Palmer Audio PDI02 DI Box$686.69
Active version for maximum standards of quality. Low-noise, high-impedance, discrete input amp handles even critical input signals such as those from piezo pickups. Transformer has additional Mu-metal shielding.
An integral DC/DC converter permits ungrounded operation when the PDI-02 is powered by phantom power.
