Input Peak Level

The measurement of the input levels to the IPAM based devices (Annuncicom, Instreamer and Exstreamer1000) is provided by the A/D Converter Quasi-Peak Detector Readout. In some application FW the value is provided as raw value while in other is displayed as dBs. THe following conversion can be applied. The value range is from 0..32767 (32767 for full scale), linear, referring to full scale (7FFFhex, 32767 is 0dBFS). 

0000        - 0% 
2000        - 25% (-12dBFS) 
4000        - 50% (-6dBFS) 
7FFF        - 100% (0dBFS)
