Introduction
Thank you for purchasing the Samson AirLine Micro Earset wireless system, a breakthrough in wireless microphone technology.
Wireless systems were originally developed to eliminate cables. Samson took this one step further by creating the AH2 single earset
transmitter, which provides unparalleled freedom of movement. The AirLine Micro features an integrated omni-directional micro-
phone and flexible gooseneck boom, which always allows you to obtain the perfect position to pick up your voice, even during
high-impact performance. The frequency response of the transmitter has been tailored for accurate and articulate vocal reproduc-
tion. The AH2 transmitter is also water resistant, and designed with extra care to ensure that no moisture can accumulate during
performances. This makes the AH2 perfectly suited for aerobics instructors, and high-energy performers and presenters.
Housed in a rugged aluminum chassis with retractable antennas, the AR2 provides the ultimate in portability and flexibility. The
AR2 micro receiver features an 1/8” unbalanced audio output, with microphone or line level output, USB DC-input, and RF and
Battery LED indicators. The included AR2D dock provides stability for the receiver, and facilitates ease of use.
The AirLine Micro utilizes the latest in miniaturized electronic components, as well as lithium ion batteries, which result in Samson’s
smallest and most comfortable wireless system, while preserving the high-quality audio you expect out of a Samson wireless
device. The AirLine Micro system ensures clear, interruption-free performance by incorporating tone-key with auto-mute, which
only allows the transmitter’s audio to pass through the receiver, and mutes the output if there is interference.
The AirLine Micro system uses fully rechargeable Lithium Ion technology. The AirLine Micro AH2 transmitter and AR2 receiver fea-
ture internal rechargeable batteries for 10 hours of battery operation. Both the AH2 and AR2 can be recharged with the included
AC adaptor and USB Y-cable. The AR2 can be powered directly off of the AC adaptor, for continuous operation. The AH2 and AR2
can also be recharged by USB bus power when connected to any USB host-equipped device.

Introduction
In this manual, you’ll find a detailed description of the features of your AirLine Micro Earset system, as well as a guided tour of its
components, step-by-step instructions for setting up and using your system, and full specifications. If your AirLine Micro Earset
system was purchased in the United States, you’ll also find a warranty card enclosed—don’t forget to fill it out and mail it! This will
enable you to receive online technical support and will allow us to send you updated information about this and other Samson
products in the future. If your Airline Micro Earset system was purchased outside of the U.S., contact your local distributor for war-
ranty details. Also, be sure to check out our website (http://www.samsontech.com) for information about our full product line.
SPECIAL NOTE for U.S. Purchasers: Should your Airline Micro Earset system ever require servicing, a Return Authorization (RA)num-
ber is necessary. Without this number, the unit will not be accepted for return. If your AirLine Micro Earset system was purchased in
the United States, please call Samson at 1-800-372-6766 for an RA number prior to shipping your system. If possible, return the unit
in its original carton and packing materials. If your AirLine Micro Earset system was purchased outside of the U.S., contact your local
distributor for information.
BATTERY NOTE: Lithium-ion batteries are low maintenance and provide higher power in a lighter package when compared to
NiCad (nickel-cadmium). All Lithium-ion batteries have a finite number of times they can be recharged, called a charge cycle. A
charge cycle means using all of the battery’s power, but does not necessarily mean a single charge. The battery can be recharged
when needed, and does not need to be fully discharged (as compared to NiCad). Repetitive full discharges of the battery should be
avoided. Lithium-ion batteries need to be used for maximum life and performance. If you are not using your wireless system often,
be sure to complete a full charge cycle at least every three months. If you need to replace your AH2 or AR2 battery please contact
Samson or your local distributor.

Quick Start
Please follow these basic procedures for setting up and using your AirLine Micro:
1. For your AirLine Micro system to work correctly, both the receiver and transmitter must be set to the same channel. Remove
all packing materials (save them in case your unit needs service in the future) and check to make sure that the supplied
receiver and transmitter are set to the same channel.
