[. . . ] P D B P a s s i ve D i r e c t B ox The PDB Passive Direct Box is an accessory for the D. W. [. . . ] The PDB follows the industry standard wiring, with pin 2 "high" or "+" and pin 3 "low" or "-". Pin 1 on the connecting cable should be connected to the cable shield. Internally, pin 1 is connected to the PDB chassis through a RC network when the "GROUND LIFT" switch is in the up position. The proper position of the GROUND LIFT switch must be determined experimentally for each set-up. It may also be necessary to experiment with other "ground" switches on an instrument amp (guitar amp) if one is connected to the AMP jack. In many situations, there will be no difference in the switch position and it can be set either way. The output level of the PDB depends on the level of the signal going into it, but with most pick-up type instruments (electric bass, electric guitar) the output will be around -50 to -30 dBu. With some higher-output instruments (keyboards, amplified bass), the level may be too high for some mic preamps. [. . . ] There is little to go wrong with the PDB, and no routine maintenance is necessary. PSB Passive Direct Box D. W. [. . . ]
