Introduction / System Features

We know you don’t like reading owners manuals, but you’ve just purchased one of the most unique wireless systems around, and we want to tell you about it! So, before you plug in and start using it, we’d like to suggest you take just a few moments out to scan these pages. We’ll make it as painless as possible, we promise—and, who knows, you might just pick up a tip or two.

Every wireless system consists of at least two components—a transmitter and a receiver, both of which must be tuned to the same channel (that is, the same radio frequency) in order to operate correctly.* The Samson Synth 32 system is

frequency-agile; that is, it is capable of operating over any of a number of selectable frequencies, making it eminently suitable for touring setups or where multiple wireless systems need to be used simultaneously. Specifically, it offers 32 different operating frequencies within each of three bands (low, medium, or high), allowing up to six different Synth 32 systems to be used simultaneously in one band. The system you have purchased contains an R32 receiver and either our T32 belt-pack transmitter (for instrument or lavalier microphone or headset applications) or H32 hand-held microphone transmitter (available in a wide variety of popular capsules).

In this manual, you’ll find a QuickStart section (for those of you familiar with wireless audio systems) as well as more detailed description of the features of the Synth 32 system, a guided tour through all components, step-by-step instructions for setting up your system, wiring diagrams and tables, a channel plan and full specifications. If your Synth 32 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 Synth 32 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 Synth 32 system ever require servicing, a

Return Authorization number (RA) is necessary. Without this number, the unit will not be accepted. If your Synth 32 system was purchased in the United States, please call Samson at 1-800-372-6766 for a Return Authorization number prior to shipping your unit. If possible, return the unit in its original carton and packing materials. If your Synth 32 system was purchased outside of the U. S., contact your local distributor for servicing information.

* Your receiver and transmitter have been factory preset to utilize the same channel. A listing of the available channels and their corresponding UHF frequencies is presented in Appendix B on page 54 in this manual.

System Features

Designed for use in both live sound and sound contracting applications, the Samson UHF Synth 32 Wireless System provides a high performance, cost effective solution, utilizing state-of-the-art technology in wireless communications. Its main features include:

•Three bands of operation (low, medium and high), with 32 different available channels per band, all operating in the less crowded UHF bandwidth. Up to six Synth 32 systems (each tuned to a different frequency within the same band) can be used in the same location without interference. (U.S. users, who can access both the low and medium bands, have access to 64 channels and can use up to twelve Synth 32 systems in a single location.)

ENGLISH

System Features

•Technological breakthrough usage of SAW (Surface Acoustic Wave) filters (similar to those used in high-end television receivers) for extremely precise and stable tuning.

•True Diversity technology maximizes active range (up to 300 feet) and reduces potential interference problems through automatic switching between two independent receivers.

•The R32 receiver is a half-rack unit that can be used freestanding or can be mounted in any standard 19" rack,* making it easy to integrate into any traveling or fixed installation audio system. It includes a pair of tuned antennas and provides both balanced and unbalanced outputs, line/mic output level switch, continuously adjustable Volume and Mute (noise squelch) controls, and a backlit LCD display containing band/group/channel information, dual receiver indicators and RF and AF level strength meters.

•Built-in companding noise reduction in all components for crystal-clear sound with minimized background noise and hiss.

•Transmitters utilize PLL synthesized VCO technology to minimize spurious emissions and provide “popless” muting, which turns off the audio signal while leaving the carrier signal on. They use standard 9-volt batteries, with battery life of approximately 8 hours. Transmitters also provide a convenient three-segment multicolor Battery Strength LED meter, allowing you to monitor the remaining power in the installed battery.

