Guided Tour - AL1 Presentation Transmitter
Samson AirLine
1: Power / Battery LED - This LED flashes once when the AL1 is first turned on and lights
steadily red when there is less than 2 hours of battery power remaining, indicating that the bat-
tery needs to be changed.
2: Antenna - This permanently attached flexible antenna should be fully extended during nor-
mal operations. See the "Setting Up and Using Your AirLine System" section on page 17 in this
manual for more information about antenna positioning.
3: Electret condenser microphone - This high- quality unidirectional electret condenser
microphone with metal windscreen is optimized for clear, crisp reproduction of speech. It is
active whenever the AL1 is powered on, as long as there is no connection made to the lavalier
microphone input connector (see #4 below). When a plug is inserted into the lavalier micro-
phone input connector, this built-in microphone is muted.
4: Lavalier microphone input connector - Use this
standard 2.5 mm mini-jack if you want to connect an
external lavalier microphone to the AL1. Note that,
because the AL1 has a built-in electret condenser
microphone (see #3 above), the use of an external
lavalier mic is optional and not required. The AL1 pro-
vides 2.7V of phantom power, so condenser mics can
be used if desired.
