The Rupert Neve Designs Portico 5032 is a single channel microphone preamp and equalizer with an independent transformer coupled Line level input for the EQ section. The Portico Series 5032 includes a full-featured mic pre identical to the Neve 5012 with the addition of a flexible 3 band equalizer in the Rupert Neve tradition. The Neve Portico 5032 is equipped with high and low frequency shelving curves and a parametric mid band covering 80Hz-8kHz in 2 ranges.The Neve 5032 module is a half rack width, 1.75 (1U) module in the now well-known Portico style. The 5032 mic pre and EQ 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 the Neve Portico 5032 the ideal choice for either standalone operation, or to form the core of a larger mixing system. As with the entire Portico Series, the 5032's boasts 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.Alternative front panel layouts are available providing a choice of vertical or horizontal mounting. When the horizontal front panel is chosen, a single Portico 5032 can sit firmly on a bench or desktop on its detachable rubber feet. 2 Neve 5032s can be joined with the optional Horizontal Joining Kit (Model # 5221-RM) and mounted across a standard 19 rack. When the vertical option is chosen, up to 8 of the Portico 5032s can be mounted in the optional Vertical Frame. This leaves a 3 wide space that can be used to house a power supply or monitor unit. The vertical frame assembly is designed for rack mounting and includes basic rear cable management. Blank panels are available to fill any unused spaces when the full complement of 8 modules is not fitted into the optional vertical frame.The Portico 5032 module comprises a single microphone pre-amplifier identical with those found in the Neve Designs 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 EQUALIZER 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 and 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 &plusmin;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).MIC/LINE INPUTS: Sepreate mic and line inputs may be selected. With both inputs, phase, silk, hpf, and the 3 bands of eq are available for use.LOW SHELF: Fixed 150Hz frequency with continously variable gain of +/-15dBMID PARAMETRIC BAND: Continuously variable frequency in two ranges from 80 Hz to 800 Hz and 800Hz to 8KHz, selected with the 10X push button; continuously variable Q; continuously variable gain of +/- 15 dBHIGH SHELF: Fixed 8Khz and 16Khz frequencies selected with the 8K/16K push button; continuously variable gain of +/- 15 dBEQ IN: Engages all three bands of EQSILK: Much could be written about this feature, suffice to say, that it gives a subtle option to enhance sound quality in the direction of vintage modules. The Silk button reduces negative feedback and adjusts the frequency spectrum to provide a very sweet and musical performance. We suggest you try it and make your own judgment.LEVEL METER: -30 dBu to +22 dBu With reference to the outputMUTE: Cuts of the output signal post metering and pre Buss Output. Be sure to mute the outputs before engaging phantom power.HIGH PASS FILTER: The High pass filter is a valuable aid in any signal chain but particularly so in a microphone preamplifier. Signals between 20 and 250 Hz can be attenuated, leaving the range above this unaffected. This gets rid of building rumble, air handling motor hum etc.PHANTOM POWER: Provides 48V phantom power to microphonesBUSS OUTPUT: The To Buss output is unbalanced and has a high impedance output. It is intended for use with the Portico Buss Amp/Monitoring modules. A TRS patch cord is used to connect the 5012 Buss output to one of these bussing modules. The Monitor connection is derived pre mute on the 5012 and will produce a signal at the output of the buss modules that is equal in level to that at the 5012 output. The Monitor output cannot be used for any other purpose.PHASE INVERTS: Flips the phase of an incoming source 180 degrees