•Compact “beeper-sized” T32 belt-pack transmitter is extremely lightweight (less than 4 ounces with a 9-volt battery installed). It provides a mini-XLR jack for connection to guitar cables or a variety of popular headsets and lavalier microphones, including:

Samson QE headset** Samson QV headset

AKG C-410 headset Audio-Technica ATM-75 headset Audio-Technica MT-350 lavalier Audio-Technica

QuickStart

If you’ve had some prior experience using wireless systems, these QuickStart instructions will get you up and running with your Synth 32 system in a matter of minutes! Detailed instructions for setting up and using your Synth 32 can be found on page 11 of this manual, and the “Guided Tour” sections on pages 4 - 10 provide full descriptions of all Synth 32 controls and displays.

1. Make sure that the supplied R32 receiver and T32 or H32 transmitter are factory preset to the same band (High, Medium or Low).

2. Physically place the R32 where it will be used and extend both antennas vertically.

3. If you are using the T32 with a lavalier or headset microphone, make the physical connection between its mini-XLR input connector and the microphone you are using.

4. Place a fresh battery in the transmitter and turn it on momentarily to check it; the transmitter’s multifunction LED will light green if the battery is sufficiently strong.

5. Turn your audio system off and make the physical cable connection between the R32 balanced or unbalanced output jack (if necessary, both can be used simultaneously) and the line or mic level audio input of your amplifier or mixer. If you are using the balanced output jack, be sure to set the R32 rear panel Audio Output Level switch correctly.

6. With the audio system still off, connect the supplied AC adapter to the DC Input on the rear panel of the R32 (first looping the cable around the strain relief), then plug it in and turn it on by pressing its Power switch; the front-panel LCD will light up.

7. Determine the best Group and Channel to use by turning the transmitter off and pressing the R32 front-panel Frequency/Group increment/decrement buttons, observing the RF Level display as you do so. If any segments light (with the transmitter off), the selected Channel may be receiving interference and is probably unsuitable for use. Select a Group that has the greatest number of suitable Channels (that is, Channels where no segments light with the transmitter off), then select a quiet Channel within that Group. Remember that, when two or more transmitters and receivers are being used at the same location, all devices must be set to the same Group.

8. Turn on the transmitter and use the supplied plastic screwdriver to set it to the same Group and Channel (the mulifunction LED on the T32 or H32 will blink whenever you select a Channel that is unavailable within the currently selected Group).

9. Do a walkaround through the intended area of coverage while observing the R32’s RF Level display. Reposition or select a different Group/Channel as necessary.

10. Set the audio gain structure by speaking or singing into your mic (or playing your instrument) at a normal performance level while using the supplied plastic screwdriver to turn the transmitter’s AF Level trimpot slowly clockwise until the second from right segment on the R32 AF Level meter lights frequently (this segment corresponds roughly to 0 vu).

11. Turn on your audio system and set it to a low listening level. While continuing to sing, speak or play at a normal performance level, slowly turn the R32 Volume knob fully clockwise; this is unity gain. Then slowly raise the volume of your amplifier and/or mixer to the desired listening level.

12. If you hear any spurious noise from the R32 output when the transmitter is turned off, use the supplied plastic screwdriver to adjust the R32 Mute (noise squelch) control, slowly turning it clockwise until the point at which the noise disappears.

ENGLISH

Guided Tour - R32 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 R32. See the “Setting Up and Using the Synth 32 System” section on page 11 in this manual for more information about antenna positioning.

2: Display section - This backlit Liquid Crystal Display (LCD) shows you information about the current status of the R32 (see below for details).

2a: Receiver Antenna indicator - When signal is being received, one of these will be displayed, showing you whether the “A” or “B” antenna is currently being used. A computer chip inside the R32 constantly scans the two 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.

2b: Band indicator - Shows whether the Low (“L”), Medium (“M”) or High (“H”) band is being used. This is factory preset and cannot be adjusted by the user.

2c: Group/Channel indicator - Shows the currently selected Group and Channel. When two or more transmitters and receivers are being used in the same location, they should be set up to use different Channels within the same Group.

