Rupert Neve Designs 5052 - Microphone Preamplifier and Inductor EQ

The Rupert Neve Designs Shelford 5052 - Microphone Preamplifier and Inductor EQ is part of Rupert Neve's Shelford series of modules designed to be rack mounted in a 500 series "lunchbox" rack and used for studio recording. The unit combines elements of the iconic Neve 1073 with a vertically-oriented mic pre, a high pass filter, and a 3-band inductor based equalizer. The device goes further with the incorporation of some of Neve's more recent innovations such as the variable silk texture control from the Portico II series as well as simultaneous pre- and post-tape operation.

The preamplifier uses a discrete class-A ±24V topology with custom-wound square-core transformers and inductors to deliver the classic Neve sound with modern performance. The preamp section includes selectable +48V phantom power for operation with condenser microphones, a polarity reverse switch, and a sweepable 20 to 250 Hz high pass filter. For changing the tonality of the sound, the pre section also includes the Portico II Silk Red/Blue and Texture controls that allow you overdrive the output of the unit with up to 5% Total Harmonic Distortion (THD) to add weight and warmth to the signal with 2nd and 3rd order harmonicas.

The transformer-coupled output of the unit can be fed into a tape machine or DAW directly while still allowing you to use the EQ and Silk/Texture controls within a dedicated analog mix path. You can also use the output to insert a separate compressor between the pre and the EQ or allow the 5052 to work with two separate sources.

The EQ section of the unit combines design elements of the Neve 1064 for rich resonant bass with the option of also using the LF band as a shelf or peak filter. The mid-range EQ is inspired by the Neve 1073 for sweetening vocals and bringing lead instruments forward into the mix. The mid band features a proportional "Q" response that can be used for minimizing problematic frequencies. The HF band of the EQ combines the inductor circuitry of the 1073 with capacitor-based topologies from more modern designs. Each section of the EQ uses low-feedback class-A discrete electronics to prevent unwanted harshness or artifacts from influencing your mix.

Power is supplied to the unit on ±24V rails from an external DC power supply using a 4-pin connection. This can be provided by either the RND 5-way brick power supply or the RND 24-way 2U rack-mount power supply. For I/O the unit includes three XLR-3F connections for Mic In, Line In, and EQ In. For outputs it includes two XLR-3M connections for Mic Out and Main Out. The "half-rack" unit can be mounted in a Rupert Neve Designs 2-way vertical unit, 4-way vertical unit, an existing 9-way rack, or the RND 5088 penthouse.
