The CENTER channel speaker can be above or below the video monitor, depending on your installation.
If
a video
projector and an
acoustically transparent
screen are used, the center channel speaker can be
behind
the screen.
SURROUND (REAR) speakers should be placed to the sides of the listener,
not behind.
They should be elevated
above ear level if possible.
The SUBWOOFER(S) will require some experimentation for the best placement. A comer may be the easiest
location for installation but a corner may not provide the best sound integration with the other speakers. One
advantage of corner placement is reinforcement of the low frequencies by being in proximity to the walls and floor.
Comer placement will boost the apparent sensitivity of the subwoofer by as much as 6 dB, which will save
amplifier power. It may also b<4ost mid bass output, however, which could be undesirable. (Read the owners
manual included with your subwoofer for further information.)
CUSTOMER SUBWOOFER TUNING NOTE: An easy way to "tune" for extended low frequency bass
response is to
place the
SUBWOOFER
in your favorite listening spot
and move around the room listening for
the "room modes" in the low frequencies. Some parts of a room will accentuate bass response and some will
diminish it, depending on the shape and size of your room. Low bass will be affected the most but all frequencies
are affected to some extent. You should crawl around on the floor at speaker level to find the location that
gives the smoothest low frequency response.
(Sorry, but this does work!)
A test CD with
warble
tones from 20-40 Hz is ideal as a source for this test. Sine wave test tones can also be used
but will be subject to "standing waves" or pressure and null zones. Play test tones at a moderate level only, not at
a loud level. If played at a high volume level with a subwoofer, you may find that your walls rattle and your
neighbors ring the doorbell to complain. Neither is an especially desirable result.
When you have placed the subwoofer(s) in a promising location, play some music with strong bass
content and listen for extended low frequency bass response and definition. Minor placement adjustments
may be needed to find the optimum location. The result of proper placement of the subwoofer will be excellent low
bass as well as mid bass. It should smoothly "blend in" with the main speakers for good sound quality.
With proper placement, combined with well-placed front and surround sound speakers, you can achieve a
thoroughly convincing sound field in your listening room. Multiple subwoofers are potentially capable of smoothing
the low frequency response in a room a little more due to interaction with the room modes from more than one
location. Proper set up of your speakers will take some time. This is time and energy very well spent. When
you are enjoying music or movies with your family and friends, you will be glad you invested the time in
proper set up and location of your speakers and system.
CABLES FOR A SURROUND SOUND SYSTEM
High performance COMPOSITE VIDEO and AUDIO patch cables will improve the sights and sounds of your
system and we recommend them. Composite video or digital cables should have a characteristic impedance of 75
ohms and should be well shielded for the best video or digital performance. Audio/video and AC power cables
should be kept separate from each other to avoid potential interference or hum that will degrade sound or picture
quality. Ask your ROTEL/j/
fi
AUTHORIZED DEALER for advice about high quality cables for analog, video and
digital signals in your sound system.
They do make a difference
and high quality cable will yield the best results.
ELECTRICAL REQUIREMENTS
The RSP 970 is designed to work on AC voltage and the correct voltage is displayed on the back panel. Do not
attempt to operate on incorrect voltage as this will damage the circuitry and void your warranty. If you are
in doubt about the correct voltage we suggest that you read the label on the back panel or consult your ROTEL
hi fi
AUTHORIZED DEALER for confirmation of the correct voltage. Connect the Power Cord to your wall socket for
AC power. When you wish to disconnect the power cord from the wall, always hold the plug firmly and pull the plug
out of the wall socket. Do not unplug the power cord from the wall by pulling the cord only. This may
damage the power cord and create a hazardous condition. We recommend connection to the mains' wall
socket or an AC power line filter, not to an extension cord. There are two
switched
AC outlets on the back panel.
Please do not exceed the power rating (800 watts total) printed next to the outlets. The switched AC outlets are
provided for a source component or the CONTROL CORD of the Rotel RLC 900,
not a power amplifier.
There is
NO
user serviceable part inside the RSP 970. Please do not open the cabinet as this will expose you
to the risk of potentially dangerous high voltage and the risk of shock. This could also damage the circuits
and possibly void your warranty.
