Introduction
OVERVIEW
The Hall Technologies HD-AUD-IO is an all-in-one HDMI audio manager capable of
extracting audio from (de-embedding) and inserting audio into (embedding) an
HDMI video signal. The product also provides EDID management features.
The product provides one HDMI input with a corresponding HDMI output. The HDMI
input audio signal simultaneously extracts to both 2-channel L/R analog and
Digital SPDIF (TOSLINK).
The product provides two audio inputs (analog and digital). Users can select
which audio to embed in the HDMI output. It can be the same as the original
HDMI audio (pass-thru), SPDIF digital, or 3.5mm L/R analog.
Advanced EDID management allows users to control the video portion as well as
the audio part of the EDID. The EDID presented to the video source connected
to the HDMI input can pass from the downstream device or emulate an EDID from
internal memory. The device can also “Learn” the EDID connected to its HDMI
output.
The product has a video bandwidth of 18 Gbps and supports resolutions up to 4K
@ 60 Hz 4:4:4 with HDR. It supports HDCP 2.2 as well as HDCP 1.4 if needed.
The device has the ability to generate and output a blank HDMI signal with
audio embedded even if there is no HDMI input; often referred to as “HDMI
Audio Bridging”. This is a convenient means to distribute audio only signals
over an HDMI network.
The HD-AUD-IO has a configurable digital input terminal that can mute the
audio and/or video.

Setup
Installation
-
Optionally, connect an HDMI source to the HDMI IN connector. Note that a source is NOT required to embed audio onto the HDMI output.
- If there is no HDMI source signal, the HDMI Output will be a 640×480 (480P) black screen.

-
Optionally, connect the SPDIF OUT audio output to a compatible audio device.
Optionally, connect the L/R OUT analog audio output to a compatible device (e.g., headphones, assistive listening devices). -
Optionally, connect the audio to embed to the SPDIF IN and/or L/R IN connector(s).
-
Optionally, Connect the TX, RX and GND contacts on the Control terminal strip to a compatible controller (e.g., PC or RS-232 controller).
-
Optionally, Connect the DI contact on the Control terminal strip to a compatible normally open dry contact. This can be configured to mute the audio and/or video. Factory default is to mute the audio output. (Closed = MUTE)
-
Optionally, use the included rack mount brackets and hardware. The brackets are configurable for different mounting orientations.
-
Connect the included power supply to the 5V DC connector.

