The AC-MX88/44-AUHD is a true 4K60 4:4:4 8x8/4x4 HDMI matrix switch. Supporting HDMI 2.0, HDCP 2.2, HDR and
up to 18 Gbps bandwidth. This switch allows any source (Blu-ray, UHD Blu-ray, satellite receiver, game consoles,
PCs, etc...) to be shown on any of the connected displays.
Audio Delay is “On-Board” so lip-sync issues are able to be managed before they become a problem. Also, with built-in scalers
there is no need to forfeit 4K signals just because there are a couple of older displays. Additionally, full EDID
management allows maximum flexibility with today's wide mixture of sources and displays.
This matrix equalizes and amplifies the output to ensure that HDMI signals can be transmitted through long HDMI
cables without loss of quality. For long runs, stretch your distance further with the AC-EX70-UHD or AC-EX40-444
HDMI Extenders.
This is an ideal solution for digital entertainment centers, HDTV retail, show sites, data centers,
schools, conference and training centers and more!

Device Overview:
•Definition - Matrix switches provide the ability to route any input to any output or to multiple outputs at any time.
Depending on the model, a matrix switch can route HD, UHD or AUHD content in this manner. Additionally, since
most venues have both, audio zones and video zones, the requirement to breakout or strip off the audio is often
necessary and has become almost a standard feature on most matrix switches.
•Control – Matrix switches are generally controlled via a third-party controller (like Control 4, RTI, Crestron, etc...).
Many integrators want ready-made drivers for their control system in order to make programming and
deployment easier.
•Matrix Switches are widely used in both, Commercial and Residential Applications.

Figure 1 –Switching with the front panel controls. NOTE: Select the OUTPUT and then the INPUT.
Scaler Control:
The AC-MX88-AUHD-GEN2/AC-MX44-AUHD has scalers built into every output. The scalers are set on
the OUTPUT side of the switch and each can have separate settings. Control the scaler in four ways:
• HD-4K (Scales 1080P to 2160P)
• 4K-HD (Scales 2160P to 1080P)
• AUTO (Automatically detects capabilities of attached display)
• BYPASS (There will be no scaling set)
*NOTE: There is additional control when using the web interface. Also, with LAN control, you
can set HDBT-C mode, which reduces 10-18Gbps content to 9Gbps for legacy infrastructures.
This mode maintains 4K resolution, but removes HDR.

Audio Delay Control:
The AC-MX88/44-AUHD has an Audio Delay feature built-in. Audio Delay is set on the extracted audio
OUTPUT (Digital and Analog) of the switch and each can have separate settings. The Audio Delay has
4 controls:
• UP (Increase Delay)
• Down (Decrease Delay)
• MUTE (The audio will be muted)
• BYPASS (There will be no delay set)
*Delay settings are in increments of 90 milliseconds. Settings are: 90MS, 180MS, 270MS, 360MS,
450MS, 540MS or 630MS.
Control this feature from the front panel:
1. Press and hold the OUTPUT number for which you want to delay the audio.
2. The available options will light up (as pictured).
3. Press UP, DOWN, MUTE or BYPASS to control the delay.
4. The current setting will be indicated on the LCD screen.
Audio Output Logic and Cable Prep:
You can extract audio from toslink or balance 2CH Audio. Audio outputs are an un-decoded output. This
means that what goes in, is what goes out.
2CH Balanced Audio Port - Supports 2CH PCM audio only, which is ideal for 2 Channel systems and zoned
audio systems.
Toslink Audio Port - Supports PCM, LPCM (up to 7CH), Dolby Digital, Dolby Digital Plus, DTS, DTS-HD, DTS
Master Audio, which is ideal for multi-channel audio systems and older AVR's that do not support 18Gbps.
Need to down-mix for combination, uncompressed and 2CH systems? Check out the AC-ADM-AUHD and
AC-ADM-COTO.
You can use balanced analog outputs in a balanced system, but you can also prep a cable as shown below to
convert to a traditional 2CH unbalanced (L/R) system. You can also purchase pre-made cables (AC-
CABLE-5PIN-2CH) at www.avproconnect.com.

