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 SeriesTM 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 PorticoTM module.
Don't operate your PorticoTM 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
support@rupertneve.com for resolution.
Rear connecting cables can get very untidy when a number of PorticoTM 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 PorticoTM with the cover removed. The cover provides magnetic
screening from hum and R.F. stray fields.
Power Requirements
Each PorticoTM 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
PorticoTM 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.

In a traditional console large, bi-polar regulated supplies were used, necessarily having a shared
common 0 "ground" wire. Crosstalk between modules resulted, often accompanied by R.F.
interference due to the unbalanced loop "antennas" that were inevitably present. This interference,
in some cases, could actually be heard, but even at low levels below audibility there was a potential
intermodulation with the desired signal. Of course this represented both a quantitative and
subjective intrusion affecting sound quality.
One of the advantages of the PorticoTM method of feeding equipment is that external power units
will work from almost any of the very wide range of mains supply voltages and frequencies that are
found world-wide. While many different types of mains power wall sockets are found in different
countries, PorticoTM 5043 module power units leave the factory with standard US plugs. If
required, any suitable connecting cord may be substituted.
Avoid using a mains power outlet that is on the same circuit as air conditioning of other equipment
that regularly switches on and off. Unplug your PorticoTM power units during a thunder storm or if
it will be unused for a long period.
PorticoTM modules can alternatively be powered from a 12 volt battery, in which case the supplied
AC power unit is not needed. When using a 12 volt battery, choose one that has enough capacity to
power your PorticoTM 5043 - or your complete assembly of PorticoTM modules - for the expected
duration of your session.
THE NEED FOR DYNAMIC CONTROL OF SOUND LEVELS
The dynamic range of sounds we hear around us in normal life greatly exceeds the capability of our
best recording and processing equipment - but even if this were not so, the scale of dynamic range
must be accommodated to the venue in which it is to be reproduced. For example, actual volume
levels of the dance hall would be deafening in a students bedroom. In the same way, late night
listening in a quiet living room demands careful adjustment of dynamic range. In the constantly
changing background noise of a car, drama dialog does not work without constant attention to the
level control. In the field of communications, it is often necessary to ensure that the best possible
signal-to-noise ratio is obtained, in the interest of intelligibility, within the limited performance of,
say, a reporter's recording device.
Digital recorders are unforgiving when overloaded. Overload can be avoided with careful use of
high ratio compression - on the verge of limiting - with careful choice of time constants. A
recording that still sounds "loud" can be produced without non-musical harmonic distortion.
A compressor-limiter is one of the most powerful, yet subjective items in the sound engineer's
armory. Compression should never be obvious to the listener and this needs intuitive and effective
controls on the part of the designer together with considerable skill on the part of the sound
engineer.
