Installation and
Connections
Observe the following precautions when choosing a
location for your Sherbourn PT-7020A
1. Protect it from prolonged exposure to direct sunlight
and other direct sources of heat, such as heating vents and
radiators.
2. Do not expose the unit to rain or moisture. If fluid or a
foreign object should enter the unit, immediately turn off
the power and contact Sherbourn.
3. Avoid excessive exposure to extreme cold or dust.
4. Do not place heavy objects on top of the unit.
5. If you need to clean the front surface, first turn off the
power and then use a soft dry cloth, rubbing with the grain.
Be careful not to scratch the display window.
AC Power Considerations
Ensure the unit is plugged into an outlet capable of
supplying the correct voltage and current specified for your
model. Remember to account for the electrical power that
other components will require if they share a common wall
socket. The majority of household electrical sockets in
places other than the kitchen and garage are 15 amperes
maximum.
Most DVD players and other source components are fairly
low current items. The Sherbourn PT-7020A requires a
minimum of 2 amperes @ 120 volts.
It should be sufficient to allow the PT-7020A to share a
wall socket with other video source units, but power
amplifiers and a video display (big screen TV or video
projector) should each be provided a SEPARATE electrical
connection on a SEPARATE circuit. This configuration
yields the most stable power supply in any home theater
application, regardless of you equipment choices.
Refer to your power amplifier and video display’s owner’s
manuals to learn the power requirements so you can safely
plan your electrical power requirements for your home
entertainment system.
Connection Tips for
Superior Sound
Before setting up your new system, please consider the
following:
Whenever possible, route the power cord away from the
signal cables or speaker wires to prevent any hum or
interference heard in the speakers.
Use quality coaxial digital cables to connect the PT-7020A
to any source equipment which has coaxial digital outputs.
Optical cables transmit only light pulses and are much more
immune to noises but are sensitive to excessive bends.
Whichever you choose, follow the cable manufacturer’s
recommendations.
Many RCA type patch cords can be a very tight fit and
there is usually a preferred method of getting them off.
Some have to be removed with a twisting action. Be gentle
or you may damage the jacks of your PT-7020A, or other
components.
Many audiophile signal cables are intended to be hooked
up in one direction. If this is the case the cables will be
marked with arrows in the direction of the signal flow.
It is usual for the right channel RCA patch cords plugs to
be red and the left channel connections to be white, grey
or black (depending on the cable brand). RCA connectors
that are gold will be designated with a colored band to
designate the channel.
If the powered subwoofer to which you will connect the
PT-7020A features a balanced XLR input, use the PT-
7020A’s XLR balanced SUB output instead of an RCA
type patch cord if possible. Balanced signal transmission
between the PT-7020A and the subwoofer will provide
superior rejection of hum and noise, especially if long cable
runs are required.
