Turn a good mix into a great mix with this subtle, but powerful dynamic stereo field processor.
The Rupert Neve Designs Portico 5014 Stereo Field Editor introduces an innovative application of well-known
techniques that redefines the boundaries and limitations of traditional 2-channel stereo recording and playback. Operating
entirely in the analogue domain, the Portico 5014 uses discrete component circuits, comprising a variable sum and difference
network with level and phase controls, together with other key features, to affect stereo sources.
Intended for recording,
mixing and mastering applications, the Neve Portico 5014 differentiates between near field (direct) and far field (ambient)
sources and allows the manipulation of the relationship between mono panned images and stereo ambience through the use of
width, depth and phase controls. Source material may be further manipulated by inserting external EQ or dynamics processing
into the difference channel or by engaging the simple onboard mid-band EQ.
Designed with the same half-rack dimensions
as the rest of the Neve Designs Portico Series, available in horizontal or vertical formats, and utilizing Mr. Rupert Neve's
custom transformer designs, the 5014 Stereo Field Editor is a unique addition to the modern audio engineer's palette that
brings dimension and life to any recording.
Controls:
Width
When the width circuit is engaged, the stereo signal is split into a sum and difference network, allowing the width, depth,
insert and EQ controls to be used. The width control enables the user to increase or decrease the width of a stereo image
(wide/mono) and adjust the amount of ambience inherent in the recording. As the width control is rotated toward wide, the
amount of difference material is boosted, thus altering the signal that the depth, insert and 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 channels include
closely similar material that is in phase), this mono content is enhanced. If the phase of one of the input channels is then
reversed the mono content may be virtually eliminated. Because the amount of effect the width control has is entirely dependent
on the amount of stereo information in the original source material and the interplay between the 5014's other controls, listening
and experimentation are essential for the best results.
Depth
The depth control of the Portico 5014 adjusts the spatial positioning of elements in the sound stage. A solo instrument or
vocal can be placed up front in a mix and supporting instruments can be pushed back, for example. In many cases, a center-panned
vocalist can be placed forward in a mix or virtually eliminated without adversely affecting the music bed. Used in conjunction,
the depth and width controls effectively alter the perceived room ambience and dimension.
Difference Channel Insert
The difference channel insert and EQ offer new opportunities to manipulate stereo signals. In mastering use, lead vocals can
be brought up or down in a mix, excessively sibilant overheads can be controlled, and mixes formerly considered beyond repair
can be saved. By inserting effects such as reverb, additional EQ, compression, or expansion into the difference channel new
creative options for altering ambience and adding movement to the stereo image are available.
Difference Channel EQ
The difference channel includes a semi-parametric EQ with frequencies ranging from 120Hz to 2.4KHz and two selectable Qs that
only affect material panned out of center. This can be very useful for eliminating room resonance or adding sparkle to ambient
material.
WIDTH
Opens the stereo field when the controls are set to wide, boosting the level of difference material. It contracts the stereo
field when set to mono, reducing the level of difference material.
DEPTH
Moves the perceived stereo image closer or further away. When used with width, the perceived ambience, room and distance of
a recording can be controlled. insert (difference signal) Available only in the difference channel (any material panned out
of center).
TRIM
High performance transformer-coupled line amps provide independent level control with +/-10dB gain for each channel.
INSERT
Engages a balanced send and return on the difference circuit
PHASE
Inverts the phase of the selected channel by 180 degrees.
DIFFERENCE EQ
Semi-parametric, with a frequency range of 120Hz to 2.4KkHz, +/-15 dB gain, with two Q settings.
METERS
8-segment LED peak meters provide separate left and right level monitoring.
Rackmounting Porticos: If
you'd like to rackmount a single Portico, Neve offers the Half Rack Joining Kit (see #482654). Or to rackmount two Portico
units, Neve offers its Horizontal Joining Kit (see #482653). Another option for mounting single half rack units is the Raxxess
Universal Rack Shelf (see #421642).
