Datavideo DAC-80

Datavideo DAC-80 removes hum and buzz from audio lines caused by ground loops. Simply connect the input and output XLR cables to eliminate audio noise caused by ground loops. The device features low signal loss and low distortion, and is completely passive, no power is required for it to function. The DAC-80 is compatible with the optional RMK-2 holder, and the optional MB-5 velcro strap adapter.

The 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.
