HDMI/DTP Embedded Audio Output
By default, the original embedded audio present on the selected HDMI or DTP input is
routed to the selected HDMI or DTP audio output. If an RGB input is selected there will be
no audio output. Optionally, program audio can be routed to the embedded output instead
(see
NOTE: If the sink device connected to the DHMI/DTP output is DVI, then the signal is
HDMI Audio Mute
The HDMI or DTP embedded audio output can be muted permanently by setting the
Mute HDMI Audio dip switch (see figure
Program Audio
The selected audio input is simultaneously switched to the program variable audio output,
fixed audio output, and the volume level of the amplifier (MA and SA only). The front panel
input LED selected for program audio output blinks.
Embedded Audio and Analog Audio
If the selected HDMI or DTP input has embedded audio, the switcher extracts the digital
audio and converts it to analog for program audio output, fixed audio out, and amplfiied
audio output (MA and SA only). If there is no embedded digital audio, the switcher selects
the current input analog audio (see figure 2,
NOTE: When the selected input has both embedded digital audio and analog audio
Program Audio Breakaway
Program audio breakaway allows routing of the audio signal from any input to the program
audio output independently from the input video signal. It is available by software control
only (see
analog audio input must selected, also by software control.
NOTE: Digital (embedded) audio cannot be broken away from the digital source.
Fixed Output and Variable Output
The balanced and unbalanced wiring of inputs and outputs result in different audio levels.
Refer to the following table for fixed output audio levels based on input and output wiring.

available, by default the switcher extracts the embedded digital audio for the audio
outputs. Using SIS commands, the default can be changed to select the analog
audio input instead. This is individually configured for each HDMI input .
Program audio breakaway
By default, the HDMI or DVI inputs cannot be broken away to or from, unless first
