Whirlwind ISO-2 Dual Line-Level Isolator and Balancer

The ISO-2 Dual Line-Level Isolator and Balancer from Whirlwind is a small, rugged 2-channel isolation box and line balancer, for use with audio production in TV, film, and many other applications.

As an isolation unit, it can be used for isolating press and video feeds or on-stage power amps; in broadcast or sound reinforcement applications, it's ideal for eliminating hum and buzz via the ground-lift switch, and dedicated channel 2 polarity reverse switch. The ISO-2 also converts unbalanced lines to balanced lines, facilitating long, noise-free cable runs.
