Samson AirLineSetting Up and Using Your AirLine System
battery has been installed correctly (or that the adapter has been connected correctly); the OOn/Battery Low� LED should light green
and not red. Then turn the AP1 power off.
6. Make the physical cable connection between the AP1 output jack and an audio input of your amplifier or mixer. Leave your ampli-
fier or mixer off at this time.

7. Turn the Level knob on the AP1 completely counterclockwise, then slide its Power switch in the direction of the arrow to turn it on.
The OPower On� LED will light steadily green.
8. Turn on the power to the transmitter. The OTX / Peak� LED on the AP1 receiver should now light steadily green, indicating that it is
receiving valid RF signal and is placed and positioned correctly.
9. Now itOs time to set the audio levels. Turn on your amplifier and/or mixer but keep its volume all the way down. Set the output
level of your electric guitar or bass to maximum and begin playing it at a normal performance level while observing the AP1 OTX/Peak�
LED. If the LED lights red (indicating a Peak condition) even with the AP1 Level control fully counterclockwise, engage the 15 dB pad
on your transmitter by sliding the switch in the direction of the arrow. If not, slowly turn the AP1 Level control clockwise to the point
where the OTX/Peak� LED occasionally blinks red during the very loudest passages, then back it off just slightly; this will ensure maxi-
mum signal to noise ratio. Finally, raise the level of your amplifier and/or mixer until the desired volume is reached.
10. If you hear distortion or the AP1 OTX/Peak� LED lights red even with the 15 dB pad engaged and the Level control at minimum
(fully counterclockwise), reduce the output level of your instrument until the LED no longer lights red. Conversely, if you hear a weak,
noisy signal at the desired volume level, make sure that your instrument is set to maximum output level, that the 15 dB pad is not
engaged, and that the AP1 Level control is turned up. When using instruments with active or high level pickups, the Level control
should normally be set in the marked region.
