Normal voltage differences in system grounding points between various equipment can cause small AC power currents to flow in the audio signal path. The Sescom SES-XLR-ISO-02 is a balanced XLR audio hum eliminator/isolation transformer unit designed to remove hum and buzz created by these ground loops. Sescom's coupling transformer breaks the inter-equipment ground path rejecting noise in the input circuits while delivering pristine audio signals.
