Introduction

Samson AirLine

1

ENGLISH

Welcome to Samson AirLine—the wireless system for the new millennium! Wireless microphone and instrument systems were
originally developed to eliminate cables, providing unparalleled freedom of movement. AirLine takes this concept to a new level with
transmitters and receivers so small, lightweight and aerodynamic, they are nearly invisible, providing a completely “hassle-free” user
experience. To create the world’s smallest wireless systems, we developed new proprietary technology. Featuring miniaturized circuitry
and the ability to operate on a single tiny AAA battery (with 14 hours typical battery life), these systems also feature significantly
improved wireless reception and sound quality. What’s more, the AM1 micro receiver developed especially for the AirLine system is as
small as the AL1 transmitter.

There are two different Samson AirLine systems detailed in this manual. Both operate in the 801 - 805 MHz UHF frequency range
and each contains an AM1 micro receiver. The AirLine UHF Microphone System contains an AX1 hand-held transmitter, which plugs
into any standard wired dynamic microphone. The AirLine UHF Presentation System contains an AL1 presentation transmitter, which
contains a built-in electret condenser microphone and connection for an optional lavalier microphone.

In this manual, you’ll find a more detailed description of the features of all AirLine systems, as well as a guided tour through all com­ponents, step-by-step instructions for setting up your system and full specifications. If your AirLine 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 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 system ever require servicing, a

Return Authorization number (RA) is
necessary. Without this number, the unit will not be accepted. If your AirLine 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 system was purchased outside of the U. S., contact your local distributor for information.

Quick Start

Samson AirLine

ENGLISH

If you’ve had some prior experience using wireless systems, these QuickStart instructions will get you up and running with your
AirLine system in a matter of minutes! Detailed instructions for setting up and using your AirLine system can be found on page 11 of
this manual, and the “Guided Tour” sections on pages 4 - 16 provide full descriptions of all AirLine component controls and displays.

1. Make sure that the AM1 receiver and AX1 and/or AL1 transmitter are factory preset to the same channel.

2. Place a fresh battery in the AM1 receiver. Place the receiver where it will be used. The AM1 receiver can be mounted to the hot
shoe of the camera, clipped with the supplied clip or fastened by the use of the supplied velcro.

3. Set the power switch to your transmitter to the “off” position (away from the arrow) and place a fresh 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.

4. If you are using an AX1, plug its XLR connector into a wired dynamic microphone; make a good tight connection, using the sup-

plied rubber gasket if necessary. If you are using the AL1 with an external lavalier microphone, make the physical connection
between its input connector and the microphone.

5. Make the physical cable connection between the AM1 receiver’s 2.5mm stereo output jack and audio input of your camera or
mixer using the supplied 2.5mm to 3.5mm SMM14 cable (see wiring diagram on page 19 for options).

6. Select the correct gain by using the MIC/LINE switch on the AM1 receiver to match the input of your camera or mixer.

ENGLISH

7. Turn on the receiver. The POWER/BATTERY LED will light momentarily indicating the power has been turned on.

8. Turn on your transmitter. The audio signal can be monitored through the 3.5mm stereo headphone output and headphone volume
can be adjusted via the headphone level trim pot with the supplied plastic screwdriver.

9. Turn on your camera or mixer but keep its volume all the way down. If your system contains an AL1 transmitter, make sure it is
unmuted. Set the Volume, Level or AF Level knob on the receiver fully clockwise; this is unity gain.

10. Speak or sing into your mic at a normal performance level while slowly raising the audio input control of your camera (if you
have one) or mixer until the desired level is reached. If necessary, use the supplied plastic screwdriver to adjust the transmitter’s
Gain trimpot in order to increase or decrease its signal level. If you are using an AL1 transmitter with the built-in microphone,
correct placement is critical to sound quality. It should be unobstructed by clothing and either clipped to a shirt pocket or lapel,
or worn around the neck on the supplied lanyard.

11. Do a walkaround through the intended area of coverage while monitoring the audio signal via the AM1 receiver headphone out­put or input level meter (if one is available).

