HDMI 2.0 Audio Inserter & Extractor

1.0 Introduction

The Hall Research 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.

3.0 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 640x480 black screen.

• Optionally, connect an HDMI compatible sink to the HDMI OUT A sink is not required to extract the HDMI Input Audio.

• Optionally, connect the SPDIF OUT device.

• Optionally, connect the L/R OUT device (e.g., headphones, assistive listening devices).

• Optionally, connect the audio to embed to the SPDIF IN connector(s).

• Optionally, Connect the TX, RX and GND strip to a compatible controller (e.g., PC or RS-232 controller).

• Optionally, Connect the DI 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.

6.0 Windows Graphical User Interface

The HD-AUD-IO is controllable via free Windows® based software available from the Hall Research website at:

http://hallresearch.com/page/products/HD-AUD-IO

1.1. 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.

1.2. 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

1.3. 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.

Page 11

1.4. 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.

1.4.1. The software GUI scans the HD-AUD-IO

settings continuously in real-time, all changes to the system are reflected in the software GUI.

1.4.2. 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 messa

1.4.3. Only one instance of the software GUI can run at a

time. Executing the application more than once will result in a warning message.

1.5. Tool Bar Menu

HDMI 2.0 Audio Inserter & Extractor

1.5.1. EXIT

Exits the application

1.5.2. 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.

HD-AUD-IO

1.6. 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.

1.7. 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.

Press and hold the button for more than 3 seconds. After the LED blinks once, release the button to LEARN the EDID connected to the HDMI OUT connector. If there is an error learning the EDID, the VIDEO EDID LED will blink 10 times.

Press and hold the button for more than 7 seconds. After the LED blinks twice, release the button to factory default the device.

Page 13

1.8. 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 muting occurs AV Out Both HDMI Audio and VIDEO are muted Video Out Only HDMI Video is muted Audio Out Only HDMI Audio is muted Both Ext Both L/R Out and SPDIF Out are muted Ext L/R Only L/R Out is muted Ext SPDIF Only SPDIF Out is muted

1.9. 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 and the Digital Input setting is OFF. When the Digital Input terminal connects to ground, the Audio and Video muting turns off.

7.0 Troubleshooting

HDMI 2.0 Audio Inserter & Extractor

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.

o 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.
