While the ADDAC710 is designed to protect what goes out of your modular, the ADDAC711 protects what comes in. Using a dual channel Isolated DI box, the ADDAC710 keeps your modular free of undesired noisy interferences by providing galvanic electrical isolation from external sources while preventing ground loop induced hum. Similar to the ADDAC710 at the output stage, the ADDAC711 also uses an impedance matching transformer that operates in the 20 Hz to 20 KHz range, while providing two fully balanced outputs (via XLR connectors).