Note: The channel number is laser-engraved on the back of the AR2 and AH2 chassis. If these channels do not match, please
contact Samson Technical Support at 1-800-372-6766. If your unit was purchased outside of the U.S., please contact your local
distributor.
2. Before using your AirLine Micro system you should fully recharge the transmitter and receiver batteries. Plug the AC adap-
tor into a power socket. Connect the USB Y-Cable into the USB socket on the AC adaptor. Plug the two mini-USB connectors
into the USB ports on the AH2 transmitter and AR2 receiver. When the transmitter and receiver are completely charged, the
BLUE LED indicator will turn off.
3. Remove the USB cable and continue with setup.
4. Physically place the receiver where it will be used (if desired, the AR2 receiver model can be used with the included AR2D
dock) and fully extend the antennas vertically.
5. Turn your audio system off and connect the receiver’s 1/8” unbalanced output jack to the microphone or line level audio
input of your amplifier or mixer. Set the AR2 Mic/Line Level switch to match the input.
6. Turn on the receiver using the Power Switch. When on, the Status Indicator will be steady YELLOW.
+4+0'+%41#45'690'45#07#. I
7. Turn on your AH2 transmitter by pressing and holding the Multi-Function Switch, until the Status Indicator LED flashes
GREEN, then release it. The AH2 Status Indicator will now light steady GREEN. The AR2 receiver Status Indicator will change
from YELLOW to GREEN indicating that it is receiving a valid RF signal.
8. Position the AH2 on your head, as illustrated on page 7.
9. Turn on your connected amplier and/or mixer, but keep its volume all the way down. Make sure the AH2 transmitter is not
muted.
Note: If the AH2 is muted, the AH2 Status Indicator LED will ash GREEN and the AR2 Status Indicator will ash GREEN. To unmute
the AH2, press the Multi-Function Switch and the Status Indicator will light steady GREEN.
10. Speak or sing into the earset microphone at a normal performance level while slowly raising the audio input control of your
amplier or mixer, until the desired volume is reached.
11. If you hear distortion at the desired volume level, check to see whether the Status Indicator LED on the receiver is lighting
RED. If it is not lit, make sure that the gain structure of your audio system is set correctly (consult the owners manual of your
mixer and/or amplier for details). If the Status Indicator is RED, simply move the microphone further from your mouth.
If you hear a weak, noisy signal at the desired volume level, make sure that the gain structure of your audio system and the
Audio Output Level switch are correctly set. If the Audio Output Level switch is correctly set and the signal coming from the
receiver is still weak and/or noisy, simply position the microphone closer to your mouth.
Quick Start
+4+0'+%41#45'6 90'45#07#.J
If you feel that the level of the microphone needs further adjustment, press and hold the AH2 Multi-Function Switch while
the unit is powered on until the Status Indicator turns o, and release the switch. Then press and hold the Multi-Function
Switch again for 5 seconds. The AH2 Status Indicator will rst ash GREEN then ash YELLOW to show that you are in the
Volume Adjustment mode. Press and release the Multi-Function Switch once, and the microphone volume will increase one
level. To continue to adjust the microphone volume, press and release the Multi-Function Switch until the maximum level
is reached. There are 5 levels. With each increasing level, the Status Indicator will ash faster. After level 5 is reached, the
transmitter will cycle back down through the levels each time the Multi-Function Switch is pressed. As the levels decrease,
the Status Indicator ashes slower. When the desired level is reached, release the Multi-Function Switch. The AH2 will return
to normal operation after 10 seconds, and the Status Indicator will be steady GREEN.
12. Do a walk-around through the intended area of coverage while observing the AR2’s Status Indicator; it should stay steadily
GREEN, indicating sucient RF reception in all areas of coverage. If the AR2’s Status Indicator lights YELLOW, it designates
RF dropout or muted receiver. Reposition the device (or its antennas) as necessary. If extended range coverage is required,
another AR2 true diversity receiver (set to the same channel as the transmitter) should be used.
13. If you have followed all the steps above and are experiencing diculties, please call Samson Technical Support
(1-800-372-6766) between 9 AM and 5 PM EST. If you purchased your system outside of the U.S., please contact your local
distributor.
