Introduction
The Nexxtech 4-Way Professional Broadband Signal Amplifier
TM
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 8 dB, 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 terminators (not
included) to reduce signal leakage.
Step One: 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 included) 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
15 cm of any other electronic device.
Step Two: 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

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.

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
using the supplied 15 cm RG-6 cable.
6. Plug the AC adapter into a standard AC outlet. The amplifier's

7. Turn on every device connected to the amplifier.
Notes
• 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 60 m), additional
amplification might be needed.

Safety Instructions
• 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
• The CATV system installers attention should be given to
proper grounding and, in particular, that the cable ground shall
be connected to the grounding system of the building, as
close to the point of cable entry as practical.