2d: RF (Radio Frequency) Level meter - This six-segment “ladder” meter (similar to the VU bar meter used on audio devices) indicates the strength of the UHF signal being received. When all segments are lit, the incoming RF signal is at optimum strength; when only the left-most segment is lit, the incoming RF signal is at minimum strength. If no segments are lit, no signal is being received; check to ensure that the transmitter is on and that it is set to the same Group and Channel as the receiver. See the “Setting Up and Using the Synth 32 System” section on page 11 in this manual for more information.

2e: AF (Audio Frequency) Level meter - This six-segment “ladder” meter (similar to the VU bar meter used on audio devices) indicates the presence of audio signal. When all segments are lit, the outgoing audio signal is at maximum strength; when only the left-most segment is lit, the outgoing signal is at minimum strength.

2f: Mute indicator - Lights to indicate that the R32 is muted (no sound output), either because the transmitter has been turned off or because of poor signal reception (due to weak signal, excess modulation noise, or because signal is being received from another manufacturer’s equipment). Note that it takes about half a second before the Mute indicator turns on or off after a transmitter is muted or unmuted.

3: Frequency / Group increment/decrement buttons - Use these to select the Group and Channel you wish to use. The “up” button increases the setting by one, while the “down” button decreases the setting by one. Hold down the button for fast adjustments. Only available Channels within each group are shown (see Appendix B: Channel Plan on page 54 in this manual for a complete listing). See the “Setting Up and Using the Synth 32 System” section on page 11 in this manual for more information.

4: Mute (noise squelch) control - This control determines the maximum range of the R32 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 Synth 32 System” section on page 11 in this manual for more information.

5: 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. Reference level is obtained when the knob is turned fully clockwise (to its “10” setting).

6: Power switch - Use this to turn the R32 power on and off. When the receiver is on, the backlit LCD display (see #2 above) is lit.

Guided Tour - R32 Rear Panel

1: DC input - Connect the supplied 12 volt 220 mA 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 R32 and will void your warranty.

2: Unbalanced output* - Use this unbalanced high impedance (5K Ohm) 1/4" jack when connecting the R32 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 the “Setting Up and Using the Synth 32 System” section on page 12 in this manual for more information.

4: Balanced output* - Use this electronically balanced low impedance (600 Ohm) XLR jack when connecting the R32 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.

Using the strain relief: Gather up a loop of wire and pass it through the strain relief,

then pass the adapter plug through the loop in order to create a knot.

1: Antenna - This permanently attached transmitter “pig tail” antenna should be fully extended for normal operations. See the “Setting Up and Using the Synth 32 System” section on page 11 in this manual for more information about antenna positioning.

2: Multifunction LED - This multicolor LED serves several functions. First, it lights whenever the T32 is powered on (see #7 on the next page). Secondly, whenever the T32 is powered on, it shows the relative battery power, indicating whether the installed battery is at low (red), mid (orange) or high (green) strength. When it lights steadily red (“low”), RF performance is degraded and the battery needs to be replaced. Finally, the LED blinks whenever an unavailable Channel within a Group is selected. See #5 on the following page for more information and Appendix B on page 54 in this manual for a complete channel plan.

3: Input connector - The input device (instrument cable, lavalier mic, or headset mic) is connected to this mini-XLR jack. See Appendix A on page 53 for more information.

See the “Setting Up and Using the Synth 32 System” section on page 11 in this manual for more information.

11: Audio on-off switch - When set to the “on” position, audio signal is transmitted. When set to the “off” position, the audio signal is muted. 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 transmitter for extended periods, turn off the transmitter power by using the power on-off switch (see #7 above).

* Be sure to mute the audio signal at your external mixer or amplifier before turning transmitter power on or off, or an audible pop may result.

TRANSMITTER MODEL H32

Setting Up and Using the

Synth 32 System

The basic procedure for setting up and using your Synth 32 Wireless System takes only a few minutes:

1. For the Synth 32 system to work correctly, both the receiver and transmitter must be set to the same band (labeled “Low,” “Medium” and “High”). Remove all packing materials (save them in case of need for future service) and check to make sure that the supplied R32 receiver and T32 or H32 transmitter are factory preset to the same band. If these do not match, contact your distributor or, if purchased in the United States, call Samson Technical Support at 1-800-372-6766.

