Introduction Samson AirLine

Welcome to Samson AirLine—the wireless system for the new millenium! 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 so small, lightweight and aerodynamic, they are nearly invisible, providing a completely“hassle-free”user experience. To create the world’s smallest wireless transmitters, 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 transmitters also feature significantly improved wireless reception and sound quality.

There are three different Samson AirLine systems detailed in this manual. All operate in the 801–805, 863–865 MHz UHF frequency range and all contain either a CR77 true diversity receiver (for professional performance applications) or a UM1 micro diversity receiver (optimized for the production of professional audio tracks to accompany your video shoot or live broadcast). The AirLine UHF Performance System combines a feather-light AH1 headset transmitter with a Samson QV headset microphone, while the AirLine UHF Fitness System combines the AH1 with a Samson QE headset microphone. The AirLine UHF Wind Instrument System combines the AH1 with a Samson HM40 horn microphone. It is the first wireless system designed for brass and reed instruments that eliminates the need for a body pack and unwieldy microphone cables that limit your movement.

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.

Samson AirLine QuickStart

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 14 of this manual, and the“Guided Tour”sections on pages 4 - 13 provide full descriptions of all AirLine component controls and displays.

1.Make sure that the supplied receiver and AH1 transmitter are factory preset to the same channel.

2.Physically place the receiver where it will be used and extend its antenna(s) vertically.

3.Set the power switch on your UH1 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 again.

4.If you are using an AH1 headset microphone, position it correctly as per the illustrations on page 12. If you are using an AirLine

UHF Wind Instrument System, clamp the horn mic to your instrument as described in the supplied HM40 owners manual.

5.Turn your audio system off and make the physical cable connection between the receiver’s balanced or unbalanced output jack (if necessary, both can be used simultaneously) and a mic level audio input of your amplifier or mixer. If your system contains a CR77 or UM1 receiver, be sure to set its Audio Output Level switch correctly.

6.Turn the Volume, Level or AF Level knob on the receiver completely counterclockwise. Connect the supplied AC adapter to the receiver and plug it in (or place a fresh battery in the UM1 receiver), but leave its power off for the moment.

7.Turn on the receiver. If your system contains a CR77 receiver, its“Power”LED will light steadily red. (Note: the UM1 receiver has no such LED.)

QuickStart	Samson AirLine
8. Turn on your AH1 transmitter. If your system contains an AR1 receiver, its“Power/ RF”LED should change color from red to green, indicat-		ENGLISH
ing that it is receiving valid RF signal and is placed and positioned correctly. If your system contains either a CR77 or UM1 receiver, one of

the“A/B Receiver”LEDs will be lit, showing you whether the (left)“A”or (right)“B”receiver is currently being used. The CR77 / UM1 meter will also indicate the strength of the incoming RF signal.

9. Turn on your connected amplifier and/or mixer but keep its volume all the way down. Make sure the AH1 transmitter 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 headset microphone (or play the instrument connected to the horn microphone) at a normal performance level while slowly raising the audio input control of your amplifier or mixer until the desired level is reached.

11. Do a walkaround through the intended area of coverage while observing the receiver’s“Power/RF”LED or RF Meter; it should indicate sufficient RF reception in all areas of coverage. Reposition it (or its antenna) as necessary. If extended range coverage is required, a Samson CR77 or UM1 true diversity receiver (set to the same channel as the transmitter) should be used

12. If you hear any spurious noise from the receiver output when the transmitter is turned off, use the supplied plastic screwdriver to adjust the receiver Squelch level control, slowly turning it clockwise to the point at which the noise disappears.

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 CR77. See the “Setting Up and Using the AirLine System”section on page 14 in this manual for information about antenna installation and positioning.

2: Volume control - This knob sets the level of the audio signal being

output through both the balanced and unbalanced output jacks on the rear panel (see #2 and #4 on page 6 in this manual). Reference level is obtained when the knob is turned fully clockwise (to its“10”setting).

3: Audio Meter - - This“ladder”display (similar to the VU bar meter used on audio devices) indicates the strength of the incoming audio signal. When the“0”segment is lit, the incoming signal is optimized at unity gain; when the“+6”segment is lit, the signal is overloading. When only the left-most“-20”segment is lit, the incoming signal is at just 10% of optimum strength. If no segments are lit, little or no signal is being received. See the“Setting Up and the AirLine System”section on page 14 in this manual for more information.

