The DI performs level matching, balancing, and either active buffering or passive impedance matching/impedance bridging to minimize noise, distortion, and ground loops for instruments such as electric bass, acoustic guitar, keyboard and iPods, and other music devices.
Genuine earth isolation. Extremely high input impedance. Low noise and distortion. Transformer balanced output. This Active Direct Inject (D.I.) Box is designed for optimum performance with any musical instrument signal source, especially in electrically hostile environments such as live performance venues using light dimmers.
