Description
Hum due to ground loops is a common occurrence in pro audio systems. The Apex AHK1 Hum Killer transformer-isolates any two AC-powered devices` line-level inputs (or outputs) from the AC ground reference that the devices have established (and thus defeats the loop). The AHK1 is a passive device requiring neither batteries nor connection to the AC power, and can be used on either balanced or unbalanced signals.
