- 2 microphone inputs (100 dB SNR)
- Preamplifiers for XLR and Microphone input controlled in 1dB steps to ensure maximal SNR
- ICP power for microphone, accelerometers and others
- 2 speaker terminals to measure tweeter and woofer simultaneously
- Galvanically decoupled current sensor up to 60 Amps
- Voltage sensor up to 300 V (4 wire Kelvin configuration)
- Interface for temperature and humidity sensor for climate monitoring
- General purpose digital input and output pins (GPIO)
The Production Analyzer is the sensor and data acquisition basis for the KLIPPEL QC software. It comprises a dedicated sensor front-end for speaker measurements as well as for professional AD/DA converter. The PA is equipped with built-in current and voltage sensors, provides a microphone power supply, symmetrical in- and outputs and digital I/O. It allows performing highly flexible tests on electro-acoustical transducers. It is a two-channel system which allows to measure two speakers under test in parallel or one driver while mounting the second driver in time critical applications, such as end-of-line testing.

- Channels can be extended by using multiplexers for XLR input and output, microphone and speaker channels. This is an example for 5.1 system testing using speaker and microphone multiplexers.
