Introduction
Welcome to Samson AirLine Synth—the next generation of wireless systems! Wireless
microphone and instrument systems were originally developed to eliminate cables,
providing unparalleled freedom of movement. AirLine Synth takes this concept
to a new level with transmitters so small, lightweight and aerodynamic, they are
nearly invisible, providing a completely “hassle-free” user experience. To create the
world’s smallest frequency agile wireless transmitters, we developed new proprietary
technology. Featuring miniaturized circuitry and the ability to operate on a single AA
battery (with 10 hours typical battery life), these transmitters also provide significantly
improved wireless reception and sound quality. What’s more, the AR300 receiver
developed especially for the AirLine Synth guitar system provides over 300 channels
with automatic Channel Scan to help you find the clearest frequency to operate on.
Once the AR300 finds the clearest channel, it’s easy to set the AG300 transmitter to the
matching channel using the IR SET feature. The convenient, all metal half-rack chassis
design features a large backlit LCD display and includes a rackmount kit to install into
a standard 19-inch equipment rack. The Samson AirLine Synth UHF guitar system is
designed to replace the cable between your electric guitar or bass and your onstage
amplifier or PA mixer, freeing you to roam the stage or even visit the audience in the
middle of your performance! It operates in the UHF frequency range and contains an
AR300 “half-rack” receiver and the AG300 plug-in micro-transmitter designed to fit the
recessed style jack in Fender Stratocaster™-type guitars, or convertible, to fit all other
standard end-mount guitar jacks.
In this manual, you’ll find a detailed description of the features of your AirLine Synth
system, as well as a guided tour through all components, step-by-step instructions for
setting up and using your system and full specifications. If your AirLine Synth 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 Synth system was purchased outside of the
U. S., contact your local distributor for warranty details. Also, be sure to check out
our website (http://www.samsontech.com) for complete information about our full
product line.
SPECIAL NOTE for U.S. purchasers: Should your AirLine Synth system ever require
servicing, a Return Authorization number (RA) is necessary. Without this number,
the unit will not be accepted. If your AirLine Synth system was purchased in the
United States, please call Samson at 1-800-372-6766 for a Return Authorization
number prior to shipping your system. If possible, return the unit in its original carton
and packing materials. If your AirLine Synth system was purchased outside of the U. S.,
contact your local distributor for information.
QuickStart
If you’ve had some prior experience using wireless systems, these QuickStart
instructions will get you up and running with your AirLine Synth UHF guitar system in
a matter of minutes! Detailed instructions for setting up and using your AirLine Synth
system can be found on page 15 of this manual, and the “Guided Tour” sections on
pages 4 - 11 provide full descriptions of all AirLine component controls and displays.
1.	Unpack the AR300 receiver and AG300
transmitter and configure the AG300 for
Fender Strat™ or flat jack style guitars.
If you need to change the phone plug
configuration, simply remove the
thumbscrew, unscrew the plug and
reinstall the two components while
swapping their positions.
2.	Physically place the AR300 receiver on your
amp or in front of you. Extend its antennas
vertically and spread the tips horizontally
outwards.
3. S et the power switch on your AG300
transmitter to the “off” position (away from
the arrow) and place a fresh AA battery
in it. Then turn the transmitter back on
momentarily; its LED will flash once and then go off if the battery is sufficiently
strong. Once battery strength is verified, turn the transmitter off again, then put it
aside for now.
4.	Connect the included AC power supply to the rear of the AR300 and then to an
available wall socket. Turn the AR300 on momentarily to confirm that the unit has
power. Then turn the AR300 power off.
5.	Turn your amplifier or mixer off and make the physical cable connection between
an audio input and the AR300 output jack.
6.	Turn the Level knob on the AR300 completely counterclockwise, then turn its
power on.
QuickStart
7. 	Now to set the channel, press and hold
the EDIT control until the display shows
the Group number with three asterisks.
Next, the AR300 will automatically find the
clearest channel and you will see it in the
Channel number of the display just before
the IR SET will begin.
