Product Introduction
Sigmas has been developed using the award winning technologies from the GII Mini Sub/Vision and the Titan to create a unique high quality full system power conditioning solution. It has been designed to offer the very best performance possible in a single box ‘plug-n-play’ power conditioner. What’s more Sigmas can be used for a complete audio or home theatre system. The performance one can expect from Sigmas is unrivalled at its price point party due to the fact that it harnesses IsoTek’s unique multi award winning ‘Direct Coupled Design’ a critical element in the design of Titan as well as combining this with component from component isolation, key features in GII Mini Sub/Vision and the proprietary ‘Adaptive Gating’ auto sensing features of Nova. Sigmas gives an insight into what can be expected from IsoTek’s truly cutting edge high-end solutions. Within the IsoTek product range the Sigmas sits between the GII Mini Sub/Vision and the high-end Nova & Titan combination.
Features
At the rear of the unit you will note six high quality outlets, 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 high quality filters on each of the outputs and a sophisticated ‘adaptive gating’ system which auto senses the requirement of filtering products connected to the medium current outlets need.
Outputs 1 & 2 (high current) feature the ‘direct coupled design’ concepts first introduced to the field of power conditioning with the Titan. This allows for almost unlimited transient ability, essential for higher power rated products, such as power amplifiers, integrated amplifiers, some ‘tube’ pre-amplifiers, projectors and plasma screens, etc. the remaining four being suitable for all other equipment.
The underside of Sigmas features two Thermo-magnetic fuses, these can be easily accessed from the front panel using the to sculpted cut outs (just below the LEDs) as position indicators. The Sigmas adopts the British electric ‘integrity of fusing’ system. Therefore the (right) 16amp Thermo-magnetic fuse switch must be engaged first, followed by the (left) 6amp. These are located, and can be accessed from the front panel or underside of the unit and eliminate any need to enter the product. IsoTek further enhances the ‘integrity of fusing’ by the use of specialised VDR over voltage protection devices. These are specially selected to offer over voltage safety whilst not effecting audio quality.
All components used within Sigmas are of the highest grade or designed by IsoTek and manufactured to MOD / Aerospace specification and tolerance. All components are under stressed, which gives greater longevity. These high quality parts are then hand soldered (in England) onto the PCB with silver solder. The unit is also fully star earthed.
Placement
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 20 kg. If you have to locate the unit on the floor or in any other location please refer to the safety section of this manual.
Equipment coupling
Once the Sigmas is placed connect the unit to a mains wall socket, with the high quality power cable provided. The unit should then be turned on in the following order. With Sigmas facing you turn on the right thermo-magnetic fuse (located under the chassis), this illuminates the right LED. Then turn on the left thermo-magnetic fuse, again the left LED will turn on. The unit now has full power.
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 Sigmas. Outputs 1 & 2 (marked as high current) 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 rec ommend that the apparatus must be connected to an earthed mains socket outlet.
System integration
Sigmas can be integrated into a complete audio or audio visual system. For two channel applications use the medium current outlets for electronics placed before the power amp in the audio chain. Power amps or active speakers or subwoofers should use the high current outlets. For audio visual applications the same principles apply, however we advise you check the power requirements of projectors, if this exceeds 400W it would be advisable to connect this to one of the high output sockets. We strongly rec ommend 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. All IsoTek cables feature these characteristics.
