SAP/DVS audio on channel 7 will made a dual mono pair and loudness controlled.
• SAP/DVS is typically not present for all programs. In order to maintain audio on the SAP
channel a loudness controlled downmix of Program 1 (Or simply the stereo audio of
Program 1) can be used to automatically replace SAP when there is no SAP source. The
assures that programs, promos, commercials and any content that does not have SAP
audio will have the main program (Program 1) audio on the SAP channel instead of
silence.

When using a 5.1 Instance (AMX5.1) two downmixes can be created. One uses the DRC
Program 2 output and one uses the DRC Local output. In some applications a downmix is
embedded in the SDI output for use downstream. For example, an SD output can be down-
converted from the HD video, and the stereo downmix can be used for this.
