Rupert Neve Shelford 5052: Mic Pre / Inductor EQ - Manual (Page 8)

5052 Features
MIC GAIN
A 12-way precision rotary switch controls gain from 0 to 66 dB in 6 dB steps.
Trim
Continuously variable +/-6 dB level control.
+48V
Engages phantom power on the microphone input.
POLARITY
Push button inverts the polarity of the signal path, and illuminates when engaged.
The symbol “Ø” is often used to denote opposite polarity.
MIC / LINE
Selects between between the Line and Mic inputs on the back panel of the 5052.
EQ IN
Engages all bands of the equalizer except the hpf.
HF
Adjusts up to 15 dB of boost or cut at selected high frequencies.
8K /16K
With the switch out, the center or corner frequency of the high band is 8 kHz. With
the button pressed, the center or corner frequency changes to 16 kHz. Between this
switch and the HI PEAK switch, you have 4 different EQ curves to finesse the high
frequency content.
HI PEAK
When the button is out, the high frequency band operates in shelf mode, boosting or
cutting above the corner frequency at approximately 6 dB/octave. Below the corner
frequency the amount of boost or cut gradually diminishes. With the HI PEAK button
pressed, the high frequency band changes to peak mode with a bell shaped boost
or cut curve. The Peak mode utilizes an inductor and capacitor circuit to create the
bell-shaped curve.
MID FREQ
The MID FREQ rotary switch has 6 positions to select the center frequency of the
mid band EQ stage. This circuit utilizes an inductor and capacitors to shape the EQ
curve, the same way as Rupert Neve’s console designs of the 70’s. The frequencies
chosen are 200 Hz, 350 Hz, 700 Hz, 1.5kHz, 3 kHz and 6 kHz. 200 Hz is
especially useful for cuts on individual tracks within a dense mix.
MID HI Q
The resonance or Q of the mid band at maximum boost is typically 2 when the
