Selecting Audio Input Type and Routing to Mixer Input Channels
Use the In 1:4, In 5:8, In 9:12, and In 13:16 menus to select the type of audio input (SDI, AES, Analog,
or Decode) for each pair of input channels, and to direct them to a specific pair if mixer inputs. The
menus In 1:4, In 5:8, In 9:12 and In 13:16 correspond to mixer input channels 1 through 4, 5 through
8, 9 through 12 and 13 through 16, respectively. These four menus work in the same manner.
Using the In 1:4 menu as an example, when SDI is selected from the 1/2 Input drop-down control,
the following eight pairs of SDI channel selections are available in the control to its right: 1/2, 3/4, 5/6,
7/8, 9/10, 11/12, 13/14, 15/16. This reflects the 16 channels of audio that an SDI signal is capable of
carrying.
When AES is selected from the 1/2 input drop-down control, the following four pairs of AES channel
selections are available in the control to its right: 1/2, 3/4, 5/6, 7/8. This reflects the four AES connectors
available. Each AES connector can carry one pair of channels. (The 9550-XA has two additional AES
connectors, providing a total of six pairs of AES channels: 1/2, 3/4, 5/6, 7/8, 9/10, 11/12.)
When Analog is chosen, two pairs of channel choices are available: 1/2 and 3/4. This reflects the
capacity of the module to carry up to four channels of analog audio through the 15-pin D connector.
When Decode is selected, the following four choices are available: 1/2, 3/4, 5/6 and 7/8. When
decoding a Dolby D/AC-3 stream, a maximum of six channels are decoded. When decoding a Dolby E
stream, a maximum of eight channels are decoded.
Digital audio enters the module through either the SDI In connector or through the four AES inputs
(six AES inputs for the 9550-XA). Up to two pairs or four channels of analog audio enter the module
through the 15-pin D connector. A pair of wires carries one analog audio channel.
