FAQ’S
which may solve any colour problems. If not, try changing
the HDMI cable between the source and the matrix to rule
out defective cabling.
No sound or poor quality audio
Audio is transmitted within the video signal – there
is no separate audio track – so generally a problem
with sound will be accompanied by a problem with
picture. However, if technical issues with audio are
experienced, the cause is typically communication
between sources, displays and/or AV receiver
settings.
1) Have specific speaker sets or zones been
enabled? Some AV receivers allow individual speaker
selections assigned to specific zones in the set up so
check the speakers used are fully connected to the
amplifier and correctly assigned within the system set up.
It may be an EDID issue in that the source reads the audio
EDID from the display and only requests two channel
audio and EDID copy from the AVR may be required or
use an embedded EDID in the matrix.
Note: If problems are experienced when an AV
receiver is used, the cause is usually the settings
of the AVR itself. Refer to the AVR manufacturer’s
guidelines on the correct settings to use for your
requirements.
2) Consistency of audio output between devices – Is
there any discrepancy between the audio output of the
source, the audio or zonal settings of the AV receiver and
the speaker configuration used needed for successful
audio replication? If outputting 7.1, make sure all devices
connected are also outputting 7.1
Note: Occasionally with some sources, the device
settings allow the specification of audio output
through a TV or an HDMI port. If using an AV
receiver, check the HDMI output option is selected.
3) Do all the local sources work through the
AV receiver? Check the operation of each source
individually.
Bandwidth
1) If using a graphics-based source (such as a PC/Mac/
media server), make sure the source resolution is set to
a maximum of 1080p, 60Hz. Higher resolutions available
for graphics-based systems require higher bandwidth
that may affect transmission of signals as well as
incompatibility with devices.
IR
1) Check you are using emitters at the IR TX
transmitter end and receivers at the IR RX receiver
end – are they connected to the correct ports on the
matrix and display receiver.
2) Is the emitter correctly positioned on the source?
Fix the emitter directly over the infrared sensor of the
source and attach using the adhesive backing.
Note: Locate the infrared source sensor by using a
flashlight to find s small sensor within the facia of the
source display. If necessary, secure the emitter over the
sensor with a small amount of contact adhesive.
3) Is your remote powered and sending a signal?
Note: IR is invisible to the naked eye, so use a digital
camera/ phone camera to check the remote signal – point
the camera at the remote control when pressing a button.
You should see the remote transmitter flashing to indicate
a signal being sent. Replace batteries if flashing is not
seen on the digital camera screen.
4) IR dropout issues can be due to exterior influences
emitting infrared radiation that can interrupt IR signals.
Ensure emitters and receivers are away from the following
causes of IR interference.
• Direct sunlight
• Halogen lighting
• Plasma screens
6) UTP Termination Issues – ensure cables and RJ45
terminations are correct and in good condition at
both transmitter and receiver ends to see if control is
established. If so, a possible re-termination of the cable
could remedy the problem.
7) Are WyreStorm emitters and receivers being used?
The use of third party products/magic eyes may not be
compatible. Always use WyreStorm components included
with your purchase or check compatibility of third party
control systems with your WyreStorm dealer.
8) If problems persist, swap out the IR emitters and
receivers to rule out faults with the units themselves. Use
emitters you know are fully operational to test working
condition.
9) Reactivate the IR callback function on your matrix and
swap IR ports on the matrix to rule out a fault with the
matrix or connection ports.
