The Speaker Test Software “RT-Speaker” provides in combination with the FX100 Audio Analyzer a comprehensive solution with a unique and reliable defects analysis. The objective Rub & Buzz analysis correlates 100% to the subjective perception of the human ear. The typical cycle time for a complete speaker test is less than two seconds.

Introduction
Main Menu
The Speaker Test Software main menu provides quick access to all key functions – test setup, measurement tools, results, and reporting – in one clear overview.
PureSound Rub & Buzz Measurement
PureSound™ detects the slightest Rub&Buzz defects of speakers or transducers, such as air-leaks, uncentered coils, rubbing voice coils, loose particles and touching wires. The fastest and most reliable test results are guaranteed, even with high factory environmental noise. The typical test time is lower than one second, depending on the speaker type, frequency range and resolution. Make your business more successful by improving your product quality control and saving costs with PureSound™ Rub&Buzz testing.
Calibration and Recording of Reference Data
The main menu guides the production administrator through the basic system configuration on to the test parameter settings, which are contained in a single “Project“ folder. After an automated calibration sequence a representative set of one or more “Golden Samples” can be recorded.
The unique tolerance management derives its tolerance criteria automatically and supports up to five different quality clusters, which may be user-defined in any language, such as “Excellent”, “OK”, “Acceptable”, “Class 3” and “Reject”. The manufacturer may then, for example, charge a premium for “Excellent” products or match similar speaker pairs for stereo applications.
Speaker Production Testing
A simple PASSED/FAILED readout or a detailed view of all measured speaker parameters is provided to the operator. System integration into existing high volume production lines and the connection to host controllers is very simple. The patented measurement algorithms have been optimized for factory noise immunity.
Measurements can be started by an external button or automatically as the speaker is connected. The built-in FX100 digital IO interface can be used for automated operation, such as
Communicating with a PLC
Test result indication through a stack-light
Triggering a measurement with a footswitch
External pre- or post-test actions independent of test result
Automated splitting of PASSED/FAILED samples
Individual bin splitting of different FAILED samples
RT-Speaker Editions
The RT-Speaker PC software is available in three fully compatible editions.
Basic Edition
For companies that want to replace their subjective ”Golden Ear” test with a cost-effective, objective test system that creates consistent results. This edition contains the Rub&Buzz test that uses NTi Audio’s PureSound™ technology.
Standard Edition
Designed for companies who test smaller quantities of loudspeakers, such as R&D, sample QC testing or PA rental companies. While the Standard Edition still offers the complete set of measurement functions, the test system can only be operated in manual mode.
Premiere Edition
Contains the full RT-Speaker functionality and is therefore the optimal solution for testing mass production of loudspeakers. Besides the complete set of measurement functions, the Premiere Edition offers numerous helpful features for system integration such as digital IO, TCP/IP interfaces and barcode scanners. Various user access rights, a comprehensive statistic tool as well as the ability to classify results complete the list of features.
FX-Control
All three editions also enable the PureSound Rub&Buzz defect detection in the FX-Control software.
Upgrades
Upgrade and evaluation licenses are available for all three editions.
As a research laboratory invested in supporting communities through real time noise monitoring, I am very happy to exclusively use NTi instruments. Not only are the robust, easy to use, and provide high quality data, the customer service is outstanding and their team will work with you to find the most cost effective and appropriate solutions needed for problems ranging from easy to difficult.

I’ve been using the XL2 for over 15 years for short-term and long-term measurements in all kinds of indoor and outdoor environments all across the country. The meter gets me what I want, when I need it. It’s not only the best value for acoustical measurements, it’s the best tool period. I bet my company and reputation on XL2 results and it has not let me down. You would be crazy not to consider adding NTi instruments to your toolkit.

We at Constructure GmbH use two XL3 sound level meters for noise monitoring during demolition work. We are very satisfied with these highly user-friendly instruments, the online monitoring in the MeasurEye Cloud, the good advice and qualified support. Factory calibrations at NTi Audio are also handled very smoothly and without complications.
