3 Introduction

Thank you for purchasing the MyM Micro Master, a quality product developed and

manufactured by A2B Electronics.

The MyM is a unique solution that allows you to watch digital television on all your

TV sets. The MyM receives all terrestrial digital programs, and re-transmits 3

programs simultaneously to all your TV’s.

This User Manual describes how to install and connect your MyM quickly and easily .

In the unlikely event that you experience any difficulties please refer to Chapter

10, Support and Trouble Shooting.

4 Information about digital terrestrial television

Today there are digital terrestrial channels available, both free to air and

encrypted channels.

The terrestrial digital channels are transmitted in muxes. A mux (or multiplex) is a

package of channels that are transmitted on the same frequency. Each mux

normally contains between 4 and 7 channels. Frequently a mux will contain both

free to air and pay TV channels.

The MyM receives transmissions from 2 muxes, and re-transmits 3 of the digital

channels in analogue with Nicam or A2 stereo to all connected receivers (TV’s,

VCR’s etc.) in the cable TV network. There is also a loop through of the digital

muxes, which makes it possible to connect a Set Top Box (STB) after the MyM.

5Installation Part one

The MyM should be mounted correctly to ensure excellent performance over a long

period of time.

Please note that it is important to mount the MyM vertically for correct airflow.

Attach the MyM to a suitable surface using the holes on the back side. There is also

a wall mount plate that can be used together with a padlock for protection of the

CA modules.

Install the MyM for easiest connection of the cables. If the MyM is installed in the

attic, mount it close to the aerial. Also, make sure you have a 230V AC power

outlet. For more information about how to install the MyM please refer to Chapter

7 Installation.

7Installation Part two

7.1 Connect ion t o one T V

If you only want to connect one TV, or one TV combined with a VCR / PVR, the

most straight-forward installation is to mount the MyM on the wall close to the TV.

1. Connect the aerial cable to the aerial

input on the MyM

2Connect the one end of a RF cable to

the RF output on the MyM, and connect

the other end to the aerial in socket on

your TV.

3Connect the power adaptor (only use

the adaptor delivered with the MyM).

4The MyM will now start an automatic

channel search. When the channel

search is finished the LED on the MyM

will turn red or green ( depending on if

the selected services are encoded or

not). You now have to do a channel search on your TV to get the 3 channels

from the MyM. See Chapter 7.3 Automatic installation and channel search,

for more information.

Not e! Do not use any ot her t he power adapt or t han t he or iginal one wit h t he MyM.

7. 2 Connect ion t o a Cable net work

The MyM should be connected close to the aerial, before the signals are split to the

cable network.

If there is an amplifier connected to the

splitter you should first try to install

the MyM without the amplifier, because

the MyM has an embedded amplifier.

If there are long cables in the cable

network, an amplifier can be needed

and should then be connected after the

MyM.

7. 3 Aut omat ic inst allat ion and channel search

The MyM will automatically start a channel search when it is connected to a TV

aerial and the power adaptor is connected. The MyM will search for the strongest

transmissions, and after that it will start transmitting three channels according to

the table below:

Channel Frequency

S11 231,25 MHz

S13 245,25 MHz

S15 259,25 MHz

The channel search takes about 60 seconds. When the channel search is complete,

the LED on the MyM will turn to red or green depending on if found channels are

FTA or encrypted services.

NOT E! In normal operat ion t he LED f lashes green.

7. 4 TV channel search

Once the channel search on the MyM is complete you will

need to do a channel search on all TV’s and VCR’s in the

cable network. Many TV sets have an automatic channel

search facility - for more information please refer to the

TV and VCR User Manuals. Channels coming from the MyM

will be highlighted by a text box with “MyM 1”, “MyM 2”

and “MyM 3” in the upper right corner. This text box will

disappear automatically after 8 hours. You can also

remove the text box manually via the menu system of the

MyM, see Chapter 8 Menu settings, for more information.

If you need help to install your MyM, please contact your local dealer/installer. You

can also visit our web site for more information: www.a2b.se
