If the image does not appear or there is no sound
1. Make sure that all the devices are powered on.
2. Ensure that the connectors are wired correctly at both
ends of the cables. Audio cables must be wired for an
unbalanced stereo input signal and for a balanced or an
unbalanced stereo output signal.
3. If input is from a laptop computer and no picture
appears, use a laptop breakout cable for the input
connection. Check the computer’s user ’s guide or
contact Extron to determine if special commands are
required to output video to the external video port.
Also, many laptops’ screens shut off after the external
video port is activated.
4. Call the Extron S3 Sales and Technical Support Hotline
if the image still does not appear or there is no sound.
If the image is not displayed correctly
1. If the picture is too bright or dark, or if the edges of the
image seem to exceed their boundaries, or if thin lines
and sharp edges look thick and fuzzy, change the gain
setting.
2. If the picture appears and is stable, but it has ghosting
or blooming, verify that the video input is properly
terminated. If the problem is not resolved by changing
the termination, try using a different input cable. Poor
quality or damaged cable can cause ghosting or
blooming.
3. If the picture still is not displayed correctly, call the
Extron S3 Sales and Technical Support Hotline.
If the interface does not respond to horizontal shifting
1. If the picture does not move on screen when the
horizontal shift control knob is rotated, DDSP is in use.
Set the DDSP DIP switch to Off.
Once the system has been cabled and tested, the interface can
be installed in the wall or furniture. If optional AAP or mini-
AAP devices are being installed (RGB 468xi, RGB 468 Mxi,
RGB 478xi or RGB 478 Mxi only), see the following section
“Mounting the optional AAP device”. To mount the interface
to a wall box, see “Mounting the interface to the wall box”.
Mounting the optional AAP device
The interface and any optional architectural adapter plates
(AAPs) or mini-AAPs must be cabled before the interface is
installed in a wall or furniture. The screws needed for
installing the optional AAP devices are built into its front
panel and hex screws are provided with mini AAP devices,
so no additional screws will be needed.
1 . Before any cables are attached to an AAP device, secure
the optional AAP devices to the faceplate with the
provided captive washers and #4-40 nuts, or the 3/32”
hex screws (mini AAPs).
Mounting the optional AAP device (standard AAP
device shown)
2 . Follow steps 3 through 9 in the “Installation
Overview” section of this guide. For step 8
(mounting the interface to the wall box), see the section
on “Mounting the interface to the wall box”.