8. 	Once you see the IR SET flashing in the
LCD display, hold the transmitter, with the
control switches facing you, approximately
6 inches away from the receiver and turn
the AG300 power switch on. The AR300
will transmit the channel number to AG300
over infrared light and you will see the
corresponding absolute channel number in
the transmitter LCD.
8. 	Turn on the connected amplifier or mixer but keep its volume all the way down.
Set the output level of your instrument to maximum and begin playing at a
normal performance level while observing the AF Meter. If the AF Meter reads
above “0” (indicating a Peak condition) even with the AR300 Level control fully
counterclockwise, engage the 15 dB pad on the transmitter. If not, slowly adjust
the GAIN inside the AG300 to the point where the AF Meter occasionally reads “0”
during the very loudest passages, then back it off just slightly. Finally, raise the
level of your connected amplifier and/or mixer until the desired volume is reached.
9. 	Do a walkaround through the intended area of coverage while observing the
receiver’s RF Meter; it should continue to read about “75%”, indicating sufficient RF
reception in all areas of coverage. If not, reposition the AR300 or its antennas as
necessary.
10.	If you hear any spurious noise from the receiver output when the transmitter
is turned off, use the supplied plastic screwdriver to adjust the AR300 Squelch
Guided Tour - AR300 Receiver / Front Panel
1. 	Antennas (A and B) - The antenna mountings allow full rotation for optimum
placement. In normal operation, both Antenna A (the antenna on the left) and
Antenna B (the antenna on the right) should be placed in a vertical position. Both
antennas can be folded inward for convenience when transporting the AR300. See
the “Setting Up and Using the AirLine Synth System” section on page 15 in this manual
for information about antenna installation and positioning.
2: 	Squelch – This control determines the maximum range of the AR300 before audio
signal dropout. Although it can be adjusted using the supplied plastic screwdriver,
it should normally be left at its factory setting. See the “Setting Up and Using the
AirLine Synth System” section on page 15 in this manual for more information.
3: 	Group Channel - This displays shows the current Group and Group Channel
number. A letter indicates Groups A through F and the Group Channel number are
indicated by 1 through 9 plus 0 for 10.
4: 	Antenna indicators – In order to maximize reception and distance, the AR300
implements true diversity receiver technology with dual RF strips. The A and B
antenna icon shows which of the receiver’s two RF strips is active.
5: 	Absolute Channel – This display shows the exact channel number from the 319channel plan.
Guided Tour - AR300 Receiver / Front Panel
6: 	EDIT Control – This rotary encoder control knob/switch is used to control and set
several menu functions and parameters displayed in the LCD display and it is also
used to preform the automatic Channel Scan.
7: 	Power Switch - Use this to turn the AR300 power on and off. When the receiver is
on, the LCD backlight is lit.
8: 	IR Transmitter – During “IR SET” an Infrared light is used to set the transmitter
channel.
9: 	RF Meter – 10-segment bar meter used to display the level of the radio frequency
reception.
10: 	LCD Display – The 47mm x 17mm backlit display show information for Frequency,
Channel, Group, Absolute Channel, Anntena, AF, RF, Scan, and IR Set.
11:	AF Meter - 10-segment bar meter used to display the amount of the audio input
level.
12:	Level control - This knob sets the level of the audio signal being output through
both balanced output connectors on the rear panel (see C and D on page 12 in
this manual). Reference level is obtained when the knob is turned fully clockwise
(to its “10” setting).
Guided Tour - AR300 Receiver / Rear Panel
A:	Antenna socket - D hole knockout for mounting the antennas to the rear panel
using the optional rear antenna kit.
B:	DC input - Connect the supplied power adapter here, using the strain relief as
shown in the illustration below. WARNING: Do not substitute any other kind of
power adapter; doing so can cause severe damage to the AR300 and will void your
warranty.
C: 	1/4-inch output* - Use this 1/4" jack when connecting the AR300 to your guitar
amp or to line level equipment. The output connection can be either balanced or
unbalanced. Wiring is as follows: tip hot, ring cold, sleeve ground.
D: 	XLR output* - Use this electronically balanced low impedance (600 Ohm) XLR jack
when connecting the AR300 to professional (+4) audio equipment. Pin wiring is as
follows: Pin 1 ground, Pin 2 high (hot), and Pin 3 low (cold).
