Thank you for buying the Marmitek MegaVideo 55. Please read these operating instructions first in order to obtain maximum pleasure from your purchase. Please also carefully observe all the instructions for safe use of the product.

1. Safety precautions

•To prevent short circuits this product should only be used indoors and only in dry rooms. Do not expose the components to rain or moisture. Do not use near a bath, swimming pool etc.

• Only connect the transformer to the mains after you have ensured that the mains voltage matches that shown on the type plate. Never connect a transformer or mains cable if it is damaged. In the event of damage please contact you supplier.

• Never expose your system’s components to extremely high temperatures or bright light.

• Never open the equipment. Parts of the equipment have a very high voltage. Repairs or maintenance should be undertaken by qualified service personnel only.

All warranties are invalidated in the event of incorrect use, unauthorised modifications or repairs. Marmitek accepts no responsibility in the event of incorrect use of the product or if it is used other than for the intended purpose.

2. Use and operation of the MegaVideo 55

The MegaVideo55 is a programmable stereo modulator that converts audio and video signals from, for instance, your DVD player, satellite receiver, video recorder, security camera, decoder or PC and adds it to your aerial cable as an extra channel. Then you can receive this signal as a kind of internal TV channel anywhere in the house where you have an aerial connection.

You could say that the modulator is “looped into” the aerial signal. The incoming aerial signal is connected to the aerial input. The audio/video signal (from a DVD player for instance) is added to the outgoing aerial signal. The added video signal can now be viewed on the channel that has been set on any televisions that are connected after the modulator (on the ‘RF ANT OUT' side of your MegaVideo 55). You do not need to change any other part of your aerial network.

Thanks to the built-in “infrared return channel” you can continue to operate the connected appliances from other rooms using your own remote control. One infrared receiver is supplied as standard. Additional receivers can be purchased should you wish to operate your equipment from different rooms.

The infrared return channel only works with amplifiers, splitters and aerial wall outlets that are return channel compatible. Compatible components are usually marked ‘5 – 30 MHz’ or ‘5 – 68 MHz’. Your aerial specialist can provide more information on this. The modulator itself has no effect on the signal strength. The maximum length of cable that

3MEGAVIDEO55tm

can be used depends on the cable network in your house. If you want to connect a number of TVs or use longer cable lengths it is recommended that you use an amplifying splitter. Your aerial equipment supplier can give you advice on this.

4. Connecting appliances to the MegaVideo 55

modulator

Turn off all appliances before making any connections. Now attach the appliance you want to connect (e.g. the DVD player) to the MegaVideo 55. There are a number of ways to do this.

Using an RCA cable

All types of composite video signal and audio signal can be connected to the modulator. This can be done using the supplied RCA cable. Ensure that the plug and socket colours match each other. That is, red to red, white to white and yellow to yellow.

Using a scart cable

If the appliance you want to connect has a ‘scart connection’ you can use the supplied scart doubler. When this is used you do not loose the use of the scart connection, so it can still be used for other applications. When the MegaVideo 55 is connected to the scart doubler (using the RCA cables on the side) and the scart cable that was originally connected to your appliance at the same time, jumper E will have to be removed. The MegaVideo 55 ensures that picture quality is maintained.

Connecting a number of appliances

If you want to simultaneously connect several appliances to the modulator there are a number of ways to do this:

4 MARMITEK

Using a suitable A/V switcher

All of your appliances are connected to the A/V switcher. This option gives the best quality. A good A/V switcher (such as the Marmitek Flat TV Link 4, art. no. 09592) takes care of the correct modification of the signal.

Using a trio RCA splitter

(1x RCA to 2x RCA adaptors). In this case jumper E should be removed. The MegaVideo 55 optimises picture quality.

5. Connecting the aerial signal to the

MegaVideo 55 modulator

Two types of aerial plug are used in Europe: the IEC plug and the F plug. The latter has the least loss and is therefore often used in better quality systems. Your Marmitek MegaVideo 55 uses this type of plug. Check your situation below:

You are using F plugs

Connect the aerial cable coming from you aerial source to the input marked ‘RF ANT IN’. Then connect the aerial cable leading to the rest of your aerial network to the output marked ‘RF ANT OUT'.

You are using IEC plugs

Adaptors are supplied in case you are using IEC plugs. Then follow the same procedure as described above.

INFRARED EYE

Your connecting cables have not yet been fitted with plugs

In this case ensure that the plugs are correctly fitted to the coax cable. Use high frequency screened plugs to avoid external radiation and interference. Only use broadband amplifiers and splitters with a range from 5 - 1000 MHz.

Attention: If you want to use the infrared return channel for your remote control (see chapter 6) then the aerial wall outlets, amplifiers and splitters that are included IN the cabling between your bedroom and living room should be “return channel” compatible (5 – 30 MHz).

6. Setting the channel

The audio/video signal that has been added (e.g. from a DVD player) is converted into a normal TV channel.

Using the MegaVideo 55 you can, in principle, choose any free channel. It is important to select a free channel that is not already being used for an existing TV channel. The channels that are free depend on the incoming aerial signal. For details consult the channel table supplied by your cable company or, if you have your own aerial, the channel summary in your TV magazine.

