Sigmas is a mid-range, six-outlet mains distribution box from IsoTek, one of the best established names in mains filtration. The case is very solid with a thick alloy front panel. Two circuit breakers, one each for the high current and current portions of the unit, are mounted underneath and are reasonably easily accessible. The IsoTek Systems Sigmas has a marvelous effect on recorded music and is a spectacular piece of equipment. It improves the performance throughout the entire frequency range without upsetting the tonal balance or affecting the tempo.
It is a product that doesn’t compromise at any level and should add a positive and beneficial improvement to systems of modest expense and also dramatically enhance systems that are substantial in price.
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 recommend that a good quality mains cable is used and this cable is consistent throughout your system.
