In 2006, we launched our very first APx analyzer: the APx585. To celebrate 20 years of precision audio testing, we are on a global hunt for the oldest operational, in-service APx unit still hard at work.
If your unit is crowned the oldest, we will trade it—at zero cost to you—for a brand-new APx analyzer of your choice. Are you sitting on a piece of audio testing history? Find out if you qualify and enter below.
Is Your Unit Eligible?
To qualify for the contest, your analyzer must meet all of the following criteria:
• The unit must be an APx model (of any kind).
• The unit must power on and perform to specification.
• The unit must be in active use (daily or at least weekly) in your lab, test bench, or production line.
• The unit must be currently owned by you or your company.
You and your company must also be willing to have your name used in association with Audio Precision and our promotion of the 20th anniversary of the APx500 family of audio analyzers.
Submission Deadline
All photos and entry details must be submitted by November 10, 2026 to be eligible for the contest.
