The IS01 is commonly used in broadcast and live sound applications for isolation purposes, eliminating line noise or converting unbalanced signals to balanced format for long-distance transmission. Built with a high-quality 600:600 isolation transformer, this single-channel isolator and balancer provides completely transparent frequency transmission. Suitable for high-level signals, it can also function directly as an instrument DI box – particularly ideal for acoustic instrument pickups, faithfully reproducing the full frequency response of acoustic instruments.
