DIN-DB - Overview

12:1 Direct Box

The IsoMax DIN-DB is a direct box designed to drive unbalanced instrument signals distances to 100 meters (300') or more without high frequency loss or introducing noise into the signal path. The design begins with a gray molded assembly made from UL94-VO flame retardant Noryl that snaps into place onto a standard 35 mm DIN rail for easy installation in a NEMA enclosure. Connections to and from the module are made via removable screw-down wire terminals. Plug and play easy to use, this passive interface does not require any power to work. Inside is a Jensen high performance transformer providing galvanic isolation as it passively lowers the impedance and performs the balancing. A high 140 k Ohm input impedancem reduces loading, enabling low-output instruments such as a vintage Fender bass to be connected without losing tone. Made for the most demanding professionals, the DIN-DB delivers a ruler flat response from 10 Hz to 100 kHz with less than 2° phase shift. With over +21 dB of signal handling capacity, the DIN-DB gracefully handles extreme signals such, as those produced by digital pianos while producing a warm Bessel response that is often referred to as `vintage' sounding.