1: Power On/RF/ Battery LED - This LED flashes once when the AL1 is first turned on and
lights steadily red when there is less than 2 hours of battery power remaining, indicating that
the battery needs to be changed.

2: Antenna - This permanently attached flexible antenna should be fully extended during
normal operations. See the “Setting Up and Using Your AirLine System” section on page 11
in this manual for more information about antenna positioning.

3: Electret condenser microphone - This high- quality unidirectional electret condenser
microphone with metal windscreen is optimized for clear, crisp reproduction of speech. It
is active whenever the AL1 is powered on, as long as there is no connection made to the
lavalier microphone input connector (see #4 below). When a plug is inserted into the
lavalier microphone input connector, this built-in microphone is muted.

4: Lavalier microphone input connector - Use this
standard 2.5 mm mini-jack if you want to connect
an external lavalier microphone to the AL1.
Note that, because the AL1 has a built-in electret
condenser microphone (see #3 above), the use of an
external lavalier mic is optional and not required.
The AL1 provides 2.7V of phantom power, so
condenser mics can be used if desired.

Setting up and Using your AirLine System

Samson AirLine

11

ENGLISH

The basic procedure for setting up and using your AirLine System takes only a few minutes:

1. For your AirLine system to work correctly, both the receiver and transmitter must be set to the same channel. Remove all packing

materials (save them in case of need for future service) and check to make sure that the supplied receiver and transmitter are set to
the same channel (a complete channel plan is printed on the inside back cover of this manual). If these channels do not match,
contact your distributor or, if purchased in the United States, Samson Technical Support at 1-800-372-6766.

2. Place a fresh AAA alkaline battery in the AM1’s battery compartment, taking care to observe the polarity markings, and physically

place the receiver where it will be used (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). The AM1 can be mounted on hot shoe of a video camera
using the supplied hot shoe clip, worn as a belt pack using the belt clip or fixed to any location with the supplied velcro.

3. Bend the antenna in a vertical position. Make sure the Power on-off switch in your transmitter is set to “Off.”

4a. If your system contains an AX1 handheld transmitter, unscrew the bottom section by turning it counterclockwise and then slide it off.

4b. If your system contains an AL1 body pack transmitter, turn it over and slide off the battery door.

5. Place a fresh AAA alkaline battery in the transmitter battery compartment, taking care to observe the polarity markings. If you are

using an AX1 transmitter, replace the bottom section by sliding it on and then screwing it back on. If you are using an AL1 trans­mitter, replace the battery door by sliding it in until it clicks. Whichever transmitter you are using, leave it off for the moment.

6. Make the physical cable connection between the receiver output jack and a mic or line level audio input of your camera or mixer
(see wiring diagram on page 19 for options). Be sure to set the receiver’s Line/Mic switch correctly (see pages 4 for details). Leave
your camera (and/or mixer) off at this time.

7. Slide the Power switch in the direction of the arrow to turn on the receiver. The “Power/ RF” LED will light red momentarily.

8. Turn on the power to your transmitter (using its Power on-off switch); 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). The “Power/ RF” LED
on the receiver should light green, indicating that it is receiving valid RF signal and is placed and positioned correctly.

9. Now it’s time to set the audio levels. Turn on your
connected camera and/or mixer but keep its volume
all the way down. If you are using an AL1 transmit­ter, make sure that it is unmuted (its Mute switch
should be positioned away from the arrow). If you
are using an AL1 transmitter with the built-in micro­phone, note that correct placement is critical to
sound quality. We recommend that you place it as
shown in the illustrations on this page—unobstruct­ed by clothing and either clipped to a shirt pocket
or lapel, or worn around the neck on the supplied
lanyard.

