Vortex Media VTX 1000 - Manual (Page 96)

supplied RCA cables to connect the Vortex to the Auxiliary Input and Output jacks on the Interface Module
are not long enough, we recommend using a audio transformer to interface between the two devices. The
audio transformer will help prevent ground loops that may form over the earth ground if two devices are
connected to wall outlets that are separated from each other (i.e. not in one location such as a power strip).
We recommend using the Jensen ISO-Max DIN-2LO-11FL. This transformer has a terminal (phoenix) strip
for inputs and outputs. Here is a drawing showing how to connect a Vortex EF2280, SoundStation VTX
1000, and Jensen DIN-2LO-11FL transformer together using Input and Output A of the EF2280:
