Rupert Neve Portico 5043 - Compressor / Limiter Duo - Manual (Page 2)

INTRODUCTION
1
Thank you for your purchase of the 5043 Duo Compressor Limiter. 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 TM product.
Safety
It’s usual to provide a list of “do’s and dont’s” under this heading but mostly these amount to
common sense issues. However here are some reminders:
The Portico 5043 dissipates about 9 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 desk top or 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. Porticos 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 TM module.
Don't operate your Portico TM module in or around water! Electronic equipment and liquids are
not good friends. If any liquid was 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.
Rear connecting cables can get very untidy when a number of Portico TM modules are stacked on
your bench. It’s a good idea to use cable ties to bunch the cords into a tidy form.
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 TM 5043 module has a high quality DC to DC converter that provides carefully
stabilized and filtered +/– 17.5 VDC for the amplifiers. The meticulous audio quality of your
Portico TM is protected by the internal converter and does not depend primarily on the
eveternal mains power supply. The input is protected from reverse polarity. The connector center
pin must be positive.
The converters will work from any DC supply from 9 to 18 volts that is reasonably “clean”. The
power supply normally provided with the 5043 is a high quality, robust, and very reliable switched
mode power supply. There are no special requirements for the Portico TM low voltage units other
than that they must be of good quality, reliable, and able to supply enough current for the number of
modules in use.
The great advantage of this system is that there are no common D.C. supply rails that are
directly shared by other modules.
