1. Introduction
DAC-80 is designed to remove hum and buzz created by ground loops. Normal
voltage differences in the system grounding points between different pieces of
equipment cause small AC power currents to flow in the shield of audio cables.
Capacitance between a power transformer’s primary and secondary windings
introduce signals to the circuit ground which will also create small current flows
in the cable shield. Either of these problems will create hum in audio signals.
DAC-80 breaks the inter-equipment ground path and greatly increases the
rejection in the input circuits while remaining transparent to the audio signal.
