DESCRIPTION CONT

DESCRIPTION CONT

REAR PANEL

AC: Three connector iec power cord. Please connect to a properly grounded AC outlet.

Power Select Switch: Selects between 115 Volt (US), and 230 (Europe) AC power voltages. This switch MUST be in the proper setting before the RS80 is turned on.

Right and Left Outputs: Balanced XLR and unbalanced RCA outputs.

FM ANT. 75 Ohm: Connects to the included 75 ohm FM antenna.

AM LOOP ANT. 300 Ohm: Connects to the included 300 ohm AM Loop an- tenna.

CONNECTION

Connect the RS80 to a properly grounded AC outlet.

Connect the Left and Right outputs to a mixer, amplifier, or other audio device.

FM Antenna Indoor FM antenna

Connect the wire FM antenna to its corresponding input on the rear panel of the RS80. While listening to a broadcast, hold the wire end 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 suppress- es 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 Ohm terminals. When tuning in AM stations, move the antenna to the left or right and set in the direction which yields the optimum reception.

Do not bring the power cord or speaker cords near the loop antenna. Interfer- ence or noise may 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 loca- tion with strong reception.

OPERATION

SET THE FREQUENCY SELECT

To change the AM tuning steps from 9kHz to 10kHz (and vice-versa), press and hold down the PTY SEARCH button for three seconds.

AUTO SEARCH

Press the AUTO SEARCH button to scan for all available stations. The stations will be stored in the 40 available Presets.

PROGRAMMING PRESETS

Press the PRESET+ / PRESET-, SEEK +/SEEK-, or TUNE+/TUNE- buttons to access specific stations you want stored. When the desired station is located, press the STORAGE button - then press the PRESET + or PRESET - button to select the desired storage location. When that location is reached, press the STORAGE button to store the preset.

RDS (Radio Display System) FUNCTION

RDS is a data stream of information sent out by certain FM radio stations along with the actual program. To utilize this feature, you must first be tuned to a station that carries this RDS signal; the display will indicate "RDS". NOTE: Allow 30 - 60 seconds for the data to download. Not all stations that carry the RDS data - carry all functions of RDS (ie; some do not carry the "clock" or "text" data).

To search for and store stations with a certain Program Type (PTY) (such as Rock, Country, News, etc.), press the RDS/PTY button repeatedly until you see the Program Type you want. When you see the Type you are looking for, press the PTY Search button. This will search for all the RDS stations that carry that kind of programming - when it reaches one, it will stop on that station and exit PTY Search mode.

PLEASE NOTE: THE PTY SEARCH FUNCTION IS ENTIRELY DEPENDENT ON WHETHER THE STATION FIRST PROVIDES THE PTY INFO, AND SEC- OND IF THE STATION'S PTY INFO MATCHES YOUR EXPECTED TYPE.

THEREFORE - THE RESULTS OF THE PTY SEARCH VARIES GREATLY.

To see the RDS information carried on a certain station, press the RDS Display button repeatedly. This will scroll through the available RDS info on that station. 4