	4: Squelch control - This control determines the maximum range of the CR77 before audio signal dropout. Although it can be adjusted	ENGLISH
	using the supplied plastic screwdriver, it should normally be left at its factory setting. See the“Setting Up and Using the AirLine System”
	section on page 14 in this manual for more information.

5: A/B Receiver LEDs - When signal is being received, one of these will be lit green, showing you whether the (left)“A”or (right)“B”receiver is currently being used. The CR77 constantly scans its two antennas and automatically selects whichever is receiving the strongest, clearest signal. This True Diversity switching is completely inaudible, but it effectively increases overall range while virtually eliminating potential interference and phase cancellation problems.

6: RF (Radio Frequency) Level meter - This“ladder”display (similar to the VU bar meter used on audio devices) indicates the strength of the incoming radio signal. When the“100%”segment is lit, the incoming RF signal is fully modulated and at optimum strength. When only the second most left-most“10%”segment is lit, the incoming signal is at just 10% of optimum strength. If no segments are lit, little or no signal is being received. See the“Setting Up and Using the AirLine System”section on page 14 in this manual for more information.

7: Power switch - Use this to turn the CR77 power on and off. When the receiver is on, the internal Power LED is lit.

				doing so can cause severe damage to
				the CR77 and will void your warranty.

2: Unbalanced output* - Use this unbalanced high impedance (5K Ohm) 1/4" jack when connecting the CR77 to consumer (-10) audio equipment. Wiring is as follows: tip hot, sleeve ground.

3: Audio Output Level switch - Sets the audio output level attenuation of the balanced output (see #4 below) to -20 dBm (line level) or -40 dBm (mic level). See“Setting Up and Using the AirLine System”on page 14.

4: Balanced output* - Use this electronically balanced low impedance (600

Ohm) XLR jack when connecting the CR77 to professional (+4) audio equipment. Pin wiring is as follows: Pin 1 ground, Pin 2 high (hot), and Pin 3 low (cold).

* If required, both the unbalanced and balanced outputs can be used simultaneously.

GuidedTour - UM1 Receiver Samson AirLine

1: A/B Receiver LEDs - When signal is being received, one of these will be lit orange, showing you whether the (left)“A”or (right)“B”receiver is currently being used. The UM1 constantly scans its two antennas and automatically selects whichever is receiving the strongest, clearest signal. This True Diversity switching is completely inaudible, but it effectively increases overall range while virtually eliminating potential interference and phase cancellation problems.

2: Meter - This set of three multicolor LEDs acts as a meter, indicating either battery power or the strength of the incoming RF signal. This meter can also be disabled altogether to conserve battery power. See #15 on page 9 for more information.

3: Peak LED - This LED lights red when output signal from the UM1 is at the onset of clipping (that is, when it is on the verge of being distorted). If you see this light during operation, move the microphone further away or lower the output level of your instrument or transmitter. For more information, see the section entitled“Setting Up and Using the AirLine System”on page 14 in this manual.

4:Power switch - Use this to turn the UM1 power on and off.

5:SQ (Squelch) Level control - This control determines the maximum range of the UM1 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 System”section on page 14 in this manual for more information.

6:Battery holder - Insert a standard 9-volt alkaline battery here, being sure to observe the plus and minus polarity markings shown. We recommend the Duracell MN 1604 type battery. Although rechargeable Ni-Cad batteries can be used, they do not supply adequate current for more than four hours.

WARNING: Do not insert the battery backwards; doing so can cause severe damage to the UM1 and will void your warranty.

7:Plastic screwdriver - Specially designed for use in adjusting the UM1 Squelch Level control (see #4 on the previous page). See the“Setting Up and Using the AirLine System”section on page 14 in this manual for more information.

8:Antennas (A and B) - The antenna mountings allow full rotation for optimum placement. In normal operation, both antennas should be placed in a vertical position. Both antennas can be folded inward for convenience when transporting the UM1. See the“Setting Up and Using the AirLine”section on page 16 in this manual for more information.

