ART PD3 1000 Professional Delay System - Multi-Tap Digital Delay Line - 1U Rackmount - Good Condition

Up for sale is a used ART (Applied Research and Technology) PD3 1000 Professional Delay System. Engineered in the USA to demanding professional touring and commercial installation standards, this 1U rackmount unit is a highly respected utility tool built for ultra-precise time alignment. The PD3 1000 is a mono-input, 3-output (tri-tap) high-performance digital delay line. It is highly sought after by pro-audio technicians for time-synchronizing distributed speaker arrays in large commercial venues, aligning satellite delay towers at music festivals, or ensuring phase-linear time alignment in broadcast, television engineering, and multi-room facility distribution systems. Condition Notes: This unit is in Good Used Condition and is fully operational. Performance: All three discrete output signal lines adjust cleanly. The front-panel input/output attenuators turn smoothly, and the signal/clip LED level meters respond accurately. Cosmetics: Shows typical cosmetic signs of standard pro-audio rack use over the years. The front faceplate looks very presentable, with minor edge scuffs, light surface scratches, and standard rack-rash on the top and bottom of the metal housing from installation (please see all detailed photos). The PD3 1000 Advantage (Expanded Memory): While the standard PD3 caps out at 255ms, this specialized PD3 1000 model multiplies the delay capability by four, providing up to a full 1,000 milliseconds (1 second) of total delay time. In normal operation, each of the three outputs (A, B, and C) can be individually dialed in using the front-panel binary DIP switches in precise 4ms increments. For specialized, near-field driver alignment within a speaker cabinet array, an internal short-delay jumper switch flips the unit into micro-alignment mode, scaling the steps down to ultra-fine 125 microsecond ($\mu s$) intervals. Key Features & Specs: Brand: ART (Applied Research and Technology) Model: PD3 1000 Professional Delay System Form Factor: 1U Standard 19" Rackmount Chassis Configuration: 1-Input / 3-Output Tri-Tap Matrix Audio Fidelity: High-end 16-bit linear D/A conversion running at a high 64kHz sample rate, providing a fully flat 20Hz to 20kHz bandwidth. Maximum Delay Time: 1,000 milliseconds (1 second) Precision Increments: 4ms steps (Normal Mode) or 125$\mu s$ steps (Short Delay Mode) Stability: Crystal-controlled internal timebase ensures absolute long-term accuracy with zero drift. Rear I/O Matrix: Features both active balanced 1/4" TRS jacks and traditional commercial Barrier Strip terminals for universal connectivity. Power Supply: Integrated internal transformer utilizing a standard attached AC power cord. _______________ 🎵 Welcome to The Muzic Store INC – Dobbs Ferry, New York! 🎵__________________ _____________________ Store Hours: Monday–Friday, 11 AM – 6 PM________________________________ If you ever need something extra included with your purchase, please let us know before shipping — we’re always happy to help!
