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.
