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.

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.