Windows Graphical User Interface
The HD-AUD-IO is controllable via free Windows® based software available from the Hall Technologies website at: http://halltechav.com/product/HD-AUD-IO Software Installation Prerequisites
- A PC with Windows XP® OS or later
- USB port
- Microsoft® .NET Framework 2.0 or later (most recent OS including Windows 8 and later include this software and no action is required). If the .NET Framework 2.0 or later is not installed on your PC, the Microsoft™ website has free downloads available.
Software Installation
If an earlier version of this particular software was previously installed,
UNINSTALL the program first from either the Add/Remove Programs section of the
control panel or by running the previous installation’s SETUP.EXE and
selecting “remove application”.
- Install the software by executing the SETUP.EXE program from the installation source directory
- Accept the default settings, but if you want to specify a particular installation directory other than the default, you may do so.
- Once the HD-AUD-IO software installation has completed, either click the desktop icon or navigate the Start Menu to Start -> Programs -> Hall Research -> HD-AUD-IO
General
In most installations the use of the software GUI is not required as most
functions can be performed using the front panel buttons on the product.
You can use the software to export EDID files from the device.
It is possible to connect more than one HD-AUD-IO to the PC (using several USB
ports of the PC). The same software GUI detects all connected devices and
allows control from the same application.
USB Device Detection
The HD-AUD-IO software uses standard Windows® drivers, which automatically
configure the USB port after connection and do not require the installation of
any special USB drivers.
The first time you connect the HD-AUD-IO to the PC, you may experience a short delay and a windows notification pop-up message may display.
- The software GUI scans the HD-AUD-IO settings continuously in real-time, all changes to the system are reflected in the software GUI.
- If no HD-AUD-IO device is attached to the system, the on-screen fields are disabled (grayed out).
- The new device detection and driver auto installation typically only occurs once. Thereafter, devices that are reconnected detect with no delay or message.
Only one instance of the software GUI can run at a time.
Executing the application more than once will result in a warning message.
Tool Bar Menu
EXIT
Exits the application
TOOLS
Factory Defaults
Restore the device to factory default settings. The user must confirm the
action.
Export EDID
Save the currently selected EDID as a 256-byte binary file.
Firmware Update
Allows users to field upgrade the device application firmware. Application
firmware that does not support this function will disable this option.
ABOUT
Displays screen with software versions, website link, legal disclaimer and
copyright information.
Status Bar
The bottom bar of the screen shows the current USB status as follows:
“Scanning for Hardware…”
The GUI software is looking for HD-AUD-IO devices.
The screen controls are disabled until a HD-AUD-IO device attaches.
“Connected – XX”
Where XX is the number of HD-AUD-IO devices connected to the PC.
Controls
Embed Source
This button selects which audio source to embed; either 3.5mm L/R IN, SPDIF IN
or HDMI IN.
Audio EDID
This button selects how the EDID is altered; either L/R (2 Channel), Multi
(Multi Channel) or Pass-Thru from the HDMI output.
Video EDID Emulate/Pass-Thru
Pressing this button quickly selects whether the EDID given to the source is
from a previously stored EDID or from the HDMI OUT display.
Digital Input
This area controls and shows the desired mute setting which occurs when the DI
(digital input) terminal connects to ground.
The indicator will be ‘RED’ when the DI is un-grounded and ‘GREEN’ when the DI
input connects to ground.
The factory default setting is to mute only the HDMI audio output. Click the
desired setting to change the factory default.
| Setting | Functionality |
|---|---|
| OFF | No Audio or Video muting |
| AV Out | Both HDMI Audio and Video are muted. (Extracted HDMI Input audio is |
not affected)
Video Out| Only HDMI Video is muted
Audio Out| Only HDMI Audio is muted L/R and SPDIF audio modes, the extracted
audio also mutes
Both Ext| Both L/R Out and SPDIF Out are muted HDMI Output audio is not
affected
Ext L/R| Only L/R Out is muted HDMI Output audio is not affected
Ext SPDIF| Only SPDIF Out is muted HDMI Output audio is not affected
Audio Muting
This area controls and shows the current system muting state. This setting can
be different from the setting above for when the Digital Input.
For example,
With ‘Audio Muting’ set for ‘AV Out’ (both Audio and Video muted) and the
‘Digital Input’ setting is set for ‘Audio Out’.
When the Digital Input terminal connects to ground, the Audio and Video muting
state shown in the ‘Audio Muting’ area will change from ‘AV OUT’ to ‘AUDIO
OUT’
Troubleshooting
If you are experiencing problems getting the system to work properly, please use the following troubleshooting suggestions.
- Ensure that all connections to the device are solid. Loose connections are the number one cause of issues.
- Try resetting the system by unplugging BOTH the power supply and HDMI IN connectors, waiting 5 seconds and plugging them back in.
- The front panel LEDs cycle several times at power up; after ~15 seconds, audio and video should be passing through the device.
- Try restoring factory defaults using the front panel VIDEO EDID button (hold for 7 seconds) or via RS-232 command.
- Cycle the EDID mode with the front panel VIDEO EDID button.
- If you are having problems with ‘muting’ the AV output, ensure you have the correct mute settings.
- The muting of video is normally done with a ‘BLACK’ screen (AVMUTE). If you need to have “NO HDMI” output, you will need to use the TX MUTE setting (DIA7 or MUT7).