10. Speak or sing into your mic at a normal performance level while slowly raising the volume of your camera and/or mixer until the
desired level is reached. The AM1 receiver allows you to monitor the transmission signal using standard Walkman-type 30 ohm
headphones connected to its headphone jack. Note that Unidirectional microphones (mics which pick up signal from just one
direction) such as the built-in AL1 electret condenser are less prone to feedback than other types of mics. Any feedback problems
you encounter can be minimized by being sure not to use the microphone directly in front of a PA speaker or by using an equal­izer to attenuate (reduce) those high- or mid-range frequencies which are causing the feedback “squealing”.

11. If you hear distortion at the desired volume level make sure that the gain structure of your audio system is correctly set (consult
the owners manual of your mixer and/or camera for details). If distortion persists try the following:

• If you are using an AX1 transmitter, use the supplied plastic screwdriver to turn its Microphone Input Level control (trimpot) slowly
counterclockwise (towards the “Min” position) until the distortion disappears.

• If you are using an AL1 transmitter with its internal electret condenser microphone, simply move the microphone further from
your mouth. If you are using an AL1 with an external lavalier microphone, use the supplied plastic screwdriver to turn the Gain
control (trimpot) slowly counterclockwise until the distortion disappears.

12. Conversely, if you hear a weak, noisy signal at the desired volume level, again make sure that the gain structure of your camera
and/or audio system is correctly set (consult the owners manual of your mixer and/or amplifier for details) If the signal coming
from the receiver is still weak and/or noisy, do the following:

• If you are using an AX1 transmitter, use the supplied plastic screwdriver to turn its Microphone Input Level control (trimpot) slowly
clockwise (towards the “Max” position) until the signal reaches an acceptable level.

Setting up and Using your AirLine System

ENGLISH

• If you are using an AL1 transmitter with its internal electret condenser microphone, simply position the microphone closer to your
mouth. If you are using an AL1 with an external lavalier microphone, use the supplied plastic screwdriver to turn the Gain control
(trimpot) slowly clockwise until the signal reaches an acceptable level.

13. When first setting up your AirLine 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, with the transmitter unmuted, restore the level of your audio system and while speaking or
singing, walk through the entire area that will need to be covered. As you do so, observe the LED on the receiver to make sure
that it is receiving sufficiently strong RF signal (the AM1 receiver “Power On / RF / Low Battery” LED should always remain lit
steadily green). 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.

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 (1-800-372-6766) between 9 AM and 5 PM EST.

Introduction

Merci d’avoir fait confiance au système Samson AirLine — le système sans fil du nouveau millénaire ! Les systèmes sans fil pour
micros et instruments ont été créés afin d’éliminer les câbles et offrir ainsi aux artistes une liberté de mouvement totale. Les systèmes
AirLine portent ce concept au stade ultime grâce à des émetteurs et des récepteurs si petits, légers et aérodynamiques qu’ils en sont
presque invisibles. Ces systèmes sans fil les plus compacts du marché bénéficient d’une toute nouvelle technologie brevetée. De plus,
grâce à l’emploi de circuits miniaturisés et de leur capacité à fonctionner à partir d’une seule pile AAA (pour une autonomie moyenne
de 14 heures), ces systèmes offrent une qualité de réception et une qualité sonore grandement améliorées. Ajoutons que le récepteur
micro AM1 développé tout spécialement pour le système AirLine est aussi petit que l’émetteur AL1.

Ce mode d’emploi porte sur deux systèmes AirLine Samson différents. Ces deux systèmes fonctionnent sur une bande de fréquences
UHF située entre 801 et 805 MHz et disposent chacun d’un récepteur micro AM1. Le système Microphone UHF AirLine est constitué
d’un émetteur main AX1 à brancher sur n’importe quel micro dynamique standard. Le système Presentation UHF AirLine est constitué
d’un émetteur de présentation AL1 équipé d’un micro condensateur à électret interne et d’un connecteur pour micro cravate.

