You may also wish to refer to the owner's manual of your digital recorder. 19 Antenna Connections You will not be able to receive any radio stations unless you connect FM and AM antennas to the AVC-2500. The following are options to connect FM and AM antennas: FM Dipole Antenna A standard FM "folded dipole" 300 wire antenna is included with your AVC-2500. This dipole antenna is adequate for most urban and suburban locations. Connect the spade lugs of the dipole antenna to the two screw terminals on the included small "balun" matching transformer. Press the balun over the female 75 connector of the rear panel of your AVC2500. Next, spread out the antenna and hang it on the wall or the back of the equipment cabinet. Experiment with the direction and placement of the dipole antenna to obtain the best reception. 75 Coaxial Antenna The AVC-2500 has a standard DIN-type 75 connector with a push-on coaxial FM antenna plug. An adapter is included to accommodate the threaded F-type connectors that are used in North America. Outdoor Roof Antenna For best reception and maximum noise rejection, we recommend the use of a high-quality outdoor FM antenna. The additional stations you can receive and the superior sound quality will make the extra effort worthwhile. Connect the outdoor antenna with a 75 coaxial cable directly to the 75 FM Antenna Input of the AVC-2500. If you use 300 twin lead, connect the two bare wire leads to the included "balun" adapter and press it onto the female 75 coaxial FM antenna input connector. Cable TV and Community Antenna In many situations, you may be able to use the FM antenna output of a cable TV or a community antenna jack. These connect in the same way as an outdoor antenna. AM Antenna A molded plastic loop antenna is supplied with your AVC-2500. Connect the two wires of the AM loop antenna to the posts labeled AM and GND. Position the loop antenna for best AM reception. If you are trying to pick up very distant stations, you may connect a single long wire to the AM terminal and a good earth ground to the GND terminal. RS 232 Control The RS-232 External Control port is the interface for connecting one of the many software based system controllers such as AMX, Phast, or Creston. This 9-pin serial port provides two-way communication for control and status feedback from the AVC-2500.
