The Rupert Neve Designs Portico™ 5016 MICROPHONE PRE-AMPLIFIER AND DI MODULE The Rupert Neve Designs 5016 module is a half rack width, 1.75” (1U) module in the now well- known Portico™ style. As with the entire Portico™ range, the construction is a heavy and robust steel shell that provides total magnetic screening and exceptional mechanical stability. - Page 5 When multiple Portico™ modules are configured in a console assembly, mixing busses will be available at many points (beyond the ones traditionally expected), providing enormous flexibility. More detailed descriptions with suggested block and system diagrams are available in the future on the Rupert Neve Designs website at www.rupertneve.com.

Page 6: Design Notes
5016 MIC PRE/DI DESIGN NOTES In former years, before the introduction of solid state amplifiers, transformers were necessary to step up to the very high input impedance of tubes, and to provide a balanced input for the microphone line. An input impedance of 1,000 or 1,200 ohms became established for microphones having a source impedance of 150 or 200 ohms, with connection being made on a twisted twin screened cable (This type of cable, while excellent for low impedance work, has high capacitance... - Page 7 Signals within this band can be attenuated, leaving higher frequencies unaffected.

- Page 9 5016 MIC PRE/DI The D.I. and LINE channel of the Rupert Neve Designs Portico ™ 5016 The D.I. and Line Preamplifier Channel is completely separate from the Microphone Preamplifier Channel housed in this Portico™ 5016 half rack 1U module. The Channels may be used separately without interaction but the real power of the 5016 lies in the Variable Phase feature incorporated into the D.I.

5016 MIC PRE/DI The D.I. and LINE channel Outputs The Output stage is identical with that of the Microphone Preamplifier Channel, driving a carefully configured balanced and floating Output Transformer designed to safely feed long lines with up to 25 dBu. Inter-connection of Professional equipment should always be carried out using balanced lines in order to ensure freedom from interference and hum. -
