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
Ω
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
Ω
connector of the rear panel of your AVC-
2500. 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.

Coaxial Antenna
The AVC-2500 has a standard DIN-type 75
Ω
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
Ω
coaxial
cable directly to the 75
Ω
FM Antenna Input of the AVC-2500. If you use 300
Ω
twin lead,
connect the two bare wire leads to the included “balun” adapter and press it onto the female
75
Ω
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. Contact your
Parasound Dealer or Custom Installer for more information regarding interfacing an external
control system to your AVC-2500.
Component Video Connections
Each Component Video Input and the Component Video Output includes three separate jacks.
Separating the video signal components of luminance (Y) and the color difference (Cb and
Cr) delivers the very highest quality video reproduction. Not every source or monitor labels
its component video Y, Cb, Cr. Equivalent labeling for component video connections may
be Y, B-Y R-Y or Y, PB, PR. Refer to the owner’s manual of your video component for
details.
