Our Contractor CMX44AB 4K HDMI Matrix oers unprecedented
performance and value for the custom installation market. The CMX44AB
supports HDMI2.0 with HDCP2.2, allowing distribution of four HDMI sources
to four displays. This enables all sources to be viewed as required within
a matrix configuration. The unit transmits all HDMI resolutions up to and
including 4K 60Hz 4:4:4. The 4-Way matrix also includes audio breakout
and EDID management.
Introduction
FEATURES:
• Features 4x HDMI inputs which can be independently routed to 4x HDMI outputs
• Supports 4K UHD video including HDR (up to 4K @60Hz 4:4:4)
• Independent video down conversion on all HDMI outputs allowing a display only capable of supporting
lower 4K video resolutions (4K 60Hz 4:2:0) to receive 4K 60Hz 4:4:4 video content while still showing
maximum original 4K UHD resolution on remaining outputs
• Supports all industry standard video resolutions including VGA-WUXGA and 480i-4K
• Supports all known HDMI audio formats including Dolby TrueHD, Dolby Atmos, Dolby Digital Plus and
DTS-HD Master Audio transmission
• HDMI audio breakout to associated output analogue L/R audio and coaxial digital outputs concurrently
• Control via front panel, IR & RS-232
• 3rd party drivers available for major home control brands
• Advanced EDID management
• HDCP 2.2 compliant

The Blustream CMX44AB Matrix can be controlled via a 9-pin serial cable.
For the full list of protocols please see ‘CMX44AB Control Protocols’ located at the
rear of this manual.
Details of RS-232 pin assignment and communication are adjacent. Please note
that depending on your control device serial port pin configuration you may
require either a ‘Straight’ RS-232 cable or ‘Null-modem’ type.

CMX44AB USER MANUAL
08 www.blustream.co.uk
The CMX44AB features an automatic video resolution down-conversion tool allowing for the matrix to convert the chroma
subsample of the native video source signal to a lower format of the same resolution.
Where the matrix is fed with a source signal that is (for instance) 4K 60Hz 4:4:4 but any screen connected to any of the 4 HDMI
outputs cannot accept this native chroma subsample, the matrix will automatically convert the signal to 4K 60Hz 4:2:0.
Please note: The CMX44AB matrix cannot automatically down-convert a 4:2:2 chroma subsample.
Automatic Video Resolution Conversion
The EDID configuration of the CMX44AB can be altered per input by using serial commands per the API details towards the rear
of this manual, or using the supplied remote control (details on page 7).
Please note: The 4K auto down-conversion feature will read the EDID from the display and output a suitable 4K video
resolution. The EDID handshake will not know if the method of HDMI signal distribution between Matrix and display is capable
of supporting all 4K resolutions. It may be necessary to use EDID management to lower the source resolution to support the
method of signal distribution required, especially if the displays being used are only capable of 1080p (or lower) support.
Adjusting EDID Settings
Audio Breakout
The CMX44AB Matrix includes audio breakout from the selected HDMI zone output to associated analogue L/R audio and coaxial
digital outputs. Extracted audio will be concurrent with the corresponding HDMI video output.
1. Coaxial digital output - Output 2
2. Analogue pre-amp line level output 3.5mm stereo jack - Output 2
Please note: The CMX44AB Matrix does not downmix multi-channel digital audio signals.
