TROUBLESHOOTING
Generally, the majority of HD distribution installation
issues are either caused by minor connection
errors, communication problems between devices,
or when the transmission of high signal bandwidth
is attempted using insufficient cable. Should you
encounter any technical difficulties when installing
and configuring the matrix, we are confident
solutions can be found by working through the
following troubleshooting checklist before seeking
alternative technical support.
No Picture or poor quality picture
1) Power – are all AMPs, HDBaseT transmitters or
display receivers installed powered both ends? All units
should have their own power source i.e. 18v for the AMP-
001-010 and 5v for 70m.230ft HDBaseT Transmitters and
Receivers – Please use power supplies included.
Note: Display receivers do not need to be independently
powered if part of an HDBaseT PoH extender set or MX-
PP-POH Matrix solution – there is a two-core power link
between transmitter and receiver that powers the receiver
at thedisplay end. Non-PoH display receivers can also be
powered via the display USB port by using the USB to 5v
power cable also supplied with this model.
Are all sources definitely powered and firmly connected?
2) If possible, always use test equipment prior to
installation and to troubleshoot any problems.
3) Distance – Is the cable too long for the signal to be
transmitted effectively? The HDBaseT classification used
within the AMP-001-010, transmitters and receivers allow
transmission of 1080p up to 70m/230ft so make sure
the cable distance matches the project requirements and
is well within the maximum transmission distance of the
signal.
Note: If approaching the limits of the transmission
capabilities, transmission should be extended by using
another AMP or receiver to ensure the signal reaches its
destination effectively.
4) Cable Joins – Joins in the cable run or RJ45
connectors can impact on signal strength, resulting in
reduced transmission that may manifest itself in incorrect
picture quality, picture dropping out or a complete lack of
picture
5) Cable Choice and Signal Reduction – Are stranded
patch leads being used as interconnects between patch
panels or wall outlets? CCA (Copper Clad aluminium)
cables being used? These can reduce transmission
rates by up to 40% – we recommend solid core straight
through with minimum connections used wherever
possible.
6) Resolution: Speckles noticed in the picture – If
the resolution of the source is reduced, is the result a
clean and stable picture? If so, this could suggest a
discrepancy between source and display resolution or
a bandwidth capacity issue with the cable. Check that
inputs and outputs share the same resolution and that
thesignal is being successfully transmitted along the cable
run.
7) Correct connection – It may seem obvious but
double check all UTP, HDMI, power and IR cables are
connected to the correct ports.
Note: Even a fraction off can be the difference between
aperfect picture and a blank screen. Double check all
connections are firmlymade in the correct ports.
