Wiring and Connections
HDMI Cables
The AC-MX-44X uses standard 19-pin HDMI female ports for inputs and output connections.
Important things to consider when planning or installing this device:
• Ensure all HDMI cables and devices support the input signal. With 8K sources, ultra-high-
bandwidth/Ultra High Speed HDMI cables rated for 48 Gbps are recommended. For 4K and lower
resolutions, High-Speed HDMI cables with Ethernet rated for 18 Gbps are sufficient if all connected
devices are rated to handle the signal.
• Ensure HDMI cables are the correct length. AVPro engineers have determined that HDMI cables 2
meters and longer help eliminate EDID and HDCP issues associated with shorter HDMI cable lengths.
USB Ports
The device also has one USB Type-C port. This is a service port intended for AVPro Edge technical support if
troubleshooting or testing is required.
IR Wiring
IR connections are made using the provided 3.5 mm IR Emitter and IR Eye (receiver).
Ethernet/LAN
The NETWORK/LAN port on the rear panel communicates with the AC-MX-44X via a LAN, router, or third-party
control system processor and uses a standard RJ45 connector plug.
Type C
Stereo 3.5 mm (TRS) IR Eye Mono 3.5 mm (TS)
IR EmiGer
Page 12 of 35
AC-MX-44X User Manual
The recommended termination is based on the TIA/EIA T568A or T568B standards for the wiring of the twisted
pair cables. For TCP/IP control, commands use Telnet port 23.
RS-232 Control
The RS-232 control port on the rear panel allows a computer or third-party control system to communicate with
the AC-MX-44X.
Serial control connections are made using the provided 3-pin Euroblock connector. Insert the wire into the
appropriate hole, then secure it by tightening the screw located at the top of the connector.
Wiring for this port uses a 3-pin Euroblock-to-DB9 connector, where only pins 2, 3, and 5 are used. If the control
devices do not have a DB9 port, a USB-to-DB9 adapter may be required.
For RS-232 control, use a null modem serial cable adapter and set the serial communications to:
Baud: 57600, no parity, 8 data bits, 1 stop bit, with no handshaking.
Add a carriage return (Enter key) after each command when using direct commands. The unified command list
(ASCII) can be found here.

Setting the LCD Timeout to Always On may shorten the
lifespan of the LCD screen or result in image burn-in.
Cloud Services and Firmware Updates
Cloud Services allows OTA (Over-the-Air) firmware updates to be performed on the unit. This allows the unit
to search the Cloud for the latest firmware versions and enable third-party remote management services. If
the Cloud Services setting is turned off, the unit will opt out of any previously enabled services and will not be
able to access OTA firmware updates.
NOTE:
When updating firmware, some settings and configurations may revert to their original factory
default settings and may need to be re-applied after the updates are complete. It is always recommended
that settings and configurations are backed up before updating firmware.

Troubleshooting
• Verify Power – Ensure the power supply is connected correctly and on an active circuit.
• Verify Connections – Ensure all cables are securely connected and properly terminated.
• Verify Current Versions—Ensure that any firmware/software/driver updates are available for the devices.
• No Sound—Verify that the signal being sent is compatible with the connected devices in the signal chain.
Ensure the device’s volume level is properly adjusted and not set to mute. If a signal is present from the
input source, the selected output(s) will have a visible red optical light that can be seen from the TOSLINK
port.
• Static, Buzzing, or Humming Noises - Use shielded RCA cables between the AC-MX-44X and analog devices
to reduce noise. Make sure the matrix is grounded to metal components like racks or conduit. This helps
prevent ground loops, which can cause unwanted audio buzzing or humming.

