Introduction

In the AVPro Edge AC-AVDM-V3, the multichannel bitstream of an HDMI signal is decoded, then combined to create a downmixed secondary output for distribution by 2-channel audio systems.
Commented [RK2]: Bypass refers to passthrough operation. May be better to state the multichannel bitstream is decoded and combined to create the downmix
Downmixing is necessary when a multichannel signal is required to be sent through as few as two speakers, with no subtraction of the original content. For example, eight discrete channels of audio information can be “collapsed” into two channels, creating a stereo signal for distribution. The original purpose of downmixing was to enable playback of multichannel movie sound over television speakers. Stereo downmixing for television is called Lo/Ro (Left only/Right only) and is often referred to as the ITU Downmix. The downmix is created by combining Left, Center, and Left surround information together from an original 5.1 multichannel signal. 3D immersive soundtracks are downmixed in a diﬀerent manner, however, no from the original multichannel mix is discarded. As most bass information is non-directional, a degree of LFE content is steered into the downmix, but not overly so that it would impact small speakers. Like the Left channels, the Right channels are also combined, enabling the downmix to maintain stereo compatibility.
Commented [RK3]: Remove mention of mono as we are not allowed to mix to mono from multichannel
The AC-AVDM-V3 supports decoding of Dolby® and DTS® formats, outputting single-ended analog stereo audio,
Commented [RK4]: Single-ended, stereo analog audio or 2-channel, single-ended analog audio
Commented [RK5]: ARC is an audio input. Audio can be input from the input HDMI bitsteam or ARC in from the designated HDMI output.
The diagram below illustrates how content may be viewed in a home theater with Dolby Atmos® and enjoyed in secondary zones by the AC-AVDM-V3 converting bitstream audio into 2 channels from the extracted analog ports.

Key Benefits

Downscaling & Dual Output: The AC-AVDM-V3 built-in scaler can input 4K signals including HDR, then downscale the output into 1080p, enabling retained use of legacy HDMI AVRs incapable of supporting higher bandwidth video while passing the full video signal to the display from the HDMI 2 output.
Audio Downmixing: The AC-AVDM-V3 is perfect for downmixing/extracting audio from formats such as LPCM 7.1CH, DTS®, DTS® ES, DTS:X®, AC3, Dolby Digital™, Dolby Digital Plus™, Dolby® TrueHD, and Dolby Atmos®.
EDID Management: Use the on-board 4K EDID or use EDID READ to copy a downstream EDID.
ARC Management: With ARC (Audio Return Channel) management, audio returning on the ARC Channel may be downmixed for use by a legacy AVR, a 2-channel system, or for distribution.
Detection Indicators: Front panel LEDs illuminate to indicate signal type.

Installation

Connecting the Devices

onnect the provided 5V/2A power supply to the DC/5V POWER port on the AC-AVDM-V3. All front panel LED indicators will flash once, indicating the AC-AVDM-V3 has powered on.
Power on the source device. Connect an HDMI cable to the HDMI INPUT port on the AC-AVDM-V3. The front panel SYSTEM STATUS IN LED will illuminate solid blue, indicating an active source is connected.
Connect the HDMI output device(s) to the HDMI OUTPUT port(s) with an HDMI cable.
Connect the distributed audio device(s) to the DOWNMIXED ANALOG or DIGITAL AUDIO OUTPUT ports using RCA, digital coaxial, or optical cables (depending on application).
Depending on the application, use the SETTINGS DIPSWITCHES on the rear panel or the AUDIO SOURCE SELECT button on the front panel to adjust downscaling, downmixing, and ARC options.

Dipswitch Settings

Each dipswitch located on the AC-AVDM-V3 front panel corresponds to one control setting.
Dipswitch UP position = OFF
Dipswitch DOWN position = ON

Audio Source Select Button Operation
The AUDIO SOURCE SELECT button, located on the front panel, controls the extracted audio modes as indicated by the solid blue adjacent LED:

Short (quick) Press:
LED is ON = Audio is extracted/decoded from the ARC (Audio Return Channel) HDMI OUT 2 port
LED is OFF = Audio is extracted from the input source device on the HDMI INPUT port (default mode)

Long (3 seconds) Press:
Press and hold for 3 seconds to toggle on Dolby® DRC (Dynamic Range Compression). The ARC LED will
blink once to indicate the DRC mode is enabled and remains in this mode after power cycling. To disable
DRC mode, press and hold the button for 3 seconds.