E: 	Audio Output Level switch - Sets the audio output level attenuation of the XLR
output to -20 dBm (line level) or -40 dBm (mic level). See “Setting Up and Using the
AirLine Synth System” on page 15.
* If required, both outputs can be used simultaneously.
Guided Tour - AG300 Transmitter
1: 	¼-inch Phone Plug - Insert this standard 1/4” plug into your electric guitar or
electric bass. Note that the angling of the plug can be configured for Fender
Stratocaster™-type recessed jacks, and in a second position designed to be used
with all other instruments that have end mount-jacks. If you need to change the
phone plug configuration, simply remove the thumbscrew, unscrew the plug and
reinstall the two components while swapping their positions.
2: 	LCD Display – This three digit Liquid Crystal Display indicates the Absolute
Channel number that the transmitter is set to.
3: 	Power / Battery LED - This red LED flashes once when the AG300 is first turned
indicating the transmitter has power. It will remain off as long as they battery is a
good operating level. The LED lights steadily red when there are less than 2 hours
of battery power remaining, indicating that the battery needs to be changed. In
order to avoid compromising audio fidelity (or having the AG300 stop working
completely), you should always replace the battery with a fresh one immediately
whenever this LED lights red.
4: 	Mute switch – This switch is used to temporarily turn off the audio output of the
transmitter. Move this switch in the direction of “MUTE” to turn off the output and
move the switch in the direction of “ON” to turn the output on.
5: 	Power switch - Move this switch in the direction of the arrow to turn the AG300
power on; move it away from the arrow to turn the power off.
6: 	Antenna - This permanently attached flexible antenna should be fully extended
during normal operations. See the “Setting Up and Using the AirLine Synth System”
Guided Tour - AG300 Transmitter
section on page 15 in this manual
for more information about antenna
positioning.
7: 	Battery cover - Pull back gently on this
cover at the ribbing and pry upwards
to remove. See the “Setting Up and
Using the AirLine Synth System”
section on page 15 in this manual.
8: 	Battery compartment - Insert a
standard AA alkaline battery here,
being sure to observe the plus and
minus polarity markings shown.
We recommend the Duracell type
battery. Although rechargeable NiCad batteries can be used, they do not
supply adequate current for more than
four hours of operation. WARNING:
Do not insert the battery backwards;
doing so can cause severe damage to
the AG300 and will void your warranty.
10
9: 	15 dB Pad - Located under the battery
is a miniature slide switch to adjust the
AG300’s input sensitivity. Move this
11
switch in the direction of the arrow to
reduce the output of the AG300 by 15
dB when your instrument is putting
out too hot a signal. In general, if
you have single coil pick-ups, you’ll
probably want set the PAD to “OFF”. If
you have super hot humbuckers, you’ll probably want to switch the PAD on. See
the “Setting Up and Using the AirLine Synth System” section on page 15 in this manual.
10: G
 ain control - This miniature trimmer is used to fine tune the AG300’s input
sensitivity. Use the included screwdriver to make the adjustments.
11: I R Lens - This acrylic window is used to capture the infrared signal sent from the
AR300 during the IR SET to channelize the AG300.
Setting Up and Using Your AirLine Synth System
The basic procedure for setting up and using your AirLine Synth system takes only a
few minutes:
1. 	Remove all packing materials (save them in case of need for future service) and
check to make sure that the supplied power adapter is the correct voltage for your
country. If not, contact your distributor or, if purchased in the United States, Samson
Technical Support at 1-800-372-6766.
2. 	Physically place the AR300 receiver on your amp or on the ground in front of you
next to your pedal board. The general rule of thumb is to maintain “line of sight”
between the receiver and transmitter so that the person using the transmitter can
see the receiver.
3. 	Extend the AR300 antennas and spread the tips horizontally outwards at least 5
inches.
