1. INTRODUCTION
Thanks for purchasing the FSR Magellan MAS 4100A, a 4x1 audio and video switcher with integrated
scaling. In addition to scaling switchers, such as the MAS-4100, FSR offers a full line of interfaces, line
drivers, distribution amplifiers, down converters, power sequencers and more.
The new Magellan MAS-4100Ais a 4x1 audio and video switcher with an integrated scaler. The
MAS-4100A automatically sizes and positions the incoming video signal and then scales the image to
the user selected output resolution. The Magellan MAS 4100A converts Composite Video, S-Video
and YCbCr Component Video signals to a variety of computer and HDTV resolutions. The unit
accommodates most worldwide NTSC, PAL and SECAM TV standards and has many features to
enhance performance. Standard VGA resolutions are supported up to 1024x768 as well as 480p, a
16:9 aspect ratio image at 852x480. These units also feature balanced stereo audio switching with
audio following video.
Several advanced techniques are incorporated into the scaling engine to provide the best possible
scaled output. The 3:2 pull-down detector automatically detects images that began as film. Since
these images began their life at 24 frames per second, and standard video signals are 30 frames per
second, a special algorithm is invoked to provide clear, fluid motion. In addition, a multi-line vertical
filter eliminates artifacts caused in the de-interlacing process. Static images are also processed using a
simple field merging technique to perform de-interlacing and it is very beneficial for static images or
scenes with very little or no motion.Additionally, the MAS 4100Aemploys a high quality Comb
Filter Decoder for maximum picture quality.
The MAS-4100Ais an advanced scaling switcher, but has been made very easy to use. All set-up and
operation controls are on the front panel. In addition to source selection, all of the image attributes
including, brightness, contrast, H-phase and V-phase, tint and color are accessible from the front
panel with easy to use on-screen menus. The unit may also be controlled remotely via an RS-232
connection and supplied software or a control system. The connections on the back are just as easy.
The MAS-4100Aaccepts composite video on a BNC, S-Video on a mini-DIN, and computer video
on an HD-15 connector. The output format is user selectable as either RGBHV or YCbCr. Both HD-
15 and BNC connectors are provided for maximum flexibility. Only one of these is active at any time.
The balanced audio is available on a 5 position pluggable screw terminal and can easily be interfaced
to balanced or unbalanced audio systems.

APPLICATIONS
Getting the Best Results
There are many factors affecting the quality of results when Composite or S-Video signals are
converted to computer resolutions. Some basic precautions will ensure the best possible performance
from your MAS 4100A Switcher/Scaler.
Output display device – The quality of the output signal will depend largely upon the type
and quality of display device used. For instance, some video projectors just look better than
others.
Distance between the Video Scaler and the display device – This plays a major role in the
final result. Long distances are possible, but special measures should be taken in order to
avoid cable losses. These include using high quality (coax-type) cables or adding cable
equalizers such as the RGB-HV-2 or the CDA-2EQA.
Output connection cables – Low quality cables are susceptible to interference. They
degrade signal quality due to poor matching and cause elevated noise levels. Therefore, cables
should be of the best quality. Coax-type computer cables are recommended because of their
superior internal shielding characteristics.
Interference from nearby electrical devices– These can have an adverse effect on signal
quality. For example, an older computer monitor often emits very high electromagnetic fields
that can interfere with the performance of video equipment in its proximity.

5. TROUBLESHOOTING
If the recommended actions listed below do not result in satisfactory operation, please
consult your Dealer or contact the FSR Technical Support Department directly by phone
at 973-785-4347 or by email at [email protected].
Problem Possible Solution
No picture on
the output
monitor.
Colors appear
wrong on the
output monitor
Too much
smearing
No color on the
output monitor,
only a black and
white image
None of the controls
appear to function
If pressing the power switch does not cause the
power LED to light, check that the proper AC Power
Cord is properly connected. If the Power LED is
illuminated, check that there is a correct Video Input
signal and that the display device connected to the
output is switched on and set to the correct input and
its Brightness and Contrast are set correctly. Check
to make sure the unit has been switched to the
correct output pin mode – HD15 or BNC.
Try adjusting the Color, Tint, Contrast and Brightness
settings on your display. These are usually set up for
viewing computer images, which may be somewhat
different from viewing images that have been up-
converted from video. Make sure the correct output
format is set (RGBHV or YCbCr). Make sure your
output cable assembly is not faulty, which could
prevent either the Red, Green or Blue signal from being
passed through the cable.
Smearing usually occurs when a Composite Video input
is used and is generally unavoidable, unless you can
switch to using S-Video. Using good quality video cable
will help towards reducing this affect. Smearing that
may not be noticeable on a small video monitor may
become objectionable on a large screen video projector.
Check the condition of the cables being used. A faulty S-
Video cable can often cause a black and white image.
Ensure that the color controls on your computer monitor
or video projector are all set correctly. Ensure that the
color adjustment on the Video Scaler is not adjusted
completely down. It may be necessary to reset the video
levels via the Menu functions.
The ON SCREEN DISPLAY (osd) has been turned off and
the front panel has been locked out. Just depress both the +
and - buttons for 3 seconds to unlock the front panel and then
the osd will be enabled.

quential damages, so the above limitations may not apply to you. This warranty gives you
specific legal rights, and you may also have other rights which vary from state to state.
Warranty claims should be accompanied by a copy of the original purchase invoice
showing the purchase date (if a Warranty Registration Card was mailed in at the time of
purchase, this is not necessary). Before returning any equipment for repair, please read the
important information on service below.
8. SERVICE
Before returning any equipment for repair, please be sure that it is adequately packed and
cushioned against damage in shipment, and that it is insured. We suggest that you save the
original packaging and use it to ship the product for servicing. Also, please enclose a note
giving your name, address, phone number and a description of the problem.
NOTE: all equipment being returned for repair must have a Return Authorization
(RMA) Number. To get a RMA Number, please call the FSR Service Department (973-
785-4347). Please display your RMA Number prominently on the front of all packages.
