The AH! OffsetKiller functions as an AC-filter, it protects against high voltages peaks, it enhances the performance of your music- and video system (both sound and image!) and next to that it silences the noiselevel of the toroid transformers fed by this powerbar.
All AH! Offset killers will come with 1.8 meter cable.
