K & K International is specialized in test and measuring systems used for production testing, development of products as loudspeakers units, loudspeaker systems, headphones, telephone handset and microphones.
The product
program covers from high performance and high-speed test systems to
small low price test systems.
A wide range of parameters can be measured at same time in parallel
enabled by multi core processors.
Benefits as System Multiplexing enable to work on 2 different test systems at same time and with a multi chain function a unlimited test sequence is possible.
The software is split in an unskilled operator mode, an engineer
setup mode and an R&D engineer mode. As a return of a test in
operator mode an approved / reject or as a full graph will be
displayed. At same time measured data for further statistical
analyze can be stored.
Tools to find the golden unit from stored
data.
The systems make use of a unique password control and a unique recovery manager.
List of common test parameters:
| Frequency response | Average of Frequency | SPL |
| Sensitivity | Average of Sensitivity | Polarity |
| Phase | Rub & Buzz | THD |
| Impedance | Resonance | Qms |
| Qts | F (Fres./Q) | Re |
| Current Distortion | EBP | Voice Coil offset |
| T/S parameters | Ambient Noise Control | Cpk / Ppk |
