Sescom Two Channel XLR Audio Isolation Transformer

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. Ground-Lift Switching The ground pin of the XLR INPUTS can be "lifted" out of the signal path via a front panel switch to isolate the ground path on the XLR OUTPUTS. This can help eliminate ground loops when mounted to equipment with a different ground reference.
