The Portico™ 5032 is a single channel Mic Pre/EQ having an independent transformer coupled Line level input for the EQ section. It includes a full-featured Mic Pre identical to the 5012 with the addition of a flexible 3 band Equalizer in the Mr. Rupert Neve tradition. The 5032 is equipped with high and low frequency shelving curves and a Parametric Mid Band covering 80Hz-8kHz in two ranges.
The Rupert Neve Designs 5032 module is a half rack width, 1.75" (1U) module in the now well-known Portico style. The 5032 is ideal for both tracking and mixing applications with selectable mic or line inputs. Both paths have full access to the EQ, phase, silk and mute making it the ideal choice for either standalone operation, or forming the core of a larger mixing system. As with the entire Portico™ range, the construction is a heavy and robust steel shell that provides total magnetic screening and exceptional mechanical stability. The front panel is machined from a solid 1/8-inch aluminum plate with a steel sub panel behind it.
The Portico 5032 module comprises a single microphone pre-amplifier identical with those found in the Portico 5012, and a new 3-band Equalizer.
The output stage is identical with that of the Portico 5012, using single-sided circuitry, driving a carefully configured output transformer that can deliver a full + 25dBu from the balanced and ground-free secondary winding.
The subtleties of audio circuit design as relating to sonic performance are becoming more clearly understood by designers and professional users. For example, it is evident that frequencies above 20 kHz and incredibly small distortion and non-harmonic artifacts, affect the way that humans perceive sound. Specifications and measurements do not fully disclose these sonic qualities that are important to sound engineers and musicians. There is no substitute for hours of patient listening and experimental bench work that results in the sweet and silky sound of my classic designs.
Low Shelf & High Shelf:
The Portico 5032 Equalizer makes use of both a High Frequency and Low Frequency shelving characteristic that provide steeply rising or falling curve shapes. Such curves, when used aggressively, enable second and even third harmonics to be varied in relation to a fundamental, allowing the natural sound of a musical instrument to be varied. Used less aggressively, bands of frequencies above or below the "turnover" frequency can be adjusted to desired levels.
These sections each provide EQ curves that approximate to 6 dB/Octave with a boost or cut of up to 15 dB and a true "Flat" response at the center of the control track. Frequencies chosen for these "turnover" points are the result of critical listening and follow traditional equalizer patterns.
Peak EQ (Mid-Band):
This section provides a very wide range of frequencies in two bands with a powerful "Q" or bandwidth control. The range of boost or cut is +/-15 dB with a true "Flat" response at the center of the control track. The steepness of the actual curve slopes can exceed 6 dB/Octave which results in a powerful "chisel" type of tool. The "Q" control offers completely variable bandwidth, from very narrow to super wide, having a range of "Q" = 0.6 to "Q" = 3.0.
The "base" band covers 80 Hz to 800 Hz, which is important when dealing with the body of a spectrum or for thinning a muddy acoustic environment. A "x10" button multiplies the frequency of the base band by x10 (i.e. it provides continuity from 800 Hz to 8.0 kHz).