•Invalid/incorrect EDID coming from display. When Cascade Mode is ON, EDID is managed at
the switch and down stream EDID will be completely ignored.
•If you have a display or projector that has difficulty changing between resolution or in and
out of HDR, Cascade Mode can stabilize the project.
•Any flashing and instability from devices in the system when running one or more outputs
into additional peripherals before the display
Since sync time will increase slightly, we recommend you ONLY use cascade mode if you have
exhausted all other troubleshooting options.
To toggle Cascade Mode press and hold (3 seconds) INPUT 1 and INPUT 2 at the same time. When
Cas
cade Mode is enabled you will see this:

EDID Management:
This matrix has 29 factory defined EDID settings. It also has 3 user defined EDID memories. The user EDID
memories are independent to each input and can be set differently. The user defined EDID can be uploaded using
the free PC Control software or RS-232. In addition, you can choose to read the EDID from the desired output and
the captured EDID will automatically store and overwrite the EDID in "USER EDID 1" and will be applied to the
selected source.
By default, the matrix is set to a 1080P EDID, this is to maximize plug and play capability. When using 4K sources,
you will want to define a 4K EDID on each input (or read from the display).
To Change the EDID setting:
1. Press and hold (for 3 seconds) the INPUT you want to change.
2. The “UP” and “DOWN” button’s will illuminate (
as pictured below), and the LCD will show the
active EDID.
3. Toggle through the EDID options by pressing up or down repeatedly.
4. Press the “INPUT” you had selected in order to apply the EDID (this will still be illuminated).
These are the pre-defined EDID settings that you can toggle through:

Quick Network Connect to Web Interface:
Use the following steps to quickly and immediately connect to the matrix switch:
1. Connect the LAN port into an active router port.
2. On most networks you can simply type the Default IP address into any web browser. The Default IP Address is
192.168.1.239.
If you are on a closed network or non-standard, the following may work better when using DHCP:
1. Use an Ethernet cable to connect the LAN port on the switch to an unused, active port on the router.
2. Enable DHCP by pressing the INPUT 1 and INPUT 4 buttons simultaneously for 3 seconds.
3. Wait 5 seconds, then press and hold (for 3 seconds) the INPUT 3 and INPUT 4 buttons simultaneously. The
display will show the assigned IP address.
4. Input the IP Address into any web browser.
Setting a Static IP:
•Once connected, you can use the web interface to set a static IP address.
•A static IP can also be set by using the RS-232 software or a direct command (see RS-232 below for more
information).

Web Interface: Video Setting
Video Scaler Modes:
With the video scaler mode, you can scale each HDMI output independently
•BP = Bypass - Scaler is disabled (Default)
•2K = 4K --> 2K - If incoming signal is 4K, it will be downscaled to 1080P or 1900x1200 depending on the input format.
•4K = 2K --> 4K - If the incoming signal is 1080P it will be upscaled to 4K.
•HDBT = HDBaseT Compatibility Mode - If incoming 4K signal is above 9Gbps, it can be compressed to fit through
legacy (non-18G) infrastructures. 4K resolution will still come through, but HDR will not.
•AUTO = Auto detect - Scaler will be set based on the connected display's EDID (ie, if the EDID is 1080P the scaler will
be set to 2K).
•W = Weak - Minimum level of enhancement
•M = Medium - Medium level of enhancement
•S = Strong - Strongest setting for image enhancement
•OFF = None - Feature disabled
Output Signal Generator:
The Output Signal Generator will output an internally stored 1080p color bar test
pattern (see the image on the right) to test infrastructure. It can be turned on and
off for each output, but remember to turn it off to resume normal functionality.
Image Enhancement:
The Image Enhancement feature will add extra sharpness to edges in the image. This effect may be desirable for presentations in
corporate or classroom environments. NOTE: Image Enhancement only works when upscaling from 2k to 4k.

Web Interface: Audio Matrix
Audio Matrix:
This allows the user to route the audio in a matrix fashion for the extracted audio ports.
NOTE: The Audio Matrix Function only works if "MATRIX" is selected on the right (See next explanation).
Ex-Audio Matrix Mode:
This allows the user to set a binded audio setting or set the extracted audio to Matrix. The options are:
Bind to Input - The extracted audio port is always fixed to a specific input. For example, when a source is plugged into
INPUT 1, OUTPUT 1 will always have the audio signal from INPUT 1. This will happen regardless of which input is
selected for OUTPUT 1.
Bind to Output (Default) - The extracted audio always follows the corresponding HDMI output. For example, in this
mode AUDIO OUT 1 and HDMI OUT 1 are the same (Switched Together).
Matrix - You can set to "Matrix" and it will allow routing of the audio as a separate, stand-alone "Matrix". This allows
use of the "Audio Matrix" buttons pictured above.

RS-232 Commands:
The AC-MX88/44-AUHD can be controlled with RS-232 commands. Some configurations can only be completed
by using these commands. We recommend using MyUART software (free of charge) as it is very easy to use in
order to send commands to the machine.
The same commands can be sent to the matrix using Ethernet as IP commands.
The serial port settings should be set to: 57600,n,8,1 (baud: 57600, no parity, 8 data bits and 1 stop bit) with no
handshaking.
Please add a return (Enter key) after each command when using direct commands.
The unified command list (ASCII) is listed below.
