Setting Up and Using Your AirLine System
Samson AirLine
video camera), then plug the adapter into any standard AC outlet. Slide the Power switch in the direction of the arrow to turn on the
receiver. If your system contains an AR1 receiver, its "Power/ RF" LED will light steadily red; if your system contains a UR1 receiver,
its "Power" LED will light steadily red. (Note: The UM1 receiver has no "Power" LED indicator.)
8. Turn on the power to your AH1 transmitter (using its Power on-off switch); the "Power/Battery" LED will flash if the battery is
suf-
ficiently strong (if it lights steadily, the battery has less than 2 hours of power remaining and should be replaced). If your system con-
tains an AR1 receiver, its "Power/ RF" LED on the receiver should change color from red to green, indicating that it is receiving valid
RF signal and is placed and positioned correctly. If your system contains either a UR1 or UM1 receiver, one of the "A/B Receiver"
LEDs will light, showing you whether the (left) "A" or (right) "B" receiver is currently being used. The UR1 / UM1 meter will also indi-
cate the strength of the incoming RF signal.
9. Now it's time to set the audio levels. Turn on your connected amplifier and/or mixer but keep its volume all the way down.
Make sure that the AH1 transmitter is unmuted (its Mute switch should be positioned away from the arrrow). Then set the Volume,
Level or AF Level knob on the receiver fully clockwise; this is unity gain.
10. Speak or sing into your headset mic (or play the instrument to which the horn mic is attached) at a normal performance level
while slowly raising the volume of your amplifier and/or mixer until the desired level is reached. The UM1 receiver allows you to
monitor the transmission signal using standard Walkman-type 30 ohm headphones connected to its headphone jack.
11. If you hear distortion at the desired volume level, first check to see whether the "Peak" LED on the receiver is lit . If it is not lit,
make sure that the gain structure of your audio system is correctly set (consult the owners manual of your mixer and/or amplifier for
details). If the "Peak" LED is lit, simply move the microphone further from your mouth.
12. Conversely, if you hear a weak, noisy signal at the desired volume level, again make sure that the gain structure of your audio
system is correctly set (consult the owners manual of your mixer and/or amplifier for details) and that the Volume, Level or AF Level
control of the receiver is fully clockwise. If it is and the signal coming from the receiver is still weak and/or noisy, simply position the
microphone closer to your mouth.
