Distortion Analyzer


Audio engineers may choose between a range of instruments providing distortion measurements. 

At a Glance

  • THD, THD+N, k2 - k35
  • Comprehensive or basic distortion testing
  • Audible monitoring of residual distortion

Detailed Analysis with FX100 Audio Analyzer

The Flexus FX100 supports the simultaneous measurement of Total Harmonic Distortion with or without Noise, as well as the upper harmonics k2 - k35. Furthermore, a user-defined selection of harmonics may be summed together, and individual Pass/Fail limits may be applied. The distortion measurements are available in the Meter, GlideSweep or StepSweep mode.

Example of GlideSweep THD:

Basic Distortion Measurement with XL2 Analyzer

With the balanced XLR and unbalanced RCA inputs, the XL2 is a comprehensive audio analyzer. It simultaneously measures level, distortion (THD+N) and frequency. The internal loudspeaker or headphone is used for audible monitoring of the test signal or the residual distortion. The optimized low-distortion and low-noise design allow level measurements down to -112 dBu and residual distortions typically lower than -100 dB, which is unmatched in handheld instruments.

Basic Distortion Measurement with Minilyzer ML1

Minilyzer ML1 screen THDN
The Minilyzer ML1 supports Total Harmonic Distortion plus Noise (THD+N) and 2nd to 5th harmonic distortion measurements, expressed in dB or %. Both the input level and frequency measurements run in parallel, while the balance indicator detects defective cables.
