Shelford 5051
Channel Strip
From Rupert Neve Designs:
The 5051 combines a three-band Inductor EQ based on Rupert’s vintage designs with the power & flexibility of the Portico II Compressor. Utilizing a fully-discrete class-A signal path and custom audio transformers and inductors, the 5051 delivers all the performance and musicality expected from a Rupert Neve design.
Inductors are wires wound around a coil that provide a form of frequency-dependant resistance. When they saturate, they bring out beautifully musical harmonics that give your tracks the smooth, polished sound that has made Rupert’s consoles and equipment so desirable for over fifty years. This is what makes them different from capacitor-based EQ designs, which do a great job at surgical equalization. But inductors provide the tone.
While it is certainly possible to create a functioning EQ using off-the-shelf inductors, we choose to use our own custom inductors for the 5051. This attention to detail in controlling variables such as the winding and core materials in relation to the surrounding circuitry allows the 5051 to capture the vitality and personality of Rupert’s classic designs.
