The company
The principles
The execution
IsoTek was formed in July 2001 with the vision to create high quality
mains power distribution units that moved beyond current
conventions. Through careful market analysis and extensive research
we were able to launch products that moved power distribution
forward to be recognised as an integral part of any audio or home
theatre system. Our products continue to lead the way in power
management systems, our latest GII range galvanises our commitment
to pursue excellence at every level.
We believe all products benefit from their own clean power supply,
therefore we advocated the concept of using (smaller) individual filters
on each component, with these being specifically designed for their
purpose, this dramatically reduces and stops component cross
contamination and dispels the belief that one size fits all. Every single
component used in our designs is extensively tested for quality,
reliability and purpose. Our circuit designs are extensively ‘field’ tested
before coming to market so we can guarantee the widest compatibility
with third party products.
Within the market of premium audio it is vital to offer exceptional
performance and value for money. Products must be made to the
highest of standards, be reliable and attractive. A manufacturer must
offer exceptional service, dealer training, support and undertake the
very best in promotion design and literature. If all these elements are in
place customers should experience excellence at every stage. Our
continual quest is to meet these challenges.
All of our products are professionally designed, manufactured and
hand built in the UK, with deep consideration given to both style,
functionality, performance and value for money.

Overview
Features
Thank you for purchasing our Mini Sub or Vision.
The Mini Sub & Vision is our award winning component from
component mains power filter and distribution unit. It was designed to
be a very rewarding single box ‘plug-n-play’ solution for a complete
audio or home theatre system. The Mini Sub & Vision offer astounding
value for money and gives a taste of what our truly high-end solutions
offer. Within our product range the Mini Sub & Vision sit between the
Solus and high-end Nova.
At the rear of the unit you will note six high quality outlet, these are
individually filtered to stop components ‘talking’ to each other or
corrupting the clean supply provided by the unit. This is achieved by a
series of delta filters on the outputs and a sophisticated notch filter
which was inspired by work in cryogenics, and harnesses the
technique used for the switching of cryogenic coils.
Outputs 1 & 2 have been given a higher power rating and should be
used for high current devices, for example power amplifiers, integrated
amplifiers, some ‘tube’ pre-amplifiers, projectors and plasma screens
etc. The remaining four are suitable for all other equipment.
Mini Sub & Vision features enhanced protection through stabilising the
units voltage and giving it a very large absorption ability, this is
extremely important in today’s society where dangerous power surges
can damage sensitive audio equipment.
All fusing is external, this eliminates any need to enter the product. The
unit is so safe that even if the mains are wired incorrectly in the rest of
the house or environment that the product is used, the unit will correct
the problem sonically.
All components are of the highest grade and are under stressed, this
gives greater longevity. These are hand soldered onto a PCB with silver

solder, the large PCB also features a ground plane upper surface
acting as a very high grade common mode filter across the whole
board, this allows the unit to act as a true faraday cadge, protecting
itself from RFI and other components from the job it performs. The unit
is also fully star earthed.
Weight loading
!
20Kg
Safety
In the interest of safety the unit should be placed upon its own
dedicated shelf on an audio grade equipment rack. The unit may be
placed on top of or under other pieces of equipment, do not exceed a
maximum weight loading of 20kg.
Areas where ‘tube’ amplifiers are present should not exceed 25
degrees. If you are positioning the Mini Sub or Vision in the close
proximity of such a device please be aware of this factor.
If you have to locate the unit on the floor we strongly recommend you
do not place the unit near heat sources, such as radiators or air ducts.
Good air circulation is essential to prevent heat build up within the
chassis. Do not place the Mini Sub or Vision on a soft surface, for
example a rug or carpet, which could block the ventilation intakes on
the underside of the unit. Do not let any liquids spill onto or objects fall
into the chassis. Should either of these events happen immediately
switch off the unit at the wall socket, wait for at least one minute,
unplug all other cables and return it to your authorised IsoTek dealer
for a full service.

System integration
Ideally the unit should be placed upon its own dedicated shelf of an
audio grade equipment rack. If this is not possible the unit may be
placed on top of or under other pieces of equipment to a maximum
weight limit of 20kg. Due to the products careful screening by way of a
large ground plan within the unit, no adverse effects should be caused
by this placement. If you have to locate the unit on the floor or in any
other location please refer to the safety section of this manual.
Once the Mini Sub or Vision is placed connect the unit to a mains wall
socket, we recommend that a good quality cable is used and that the
wall socket is also unswitched. Turn off all equipment you wish to have
a clean mains supply, unplug the cables relating to these from the wall
socket or redundant distribution block you may have been using and
plug these into the rear sockets of the Mini Sub or Vision. Outputs 1 &
2 (marked with a red dot) have been given a higher power rating and
should be used for high current devices, for example power amplifiers,
integrated amplifiers, projectors and plasma screens etc. The
remaining four are suitable for all other equipment.
We strongly recommend that a good quality mains cable is used and
this cable is consistent throughout your system. Look for a cable with
good conductors, for example oxygen free copper, this cable should
also have a high degree of shielding from RFI.

D. Troubleshooting
Fuse location
Fuse holder of IEC inlet
Fuse in UK three pin plug
Fault finding
The front panel LED is not lit and the unit gives no power.
Check that the mains inlet fuse is intact, this will be located in the
drawer of the IEC socket at the rear of the unit on the left hand
side. If there is not a fuse located or you have used up your supply
please contact us on 01635 291357 or email
support@isoteksystems.com so that we can forward you a free
replacement.
Check that the mains cable is securely plugged into the unit and
the wall socket.
Check the fuse within the plug is intact.
On rare occasions the fuse at the main distribution fuse box may
also need to be checked.
The Mini Sub & Vision, in its GII form remains safe even if mains
polarity is reversed. However, we would strongly recommend a simple
check of mains polarity. Your local IsoTek authorised dealer will be able
to supply a product through us to help you establish this. Mains
polarity is of particular importance in markets where European Shuko
plugs are used.

Upgrades
We strongly recommend that a good quality mains cable is used and
this cable is consistent throughout your system. Look for a cable with
good conductors, for example OFC (oxygen free copper). This cable
should also have a high degree of shielding from RFI. Outside of the
UK it is not uncommon for cables of 6Amps current capability to be
connected to a 20Amp outlet. In practice this seems to be a safe
arrangement. However we strongly recommend a cable of the full
20Amps carrying capability be used, with a minimum 1.5mm squared.
IsoTek produce their own cable in standard 1.5M lengths. All cables
feature high quality connectors, OFC conductors and fully earth
shielded. This removes any chance of RFI entering the cable. Four
versions are available: Premium and Elite as well as higher current
Optimum. IsoTek 24ct high grade connectors are used in the Elite,
Optimum designs these can also be purchased individually.
Our GII range of products work well with all third party equipment
including varying cable technologies. If ‘off-the-shelf’ mains cables are
used we recommend the use of Ferrite rings to reduce RFI. We also
recommend the use of contact conditioners, for example Blue
Horizon’s Clean-IT (www.bluehorizonideas.com). Isolation devices, feet
and cones may also be used. We recommend Clearlight Audio RDC
products which we use on our higher end products, for example, Titan.
It is possible to increase the performance of the Mini Sub through ideal
location and product placement, the use of isolation devices and
contact conditioners for example. The Mini Sub can also be used to
run front-end only equipment with one of our dedicated power
amplifier products. For example, the introduction of a Titan for that
specific purpose. Full details can be found from your local authorised
IsoTek dealer or on our web site www.isoteksystems.com
