Please note, than when running composite video cables you may wish to plan to include an
ISO-V Video Isolation Amplifier. When running long line-level audio cable you may wish to
plan for an ISO-2 Line Level Isolation Amplifier or the combination set of XLRX-1 and XLRR-
1 Unbalanced to Balanced and Balanced to Unbalanced Line Level Convertors. The ISO-2 may
assist in removing ground-loop hums induced on the audio cable. The XLRX-1 and XLRR-1
along with quality audio cable will provide the very best answer for system's where ground
loop hums may pose a problem. Please note, that no matter what devices you choose to use
when running long cable runs, their effectiveness will be minimized when using inadequate
cables. The best solution for potential ground loop problems is great wire which is run as far
away from high-voltage type wires as possible (always cross voltage wires perpendicularly).
