The AV-HK1X is a rugged product designed for portable use, a mounting bracket is included for fixed installations. Input and output connections are provided on XLR jacks with gold‑plated contacts.

Galvanic isolation between the input and output is provided by a studio quality audio transformer. The AV‑HK1X breaks the "ground loop" connection that can produce hum in a sound system. The input connector shield does provide a radio frequency ground return, thereby preserving system immunity to radio interference.
