Receive EQ (Caller Dynamic Digital EQ – DDEQ)
Telephone audio frequency response varies widely since many factors can affect it (we’ve measured the response on a number of calls and the results were revealing). Consequently, some form of receive equalization is desirable. There are three choices for the type of equalization applied to the received telephone audio:
♦♦ Off – The caller audio is passed through without modification. The Rcv EQ values are ignored in this mode.
♦♦ Fixed – This is a simple manual equalizer mode where a fixed EQ is applied.
♦♦ Adaptive – This is a three band dynamic equalizer. The high and low frequency boost or cut is automatically determined and set. The Dynamic EQ uses the values set below as ‘target levels’.
