Section 6 – Audio Configuration
The Radiance supports the HDMI 1.4 audio formats. This means that Dolby Digital TrueHD™ and DTS
Master-Audio™ are available.
By default the audio EDID from the device connected to the HDMI Output is passed back to the source
devices. There are two methods that can be used to change this. Typically the audio menu (MENU →
Audio) is used to program the audio EDID mode. For most cases the audio menu is all that is needed to
setup the audio EDID. However, in some cases a specific input, or input memory, may need to use a
different audio EDID. In this case the audio EDID for each input memory can be changed (MENU → Audio
→ Audio EDID).
Introduction to the Audio Menu
The Audio menu configures the audio EDID reported back to HDMI sources and is independent of the
Video EDID mode. In addition it selectively enables audio output based on the specified conditions. Many
common system configurations can use the default Audio mode settings. Some examples of these are:
•
HDMI television (with audio) connected to HDMI Out
•
HDMI receiver connected to HDMI Out with a display connected to the receiver’s HDMI output
NOTE:
Associating an audio input with a video input is done using the Input menu
MENU → Input → Audio Setup → Source → (audio source) → OK.
NOTE:
For best switching, and power-on, times manually select the output resolution and select
“USER1 EDID” for the audio mode. For example, for a 1080p60 display pressing MENU 0 2 7 OK
selects 1080p60 and eliminates the need for the Radiance to read the display video EDID.
Selecting “Always”, and “USER1 EDID” in the Audio menu eliminates the need for the Radiance
to read the audio EDID information from the AVR/TV. See the Output Configuration Commands
section, and Audio section, for more information. Remember to save any changes.
Some important concepts for selecting the audio configuration are:
•
Audio from the active HDMI Input can be routed to the HDMI output.
• HDMI audio EDID reported back to the HDMI sources can be passed-back from the HDMI output,
or specified by the user (User EDID).
•
Some sources update their EDID information only when they are powered on, or do not properly
reread EDID when the HDMI Hotplug signal is toggled. If you have a source that reads EDID only
at power-on, or does not respond properly to Hotplug, a single EDID mode should be enabled (e.g.
select “always report user EDID” as described below).
•
Selecting “User1 EDID” is the recommended practice. This allows the Radiance to report the EDID
back to the HDMI sources even when the display or receiver is turned off. This can also
significantly shorten the system boot time. However, in this case, care must be taken to select only
audio modes that the audio processor supports.
•
Default “User EDID” mode is 2-channel PCM and Dolby-Digital 5.1 only. The user can change the
“User EDID” to include any audio modes supported by the Radiance and the audio processor.
• Audio EDID, and the audio output enable, are global parameters. The Audio EDID mode is
independent of the Video EDID mode.
•
You can over-ride the global Audio EDID for a particular HDMI input by selecting MENU → Input
→
Audio Setup → Audio EDID → Custom → Ok. Set the audio modes to “Y” (yes) that you
want to report back the source for that input.
• Audio is muted when changes are detected on the input. Some audio receivers need to be muted
longer to avoid unintended noise. MENU → Input → Audio Setup → Mute Control → Long →
Ok
