IsoTek - Sigmas - Power Component in Silver

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 while still 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 20kg. 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. 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.

It is strongly recommended 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 it is advised 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. It is strongly recommended 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.
