Connecting to a TV using an RF Modulator
Connection 1
Figure 1 Connecting the TV to the unit through the
VCR
Note: All VCRs will distort the picture of a Home
Theater System . This is NOT a malfunction of the
Home Theater System or VCR. All DVD manufac-
turers are required to install macrovision copyright
circuitry to prevent copying via VCR. This is what
causes the distortion.
1) Connect the three-terminal composite video
cable to the back of your Apex Home Theater
System . This cable has three prongs, one each in
yellow, red, and white. The yellow prong will go into
the jack labeled “Video Out”; the white prong will go
into the jack labeled “AUDIO L OUT”; the red prong
will go into the jack labeled “AUDIO R OUT”.
2) Connect the opposite end of the composite video
cable into the back of the RF modulator. Make sure
to match up the colors correctly.
3) Connect a coaxial cable from the “Antenna Out”
jack on the back of your VCR to the “Antenna” jack
on the RF modulator. The coaxial cable is the one-
wire, metal-ended type that you screw onto the
VCR.
4) Connect a coaxial cable from the “To TV” jack on
the RF modulator to the jack on the back of your
TV.
Many older televisions do not have the newer Component-Video, Composite-Video, or S-Video connections that
optimize DVD technology. While it would be advised to purchase a newer television in order to take full advantage of
the digital quality of DVD’s, it is possible to connect an older television to a Home Theater System . This connection
requires a device called an RF modulator.
First, it is necessary to ascertain whether or not your TV needs an RF Modulator. Look at the back of your TV. If
you see three input connectors lined up in a row, in the colors of yellow, red, and white, then you will not need an
RF modulator. If you see the connectors labeled “S-Video” or “Component Video”, then you will not need an RF
Modulator. If you do not have either of these connectors, then you will need to purchase an RF Modulator from the
store where you purchased your Apex Digital Home Theater System or other home electronics retailers.
Older televisions use a coaxial connection, which combines all of the video signal from an exterior source into a
single line. This line is then translated by your TV into the picture you see. The RF modulator combines the output
signals from the Home Theater System , or any other device, into the coaxial connection for use by your television.
Below are written and pictorial instructions on the proper way to connect an RF modulator to your Apex Home
Theater System and your TV.
5) Make sure your TV is set to the appropriate chan-
nel before using your Home Theater System . In most
cases, this is channel 3 or 4.
