The Polarity Checker
This is a unique device for fine-tuning audio installations. It enhances its resolving capabilities by minimizing its residual ground currents.
1) Your audio system is powered by the mains voltage and this means there’s an unavoidable residual hum present at all stages;
2) These residual voltages are of different magnitude (or phase) and will balance out by means of ground currents flowing through the shields of your interconnecting cables;
3) These ground currents share the magnitude levels of the audio signal currents being transferred (micro Amperes). That’s why they interfere and the results are reduced transparency and imaging;
With the POLARITY CHECKER you can fine tune your audio system by dramatically reducing, or even eliminating, those residual ground currents. (Needless to say that this alone will indeed improve your sound…)
