Radio Shack 15-2506 User manual

1-4 Bi-Directional
Cable-TV Amplifier
15-2506
Selecting a Location
Your amplifier should be placed close to your
input source and an AC outlet. You can mount the
amplifier on a wall or other surface using #6
screws (not supplied) suitable for mounting in
your location.
• Do not place the amplifier outdoors.
• To keep exposed cable to a minimum, you can
place the amplifier in your attic.
• To prevent interference, do not place the
amplifier within six inches of any other
electronic device.
Routing Cables
Route 75-ohm (RG-6 or RG-6QS) coaxial cable from the amplifier to your
input source and to each receiver. Follow these hints when routing cable:
• Use only as much cable as necessary to reach from the amplifier to the
input source and receivers.
• Do not route cables where they might be cut, crimped, or crushed by
normal activities.
• For the best appearance, route cable through the attic and walls, and
terminate each cable in a wall mount box with an F-connector. Wall
mount F-connectors, coaxial cable, and other video accessories are
available at your local RadioShack store.
Step One Step Two
Making Connections
1. Connect a coaxial cable to your input source. To
connect more than one input source, use a high
isolation A/B switch or video selector to switch
between inputs.
2. Connect the coaxial cable from your cable box or
antenna (input source) to the amplifier’s INPUT
terminal.
3. Connect one end of the coaxial cable to an
output device and the other end to an OUTPUT
terminal.
4. Attach supplied terminators to unused output
terminals.
5. Connect the supplied AC adapter to the jack on
the amplifier.
6. Plug the AC adapter into a standard AC outlet.

7. Turn on every device connected to the amplifier.
8. Use a flat-head screwdriver to adjust
GAIN MIN/MAX until you get the best picture.

Introduction
The RadioShack 1-4 Bi-Directional Cable-TV
Amplifier is ideal for distributing a cable signal to
a remote location. It can also distribute antenna
and HDTV signals. This amplifier increases the
output signal up to 8dB, while minimizing
interference. It also allows bi-directional
communication so you can enjoy pay-per-view
events and interactive TV. It is also compatible
with digital cable modems. The amplifier can be
mounted on a wall or placed on a table or other
indoor surface. You can cap off the unused
outputs with the supplied terminators to reduce
signal leakage.

power is on.
INPUT — Connect
a coaxial cable
here to connect to
your cable system
or antenna.
OUTPUT 1, 2, 3, 4 — Connect coaxial
cables here to connect to up to four
devices, such as a TV, cable modem, or
HDTV.
GAIN MIN/MAX —
Adjust for the best
TV picture quality.

Limited 90-Day Warranty
•Read and retain all the safety and operating instructions.
• This appliance should not be used near water, such as near a
bathtub, washbowl, kitchen sink or laundry tub.
• This amplifier should be situated so that its location or
position does not interfere with its proper ventilation.
• This amplifier should be connected only to a power supply of
the type described in the operating instructions or as marked
on the amplifier.
• Do not attempt to defeat the grounding or polarization
components of this amplifier.
• Wipe the amplifier with a damp cloth occasionally to keep it
looking new. Do not use harsh chemicals, cleaning solvents,
or strong detergents to clean the amplifier.
• The power cord of the amplifier should be unplugged from
the outlet when left unused for extended periods of time.
• Do not allow liquids to spill through the amplifier’s openings.
• The amplifier should be situated away from heat sources
such as radiators, heat registers, stoves or other appliances
that cause heat. Temperature extremes can shorten the life
of electronic devices and distort or melt plastic parts.
• If an outside antenna is connected to a receiver, be sure the
antenna system is grounded to provide some protection
against voltage surges, built-up static charges, and lightning
strikes. Section 810 of the National Electric Code (NEC),
ANSI/NFPA NO. 70-1990, provides information with respect
to proper grounding of the mast and supporting structure,
grounding of the lead-in wire to an antenna discharge unit,
size of grounding conductors, location of antenna-discharge
unit, connection to grounding electrodes, and requirements
for the grounding electrode.
• The CATV system installers attention should be directed to
Article 820-40 of the NEC that provides guidelines for proper
grounding and, in particular, specifies that the cable ground
shall be connected to the grounding system of the building,
as close to the point of cable entry as practical.

Specifications are typical; Individual units might vary. Specifications are subject to change and improvement without notice.
• Do not use pliers to tighten screw-on F-connectors.
• Never connect both an outdoor antenna and the output from
the amplifier to the antenna input of your TV or VCR without
using a high isolation A/B switch. Doing so could cause
interference with other nearby receivers.
• For an additional grounding method, remove a rubber foot
from the amplifier and back out the #6 grounding screw. Place
a grounding wire over the grounding screw and tighten the
screw back into the housing.
• In extremely long cable runs (distances over 200 feet),
additional amplification might be needed.

Cautions:
You must use a Class 2 power source that supplies 12V DC and delivers at least
100 mA. Its center tip must be set to positive and its plug must fit the amplifier's
adapter jack. The supplied adapter meets these specifications. Using an adapter
that does not meet these specifications could
damage the amplifier or the adapter.
Always connect the AC adapter to the amplifier before you connect it to AC power. When you finish,
disconnect the adapter from AC power before you disconnect it from the amplifier.
