6.5.1 Reference Input Sensitivity Adjustment Function
The Reference Input Sensitivity allows the measurement options for the SmartSMS unit to be
adjusted. This procedure must be done with new SmartSMS units if you want to use the Automatic
Equalization process, or the spectrum analyzer functions. The section below offers a detailed
description of this procedure.
There are two options for the reference input:
1) Soft dB microphone with IMIC USB device input
2) Sound Level Meter connected with the SMS
The Reference Input Sensitivity function allows the measurement option to be selected and the
measurement parameters to be set.
6.5.1.1
Precision microphone provided by Soft dB (with IMIC USB device)
If you use the Soft dB Precision Microphone & the IMIC device as the input, the software can
retrieve the microphone sensitivity by entering the serial number of your microphone.
Procedure:
Ø
Connect the IMIC device to a USB port on your computer.
Ø
Use the Measurement Option field to select the IMIC input.
Ø
Enter the microphone serial number; use the Change Mic. SN function.
To update the MicBank list, click on the "Update Micro Bank file" button in the additional functions
tab. This will download the latest micbank.inf file. Replace the old file located in the specified folder
by the new file. This will provide you with the latest micbank file available.
However, the sensitivity can be adjusted again and validated by using an acoustical calibrator. The
same procedure can be used as that described for the sound level meter (see below).