9:DC input - This jack will accept a DC input voltage of 6 - 13 volts (inner connection [tip] positive, outer connection [sleeve] ground) from your video camera, if available. Connect an optional Samson AC300R adapter here to charge a rechargeable 9-volt Ni-Cad battery.

10:Unbalanced output* - Use this unbalanced (1K Ohm max.) 1/8" (3.5 mm) mini-phone jack when connecting the UM1 to consumer (-10) audio equipment. Wiring is as follows: tip hot, sleeve ground. If your video camera has stereo audio inputs, you’ll need to use a Y-adapter that has a 1/8" (3.5 mm) mini-phone plug at one end and dual male RCA-type plugs at the other end.

11:Audio Output Level switch - Sets the audio output level of both the balanced and unbalanced outputs (see #10 above and #14 on the following page) to -30 dBm (mic level), -20 dBm, or -10 dBm (line level). See the“Setting Up and Using the AirLine System”section on page 14 in this manual for more information.

4:Mute switch - Move this switch in the direction of the arrow to mute the AH1; move it away from the arrow to unmute it and transmit audio signal. Because the carrier signal remains during muting, no“pop”or“thud”will be heard. Note that turning this off does not turn off the transmitter power—it is simply a way to temporarily mute the transmission of audio signal. If you don’t plan on using the AH1 for extended periods, turn it off power by using the power on-off switch (see #5 below).

5:Power switch - Move this switch in the direction of the arrow to turn power to the AH1 on; move it away from the arrow to turn power off. (to conserve battery power, be sure to turn the AH1 off when not in use). Be sure to mute the audio signal at your external mixer or amplifier before turning the AH1 power on or off, or an audible pop may result.

Samson AirLine Setting Up and UsingYour AirLine System

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

ENGLISH 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 chan-

nel (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. 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 CR77 can be rack-mounted if desired (taking a half-rack space), using an optional Samson adapter kit. The UM1 can be mounted to a video camera using the supplied velcro.

3. Extend the receiver antenna(s) and place it (them) in a vertical position. Make sure the Power on-off switch in your AH1 transmitter is set to“Off.”

4. Gently pry off the battery cover off the AH1 transmitter and slide it upwards and off to open the battery compartment. Please use care when opening this cover as undue force will destroy the hinge.

5. Place a fresh AAA alkaline battery in the transmitter battery compartment, taking care to observe the polarity markings. Then replace the battery cover and gently press down on it until it clicks. Leave the AH1 off for the moment.

6. Make the physical cable connection between the receiver output jack and a mic level audio input of your amplifier or mixer. The balanced XLR jack is preferable, since it will deliver an electromagnetically cleaner signal. If required, both the balanced and unbalanced outputs can be used simultaneously. If your system contains a CR77 or UM1 receiver, be sure to set its Audio Output Level switch correctly (see pages 7 and 9 for details). Leave your amplifier (and/or mixer) off at this time.

7. Turn the Volume, Level or AF Level knob on the receiver completely counterclockwise. Connect the supplied AC adapter to the CR77 receiver and plug it in (the UM1 receiver can also operate off battery power or a 12 volt power supply from a connected video camera), then plug the adapter into any standard AC outlet. Slide the Power switch in the direction of the arrow to turn on the receiver. If your system contains a CR77 receiver, its“Power”LED will light steadily red. (Note: The UM1 receiver has no“Power”LED indicator.)

14

Setting Up and UsingYour AirLine System Samson AirLine
8. Turn on the power to your AH1 transmitter (using its Power on-off switch); the“Power/Battery”LED will flash if the battery is sufficiently	ENGLISH

strong (if it lights steadily, the battery has less than 2 hours of power remaining and should be replaced). If your system contains either a CR77 or UM1 receiver, one of the“A/B Receiver”LEDs will light, showing you whether the (left)“A”or (right)“B”receiver is currently being used. The CR77 / UM1 meter will also indicate the strength of the incoming RF signal.

9. Now it’s time to set the audio levels. Turn on your connected amplifier and/or mixer but keep its volume all the way down. Make sure that the AH1 transmitter is unmuted (its Mute switch should be positioned away from the arrrow). Then set the Volume, Level or AF Level knob on the receiver fully clockwise; this is unity gain.