4. 	Make sure the Power On-Off switch in your AG300 transmitter is set to “Off” and
that the MUTE is also to “ON”. Pull back gently on the AG300 battery cover at the
ribbing and pry it upwards to remove it. Please use care when opening this cover
as undue force can damage it. Install a fresh AA alkaline battery in the battery
compartment, being sure to observe the polarity markings. Then carefully replace
the battery cover and gently press down on it until it clicks. Momentarily turn on
the power to the transmitter by sliding its Power On-Off switch in the direction of
the arrow; the “Power/Battery” LED will flash if the battery is sufficiently strong (if it
lights steadily, the battery has less than 2 hours of power remaining and should be
replaced). Once battery strength is verified, turn the transmitter off again and place
it aside for now.
5. 	With the Power switch on the AR300 set to the “Off” position, connect the included
power adapter. Turn the AR300 on momentarily to confirm that the unit is receiving
power. You’ll see the LCD display light up. Then turn the AR300 power off.
Setting Up and Using Your AirLine Synth System
6. 	Make the physical cable connection between the AR300 output jack and an audio
input of your amplifier or mixer. Leave your amplifier or mixer off at this time.
7. 	Turn the Level knob on the AR300 completely counterclockwise, then set its Power
switch up to turn it on. The LCD display light will illuminate.
8. 	Now to set the channel, press and hold the EDIT control until the display reads CH
SCAN. Next, the AR300 will automatically find the clearest channel and you will see
it in the Channel number of the display just before the IR SET will begin.
9. 	Once you see the IR SET flashing in the LCD display, hold the transmitter, with the
control switches facing you, approximately 6 inches away from the receiver and
turn the AG300 power switch on. The AR300 will transmit the channel number to
AG300 over infrared light and you will see the corresponding absolute channel
number in the transmitter LCD.
10.	The RF Meter on the AR300 receiver should now be active, indicating that it is
receiving valid RF signal and is placed and positioned correctly.
11.	Now it’s 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 AR300 AF Meter. If all the bars are lit, indicating a Peak condition, even with
the AR300 Level control fully counterclockwise, engage the 15 dB pad on your
transmitter by sliding the switch in the direction of the arrow. (In general, if you
have single coil pick-ups, you’ll probably want set the PAD to “OFF”. If you have
supper hot humbuckers, you’ll probably want to switch the PAD on.) If the AF Meter
bars are not all lit, slowly turn the AG300’s Gain control clockwise to the point
where the AF Meter reaches ‘‘0” during the very loudest passages, then back it off
just slightly; this will ensure maximum signal to noise ratio. Now, raise the Level on
the AR300. Finally, raise the level of your amplifier and/or mixer until the desired
volume is reached.
12.	If you hear distortion or the AR300 AF Meter is reaching “0” with the 15 dB pad
engaged and the TX Gain control at minimum (fully counterclockwise), reduce the
output level of your instrument until AF Meter is reading less than “0”. 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 AG300 Gain control is turned up.
10
Setting Up and Using Your AirLine Synth System
13.	Temporarily turn down the level of your amplifier or mixer and turn off the power
to your transmitter, leaving the AR300 receiver on. Then restore the previously
set level of your amplifier or mixer. With the transmitter off, the receiver output
should be totally silent; if it is, skip ahead to the next step. If it isn’t (that is,
if you hear some noise), you may need to adjust the AR300 Squelch control.
When the Squelch control is at its minimum setting, the AirLine Synth system
always provides maximum range without dropout; however, depending upon
the particular environment your system is used in, you may need to reduce that
range somewhat in order to eliminate band noise when the AG300 transmitter is
turned off. To do so, use the provided screwdriver to rotate the Squelch control
completely counterclockwise (to the “Min” position), then slowly turn it clockwise
until the noise disappears. If no noise is present at any position, leave it at its fully
counterclockwise “Min” position (so as to have the greatest overall range available).
14.	When first setting up your AirLine Synth system in a new environment, it’s always
a good idea to do a walkaround in order to make sure that coverage is provided
for your entire performance area. Accordingly, turn down the level of your audio
system and turn on both the transmitter and receiver. Then restore the level
of your audio system and while playing your electric guitar or bass at a normal
performance level, walk through the entire area that will need to be covered. As
you do so, observe the RF Meter on the AR300 receiver to make sure that it is close
to reaching “75%”, indicating that it is receiving sufficiently strong RF signal. Always
try to minimize the distance between transmitter and receiver as much as possible
so that the strongest possible signal is received from all planned transmission
points. In certain environments, it may be desirable to angle the AR300’s antennas
differently from the vertical position.