Warranty
The Basics
AVPro Edge warranties its products purchased from Authorized AVPro Edge Resellers or direct purchases.
Products are guaranteed free from manufacturing defects and in sound physical and electronic condition.
AVPro Edge has developed a warranty that anyone can support. We wanted to remove all the “red tape” from a
warranty and make it simple. Our 10-year NO-BS warranty hinges on three elements:
• If you are having trouble, call us. We will attempt to troubleshoot your issue over the phone.
• If it’s broken, we will replace it in advance on our dime and cover the return shipping. Repair is an
option, too, but that is YOUR call.
• We know you know what you are doing. We will not make you go through unnecessary steps to
troubleshoot an extender…
Coverage Details
AVPro Edge will replace or repair (at the customer's choice) any defective product within the warranty period. If
the product is out of stock or on backorder, it can be replaced with a comparable product of equal value/feature
set (if available) or repaired.
Your warranty begins upon receipt of the product (as confirmed by the shipping firm's tracking). If tracking
information is unavailable, the warranty will commence 30 ARO (After Receipt of Order). The coverage continues
for 10 years.
Red Tape
AVPro Edge is not responsible for untraceable purchases or those made outside an authorized channel.
If we conclude that a product or serial number has been tampered with, as identified by the warranty seal or
physical examination, the warranty will be void. Additionally, excessive physical damage (beyond normal wear
and tear) may result in the warranty being voided or prorated based on the extent of the damage, as examined
by an AVPro Edge representative.
Damage caused by “acts of God” is not covered. These can include natural disasters, power surges, storms,
earthquakes, tornadoes, sinkholes, typhoons, tidal waves, hurricanes, or any other uncontrollable event related
to nature.
Damage caused by incorrect installation will not be covered. Examples include an incorrect power supply,
inadequate cooling, improper cabling, inadequate protection, and static discharge.
The Authorized AVPro Edge Reseller will service products installed or sold by a third party to AVPro Edge. The
warranty does not include accessories (IR Cables, RS-232, Power Supplies, etc.). We will make acceptable efforts
to source and supply replacements for defective accessories at a discounted rate as needed.

Obtaining an RMA
Dealers, Re-sellers, and Installers can request an RMA from the AVPro Edge Tech Support Rep or their Sales
Engineer.
You may also email [email protected] or fill out the general contact form at avproedge.com/contact
End users may not request an RMA directly from AVPro Edge and will be referred back to the Dealer, Re-seller,
or Installer.
Shipping
For the USA (not including Alaska and Hawaii). Shipping is covered on advanced replacements for FedEx Ground
(some expressed exceptions may apply). Defective product return shipping is covered by AVPro Edge using an
emailed return label. Items must be returned within 30 days of receipt of the replacement product; after 30
days, the customer will be billed. Other return shipping methods will not be covered.
The returnee will be responsible for the shipping costs for International (and Alaska and Hawaii) returns. Once
the unit is scanned for return shipping, AVPro Edge will ship the new unit for replacement.
Limitation on Liability
AVPro Global Holdings LLC's maximum liability under this limited warranty shall not exceed the actual purchase
price paid for the product. AVPro Global Holdings LLC is not responsible for direct, special, incidental, or
consequential damages resulting from any breach of warranty or condition or under any other legal theory to
the maximum extent permitted by law. Taxes, Duties, VAT, and freight forwarding service charges are not
covered or paid for by this warranty.
This warranty does not cover obsolescence or incompatibility with newly invented technologies (after the
product's manufacture).
Obsolescence is defined as:
“Peripherals are rendered obsolete when current technology does not support product repair or re-
manufacture. Obsolete products cannot be re-manufactured because advanced technologies supersede original
product manufacturer capabilities. Product redevelopment is not an option because of performance, price, and
functionality issues.”
Discontinued or out-of-production items will be credited toward a current product of equal or comparable
capabilities and cost at fair market value. AVPro Edge determines fair market value.
Exclusive Remedy
This limited warranty and the remedies above are exclusive to the maximum extent law permits, instead of all
other warranties, remedies, and conditions, whether oral or written, express or implied. To the maximum extent
permitted by law, AVPro Global Holdings LLC expressly disclaims any implied warranties, including, without
limitation, warranties of merchantability and fitness for a particular purpose. If AVPro Global Holdings LLC
cannot lawfully disclaim or exclude implied warranties under applicable law, all implied warranties covering this
product, including merchantability and fitness for a particular purpose, shall apply to this product as provided
under applicable law.
This warranty supersedes all other warranties, remedies, and conditions, whether oral or written, express or
implied.
