Section 6 – Audio Configuration
The RadianceXE supports the HDMI 1.4 audio formats. This means that Dolby Digital TrueHD™ and DTS
Master-Audio™ are available in the RadianceXE.
By default the audio EDID from the device connected to HDMI Output 1 is passed back to all 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 settings).
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 outputs 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 1
•
HDMI receiver connected to HDMI Out 1 and (non-audio) display connected to HDMI Out 2
•
HDMI receiver connected to HDMI Out 1 with a display connected to the receiver’s HDMI output
•
SPDIF receiver connected to COAX Audio Out and (non-audio) display connected to HDMI Out 2.
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.
NOTE:
When using the COAX SPDIF audio output, the audio EDID should
be set to “Always USER1 EDID” in the main audio menu.
Some important concepts for selecting the audio configuration are:
• Audio from any audio input (HDMI, SPDIF, analog) can be routed to one or both of the HDMI
outputs, and/or the two COAX outputs, with the appropriate limits on the output format. For
example, the digital COAX audio output can only carry 2-channel PCM, Dolby Digital, and DTS.
•
HDMI audio EDID reported back to the HDMI sources can be passed-back from either of the two
HDMI outputs, passed back from the common elements of the two outputs (i.e. only features
supported by both outputs are enabled), or specified by the user (User EDID).
•
The audio EDID reported back to sources can change dynamically, as configured by the user,
based on which HDMI output has active video. NOTE: 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 audio output enables, are global parameters. That is, they change (only) when
the active output changes. NOTE: The Audio EDID mode is independent of the Video EDID mode.
