FIRST TIME INSTALLATION
Select one of these alternatives when you have a single antenna
equipped with 2 LNBs, or two antennas with one LNB on each,
and want to watch channels from ASTRA/HOTBIRD or THOR/
SIRIUS.
In this case you must first connect the LNBs to an external switch
since there is only one antenna input on the Mediamaster. Once
installed the switch automatically selects the correct LNB for the
selected channel.
This external switch is better known as a
DiSEqC ™
switch. Since
the switch can be located
close to the LNBs
, you only need
one
cable down to the Mediamaster.
• First check, as described in paragraph
Antenna adjustment
and signal check
on page 14, that you get picture and sound
from ASTRA (THOR).
• When you have picture and sound continue to the next row
and check HOTBIRD (SIRIUS) for picture and sound.
• When the HOTBIRD(SIRIUS) check is ready, press
OK
to start
the channel search procedure. The box now starts searching
and downloading channels from both satellites. See “Channel
search” on page 18.

DiSEqC switch with 2 inputs
Connection of a DiSEqC switch:
• Connect the cable from the LNB intended for channels from
ASTRA (or THOR) to the connector marked LNB 1 or A on the
switch.
• Connect the cable from HOTBIRD (or SIRIUS) to the connec-
tor marked LNB 2 or B.
• Then, connect the antenna cable to the connector marked OUT
on the switch.
• Connect the other end of this cable to the ANTENNA input in
the rear of the Mediamaster.
On the
most common type of DiSEqC switches
the connec-
tions are usually marked
1
and
2
.
On the
mini DiSEqC switches
the connections are usually
marked
A
and
B
.
As a principle they perform the same work, but demands differ-
ent electric commands from the receiver in order to start work-
ing.
