After reprogramming 2.2 MINI firmware make sure that you reprogram Microphone Calibration File!

Microphone Calibration File

Each Tact-2.2 MINI system is supplied with a factory calibrated measurement microphone. The microphone calibration file is saved on the Tact-2.2 MINI distribution CD. When you get your microphone calibration file, (Example: "Mic004256.mic"), on the distribution CD or via e-mail, it is recommended that you copy that file into the "...\Tact-2.2 MINI\Mic" directory for future reference. You can copy the file manually or you can use the Microphone option in the File menu.



After clicking on the Microphone option ,find the mic file (CD or other media), select it and click on the Open button. This will automatically copy the mic file into the "...\Tact-2.2 MINI\Mic" directory. Note that the Microphone option has no other function than to place the mic file into the proper directory.

To install the microphone calibration file into Tact-2.2 MINI internal memory, click on the Save Mic Calibration option in the File menu. This will open the Microphone Calibration window.



Click on the Open button and find the microphone calibration file on Tact-2.2 MINI distribution CD (or other media). Select the microphone calibration file and click on the Open button. The selected file name will appear in the Mic file name field. Click on the Save button to send and save the mic calibration data to Tact-2.2 MINI internal memory.

After the installation process is completed and after 2.2 MINI is restarted (place 2.2 MINI into STANDBY mode and then turn it ON), the microphone installation information will appear on Tact-2.2 MINI, front panel accessible, MSR menu option.

In order to complete the mic calibration file installation, the Tact-2.2 MINI has to be connected to a PC and the RS232 communication has to be functioning properly.

2.2 MINI will use microphone calibration file only if MIC CAL option in MSR menu is set to ON.
