GII Models




You will find here manuals from our GII series models that have been introduced to the market in the early 2000s.

IsoTek was driven by the desire to make something better, to design mains conditioning components that improve sonic definition and detail without the dynamic restrictions commonly introduced by products already on the market.

Many of the GII models are still being used and protect the systems from surges and acoustically upgrade the audio-, or audio-video system in which these are connected.

Several of the multi award-winning GII models have been updated to EVO3 over time.
