The Portico 5012 is a dual channel mic pre featuring Rupert Neve’s custom input and output transformer designs. In addition to individually selectable phase, mute, phantom power and a fully sweepable high pass filter, the 5012 incorporates a “Silk” circuit which yields the rich warmth and presence of his renowned classics.

Features

  • Silk that gives a subtle option to enhance sound quality in the direction of a vintage module
  • Level Meter -30 dBu to +22 dBu
  • Mute to cut the output signal post metering and pre Buss Output
  • Variable High Pass Filter to attenuate 20 to 250 Hz
  • Provides 48V phantom power to microphones
  • Buss Output provides an unbalanced and high impedance output intended for use with the Portico Buss Amp/Monitoring modules
  • Polarity invert button
  • Available in Horizontal or Vertical Layouts
  • Rack Mount Kits for Horizontal (5221 and 5211) and Vertical (5285) Available

Microphone Input
The microphone input is balanced but not floating, being a variant of an instrumentation amplifer using a “Transformer-Like-Amplifier” (T.L.A.) configuration with a toroidal Common Mode Rejection Low Pass Filter that excludes frequencies above 150 kHz. The T.L.A. is followed by an actual input transformer permitting a full +25 dBu input signal to be handled at unity gain without an input pad over the whole audio spectrum. This combines the advantages of both an “Electronically Balanced” and true transformer input. When the Phantom voltage is switched off, this input serves as a very high quality line input with an impedance of 10K Ohms.

Low Noise, Low Distortion Operation
Much care was given in designing the 5012 to produce as little noise and non-harmonic distortion as possible. Carefully implemented signal paths and Class A operation are a large part of the 5012′s sweet, whisper-quiet performance.

All Portico modules use input and output transformers and almost entirely discrete component amplifiers. In fact, the Line amplifiers on their own, inserted into the signal chain, are capable of enhancing the sonic quality of many signal sources, especially those of digital origin. These are some of the factors that enable the Portico 5012 to work so unobtrusively within the context of a very high quality audio chain.

Why Transformers?
Incredibly small amounts of musically dissonant odd harmonics can have a disastrous effect on the sound quality. Extraneous noise or interference that finds its way into a signal path seriously impairs performance of the whole chain. Transformers are the ideal solution to solve this problem. The sweet and silky sound of Mr. Neve’s classic designs was achieved with big transistors and large high quality transformers. Rupert Neve Designs’ Portico modules achieve similar quality today without the bulk or the cost.
