RF LED
Lights when the transmitter is turned on and the receiver has a good signal. When the carrier signal
from the transmitter is too weak to produce a clean audio signal, the lamp will go out.
MINI PHONE JACK
Provides a monitor, separate from the rear panel XLR audio output. The output level from this jack is
controlled by both the OUTPUT control and the recessed trim-pot on the side panel. Generally, the
OUTPUT control would be set to provide the proper output level at the rear panel XLR jack, and then
the side panel trim-pot adjusted to match the required level for your earphone.
The output at this mini connector is designed for a medium impedance earphone. An earphone with an
impedance between 30 and 300 Ohms will usually provide adequate volume. The sound from a low
impedance ear phone (ie. 8 Ohms) will not be very loud and may be distorted at higher listening levels.
ANTENNA JACK
Connects to any 50 ohm antenna with a BNC type connector (a flexible "rubber duckie" antenna is
supplied). The A-185 Coax remote type antenna may also be used.
