The Whirlwind ISO-2 is a small, rugged 2-channel isolation box and line balancer. As an isolation unit, it may be used for isolating press and video feeds, or on-stage power amps, in broadcast or sound reinforcemnt applications, eliminating hum and buzz via ground lift switched and a dedicated channel 2 polarity reverse switch.
The ISO-2 also converts unbalanced lines from CD players, tape decks and other like devices, to balanced lines, facilitating long, noise-free cable runs.