10. Speak or sing into your headset mic (or play the instrument to which the horn mic is attached) at a normal performance level while slowly raising the volume of your amplifier and/or mixer until the desired level is reached. The UM1 receiver allows you to monitor the transmission signal using standard Walkman-type 30 ohm headphones connected to its headphone jack.

11. If you hear distortion at the desired volume level, first check to see whether the“Peak”LED on the receiver is lit . If it is not lit, make sure that the gain structure of your audio system is correctly set (consult the owners manual of your mixer and/or amplifier for details). If the “Peak”LED is lit, simply move the microphone further from your mouth.

12. Conversely, if you hear a weak, noisy signal at the desired volume level, again make sure that the gain structure of your audio system is correctly set (consult the owners manual of your mixer and/or amplifier for details) and that the Volume, Level or AF Level control of the receiver is fully clockwise. If it is and the signal coming from the receiver is still weak and/or noisy, simply position the microphone closer to your mouth.

13. Temporarily turn down the level of your mixer/amplifier system and turn off the power to your transmitter, leaving the receiver on. Then restore the previously set level of your mixer/amplifier. 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 receiver Squelch control. When the Squelch control is at its minimum setting, the AirLine 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 AH1

15

Samson AirLine Setting Up and UsingYour AirLine System

ENGLISH

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 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 RF display or meter on the receiver to make sure that it is receiving sufficiently strong RF signal (in the CR77 and UM1 receivers, all segments of the RF Level meter should be lit). 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 receiver antenna(s) differently from the vertical position. Where extended range coverage is required, the Samson CR77 true diversity receiver (set to the same channel as the transmitter) should be used. For videography applications, the Samson UM1 micro diversity receiver should be used.

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 Samson AirLine

Bienvenue sur Samson Airline. Envolez-vous vers la liberté grâce aux systèmes sans fil du nouveau millénaire ! Les microphones et instruments sans fil ont été inventés pour offrir aux musiciens et aux interprètes une liberté de mouvement totale. La gamme AirLine reprend ce concept et le porte à une dimension encore jamais égalée grâce à des émetteurs si petits, légers et aérodynamiques qu'ils sont quasiment invisibles ! Nous avons développé une toute nouvelle technologie qui a permis de créer des émetteurs aussi miniatures. Dotés de circuits miniaturisés et fonctionnant sur une simple pile AAA (autonomie moyenne de 14 heures), ces émetteurs bénéficient d'une qualité sonore et d'une qualité de réception vraiment améliorées.

Le présent mode d'emploi vous donne tous les renseignements nécessaires concernant trois modèles de la gamme Samson AirLine. Tous fonctionnent dans la bande de fréquences UHF 801 à 805, 863 à 865 MHz et reprennent le récepteur CR77 0 UM1 - soit un récepteur CR77 True Diversity (destiné aux applications professionnelles sur scène), soit un récepteur UM1 Diversity (optimisé pour la production d'enregistrements audio pour des plateaux de vidéo ou de diffusion en direct). Le système AirLine UHF Performance réunit le

AH1, émetteur serre-tête poids plume et un micro casque QV Samson, alors que le système AirLine UHF Fitness associe le AH1 à un micro casque QE Samson. Enfin, le système AirLine UHF Wind Instrument réunit un AH1 et un microphone HM40.

		ainsi que des "visites guidées" présentant les différentes commandes, connecteurs et témoins des modèles AirLine aux pages 20 à 29.
		1. Vérifiez que le récepteur et l'émetteur AH1 fournis sont bien réglés sur le même canal.
	FRANÇAIS	2.	Placez le récepteur à l'endroit où il devra être utilisé et déployez son antenne.
		3.	Mettez l'émetteur UH1 hors tension en réglant l'interrupteur d'alimentation sur "Off" (pas sur la flèche), puis placez-y une pile neuve.
		Faites alors repasser temporairement l'émetteur sous tension ; son témoin lumineux clignote une fois, puis s'éteint si la pile est suffisam-
		ment puissante. Lorsque la puissance de la pile a été vérifiée, mettez l'émetteur hors tension.
		4.	Si vous utilisez un microphone serre-tête AH1, positionnez-le conformément aux illustrations de la page 30. Si vous utilisez un système
		AirLine UHF Wind Instrument, fixez le micro à votre instrument selon les consignes indiquées dans le mode d'emploi HM40 fourni.
		5.	Placez votre système d'écoute hors tension, puis reliez la sortie symétrique ou asymétrique du récepteur (les deux sorties peuvent être
		employées simultanément si nécessaire) à l'une des entrées micro audio de votre amplificateur ou de votre console de mixage. Si votre sys-
		tème est équipé d'un récepteur CR77 ou UM1, vérifiez que son sélecteur de niveau de sortie est correctement réglé.
		6. Tournez le potentiomètre Volume, Level ou AF Level du récepteur complètement vers la gauche. Reliez l'une des extrémités de
		l'adaptateur secteur fourni au récepteur et l'autre à une prise secteur (ou placez une pile neuve dans le récepteur UM1). Laissez le récepteur
		hors tension pour l'instant.
		7.	Placez le récepteur sous tension. Si votre système est pourvu d'un récepteur CR77, son témoin "Power" doit alors s'allumer en rouge. Note

