GROUND LIFT SWITCH
When connecting the XLR Output to other gear, it's possible that it can create a secondary path to
ground, introducing hum to the sound. Using the GND LIFT (Ground Lift) switch disconnects the sec-
ondary ground path, removing the ground loop and the hum that comes from it.

This balanced XLR output provides a low-impedance, high-level output that's ideal for sending to a
mixing console or pro-level audio processors. Its signal is identical to that found at the 1/4" output.
9V POWER INPUT
The Dual Parametric D.I. is designed to be powered by a 9-volt alkaline battery or an AC adapter. This
jack accepts an AC adapter such as Fishman's 910-R or Roland's PSA Series.
Note that using an AC adapter does not recharge a battery inside the Dual Parametric D.I.
BATTERY ACCESS
The battery access door, located on the underside of the Dual Parametric D.I., opens with a fingernail,
guitar pick, or screwdriver. The cover lifts off, exposing the battery compartment. Always use a 9-volt
alkaline battery (Duracell MN1604, Eveready No. 522, or equivalent) for best power; carbon batteries do
not provide reliable enough power and can leak, damaging the Dual Parametric D.I.
When installing a battery, make sure the connectors are aligned correctly in reference to the "+" and "-"
indications shown inside the Dual Parametric D.I. After installing the battery, replace the cover plate.
Never operate the Dual Parametric D.I. without its cover plate in place.
