4. EXTERNAL AM ANTENNA
In ferroconcrete buildings or in areas remote from broadcast stations, the built-in antenna may not prove
adequate. To supplement the built-in antenna, connect 10 to 20 feet of insulated, flexible, single conductor
wire to this terminal, but this wire should be kept away from all speaker cables and power cables and run in
a straight line along a nonmetalic baseboard or under a rug.
5. SYSTEM GROUND TERMINAL
To reduce hum to a minimum, this terminal is used to interconnect the chassis or ground lead of the
Turntable to this Receiver. Connect the ground lead from your Turntable to this terminal.
