The Iso-Max DB-2PX is a stereo 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 flanged steel enclosure for easy mounting in a rack or under a desk. This comes standard with 1/4” inputs and XLR outs along with a removable screw-down barrier strip for installers. Inside, two high-performance Jensen JT-DB-EPC transformers provide galvanic isolation as they passively lower the impedance and perform the balancing. A high 140kohm input impedance reduces loading, enabling low-output instruments such as a vintage Fender® bass to be connected without losing tone. As hi-Z instruments are particularly sensitive to noise, internal Faraday shielding protects against pollution from RF. An external MuMETAL® can further protects the sensitive internal workings to ensure a quiet interference-free performance even when surrounded by magnetic fields from amplifiers, power supplies and stage light dimmers.