Front Panel Indicator Lights

Audio Detection
Each blue LED indicates the incoming audio signal type and format, based on the AUDIO SOURCE setting located on the front panel:

PCM: Indicates an active audio signal is being detected/decoded
DTS: Indicates DTS bitstream audio is being detected/decoded DOLBY: Indicates
Dolby bitstream audio is being detected/decoded

System Status
Each blue LED indicates the HDMI source device is connected and which port/s are active/connected:

IN: Indicates the source device is connected to the HDMI INPUT port
OUT 1: Indicates HDMI OUTPUT 1 is active/connected
OUT 2: Indicates HDMI OUTPUT 2 is active/connected

If the LEDs are ﬂashing or not illuminating, and there is no image on the display, verify the following:

Bypass the AC-AVDM-V3 and plug the source directly into the display to conﬁrm both are functioning properly.
Try a diﬀerent HDMI cable (2 meters or longer). HDMI.ORG stipulates that 2-meter or longer cables be used to connect any two HDMI devices. This is to ensure HDCP handshaking is given the necessary time to complete its sequence (cable length factors into this timing process; shorter cables may hamper full data exchange). HDCP handshaking is repeated every 2-3 seconds during operation.
Use DIPSWITCH 3 to read the EDID from the display.

Serial Communication

For communication with the AC-AVDM-V3, connect a micro-USB data cable to the USB ISP port located on the rear panel. The Serial-to-USB is internal and the required drivers (universal CH340 driver) will automatically install once plugged in.

Set the Serial Communication protocols to:

Baud Rate: 57600
Bit Number: 8
Checksum/Flow Control/Parity: None
Stop Bits: 1

Warranty

The Basics
AVPro Edge warranties products it manufactures and sells when purchased directly from AVPro Edge or an authorized AVPro Edge reseller. Products are guaranteed to be free from manufacturing defects and in sound physical and electronic condition when shipped by AVPro Edge.
AVPro Edge has developed a warranty everyone can get behind. We wanted to remove all warranty “red tape” to make it simple. Our 10-Year, NO BS Warranty is based on these 3 fundamentals:

If you are experiencing trouble, please call us. Our Tech Support specialists will make every troubleshooting attempt at a remedy while you are on the phone.
If it is determined the product has experienced an uncorrectable failure, we will provide an advanced replacement free of shipping charges, including no-charge return shipping for the unit on site.
We are conﬁdent that you know what you are doing and will never make you go through unnecessary troubleshooting steps with one of our products.

Coverage Details
AVPro Edge will replace or repair (at the customer’s choosing) any defective product. If the failed unit is out of stock or on backorder, replacement with a comparable product of equal value or feature set, if available, may be a viable solution. In rare circumstances, it may be determined repair is the only available option. Warranty starts upon receipt of the product (determined by conﬁrmed delivery via tracking). Should tracking information be unavailable for any reason, the warranty will have a start date coinciding with a thirty- day interval after receipt of the order (ARO).

Red Tape

AVPro Edge is not responsible to provide a warranty for untraceable purchases, or those made outside of authorized distribution channels.
If AVPro Edge determines a product has been modiﬁed or internally tampered with (as identiﬁed by a warranty seal violation and/or physical examination) or has an altered serial number, the warranty will be declared void. Additionally, physical misuse or damage incurred beyond normal installation standards and practices may violate the warranty. Warranties may also be prorated as a mutual means of reconciliation, after examination by an AVPro Edge representative.
Damage caused by “acts of God” (including, but not limited exclusively to): Natural disasters, power surges, electrical storms, earthquakes, tornadoes, sinkholes, typhoons, tidal waves, hurricanes, or other uncontrolled and unforeseen events related to unnatural weather conditions) are not covered.
Damage caused by incorrect installation will not be covered. Abnormal over- or under-voltage, inadequate cooling, improper cabling, lack of appropriate protection, and static discharge are many examples of improper installation, but warranty exclusions are not solely limited to these examples.
Warranty service for products installed or sold by an authorized AVPro Edge third-party reseller will be provided by that authorized AVPro Edge reseller. Accessories (items included in the original purchase, such as IR cables, RS-232 cables, power supplies, etc.) are not included in the warranty unless identiﬁed as the point of failure or the cause of performance that diﬀers from that intended by design.
We will make acceptable eﬀorts to source and supply replacements for defective accessories at a discounted rate as needed.
