Neutrik A2 Service Manual Fixed: The Ultimate Guide to Resolving Your Test & Measurement Headaches

If you are an audio engineer, systems integrator, or rental house technician, you know the name Neutrik. Famous for the ubiquitous XLR connector, Neutrik also produces high-end test and measurement equipment. The Neutrik A2 is their flagship audio and cable tester—an indispensable field tool for diagnosing XLR, SpeakON, RJ45, and other connections.

Section 4: Calibration – The "Fixed" Procedure

You cannot calibrate the A2 without a low-distortion oscillator (0.001% THD) and a true RMS meter. The manual’s step using a Fluke 8506A is obsolete. neutrik a2 service manual fixed

First, reflow the solder joints on the XLR input jacks – they crack over time.
If that fails, replace the digital input transformer (check the part number on the transformer near the AES input). A compatible replacement is the Scientific Conversion SC961-05 or similar 1:1 transformer.
