OPERATION
SET THE FREQUENCY SELECT
AM radio stations in the United States operate on 10kHz channel centers. In other
parts of the world, stations are on 9kHz centers. The RS79b provides a rear panel
switch to select the frequency centers for proper reception.
If you are not sure where this switch should be set, contact your local station for
their operating information.
PROGRAMMING PRESETS
Select the AM (MW) or FM band you wish to program (AM (MW)1, 2, or FM 1, 2
or 3). Using either the SCAN/UP, SEEK/UP, TUNE +, or TUNE -
buttons - select the station you wish to program. To store that station
in a preset (M1 - M6), press and hold the desired preset button until
the CH # appears in the display. For example, once you've selected
the desired station, to store that in preset M3, press and hold M3 until
a CH 3 appears in the display.
REMOTE OPERATION
The included Infrared Remote provides a way to control the RS79b at
a distance from the unit. It must be located in the "line-of-sight".
The remote functions include all front panel buttons except the A/PS
advance preset button, and the headphone functions.
NOTE:USING THE POWER BUTTON ON THE REMOTE DISABLES
THE FRONT PANEL POWER BUTTON. YOU MUST USE THE
REMOTE POWER TO TURN THE UNIT ON AGAIN.
DESCRIPTION CONT.
REAR PANEL
• AC: Three connector power cord. Please connect to a properly grounded AC
outlet.
• Right and Left Outputs: Balanced XLR and unbalanced RCA outputs.
• FREQ SELECT: This switch selects between 9 and 10Khz frequency
centers for the AM section, and 50 and 100 kHz centers for the FM section.
• FM ANT. 75 W: Connects to the included 75 ohm FM antenna.
• AM LOOP ANT. 300 W: Connects to the included 300 ohm AM Loop an-
tenna.
CONNECTION
Connect the RS79b to a properly grounded AC outlet.
Connect the Left and Right outputs to a mixer, amplifier, or other audio device.
FM Antenna
Indoor T-shaped FM antenna
Connect the T-shaped FM 300 ohm antenna to its corresponding input on the
rear panel of the RS79b. Open the ends of the antenna to form a "T" shape.
While listening to a broadcast, hold the stretched ends and move around until
the antenna is facing a direction where the signal comes in the strongest.
Secure the antenna in this position.
Outdoor FM antenna
Installation of an outdoor FM antenna is recommended for a very high quality
FM reception.
• The lead-in antenna cable should be of the 75-ohm coaxial type as it sup-
presses intrusion of noise more effectively than the 300 ohm twin lead type.
• The cable should be straight and as far away from power lines as possible.
Cut off any extra length.
AM Loop antenna connection
Connect the cord of the accessory AM loop antenna to the AM LOOP 300 W
terminals. When tuning in AM stations, move the antenna to the left or right
and set in the direction which yields the optimum reception.
CONNECTION CONT.
• AM reception may not be possible without the loop antenna attached. Even if an
outdoor antenna is connected, keep this loop antenna in place.
• Do not bring the power cord or speaker cords near the loop antenna. Interfer-
ence or noise will be generated.
Multipath reflections
FM waves, like light waves, travel in a straight direction unless reflected off objects
in their path. Because of this, two sets of waves reach your antenna from the FM
station; those that have traveled directly to the antenna, and those that have been
reflected off buildings or mountains. When the antenna receives both kinds of
signals, the two interfere with each other and result in distorted sound and poor
separation. This phenomenon is called "multipath reflection". To reduce this
problem, select an antenna with good directivity and place it in the best location
with strong reception.
