INTRODUCTION
Congratulations on your purchase of the Marmitek MegaView20. The
MegaView20 is a programmable modulator which converts audio- and
video signals of for instance your DVD-player, satellite receiver, VCR, surveil-
lance camera, decoder, set top box or PC and adds them as an extra TV

channel on your antenna cable. Then you can watch this signal as a kind of
internal TV-channel everywhere in your home assumed there is an antenna
connection.
The Marmitek products are manufactured with the utmost precision and are
of high quality. Please read this manual first and follow the instructions so
you can enjoy the possibilities of this product optimally.
1. APPLICATION AND OPERATION MEGAVIEW20
The antenna cable is, as you could say, looped into the modulator. The
incoming antenna signal is connected to the antenna connection, besides
that you can connect an A/V device of your choice to the input on the
MegaView20. The outgoing antenna signal then carries both the standard
antenna signal and the added Audio/Video-signal (of for instance a DVD-
player or AV-camera). On every TV connected to this antenna system after
the modulator (‘To TV / RF OUT’ of your MegaView20) the added
Audio/Video-signal can be watched on the selected channel. You do not
need to make any changes to the rest of your antenna network.
The modulator itself has no influence on the strength of the signal. The
maximum length of the cables to be used is determined by the present
cable network in your home. If you want to connect multiple TV sets or
want to use a longer cable, we advice you to use an amplifier/splitter. Your
antenna material supplier can advice you in this.
2. CONTENTS OF THE PACKING

1x MegaView20 modulator
1x Power adapter
1x IEC Antenna cable (1 metre)
1x Manual
3. CONNECTING THE DEVICE TO THE MEGAVIEW20 MOD-
ULATOR
Switch off all devices before you start connecting. Then connect the device
you want to connect (for instance the DVD-player or AV-camera) to the
MegaView20. You can connect the device with a SCART cable or a cinch
cable. Use one of the two possibilities mentioned below.
Connecting an A/V appliance via SCART (1)
You can use the ‘SCART connection’ on the modulator to add the video-
and audio signal desired to the antenna signal. You can use a SCART cable
(not included) and you connect this to the ‘SCART IN’ of the MegaView20.
Tip: See chapter 6 Extra options for the possibility to connect
multiple devices
Connecting an A/V appliance via cinch cable (2)
Any so called composite audio- and video signal can be connected to the
modulator. For this you can use a cinch cable (not included). Make sure the
colours of the plugs and the sockets are corresponding. That means red to
red, white to white and yellow to yellow.

A/V appliance via SCART to TV (3)
The ‘SCART OUT’ connection on your MegaView20 offers you the possibili-
ty to connect not only the signal of your A/V devices to the antenna signal,
but to also loop it to a TV set via SCART (for instance for TV sets that are
not connected to your antenna network).
Attention: This connection only transfers the A/V signal of the con-
nected device back to the TV set and not the other TV channels.
4. CONNECTING THE ANTENNA SIGNAL TO THE
MEGAVIEW20 MODULATOR
Follow the description below to connect the antenna cable.
Connecting an antenna cable (4)
Connect the existing antenna cable to the ‘ANT/RF IN’ connector of the
MegaView20. Depending on the current situation you may need to discon-
nect some of the cables before you can connect the antenna.
Connecting an antenna cable to TV (5)
Connect the ‘To TV/ RF OUT’ of the MegaView20 to the antenna port of
the television set (if necessary with the use of included antenna cable).
If you want to watch this signal at multiple places, you connect a splitter
between the MegaView20 and the TV (your supplier of antenna materials
can advice you in this). On every television connected to the antenna sys-
tem after the modulator the added audio/video signal can be watched on
the selected channel (see display).

Tips:
• Make sure the connectors are fitted properly to the coax cable.
• Use high frequency shielded connectors to prevent radiation and
interference.
• Use only broadband amplifiers and splitters with a range of 5-
1000 MHz.
5. SELECTING THE CHANNEL
The added Audio/Video-signal (of for instance a DVD-player or AV-camera)
is converted into a normal TV-channel.
With the MegaView20 you can actually choose every free channel. It is
important to choose a free channel, which is not yet in use by an existing
TV-channel. Which channels are free depends on the incoming antenna sig-
nal. For this, consult the channel chart provided by your cable company, or
if you have your own antenna, the channel overview in your TV-guide.
1. Connect the power adapter to the modulator and plug this in the sock-
et. Turn on the modulator by switching the ON/OFF switch to ON.
2. Take your channel chart and look for two free adjacent channels. Then
you choose the higher of these two channels. Example: when channel
37 and 38 are free, you should choose channel 38. With three free
adjacent channels, you should choose the middle one.
3. Use the CHand the CHkeys on top of the modulator to select the
chosen channel. The illuminated digital display on top of the panel
shows this channel.
4. Now switch on the desired A/V device (DVD, VCR, satellite receiver, PC,
camera, etc.).
5.
Turn on the TV, and find the selected channel. How to do this can be read
in the manual of your TV. If you cannot select channels on your TV set,
but only frequencies, you can look this up in the enclosed table in the
back of this manual. This set channel now shows the connected A/V
device and from now on you can watch this on the channel you selected.

6. Now check if there is no interference on the TV-channels close by. If
there is, you need to find two (or if possible three) other free channels
and set the modulator to that one.
If you have multiple TV sets in your home (connected to the same antenna
network), then you can watch this signal on the other TV sets as well.
However first you need to set the right channel on every TV.
6. EXTRA OPTIONS
Infrared extension
Do you want to operate your DVD-player or satellite tuner in the living
room from your bedroom? Or operate devices in a closed cabinet?
Marmitek infrared extenders make sure that the signal of your remote con-
trol goes right through cabinet doors, walls and floors.
• The VideoControl3 sends the signal of your remote control back to
another room via the existing antenna cable.
• Right through walls and ceilings with your existing remote control? This
is possible with the PowermidXS. The wireless solution for extending
the signal of your remote control!
Connecting multiple devices
• Do you want to connect multiple A/V devices? With the Connect 236
you can connect all of your devices to your MegaView20 with just one
cable, preserving the quality.
• You can also connect a second A/V device using a second
MegaView20. By selecting another TV channel on it you can watch
both devices at different places.
A/V Camera
Do you want a more comfortable and safer feeling in and around your
house? With the MegaCam1 you can keep an eye on your house, garden,
garage and driveway. Connect this to your MegaView20 and you can watch
these images on TV in various rooms in your house.

nel. Choose another channel for the MegaView20 (preferably the middle
one of three or if possible five free channels).