Le présent manuel vous donne les caractéristiques de tous les systèmes AirLine, une visite guidée des éléments du système, la descrip­tion détaillée du paramétrage des systèmes et les caractéristiques techniques. Si vous avez acheté votre système AirLine aux Etats­Unis, n'oubliez pas de remplir et de nous renvoyer la carte de garantie incluse. Vous pourrez grâce à elle bénéficier de notre assis­tance technique et être tenu au courant des dernières nouveautés Samson. Si vous avez acheté votre système AirLine hors des Etats­Unis, contactez votre revendeur pour de plus amples détails sur les clauses de la garantie. Vous pouvez également trouver des ren­seignements complets sur notre gamme de produits sur notre site Internet accessible à l’adresse http://www.samsontech.com.

Si vous êtes un habitué des systèmes sans fil, ce chapitre va vous permettre de configurer et d’utiliser votre système AirLine en
quelques minutes. Vous pouvez trouver les procédures de configuration et d’utilisation détaillées à partir de la page 11 du présent
mode d’emploi, ainsi qu’un “tour d’horizon” des commandes et des caractéristiques des systèmes AirLine.

1. Vérifiez que le récepteur AM1 et l’émetteur AX1 et/ou AL1 sont bien réglés d’usine sur le même canal.

2. Placez une pile neuve dans le récepteur AM1 et installez le récepteur à l’endroit où il doit être utilisé. Le récepteur AM1 peut être
monté sur une caméra au moyen de la pince ou de l’attache Velcro fournies.

3. Vérifiez que l’émetteur est hors tension (son interrupteur d’alimentation ne doit pas être dirigé vers la flèche), puis placez-y une
pile neuve. Mettez momentanément l’émetteur sous tension. Son témoin doit s’allumer brièvement puis s’éteindre si la pile est
suffisamment puissante. Une fois que vous avez vérifié l’état de la pile, éteignez l’émetteur.

4. Si vous utilisez un AX1, reliez un micro dynamique à son connecteur XLR. Assurez bien la connexion, si besoin est, au moyen du
joint en caoutchouc fourni. Si vous avez l’intention d’utiliser l’AL1 avec un micro cravate externe, reliez ce micro cravate à son
connecteur d’entrée.

5. Faites ensuite la connexion physique entre la sortie stéréo sur Jack 2,5 mm de l’AM1 et l’entrée audio de votre caméra ou de votre
console de mixage par le biais du câble SMM14 2,5 mm-3,5 mm fourni (vous pouvez en trouver le schéma de câble en page 19).

6. Adaptez le gain du récepteur AM1 à celui de l’entrée de la caméra ou de la console au moyen de son sélecteur MIC/LINE.

Samson AirLine

20

FRANCAIS

Prise en main

7. Mettez ensuite le récepteur sous tension. Le témoin POWER/BATTERY s’allume temporairement pour signaler que l’appareil est
sous tension.

8. Mettez l’émetteur sous tension. Vous pouvez avoir le retour du signal audio sur la sortie casque stéréo 3,5 mm. Une vis de
réglage permet de définir le volume de cette sortie (au moyen du tournevis en plastique fourni).

9. Allumez ensuite la caméra ou la console sans pour autant relever leur volume. Si votre système est constitué d’un émetteur AL1,
vérifiez que sa sortie n’est pas coupée, puis réglez-le au gain unitaire (potentiomètre Volume, Level ou AF placés complètement à
droite).

10. Parlez ou chantez dans le micro à niveau normal tout en relevant progressivement le volume de la caméra (si elle en est pourvue
d’un) ou de la console de mixage jusqu'au niveau désiré. Si besoin est, ajustez le niveau du signal au moyen de la vis de réglage
Gain et du tournevis en plastique fourni. Si vous utilisez un émetteur AL1 avec son micro interne, la qualité sonore finale dépend
en grande partie du bon placement de l’émetteur. Il ne doit pas obstrué ou être recouvert par des vêtements et doit être fixé à une
poche de chemise ou à une cravate ou bien porté autour du cou au moyen du cordon fourni.

11. Parcourez toute la surface devant être couverte tout en vérifiant le signal audio au niveau de la sortie casque ou de
l’afficheur de niveau d’entrée du récepteur AM1.