	8. Placez l'émetteur AH1 sous tension. Si vous êtes équipé d'un récepteur AR1, le témoin "Power/ RF" de l'AR1 doit alors virer au vert, ce
	qui indique qu'il reçoit un signal HF valide et qu'il est correctement positionné. Si vous êtes équipé d'un récepteur CR77 ou UM1, l'un des
	témoins "A/B Receiver" doit s'allumer, ce qui indique que l'un des deux canaux (gauche "A" ou droit "B") est en cours d'utilisation. L'afficheur
	de niveau des CR77/UM1 vous renseigne par ailleurs sur l'intensité du signal HF reçu.
	9. Activez ensuite l'amplificateur ou la console de mixage utilisé(e) sans pour autant relever le volume. Vérifiez que l'émetteur AH1 n'est pas
	coupé par la fonction Mute. Tournez alors le potentiomètre Volume, Level ou AF Level du récepteur complètement vers la droite (position
	qui correspond au gain unitaire).		FRANÇAIS
	10. Chantez ou prononcez des mots dans le micro (ou jouez de l'instrument sur lequel est fixé le microphone) au niveau auquel ils devront

l'être lors du concert ou de la conférence, tout en relevant progressivement le niveau de l'entrée audio de l'amplificateur ou de la console de mixage jusqu'au volume souhaité.

11. Faites quelques pas sur toute la zone à couvrir tout en observant le témoin "Power/RF" ou l'afficheur de niveau HF (RF Meter) du récepteur. Ce témoin (ou afficheur) doit toujours rester allumé en vert dans toutes les zones de couverture. Si nécessaire, repositionnez son ou ses antennes. Si vous avez besoin d'une plus grande couverture, remplacez l'AR1 par un récepteur True Diversity Samson CR77 ou UM1 (réglé sur le même canal).

12. Si vous entendez des émissions parasites à la sortie du récepteur lorsque l'émetteur est hors tension, relevez progressivement le potentiomètre Squelch du récepteur jusqu'à ce que les interférences disparaissent.

1: Antennes (A et B) - Les différents montages possibles des antennes permettent leur rotation complète pour obtenir une localisation optimale. En fonctionnement normal, l’antenne

A (située à gauche) et l’antenne B (située à droite) doivent être placées en position verticale. Les deux antennes peuvent être repliées vers l’avant, pour faciliter le transport du récepteur CR77. Voir la page 30 de ce manuel, pour plus d’information sur l’installation et le positionnement des antennes.

2: Volume - Cet indicateur détermine le niveau du signal acoustique en sortie aux fiches de sorties symétrique et asymétrique, à l’arrière du rack. On obtient un niveau de référence lorsque le bouton est en position maximale (vers la droite).

3 : Afficheur de niveau audio - Cet afficheur (similaire aux Bargraphs utilisés sur les équipements audio) indique le niveau du signal d’entrée audio. Lorsque le segment“0”est allumé, le niveau du signal d’entrée est optimisé à gain unitaire ; lorsque le segment“+6”est allumé, le signal sature. Lorsque seul le segment de gauche“-20”est allumé, le niveau du signal d’entrée n’est qu’à 10 % de son niveau optimal. Si aucun segment n’est allumé, quasiment aucun signal n’est reçu. Pour plus d’information, voir la page 30 de ce manuel.
