Builtfor premium sound

ThePortico 5014 uses discrete component circuits, comprising a variable sum anddifference network with level and phase controls, together with other keyfeatures, to affect stereo sources. Intended for recording, mixing andmastering applications, the Portico 5014 differentiates between near field(direct) and far field (ambient) sources and allows the manipulation of therelationship between mono panned images and stereo ambience through the use ofwidth, depth and phase controls. Source material may be further manipulated byinserting external EQ or dynamics processing into the difference channel or byengaging the simple onboard mid-band EQ. Utilizing Mr. Rupert Neve's customtransformer designs, the 5014 is a unique addition to the modern engineer'spalette that brings dimension and life to any recording.

Adjustthe width of any mix

Whenthe width circuit is engaged, the stereo signal is split into a sum anddifference network, allowing the width, depth, insert and EQ controls to beused. The width control enables the user to increase or decrease the width of astereo image (wide/mono) and adjust the amount of ambience inherent in therecording. As the width control is rotated toward wide, the amount ofdifference material is boosted, thus altering the signal that the depth, insertand EQ affect. Conversely, the stereo field is contracted when rotated to mono,and, if the left and right channels are highly coherent (i.e. both channelsinclude closely similar material that is in phase), this mono content isenhanced. If the phase of one of the input channels is then reversed the monocontent may be virtually eliminated. Because the amount of effect the widthcontrol has is entirely dependent on the amount of stereo information in theoriginal source material and the interplay between the 5014's other controls,listening and experimentation are essential for the best results.

Modifythe depth of the mix

Thedepth control of the 5014 adjusts the spatial positioning of elements in thesound stage. A solo instrument or vocal can be placed up front in a mix andsupporting instruments can be pushed back, for example. In many cases, acenter-panned vocalist can be placed forward in a mix or virtually eliminatedwithout adversely affecting the music bed. Used in conjunction, the depth andwidth controls effectively alter the perceived room ambience and dimension.

Differencechannel insert

Thedifference channel insert and EQ offer new opportunities to manipulate stereosignals. In mastering use, lead vocals can be brought up or down in a mix,excessively sibilant overheads can be controlled, and mixes formerly consideredbeyond repair can be saved. By inserting effects such as reverb, additional EQ,compression, or expansion into the difference channel new creative options foraltering ambience and adding movement to the stereo image are available.

DifferenceChannel EQ

Thedifference channel includes a semi-parametric EQ with frequencies ranging from120Hz to 2.4KHz and two selectable Qs that only affect material panned out ofcenter. This can be very useful for eliminating room resonance or addingsparkle to ambient material.
