206-3360-O
Locate the Antenna/Cable 2 jack on
the back of your TV. Connect the
cable that runs from the wall direct-
ly to the jack. Now find the the
Loop Out jack.
Connect the cable from this jack to
the Input jack on the back of your
cable box.
Locate the Output jack on the back
of your cable box. Connect this to
the Antenna/Cable 1 jack on the
back of your TV.
To view the premium stations, set
the channel number on your cable
box to HBO®, CINEMAX®, SHOW-
TIME®, etc. Then go to the Source
menu and select the Antenna/Cable
1 source. See your Quick Setup
Sheet, included with this operating
guide for more information. See
page 20 for information regarding
Source Menus.
To view the non premium channels
go to the Source Menu and select
Antenna/Cable 2. Then run Channel
Search to check for all available
channels and store them in its
memory.
This can be combined with any
other equipment you may want
to hook up. Hook cable directly into
the TV, then to the cable box. From
there, the cable box goes to the
next device, down the line, until
the last piece, which connects back
to the TV in the Antenna/Cable 1
jack.

Some cable services require the use of a
cable box to decode premium channels and
pay-per-view. Using the Loop Out to
Decoder option, and programming your
remote, you can connect your cable box so
that you only need your MBR Trakball
remote to control all the channels. By
connecting cable directly to your
Entertainment Machine, then running it out
to the cable box and back, you make the
cable box another source to choose from in
the Source menu (see page 20).

This is just a general room design.
Any number of set-ups are possible,
and some changes may be needed
to maximize your sound.
A left and right speaker on either
side of the Entertainment Machine
will create a phantom “center
channel,” making the dialog sound
as though it’s coming directly from
the Entertainment Machine. The rear
surround sound speakers provide
the majority of other sounds, like
those from special effects in movies.
Your sub-woofer generates ultra-low
frequency sound, for rumbling
low-end audio.
Sound is affected by
speaker placement, so
make sure nothing is in
front of the speakers, and
that they are aimed in
appropriate directions.
You have the option of
turning on or off the internal
speakers.
If your surround sound
system is on, but there’s no
sound from the speakers,
the program you’re watching
might not be broadcast in
surround sound.

Locate the Surround Speakers jacks on the

the wires to the right or left channel, depend-
ing on where the speaker is located in your
room. The copper wire corresponds to
the Negative jack, and the silver to the
Positive.
Locate the jacks marked Variable Out. These
are for the sub-woofer. Connect the sub-
woofer’s cables, according to their color (red
is the right channel, white the left) to these
jacks.

If you happen to have Mini-tower
speakers, these will be connected
to the back of your sub-woofer,
with the jack labeled Satellite
Speaker Output.
Before you begin plugging in your speakers,
it’s a good idea to put them in their
approximate places first. That way you
know how much wire you have or will need.
Locate the Variable Out jacks on
the back of your Entertainment
Machine and the Input jacks on
the back of your stereo’s amplifi-
er.
Connect the two jacks, making
sure that the right and left
channels are placed correctly.
Set up your speakers through
your stereo, according to
those directions.
