About Us
Coherence Systems is pleased to introduce the ADD-POWR line of accessory electronics. Our products incorporate specific software algorithms to generate low frequency patterns, amplified and induced into the immediate environment of electrical systems. The Sorcer EM conditioner "re-references" or re-clocks the AC line with low frequency harmonics that neutralize noise. The resulting energy boost to electrical signal strength may be as great as 1 to 2.5 decibel (dB) in signal-to-noise ratio to the audio system. ADD-POWR is Algorithm Digital Defined Power - an energy reference technology developed to enhance the performance of audio/video systems. Nothing more, nothing less.
