A New QC Module - Multi-Tone Distortion

New module: MTD

In order to provide dedicated tools for standard-compliant audio testing, KLIPPEL released a new software module: QC Multi-tone Distortion (MTD) for efficient end-of-line testing. The Multi-Tone Distortion Task (MTD) is an add-on for our QC software framework that can be inserted as a test step (task) in any existing QC test. It ensures overall consistency of production electrically and acoustically.

The MTD task covers the following features and benefits:

• Multi-tone stimulus
• „Fingerprint“ testing of speakers and audio systems
• Stimulating harmonics and intermodulation distortion
