The Rupert Neve Designs Portico™ 5032
MICROPHONE PRE-AMPLIFIER AND EQUALIZER MODULE
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 .20 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 5032 can sit firmly on a bench or desktop on its
detachable rubber feet. Two 5032s can be joined with the optional Horizontal Joining Kit, model
number 5221-RM, and mounted across a standard 19” rack.
When the vertical option is chosen, up to eight 5032s can be mounted in the optional vertical frame,
model number 5285-RM. This leaves a 3” wide space that can be used to house a power supply or
other future modules. 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 eight modules is not fitted into the vertical frame.
MICROPHONE INPUT
The microphone input is balanced but not floating, being a variant of an instrumentation amplifier.
My well-proven “Transformer-Like-Amplifier” (T.L.A.) configuration is used, which includes an
accurate toroidal Common Mode Low Pass Filter that rejects Common Mode signals and excludes
frequencies above 150 kHz. (There are high powered broadcast transmitters at and above this
frequency in several Continents and, even if you can’t hear them, any vestigial intermodulation
products must be excluded!)
The Common Mode Coil effectively takes the place of a traditional input transformer at high
frequencies and is able to handle low frequencies over a wide range of levels with virtually no
additional distortion.
The T.L.A. is followed by an actual input transformer. This imparts galvanic signal isolation and
the sweetness for which good transformers are known. The transformer works at an approximately
constant level with more predictable performance.
When the Mic Gain switch and Trim controls are set to Unity (0 dB) the Portico™ 5032
microphone pre-amplifier can handle a balanced input signal of more than +20 dBu without an
input attenuator pad! This is a unique feature that enables this input to double as an additional line
input.
