Introduction
Welcome to Samson AirLine, the original micro-wireless microphone systems. Wireless
microphone and instrument systems were originally developed to eliminate cables, providing
unparalleled freedom of movement. AirLine 99m takes this concept to a new level with
frequency agile transmitters and micro receiver, providing a completely “hassle-free” user
experience.
Featuring miniaturized circuitry and an internal, rechargeable battery the AH9 can operate
for up to 8 hours on a single charge. The AirLine 99m System combines an AH9 headset
transmitter with a Samson Qe Fitness or DE10 low profile headset microphone.
Offering frequency-agile UHF operation, the micro-sized True RF Diversity AR99m receiver
provides 100 available channels to secure reliable wireless performance. The receiver provides
easy setup with 1-touch scan which analyzes and selects the clearest operating channel,
infrared set to pair the transmitter with the receiver, and versatile output connections (XLR,
1/4” and 1/8”). An included USB port can be used to charge the AH9 transmitter or integrate a
Samson XPD Series wireless system (sold separately) to make it a dual-receiver.

As shown in the illustration, the correct way to wear your Qe fitness headset microphone, is
over the ears, as you would wear a pair of eyeglasses. Because the Qe microphone is specially
designed to be used up close, be sure to position the microphone directly in front of your lips.
To avoid feedback problems, take care not to cover the microphone capsule with your hand.
Wearing the AH9 Headset Microphone
Position the headset over your head so
that the body of the transmitter is behind
your head. Adjust the headset so that it fits
comfortably on your ears and is secure against
your head.
Note: If wearing glasses, it is recommended
to put the AH9 transmitter on first than place
glasses over the transmitter.
For added comfort and fit, the headset
includes an adjustable headband. To fit the
headband, pull elastic strap over the ear
hooks and locate in front of the stop point
(A). For larger sizing, the headband can be
moved behind the stop point (B) or completely
removed by sliding the elastic band over the
ear hooks and microphone capsule.
Note: When removing the headband, first take
off the microphone windscreen.

AirLine 99m Wireless System 9
DE10 Headset
Mic Positioning
Fitting the DE10 Headset
Position the DE10 microphone element about
0.25” –1” behind the corner of your mouth.
Since the DE10 is an omnidirectional capsule,
the end of the microphone does not need to
be facing your mouth. To avoid breadth noise
and p-pops, do not place the microphone
directly in front of your mouth.
If the microphone is too far away from your
mouth you will need to increase the gain and
reduce isolation.
To minimize additional noise, do not locate
the microphone tight against your cheek.
The DE10 headset can be sized by sliding the
ear hooks to fit snug around your head. If the
DE10 is loose and will not stay in place, slide
the ear hook wires back for a tighter fit.
Adjust the microphone position by holding
the left ear hook wire and slide the boom
forward or back. For optimum performance
the microphone should be close to the
skin and towards the corner of the mouth,
approximately a half inch away.
Position the moisture guard ring as close to
the capsule as possible.
For outdoor use and to help reduce
p-popping, use the included windscreens.