1. Connect one of the two power adapters to the modulator and plug it into the mains.

2. Check your channel table and find two free channels that are adjacent. Now select the higher of these two channels. Example: if channels 37 and 38 are free then select channel

38. If three adjacent channels are free select the middle channel.

3. Set your selected channel using the dip switches on the front of the modulator.

The white dip switches can be set in two positions: ON (= 1, switch up) and OFF (= 0, switch down). The combination of switches determines the channel setting. It is easier to do this using a small screwdriver or a ballpoint pen.

You can find the correct dip switch positions for the channel you have selected in the table at the end of this manual. For instance, channel 38 would be 01100100. The 2nd, 3rd and 6th dip switches are ON (up) and the remaining dip switches are OFF (down).

Attention:

• The leftmost 7 switches (1 to 7 incl.) are for setting the channel.

• The 8th switch is used to turn the test picture on or off (up is on). That is why this switch is normally shown in the 0 position in the attached list.

• If there is a 9th switch it has no function.

4. After you have set the channel you can turn on a test pattern using the 8th dip switch. To do this set the dip switch to ON (= 1). This patter n consists of a number of black and white bars on the screen.

5. Turn on the TV and find the channel that you have set. Your TV’s operating instructions will tell you how to do this. You will now see the test pattern on the set channel. Now check that there is no interference on the neighbouring TV channels. If there is, you should select another two (or if possible) three free channels and set the modulator to these channels.

After you have done this set the 8th dip switch (test pattern) back to OFF. From now on you will be able to watch the attached A/V appliance on the channel that you have set.

6. Now turn on the required A/V appliance (DVD, video recorder, satellite receiver, PC, camera, etc.). You can now view the signal on the TV. If you have a number of TVs connected to the same aerial network then you can also view this signal on the other TVs. To do so you will first have to set the correct channel on each TV.

7. Setting the infrared return channel for using

remote control

An infrared receiver is supplied with the set. This receiver can be fitted between the TV and the aerial signal. The receiver converts the infrared signal from your remote control and sends this signal back to the modulator through the aerial cable.

Using the supplied infrared eye you can convert this back to an infrared signal and send it to the connected appliance. In this way you can operate the connected appliance (e.g. a DVD player) from another room.

It is easier to connect this if someone helps you.

1. Disconnect the aerial cable connected to the back of your TV. Connect this to the ‘ANT IN’ / ‘In’ connection on the metal part of your infrared receiver.

2. Reconnect the ‘TV OUT’ / ‘To TV’ side to your TV. You can use the supplied adaptors for this (F connector to IEC).

3. Position the red plastic part containing the infrared receiver where it can be seen from where you want to use your remote control. Avoid direct sunlight or light from a plasma screen.

4. Connect one of the two supplied transformers to the metal part of the IR receiver.

5. Turn the switch on the side of the red plastic part to the ON position.

6. Connect the supplied infrared eye to the side of the modulator, where it is marked ‘IR OUT’. The infrared eye has a self-adhesive backing. Remove the protective sheet and stick the eye carefully over the infrared sensor on your video recorder, DVD player or satellite receiver. This infrared sensor can usually be recognised by the dark coloured plastic window.

7MEGAVIDEO55tm

7. Point your own remote control at the infrared receiver and press a button, for instance one used to change the channel or select a different function. If all is well the attached appliance will now react. If not, then move the infrared eye and try again. The location in which the infrared eye responds can sometimes be very small. As soon as the function works correctly you can firmly attach the eye to the appliance. This will not damage your appliance.

8. Using infrared receivers in a number of rooms

If you want to operate your appliance from a number of TVs you can purchase extra infrared receivers (art. no. IH9211).

Frequency A is always supplied with the basic set. If you have more than one receiver with the same frequency ensure that only one of these receivers is switched on at any time (one receiver switched åON√ and the other receivers switched åOFF√). If you fail to do this your infrared commands will not be transmitted correctly.

Order information for individual infrared receivers:

Infrared receiver frequency A: Art. No. IH9211

Operating more than one appliance

If you want to operate more than one appliance by means of infrared you can purchase the IR EYE (art. no. IH9156). This model has 2 infrared eyes for, for instance, Video recorder and satellite receiver.

2. Anwendung und Betriebsweise des MegaVideo 55

Der MegaVideo 55 ist ein programmierbarer Stereo-Modulator, der Audio- und Videosignale, z. B. Ihres DVD-Spielers, Satellitenempfängers, Videorecorders, Ihrer Überwachungskamera, Ihres Decoders oder PCs umsetzt, und als zusätzlichen Sender an Ihr Antennenkabel zufügt. Anschließend können Sie sich dieses Signal überall dort im Haus, wo Sie über einen Antennenanschluss verfügen, als eine Art internen Fernsehkanal betrachten.

Der Modulator wird sozusagen in das Antennensignal ‘eingefädelt’. Das eingehende Antennensignal wird an den Antenneneingang angeschlossen. Das ausgehende Antennensignal ist mit einem zugefügten Audio- und Videosignal (beispielsweise eines DVDSpielers) ausgestattet. Auf allen Fernsehgeräten, die an die dem Modulator nachgeschaltete Antennenanlage angeschlossen sind (an der Seite von ‘RF ANT OUT’ Ihres MegaVideo 55), kann das zugefügte Audio- und Videosignal auf dem eingestellten Kanal betrachtet werden. Am verbleibenden Antennennetzwerk brauchen Sie keine Änderungen vorzunehmen.

Dank des sog. eingebauten “Infrarot-Hilfskanals” können Sie die angeschlossenen Geräte auch weiterhin von anderen Räumen aus mit Ihrer eigenen Fernbedienung bedienen.
