4. This facility is for example useful to group the data into purely individual quality groups 75 Sub module 1 Optional groups replace the standad group settings With this facility up to ten different quality groups symmetric around the reference value can be defined The screen menu for this option is shown on the next page Any quality group of a higher number will have tolerances more remotely removed from the reference value than any lower group however include all data from the lower group s The input for each group is the tolerance in dB from the reference value Each group is thus symmetric around the reference value Each group with a higher number MUST have a tolerance value that is higher than any lower group Sub module 2 Optional groups replace the standad group settings With this facility up to five different quality groups can be defined Any quality group of a higher number will have tolerances more remotely removed from the reference value than any lower group however include all data from the lower group s The input for each group is the tolerance in dB and the tolerance in dB from the reference value Consequently each group does not need to be symmetric around the reference value Each group with a higher number MUST have a tolerance value that is higher than any lower group and a tolerance value that is lower than any lower group 76 1 Run Speaker Tests

11. Hardware Concept The system hardware consists of a standard industrial 19 Rack with standard sized modules which easily can be plugged in out This allows a very flexible serviceable and adaptable construction built not only for the present but also for the future as the customer very easily can construct or reconstruct the system to meet his actual demands The system hardware is prepared for up to six individual microphone input modules for all kind of purposes and or placement of test microphones The system embodies an input multiplexer This adds up to that it is the software not the hardware which connects the microphones to the personal computer ensuring a high flexibility By installing an optional internal microphone power supply module it is possible to mix all kinds of suitable microphones B amp K measuring microphone Phantom coupled Electr etc There are as standard two individual outputs which can be selected freely by the software Impedance measurements are performed using an internal series resistor which is sized by software The system input output is opto coupled and is used for external control and processing In the standard delivery a push button box is included which often is to prefer instead of the PC keyboard in a production environment The external control possibilities support start end of test and sending the results to an output device More uniquely the system also embodied a built in system