Quick Start
In order for your wireless system to work correctly, both the receiver and transmitter must be set
to the same channel. Follow this basic procedure for setting up your AirLine 99 wireless system:
1. Physically place the AR99m receiver where it will be used, and extend the antennas
vertically. The general rule of thumb is to maintain “line of sight” between the receiver and
transmitter so that the person using or wearing the transmitter can see the receiver.
2. Ensure that the AH9 transmitter is fully charged (see section Charging the AH9 Transmitter).
3. With the AR99m powered off, connect the included power adapter.
4. With your amplifier or mixer off and volume control all the way down, connect the AR99m
receiver output jack to the mic or line level input of a mixer or amplifier using the balanced
XLR output or unbalanced 1/4” or 1/8” line level outputs. Turn the VOLUME knob on the
AR99m clockwise to turn its power on, but keep the level low.
5. Press and hold the SET button on the front of the AR99m receiver to scan for an available
channel. Once the optimal channel is
selected the receiver will enter IR Set
mode (figure 1).
6. Turn on the power to the AH9 transmitter
by pressing and holding the Power button
for 3 seconds; the indicator LED will light
yellow when the button is pressed and
turns green when released and the AH9
is powered on.
7. Position the AH9 transmitter about
6-12” (15-30 cm) from the front of the
AR99m with the transmitter’s IR window
facing the IR transmitter on the front
panel of the AR99m receiver (figure 2).
8. When the transmission of the operating
channel is complete, the AR99m will
receive RF signal and the READY
indicator will light indicating that it
is receiving wireless signal from the
transmitter.
Note: The AH9 will only accept infrared
transmission from the receiver for
the first 10 seconds after the AH9 is
powered on. If you need to change the
operating channel, the AH9 must be first
powered off, then powered on again to
receive the new channel.
9. Turn on your connected amplifier or
mixer, but keep the volume all the way
down. Set the Volume knob on the
AR99m fully clockwise. This is unity
gain. Speak or sing into the microphone at normal performance level. Slowly raise the
volume of your amplifier or mixer until the desired level is reached.
10. When using multiple systems, each system must be set to a different operating channel.
Follow these steps to set each receiver and transmitter to the optimal channel.

Connecting XPD Wireless
1. Plug the XPD USB receiver into the USB
jack on the side of the AR99m receiver.
2. Place a fresh set of AA (LR6) batteries
in the transmitter battery holder, taking
care to observe the polarity markings.
3. Turn the AR99m receiver on by rotating
the VOLUME control clockwise. The
AR99m VOLUME control will affect the
mix of the AH9 and XPD transmitters.
4. Turn on the power to the XPD transmitter
by pressing and holding Power switch;
the indicator LED will light amber.
5. If the transmitter and receiver have not
been previously paired, press and hold
the button on the XPD receiver for >5
seconds, until it begins to flash. Press
and continue to hold the Power button on
the transmitter until the LED indicators
on both units light steady, indicating that
the receiver and transmitter are paired
and ready for operation.
6. Speak or sing into the microphone at
a normal performance level and raise
the AR99m VOLUME control until the
desired level is reached.
7. To balance the level between the AH9
and XPD transmitter, use the supplied
screwdriver to adjust the Gain control
inside the XPD battery compartment.
If you hear distortion from the XPD
transmitter turn down the Gain.
Conversely, if you hear a weak, noisy
signal at the desired volume level, turn
the Gain control in the XPD transmitter
slowly clockwise until the signal reaches
an acceptable level.

12
Charging the AH9 Transmitter
1. With the AR99m powered off, connect the included power adapter.
2. Insert the magnetic power cable to the AR99m USB Port (or any 5-volt DC adapter that
has a USB port).
3. Turn the VOLUME knob on the AR99m clockwise to turn its power on.
4. Place the AH9 transmitter on a flat surface.
5. Attach the magnetic connector to the gold contact power port on the bottom of the AH9
transmitter. The cable attaches to the port magnetically.
The magnetic connector is keyed so it will only connect in one direction.
Note: Transmission is disabled during charging.
6. Look at the indicator light on the AH9 transmitter to determine when the transmitter has
finished charging. When the light is flashing red, the AH9 is charging. When the red light
stops flashing it indicates that the AH9 is fully charged.
7. Disconnect the magnetic power cable from the AH9 when the unit is fully charged.
If you notice your AH9 battery life is becoming shorter after a full charge, you can order a user
replaceable battery from your local Samson distributer.
Getting the most out of the rechargeable battery:
• Completely charge the batteries before first use
• Fully charge the battery before it will be used.
• After the battery is charged, unplug the charger from the outlet.
• The optimal temperature range for using and storing the battery is 50°F -
86°F (30°C - 50°C). The battery performance and operation may decrease in
temperatures below 50°F (30°C).
A warning that batteries (battery pack or batteries installed) shall not be exposed to excessive
heat such as sunshine, fire or the like.
CAUTION: Danger of explosion if battery is incorrectly replaced. Replace only with the same or
equivalent type. Attention should be drawn to the environmental aspects of battery disposal
