Performance Verification  

Every product that leaves our shop is fully tested and verified that its performance meets our standards.


Not only do we test each product, we also supply the results inside the box as a verified test report.  Our customers can be confident that our shipped products meet our demanding standards. If a product fails our testing, it is pulled from production to be debugged and reworked or rebuilt.

Example Test Report

Common tests include:

  • Frequency response and bandwidth plots

  • Channel Gain

  • Channel Balance

  • Distortion

  • Noise and SNR

We also have a standard of testing the bandwidth and total harmonic distortion of our power amplifiers at both 1-Watt and at full rated output power across the entire bandwidth of the amplifier.

Most of our tests are performed on an Audio Precision Analyzer. 


For decades, AP's test hardware and software has been widely recognized as the gold standard for audio performance verification and product bench-marking.

You can be confident that our products perform as stated in the test report included with every product.
