Audio Example 1 (Default Audio Configuration)
Always passback the audio EDID from the AVR on Output 1 to the HDMI sources.
Output 1 drives a receiver that has audio capability. Output 2 drives a display that you don’t use for audio.
This is the default case, and can be set as shown:
Always
Condition uses Audio EDID Audio Outputs

On Off On

Audio Example 2
A single line case with “User EDID” is shown below.
Because an HDMI device should not output audio to a
particular output if it is beyond the capability of the device attached to that output, each line has a user
selectable field to independently enable each audio output. These fields cover HDMI output 1, HDMI output
2 and the digital COAX audio outputs. So the default case has HDMI output 1and COAX audio turned on.
You should change the settings of the User EDID to match your system.
When you set the audio EDID to “User EDID,” a “User EDID settings” menu is shown (this is the “PCM 2 Ch
48KHz Y” entry below). You can use the “User EDID settings” menu to select which audio modes will be
advertised by the audio EDID. By default 2-channel PCM and DD 5.1 modes are enabled. Other modes must
be enabled using the menu commands.

Audio Example 3
Output 1 drives a projector, which doesn’t have audio capability (or it’s not used) and instead the COAX
audio output is used. Output 2 drives a second display, which has audio capability and uses HDMI audio.
When the second output is used, the video configuration is set to enable output2, and disable output 1. This
type of setup might have the two displays in different rooms with different equipment. This can be set as:

Audio Example 4
Output 1 drives a 1080p60 HDMI projector without audio capability, and output 2 drives an HDMI amp. In
addition, the amp’s HDMI output drives a 720p (max) LCD TV. When watching the projector (1080p60),
Output 2 should have audio only since the TV cannot accept 1080p60. When you watch TV you would select
720p video output, and turn on the video output on HDMI Output 2. One option is to set MEMA to output
1080p (and disable output 2 video), and MEMB to output 720p on both outputs. Audio can be set as:
If Out1
video on
Else if Out2
