Sescom SES-XLR-ISO-01 Single 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-01 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.
Also available in a two channel model (SES-XLR-ISO-2).
