With transformer isolation, switchable attenuation, and a ground lift switch, it delivers a clean, reliable signal path on stage and in the studio—no power required.\u003c\/p\u003e\n\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eConnects unbalanced instrument, line, or speaker signals to balanced inputs\u003c\/li\u003e\n\u003cli\u003eTransformer-isolated XLR output for clean, low-noise signal transfer\u003c\/li\u003e\n\u003cli\u003eParallel 1\/4\" Thru jack lets you feed an onstage amp at the same time\u003c\/li\u003e\n\u003cli\u003eSwitchable attenuation (-20 dB, -40 dB) handles hot line and speaker-level sources\u003c\/li\u003e\n\u003cli\u003eGround lift switch helps eliminate hum and buzz from ground loops\u003c\/li\u003e\n\u003cli\u003ePassive design requires no external power—ideal for active instruments and powered sources\u003c\/li\u003e\n\u003cli\u003eRugged steel enclosure built to withstand demanding live and studio use\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\n\u003ch4\u003ePassive DI for Clean, Balanced Signals\u003c\/h4\u003e\n\n\u003cp\u003eThe PDB converts unbalanced high-impedance signals from instruments, line-level devices, or even speaker outputs into balanced, low-impedance signals. This allows you to run longer cable distances without added noise and to interface easily with professional mic preamps, mixers, and recording systems.\u003c\/p\u003e\n\n\u003ch4\u003eFlexible Connectivity and Level Control\u003c\/h4\u003e\n\n\u003cp\u003eA 1\/4\" TS input feeds both a transformer-isolated XLR output and a parallel 1\/4\" Thru jack, so you can send a clean signal to the front-of-house or recording rig while still driving your stage amp. The switchable attenuation pad (0 dB, -20 dB, -40 dB) lets you match everything from passive instruments to hot line or speaker-level outputs.\u003c\/p\u003e\n\n\u003ch4\u003eReady for the Road\u003c\/h4\u003e\n\n\u003cp\u003eHoused in a tough steel case, the PDB is built to survive the wear and tear of live performance and frequent transport. The passive design means there are no batteries or power supplies to worry about—just plug in, set your pad and ground lift, and you’re ready to go.\u003c\/p\u003e\n\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\n\u003cul\u003e\n\u003cli\u003eActive or Passive: Passive\u003c\/li\u003e\n\u003cli\u003eInputs: 1x 1\/4\" TS\u003c\/li\u003e\n\u003cli\u003eOutputs: 1x XLR; 1x 1\/4\" TS Thru\u003c\/li\u003e\n\u003cli\u003eInput Impedance: 50 kΩ\u003c\/li\u003e\n\u003cli\u003eOutput Impedance: 600 Ω\u003c\/li\u003e\n\u003cli\u003eControls: Attenuator (0 dB, -20 dB, -40 dB); Ground Lift\u003c\/li\u003e\n\u003cli\u003eFrequency Response: 10 Hz – 50 kHz ±0.5 dB @ +4 dBu\u003c\/li\u003e\n\u003cli\u003eDimensions (H x W x D): 3\" x 5\" x 2\" (7.6 cm x 12.7 cm x 5.1 cm)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003cbr\u003e\n\n\n\nManufacturer: Applied research technologies\u003cbr\u003eModel: PDB\u003cbr\u003eSKU: I155512-N-2-WHXE\u003cbr\u003eUPC: 840402011392\u003cbr\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cb\u003eWe are Chuck Levin's Washington Music Center\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eSince 1958, Chuck Levin’s Washington Music Center has been the trusted destination for musicians and audio professionals across Maryland, Virginia, and Washington, D.C.
