HDMI Audio Extractor w/ EDID Mgmt

1.0 Introduction

Thank you for purchasing the Hall Research EMX-HD-AUD. This versatile device can be used to extract the audio from HDMI, extend HDMI cable length, manage EDID (pass-thru or emulate), and re-clock both TMDS video and DDC data. The use of EMX-HD-AUD can often resolve system level HDMI signal-chain issues by acting as an intelligent intermediary.

The EMX-HD-AUD is powered from the HDMI source input and no additional power supply connection is needed for most applications. A USB power supply is included and may be used in case the HDMI source has limited power.

Use the EMX-HD-AUD wherever you want to diagnose or resolve HDMI issues. It can fix problems caused by incompatibility of components in the video signal chain, signal degradation due to long cables, or issues related to EDID.

Multi-color LED’s on the unit indicate the mode of operation with regards to EDID routing, and also provide real-time status on the HDMI signal’s video and audio. The audio outputs include stereo analog on a 3.5mm jack, Digital audio (2 or multichannel SPDIF) on optical TOSLINK connector, and of course the audio that is embedded in the HDMI output stream. Each of the audio outputs can be independently muted. For example, you can remove the audio from the HDMI output. This would be desirable in many applications if the connected TV’s audio were causing annoying echo due to processing delay.

The EMX-HD-AUD constructs an EDID table (capabilities list) for the connected source. This table either is copied verbatim from the connected display (sink) when in pass-thru mode, or substitutes an internal EDID data from on board memory. The internal EDID data can be learned from any connected display by using the buttons on the box, or uploaded to it from a PC via the USB port. Most importantly, the device maintains HDCP compliance regardless of the EDID routing mode, so HDCP protected content passes through the system with protection intact even when the EDID is emulated from internal memory.

The EMX-HD-AUD is HDMI 1.3 and 1.4 (deep-color and 3D) compatible, and automatically compensates for the signal degradation caused by long video cable runs of up to 50 ft (15 m) on its input and can drive HDMI cables on its output to 30 ft (10 m).

The package includes a universal power supply and a USB cable for connection to a PC. Free Windows™ PC software is available on the product’s website that allows reading, saving, manipulating, and writing EDID tables to and from the unit. The software can also be used to control the operational modes and provides diagnostic tools such as indication of the HDMI input signal’s video and audio characteristics.

3.0 Installation

The EMX-HD-AUD connects between the video source and an optional display device.

Connect the included power supply to the mini-USB connector on the video output end of the unit if needed.

Connect the HDMI or DVI video source to the EMX-HD-AUD video input. Connect the EMX-HD-AUD video output to the display device (not required for

operation). Connect the EMX-HD-AUD 3.5mm audio output and/or TOSLINK optical output to the

external sound system.

Though capable of driving long cables on its output, when used as an extender, it is best to place the EMX-HD-AUD at the far end of the long HDMI cable. In that way its automatic equalizer can clean the signal and open the TMDS “eye”

TMDS Signal at end of long Cable TMDS Signal after Equalization

The EMX-HD-AUD LEDs show the current device settings. Refer to the operations section for more information.

5.0 Power Requirements

This device requires 5 Volts DC which can come from the included power supply with a miniUSB connector or from Pin 18 (+5 V) of the HDMI connector.

To power the EMX-HD-AUD from the HDMI or DVI input power, the source must be able to supply a minimum of 100 mA (@ 5 vDC). Using a video source with insufficient power capabilities will result in erratic operation and loss of video.

6.0 Operation

o The EMX-HD-AUD buttons are recessed in the device to help prevent accidental

changes to the device settings and may require the use of a pointed device to press the buttons!

VIDEO LEDS

• EMULATE

o All portions of the EDID pertaining to video are from internally stored memory.

• PASS-THRU

o All portions of the EDID pertaining to video are from the attached SINK.

• Video input Status Indication

o A slow blink (~1/sec) indicates NON-HDCP content; a fast blink (~2/sec) indicates

HDCP content, no blinking indicates no video detected.

EMX-HD-AUD

AUDIO LEDS

• MULTI

o Audio EDID includes 2-channel LPCM, as well as multi-channel DTS and DOLBY.

• 2 CH

o Audio EDID includes 2-channel LPCM.

• PASS-THRU

o Audio EDID reported to the source is directly derived from the audio capabilities of

attached SINK.

• Video input Status Indication

o If Audio is embedded on the input HDMI signal, either the MULTI or the 2CH LED

positions will be blinking to indicate the type of Audio that is being received. Note that the Analog output is muted if the received HDMI audio is multi-channel.

LEARNING an EDID

o Press and hold the VIDEO button for approximately 3~5 seconds until the

EMULATE LED starts blinking

o Release the button, the EMULATE LED will continue blinking while the unit reads

the EDID from the connected output.

o If the EDID reads successfully, ALL LED’s will illuminate one at a time in a

sequential pattern 5 times.

o If the EDID was NOT successfully read, the PASS-THRU and EMULATE VIDEO

LEDs will alternately flash 5 times to indicate the error. This usually indicates either a cable issue or the connected OUTPUT device has an invalid EDID.

SET FACTORY DEFAULTS

o Press and hold BOTH the AUDIO and VIDEO buttons for approximately 3~5

seconds until BOTH the VIDEO EMULATE and AUDIO MULTI LED’s start blinking together.

o Release both buttons. o If the factory defaults were successfully restored, ALL LED’s will illuminate one at a

time in a circular pattern 5 times.

7.0 Free Windows Software GUI

The EMX-HD-AUD is controllable via a free Windows™ based GUI available on the Hall Research website http://www.hallresearch.com.

All of the device features, and more, are accessible from the GUI. EDID files can be exported and modified

party software and imported

using 3 back into the EMX-HD-AUD. The device is also capable of writing custom EDID data back to compatible display devices.

The user guide for the Software GUI is only available on the website.

8.0 Troubleshooting

No LEDs illuminate............................................................... Check power supply

Device will not remember settings or will not LEARN and EDID or the LEDs only momentarily FLASH when buttons are pushed

No Video ................................................Verify cabling and check power supply.

.............................................. Verify HDCP compliant display for HDCP content.

.........................................................................Verify GUI DDCcontrol is enabled.

No Audio..................................................Verify source audio and video formats

If neither MULTI nor 2CH LED’s are blinking, input may be DVI rather than HDMI video. Ensure GUI ‘MUTE’ controls are set correctly and not MUTED. The 3.5mm stereo audio is only active when the HDMI audio format is 2-channel LPCM.

EDID Not Learned Correctly ...... Ensure VIDEO & AUDIO modes not changed

When an EDID is learned, the EMX-HD-AUD is placed in Pass-Thru modes for both Video and Audio. In these modes, the EDID will remain un-touched and can be exported, if desired.

If either VIDEO or AUDIO modes are changed; the EDID will be mixed to have audio capabilities. The previous ‘un-touched’ EDID will no longer be available unless previously saved.
