•Two-channel Digital Mode: In this mode, you can select a channel group, then one pair of AES channels from that group to embed, using either the SDI Audio Decode option of the Audio menu or SIS commands (see the Audio Input Format commands on page 57. To select a channel pair:

1.Press the and buttons to select the group number (1 through 4).

2. Press the and buttons to select the channel pair number (1 or 2).

•Eight-channel Digital (Full Digital) Mode: In this mode, the first four pairs (eight channels, groups 1 and 2) are embedded (see the table below). You are not able to select a channel pair.

DSC HD-3G A: Audio Embedding

In PCM multi-channel mode, the DSC HD-3G A embeds up to eight channels of PCM HDMI audio onto the first four pairs of AES channels on the SDI output, in sequential order. In LPCM two-channel mode, the first pair of SDI audio channels is used (you cannot select a channel pair on the DSC HD-3G A).

All audio inputs on the DSC HD-3G A are automatically delayed to compensate for internal video processing.

The table below shows the channel pair mapping for the DSC HD-3G A.
