of the pair which prohibition is accomplished by not activating the connect button 99 disconnection of inputs outputs from their ports essentially works in reverse and with the assistance of the disconnect button 100 for disconnecting a highlighted input or output from the map or the disconnect all button 101 for disconnecting all input and outputs from the map after automatic or manual mapping the administrator proceeds to the next fifth and final screen in the wizard by pressing next button 98 this fifth wizard screen in shown in fig9 and shows a design summary window 104 which provides another simplified representation of the input output map for the device this summary can be saved on the computer 28 as a text file by pressing the export summary button 106 where it can thereafter be printed and used by the administrator as an easy reference for physically connecting the inputs and outputs to the correct ports on the audio conferencing device as the final step in the wizard the administrator presses finish button 108 at this point the mapping and optimization parameters e g gain values are calculated by the wizard for example the wizard having knowledge of the acoustic properties of the inputs and outputs that left and right output channels need a 3 db attenuation that telephone inputs may require special filtering that certain selected output speakers may need a low frequency boost etc calculates optimization parameters accordingly in other optimization or mapping examples appropriate input and output gains can be set wireless microphones can be automatically mapped to sound reinforcement outputs stereo audio is only mapped to stereo amplifiers if both stereo and mono amplifiers are present mono audio is only mapped to mono amplifiers if both stereo and mono amplifiers are present inter.
