Rupert Neve Portico 5032 - Mic Pre / EQ - Manual (Page 2)

INTRODUCTION
1
Thank you for your purchase of the Portico™ 5032 Microphone Pre-amplifier and Equalizer
module. Everyone at Rupert Neve Designs hope you enjoy using this tool as much as we have
enjoyed designing and building it. Please take note of the following list of safety concerns and
power requirements before the use of this or any Portico™ Series product.
Safety
It’s usual to provide a list of “do’s and don’ts” under this heading but mostly these amount to
common sense issues. However here are some reminders:
The Portico TM 5032 dissipates about 8 watts, which means that it will get warm in use. The heat
generated is radiated through the case work and by convection through the ventilation holes.
Therefore the holes should not be covered or blocked. Portico™ modules may be stacked
horizontally on a desktop or mounted vertically in a rack without heat problems. The anti-slip feet
may be removed while used in a rack, but should be retained for desktop use. To avoid overheating,
Portico™ modules should not be stacked immediately above or adjacent to other equipment that
gets hot. Also bear in mind that other equipment may radiate strong hum fields which could spoil
the performance of your Portico module.
Don’t operate your Portico™ module in or around water! Electronic equipment and liquids are not
good friends. If any liquid is spilled, such as soda, coffee, alcoholic or other drink, the sugars and
acids will have a very detrimental effect. Sugar crystals act like little rectifiers and can produce
noise (crackles, etc.). SWITCH OFF IMMEDIATELY because once current starts to flow the
mixture hardens, can get very hot (burnt toffee!) and cause permanent and costly damage. If it gets
wet and you suspect that good clean water may have gotten in, immediately unplug the unit, and
remove it from the source of water. Please contact support as soon as possible at
[email protected] for resolution.
Don’t be tempted to operate a Portico TM with the cover removed. The cover provides magnetic
screening from hum and R.F. stray fields.
Power Requirements
Each Portico™ 5032 module has two built-in DC to DC converters that provide +/– 17.5 VDC for
the amplifiers and + 48 VDC for microphone Phantom Power. The input is protected from reverse
polarity. The connector center pin must be positive. The converters will work from virtually any
DC supply from 9 to 18 volts that is reasonably “clean”. Avoid using a Power Outlet on the same
circuit as air conditioning or other equipment that regularly switches on and off. Unplug the
Portico™ power unit(s) during a thunder storm or if it will be unused for a long period.
When using a 12-volt battery, choose one that has enough capacity to power your Portico
TM 5032 -
or your complete assembly of Portico™ modules – for the expected duration of your session. For
example, a 48 ampere-hour battery will power 8 Portico™ 5032 modules for 9 hours.
