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.
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.
The AC-AVDM-V3 supports decoding of Dolby
®
and DTS
®
formats, outputting single-ended analog stereo audio,
digital (LPCM 2.0) over HDMI or S/PDIF (optical and coaxial).
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.

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:
o Bypass the AC-AVDM-V3 and plug the source directly into the display to confirm both are functioning
properly.
o 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.
o Use DIPSWITCH 3 to read the EDID from the display.

Place of purchase
Details of the issue and any conditions under which the issue is occurring
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.

background
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.
Obtaining an RMA
Dealers, resellers, and installers can request an RMA (Returned Merchandise Authorization) from an AVPro Edge
Technical Support rep or Sales Engineer. Or you may email
[email protected] or fill out the general
contact form at
www.avproedge.com/contact.
End users may not request an RMA directly from AVPro Edge and will be referred back to the dealer, reseller, or
installer.
Shipping
For the USA (not including Alaska and Hawaii), shipping is covered for advance replacements using FedEx
Ground (some Express exceptions may apply). Defective product return shipping is covered by AVPro Edge,
using a return label issued via email. Items must be returned within 30 days from receipt of the replacement
product. At 40 days, the customer account will be billed. Other return shipping methods will not be covered.
For international (and Alaska and Hawaii) return shipping costs will be the responsibility of the returnee. Once
