Section 6 – Audio Configuration

The Radiance 2022/2042 supports the HDMI 1.4 audio formats. This means that Dolby Digital TrueHD™ and

DTS Master-Audio™ “bitstream” formats are available.

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 w ith a video input is done using the Input menu

MENU → Input → Audio Setup → Source → (audio source) → OK.

NOTE: The Audio EDID mode is independent of the Video EDID mode.

NOTE:

For best sw itching, and pow er-on, times manually you can 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 “Alw ays”, 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 “Alw ays USER1 EDID” in the main audio menu.

Some important concepts for selecting the audio configuration are:

Audio can be routed to one or both of the HDMI outputs, and/or the COAX output 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, and/or audio EDID selected in the input memory.

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

used (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. 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.
