If your LCD is dead, you can use a modern 4x20 character LCD (Common on Amazon/eBay). Here is the "fixed" pinout mapping that the service manual gets wrong:

Check the response across the audio spectrum (20 Hz to 20 kHz, and up to 100 kHz if using the A2-D digital extension) to ensure the analog filters are tracking perfectly linear. Preventative Maintenance Tips However, as these units age, certain component failures

Why? Because the A2 contains proprietary, digitally calibrated components (especially the analog input section and the AES/EBU test circuitry). Neutrik’s official policy was (and remains) .

The Neutrik A2 (Audio Measurement System) is a legendary, high-precision instrument used by audio engineers and bench technicians globally. Known for its reliability and accurate dual-channel analysis, this hardware remains a staple in repair shops. However, because these units are getting older, having a reliable service manual and knowing how to apply fixes is critical to keeping them operational.

However, a common frustration echoes across forums and user groups: the lack of a clear, complete, or error-free service manual. Searching for the "neutrik a2 service manual fixed" yields broken links, scanned PDFs with missing pages, or incorrect calibration data.
