Mains connection 3.1

Power is supplied by a plug-in power supply unit.

The power module is available as a 110, 230 or 240 V AC model. The unit can easily be adapted to changing power requirements by replacing the power module.

Connection of the plug-in power supply unit is via socket P at the back panel of the EM 203.

The two antennas needed for diversity operation (see ch. 1.2) connect to sockets A and B on the EM 302RI module (N-type sockets).

The AB 1036 TV antenna boosters connected in series are powered via sockets A and B. The supply voltage can be switched on or off by means of the switches next to the antenna sockets.

If the antenna boosters are in operation, the control LEDs for the booster supply voltage light up at the front panel (→ ch. 4.2.1).

The AF output signals from every single EM 1046 RX receiver module are available at AF outputs 1 to 3 on the EM 203 module (floating, transformer-balanced). The connection is made through XLR-3 plugs.

The switches at the left-hand side of the XLR outputs ("PAD") allow to attenuate the output signals by 20 dB.
