A Whole New Vintage – Over fifty years in the making, the Shelford Channel is the definitive evolution of the original technologies in Rupert’s classic console modules like the 1073, 1064, 1081 & 2254, thoughtfully advanced and refined for the 21st century studio. The Shelford Channel is built around Rupert Neve’s first new transformer-gain, class-A microphone preamplifier in over 40 years, the “best-of-the-classics” inductor EQ section from the Shelford 5052, a tone-packed Diode bridge compressor, the analog power of variable Silk saturation, a new dual-tap transformer output stage for maintaining headroom or allowing the full driving of the Channel without clipping standard converters, and twice the operating voltage of vintage designs.

With richly-colored tonal options for making bold statements with your music, and precisely-engineered detented controls for recall, the vintage-inspired Shelford Channel maintains the soul of Rupert’s classic designs with new levels of versatility, delivering what can only be described as the combined essence of fifty years of Rupert Neve’s designs

Transformer Gain Mic Input
Like Rupert’s classic designs, the Shelford Channel’s mic input uses direct transformer coupling with 15dB of gain in the transformer itself. This extremely sensitive design utilizes the new RN4012 transformer
Direct Input
The Hi-Z front panel input uses the same discrete class-A FET with transformer topology as the Rupert Neve Designs RNDI, but it utilizes the new RN4012 input transformer directly into the microphone preamp for gain.
Dual Tap Output
The dual-tap output for the Channel’s RN2042 square-core output transformer creates both high and low headroom outputs without compromising the channel’s performance. The high headroom tap is designed capture a more pristine sound at high levels
Silk & Texture
Another advantage of the Shelford Channels’ transformer balanced output stage versus vintage modules is the addition of the variable Silk & Texture circuitry, which allows complete control over the harmonic content and saturation of the output transformer. With Silk disengaged, the output is modern and pristine, yet still retains Rupert’s signature larger-than-life transformer sound. When engaged, the harmonic content – predominantly 2nd order and 3rd order with no high order distortion
MIC/DI/LINE
Switches between microphone/direct injection input (button out) or line input (button in).
Gnd Lift
This switch separates the direct connection from audio signal ground to chassis earth.
Signal Present LED
This LED is dual function. When green, it indicates “Signal Presence” (a signal level of -20dBu). When red, it indicates 2-3dB below input stage clipping of the Mic/Line stage (+23 dBu while the pre actually clips at +25 dBu).
Mic Gain
This 12-way precision rotary switch controls gain from 0 to 66 dB in 6 dB steps.
Trim
This rotary switch provides further continuous gain adjustment over a range of +/– 6 dB.
48V
This push button switch engages phantom power on the microphone input. Please remember to press the mute button or turn down monitors and headphone sends or the channel the Shelford Channel is plugged into before toggling “+48” (and be especially cautious if you use pre-fader aux sends for headphones).
Phase
This push button switch inverts the polarity of the signal path. It illuminates when engaged. (The symbol “Ø” is often used to denote opposite polarity.)
HPF
The HPF switch engages a 12dB per octave high pass filter. The HPF potentiometer is variable from 20Hz to 250Hz, and can be used to filter out unwanted low frequencies, or in conjunction with the EQ to help shape source material.
EQ In
This swtich engages all EQ frequency bands except the HPF.
