Audio Input
With control panel shortcuts, you can select an input (or multiple
inputs) and immediately send it to all audio outputs. Directly press the
Audio In button (see Figure 2-6 on page 20 ) to select any one set of
audio inputs to be sent out to all audio multiple output sets. The LEDs
to the top, right side of this button indicate which input is currently
selected. When the selected input signal is absent, the LED flashes.
Available audio input groups include the following:
•
User
• Analog—4 mono channels of analog audio input
• AES—2, 5, or 8 stereo pairs
• SD—16 mono channels from the SD-SDI de-embedder
• HD—16 mono channels from the HD-SDI de-embedder
• Dolby Dec—10 channels from the internal Dolby decoder
Depending upon which input you have selected, the X75 unit
automatically and logically maps all output channels.
NOTE
The optional X75OPT-AS-8/16/32 module is required for
synchronizing, delaying and processing mono audio for SD-SDI
and HD-SDI inputs.
When you select two or more audio input groups, the Audio In Src
Select parameter is automatically set to the User setting, and this
control is available from the Audio Setup > Routing submenu.
To switch between mono and stereo audio processing control, press the
Ctrl and Mo/St buttons simultaneously. When mono control is active,
each button controls an individual gain. When stereo control is active,
the top and bottom front panel buttons work together (are “married”) so
that either button will adjust the gain in stereo pairs.
