Rupert Neve 5052 Shelford Mic Preamp/Inductor EQ

The Shelford 5052 Mic Preamp/Inductor EQ from Rupert Neve echoes the simple and definitive 1073 feature set with a mic preamp, high pass filter, and 3-band inductor EQ, plus modern capabilities like the variable Silk / Texture control and simultaneous pre / post “tape” operation.

Rupert Neve 5052 Features

• Selects between mic and line inputs
• Continuously variable +/-6 dB level trim control
• Sends the mic preamp signal directly to the EQ when engaged
• A 12-way precision rotary switch controls gain from 0 to 66 dB in 6 dB steps
• 12dB/octave High Pass Filter, variable from 20-250Hz
• +/- 15dB, Shelf or Peak, selectable at 8kHz-16kHz
• +/- 15dB with 6 center frequencies; 200Hz, 350Hz, 700Hz, 1.5kHz, 3kHz and 6kHz, with MID HI Q switch to narrow the bandwidth or increase the Q of the filter.
• +/- 15dB, Shelf or Peak, selectable at 35Hz, 60Hz, 100Hz, or 220Hz.
• +48V engages phantom power on the microphone input
• Push button inverts the polarity of the signal path, and illuminates when engaged. The symbol “Ø” is often used to denote opposite polarity.