If you have followed all the steps above and are experiencing difficulties, contact your local
distributor or, if purchased in the United States, call Samson Technical Support (1-800-3726766) between 9 AM and 5 PM EST.

AR300 Operation
Setting a Group and Channel Manually
The AR300 receiver contains over 300 selectable channels that are organized into a
series of Groups. Each Group contains channels that are compatible for simultaneous
use. When using multiple systems, you’ll want to assign each system to the same Group
in order to maximize the number of compatible channels. Each of the Groups has six
to ten channels. The Group is designated with a letter, followed by the Group Channel
number 0-9 which is displayed under the “GROUP” icon in the AR300 LCD display.
To the right of the Group and Group Channel number is the read out Absolute channel
number. This three-digit Absolute Channel number corresponds to the exact channel
from the entire 320 channel plan. That Absolute Channel number is shown on the
AG300 transmitter’s LCD display.
The AG300 displays the Absolute Channel number it its LCD for a few seconds, and
then the display shuts off to preserve battery power. You can also see the transmitters
Absolute Channel number by switching the Mute on. In addition, the AG300 will also
display the Absolute Channel number briefly when the power is shut off.
1.	Press the EDIT control once and you will see the Group and Group Channel Number
Flash.
2.	Turn the EDIT controller and you will see the Group and Group Channel number
change, and you will also see the Absolute Channel number change in sync.
3.	If you prefer, you can choose the Absolute Channel. Simply press the EDIT control
again until the Absolute Channel number flashes. Then, turn the EDIT controller
and you will see the Absolute Channel number change. It changes in sync with the
Group Channel number.
4.	Once you have the desired channel set on the AR300 you’re ready to transmit the
infrared channel data to the AG300. Have the transmitter ready in your hand with
the Power switch set to off.
5.	Double click the EDIT controller and you see the display flash “IR SET” indicating that
the AR300 is sending the channel information over infrared transmission.
6.	Now, position the transmitter about 6-inches from the front of the AR300 with the
AG300 IR receiver facing the AR300’s LCD display and turn the power switch on.
You will now see the corresponding Absolute Channel in the AG300 LCD display
indicating that the transmitter is matched to the receiver.
12
AR300 Operation
Operating In FREE Mode
You can tune in an exact frequency using the AR300’s FREE mode. Once you are in FREE
mode you can change the frequency by 25 kHz steps. For most situations, it’s better to
use the GROUP Channel plan but if your application requires an exact frequency, follow
these steps to operate in FREE mode.
1.	Press the EDIT controller three times until the display’s FREE icon turns on and
Frequency number flashes.
2. Next, turn the EDIT controller until you reach the desired frequency number.
3.	Once you have the desired frequency set on the AR300 you’re ready to transmit the
infrared channel data to the AG300. Have the transmitter ready in your hand with
the Power switch set to off.
4.	Double click the EDIT controller and you see the display flash “IR SET” indicating that
the AR300 is sending the channel information over infrared transmission.
5.	Now, position the transmitter about 6-inches from the front of the AR300 with the
AG300 IR receiver facing the AR300’s LCD display and turn the power on.
You will now see the corresponding Absolute Channel in the AG300 LCD display
indicating that the transmitter is matched to the receiver.
If you want to see the Absolute channel while the AR300 is in Free Mode, simply turn
the EDIT control and it will toggle between the exact Frequency and the Absolute
Channel.
To exit FREE Mode, just press the EDIT controller switch and you will return to the Group
and Absolute Channel fields. Once you are in the Group Channel or Absolute Channel
field and you have selected your channel, double click the EDIT control to perform the
IR set and lock in the channel. You can also use the Scan function to find a clear channel
by pressing and holding the EDIT knob. If you do not perform an IR set or Channel
Scan, the AR300 will return to Free Mode and the channel will be set to the previously
selected frequency.
