Frequently Asked Questions - PD-3 ART
What type of cartridges does the ART PD-3 support?
The ART PD-3 supports both moving magnet (MM) and moving coil (MC) cartridges. Use the switch on the rear panel to select the appropriate input impedance.
How do I connect the PD-3 to my amplifier?
Connect the RCA or XLR outputs from the PD-3 to a line-level input on your amplifier. For best noise performance, use balanced XLR cables if your amplifier has balanced inputs.
Why is there a hum or buzz from my speakers?
Hum is often caused by a ground loop. Try enabling the ground lift switch on the rear panel. Also ensure all connections are secure and the turntable ground wire is connected.
What is the subsonic filter for?
The subsonic filter removes low-frequency rumble (below 20 Hz) that can cause woofer flutter. It is especially useful when playing warped records or with certain cartridges.
Can I use the PD-3 with a built-in phono stage?
No, the PD-3 is itself a phono preamplifier. Do not connect it to another phono stage; use a line-level input (AUX, CD, etc.) on your receiver or amplifier.
What is the correct gain setting?
Start with the gain knob at minimum. Play a record and gradually increase gain until the volume is comparable to other sources. Avoid setting gain so high that distortion occurs. For MC cartridges, use higher gain settings.
Does the PD-3 require a power supply?
Yes, the PD-3 requires an external 12V DC power supply (included). Plug it into the rear power jack and ensure the power switch is on.
How do I clean the PD-3?
Use a soft, dry cloth to wipe the exterior. Do not use any liquids or abrasive cleaners. Avoid getting dust inside the ventilation slots.
Is the PD-3 rackmountable?
Yes, the PD-3 occupies a standard 1U rack space and includes rack ears for mounting in a 19-inch equipment rack.
What is the warranty period?
ART typically offers a one-year limited warranty from the date of purchase. Register your product on the ART website for warranty service.
