Mr. Neve's renowned 80 Series channel module technology, updated and refined for the contemporary studio. The Shelford Channel is fitted with Rupert's latest Class A transformer-gain mic preamp, the best-of-the-classics Inductor EQ from the Shelford 5052, a punchy diode-bridge compressor, the alluring analog textures of variable Silk saturation, a state-of-the-art dual-tap transformer output stage with massive headroom, and double the operating voltage of vintage designs. Offering rich tonal options for making audacious statements with your music, along with precision-detented controls for recall, the Shelford Channel delivers the authoritative sonic essence of classic Rupert Neve designs, along with modern versatility.
Input stage and transformer-gain mic pre
Rupert Neve's first new Class A, transformer-gain mic preamplifier in over 40 years makes its debut in the Shelford Channel. Rupert has spec'd this preamp with a direct-coupled transformer input; gain is provided by the custom transformer itself. The proprietary input transformer, and its meticulous integration with the surrounding Class A input amplifiers, plays an outsized role in the Channel's immediately recognizable sonics: punchy and creamy-smooth, with excellent isolation and vanishingly low noise.
The Shelford Channel's front-panel hi-Z instrument input uses the same discrete Class A field-effect transistor with transformer topology as Rupert Neve Designs' acclaimed RNDI; for gain, however, it utilizes the new RN4012 input transformer directly into the mic preamp. This design provides astonishing clarity on hi-Z sources, with substantial low-end weight and silky-smooth high frequencies. The DI also gives you a passive thru output to feed a guitar or bass amp.
- Mic-DI/Line: switches between microphone/direct injection input and line input
- GND Lift: disconnects the audio signal ground from chassis earth
- Signal LED: green indicates Signal Present; red indicates imminent input stage clipping
- Mic Gain: 12-way precision rotary, controls gain from 0dB to 66dB in 6dB steps
- Trim: rotary switch provides further continuous gain adjustment of +/-6dB
- 48V: switch engages phantom power on the mic input
- Phase: inverts the polarity of the signal path (illuminates when engaged)
- HPF Freq: engages a 12dB/octave highpass filter, variable from 20Hz-250Hz
The best-of-the-classics inductor EQ
The Shelford Channel's EQ section is a 3-band, custom-tapped inductor circuit containing Rupert's favorite bands from his vintage equalizer designs. The low-frequency band is primarily based on the 1064 — acclaimed for its creamy, resonant bass. Unlike the 1064, though, the Channel gives you added dimension, punch, and control over your low end by letting you use the LF band as either a peaking or a shelving filter. The midrange band is based on the venerable 1073 and is perfect for sweetening instruments and vocals while nudging them forward in a mix. "Proportional Q" response also makes it ideal for attenuating problem frequencies. The high-frequency band is a hybrid design with the best of vintage and modern attributes. It should be noted that this EQ is in no way a clone; it's a decidedly modern design using components and techniques that simply did not exist in the 1970s — for instance, the use of capacitor-based topologies to achieve sonic richness and enhanced control.
- EQ In: engages all EQ frequency bands except HPF
- LF: adjusts up to 15dB of boost/cut at the selected low frequency
- Low Freq: 4-position rotary switch for selecting LF band corner or center frequency
- LF Peak: selects LF shelving (out) or peaking (in) mode
- Mid Hi Q: selects between a mid-band resonance of 2 (out) or 3.5 (in)
- Mid: adjusts up to 15dB of boost/cut at selected mid frequency
- Mid Freq: 6-position rotary switch selects center frequency of the midband EQ stage
- HF Peak: selects HF shelving (out) or peaking (in) mode
- 8K/16K: selects between an 8kHz (out) or 16kHz (in) center or corner frequency for HF band
- HF: adjusts up to 15dB of boost or cut at selected high frequency
The Super Diode-bridge Compressor
Like the Shelford Channel's inductor EQ and transformer-gain microphone preamp, the diode-bridge compressor/limiter is based on the topologies found in vintage Neve designs such as the 2254. It improves, however, on the early designs by the inclusion of full-wave rectification and a bevy of new control features. Although Rupert's vintage diode-bridge compressors were prized for their warm, punchy response, they were somewhat compromised by imprecise controls, attack-time inflexibility, low headroom, and high noise. The Shelford Channel's Super Diode-bridge Compressor delivers the attitude-packed, "in your face" sound of those classics, but with modern precision and flexibility — which makes it ideal on any source. Full Side-chain and stereo Link features are provided.
- Side Chain Insert Jacks (rear-panel): for fine tuning of compressor operation
- Comp In: engages the Channel's compressor-limiter section
- Threshold: sets level where the compressor "kicks in"
- Ratio: sets compression slope from 1.5:1 (minimal) to 8:1 (heavy)
- SC Insert: inserts rear-panel sidechain insert jacks into sidechain signal path
- HPF to S/C: routes highpass filter into the circuit that compressor uses to determine level
- Gain: for adding make-up gain to compensate for level attenuation lost to compression
- Timing: 6-position rotary adjusts attack/release speed of the compressor
- Link: links the sidechain control of multiple units for ganged or stereo operation
- Pre EQ: changes the order of compressor in the circuit chain
- Blend: mixes the dry and compressed signal for handy parallel compression
- Fast: speeds up both attack and release of the selected compressor time constant
Dual-tap transformer output
The Shelford Channel's output stage serves up the inimitable sound of Rupert Neve's classic designs while providing far more tonal versatility. The dual-tap output for the RN2042 square-core output transformer provides both high- and low-headroom outputs without compromising performance. The high-headroom tap takes advantage of the Shelford's higher-voltage design, delivering a pristine sound without non-linear output-stage coloration at high levels. The low-headroom tap, on the other hand, lets you drive the full voltage range of the Channel to accentuate this non-linear harmonic content — without clipping most pro interfaces. For vocals, drums, guitars, bass, and other instruments, this output lets you hit the transformer's sweet spot, which can inject life into a recorded performance in a way that other effects cannot.
The Silk and Texture controls
The Shelford Channel is packing a secret weapon the classics never had: its output transformer features the Silk Red/Blue and Texture controls from the Portico II Series that let you tailor the harmonic content and tonality of the output stage. By engaging these controls and sufficiently driving your output, you can dial in delectable 2nd- and 3rd-order harmonic distortion (that's the good kind) and saturation of the output transformer, imbuing your tracks with juicy rich thickness (think: 1073 on steroids) — with no danger of overloading the output stage. The Silk Red mode emphasizes harmonic content generated by the source's high frequencies; Blue mode, conversely, works off the low frequencies. The Texture knob controls the amount of added harmonic content. Disengage Silk, and your output is pristine and modern, while retaining Rupert's bigger-than-life transformer sonic signature.
The magical sound of Neve
Rupert Neve is an audio legend whose electronics designs defined the golden age of analog. Those of us at Sweetwater 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.
