PA Rental
The XL2 with Spectral Limits Option offers an efficient, low-cost solution for the quality control of speakers at PA Hire. Measurements can be compared against a reference curve with customized tolerance bands.
The pass/fail results are provided by the internal tri-color LED or an optional external Stack Light. Integration tools for automation and remote operation are provided.
- For quality control and service
- Test of returned speakers and microphones
- Passed/failed measurements
Overview
- Handheld and compact design
- Turnkey solution for passed/failed measurements in one unit
- Measurement starts by level trigger, external foot switch or instrument start button
- Improved efficiency with dedicated measurement profiles
- Automated documentation
Measurement Functions
FFT Analysis
Compares the high-resolution acoustic pattern of any device against a pre-defined reference sample with a pass/fail analysis in linear X-scaling.
1/12 Octave Analysis
Passed/Failed measurements with selectable 1/1, 1/3, 1/6 or 1/12 octave band resolution in logarithmic X-scaling.
Pass/Fail Measurements
The XL2 Analyzer captures the frequency spectrum of reference speakers/microphones and supports generation of tolerance bands based on the captured reference data. Measurements can either be displayed as absolute traces or shown relative to previously stored traces. Frequencies with failed results are individually visualized in every frequency band
Stack Light
Provides visual pass/fail indication.
Auto-start Function
Measurement starts by automatic level trigger, external foot switch or instrument start button.
Tolerance Management
Tolerance curves can either be imported from txt-files or directly derived from captured measurements. The XL2 calculates tolerance bands based on
- Single captured results
- txt-files manually generated on the PC
- Mean average of multiple captures
- Min/Max curves of multiple captures
Digital I/O Adapter PCB
For automated operation with external peripheral devices the XL2 Analyzer can be linked into a programmable logic controller. The Digital I/O Adapter is tailored for rail mounting in electric switch boxes.