2. Physically place the R32 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). An optional rack-mount kit (available from your Samson dealer) allows the R32 to be mounted in a standard 19" rack if desired. Place both the “A” and “B” antennas in their vertical position.

3. If you are using the T32 beltpack transmitter with a permanently attached instrument cable, skip ahead to step 4a below. If you are using the T32 with a lavalier or headset microphone, make the physical connection between its mini-XLR input connector and the microphone you are using. Because the mini-XLR plug is “keyed,” you’ll need to rotate it a certain way to get it to “mate” with the connector mounted on the T32; then push straight down until you hear a click. To remove the mini-XLR connector, press in the black dot on the plug and pull straight out (do not use force!). We recommend that you never pull on the wire, only the plug itself (with the black dot pressed in). If you are using a lavalier microphone, correct placement is critical to sound quality. We recommend that you position it as shown in the illustration on the right—as close to your mouth as possible but off to one side (to minimize nasality) and unobstructed by clothing. Bear in mind also that omnidirectional microphones (mics which pick up signal from all directions) are more prone to feedback problems than

unidirectional (cardioid or supercar-

dioid) ones; in general, you can avoid feedback by

taking care not to use any microphone directly in front of a PA speaker (if this is unavoidable, you can try using an equalizer to attenuate those high frequencies which are causing the feedback “squealing”).

4a. If your system contains a T32 belt-pack transmitter, make sure its pigtail antenna is extended fully and then press gently inwards on the two tabs marked “Open” (on the sides of the case) to open the battery door, which is hinged and not intended to be removed from the transmitter case. Please use care when opening this door as undue force will destroy the hinge.

4b. If your system contains a H32 handheld transmitter, unscrew the bottom section of the microphone by turning it counterclockwise and then slide it off.

ENGLISH

INPUT

SAMSON

Setting Up and Using the Synth 32 System

5. Place a fresh 9-volt alkaline battery in the transmitter battery holder, taking care to observe the polarity markings. If you are using a T32 belt-pack transmitter, gently replace the battery door by swinging it up and pressing until it clicks. If you are using a H32 handheld transmitter, replace the bottom section of the microphone by sliding it on and then screwing it back on. Whichever transmitter you are using, leave it off for the moment.

6. To check the battery strength, turn on the power to the T32 or H32 transmitter (using its Power on-off switch). The multifunction LED will light green if the battery is sufficiently strong. Once you’ve established that the installed battery has sufficient power, use the Power on-off switch to turn the transmitter off again.

7. Make the physical cable connection between the R32 output jack and the line or mic level audio input of your amplifier or mixer. If you are using the balanced XLR jack (preferable, since it will deliver an electromagnetically cleaner signal), be sure to set the R32 rear panel Audio Output Level switch correctly. When connecting the R32 balanced output to a mic input of a mixer or amplifier, this switch should be set to the left (“-40dBm”) position. If required, both the balanced and unbalanced outputs can be used simultaneously. Leave your amplifier (and/or mixer) off at this time.

8. Turn the Volume knob on the R32 completely counterclockwise. Using the strain relief, connect the supplied AC adapter to the DC Input on the rear panel of the R32, then plug the adapter into any standard AC outlet. Press the front panel Power switch to turn on the R32; the backlit LCD will light up.

9. Next, select the Group and Channel for your transmitters and receivers. When two or more transmitters and receivers are being used at the same location,

all devices must be

set to the same Group

(though each transmitter/receiver pair must use its own Channel) or intermodulation noise may occur. Make sure the power to the T32 or H32 transmitter is off and use the Frequency / Group increment/decrement buttons on the front panel of the R32 to step through all the available Groups and Channels, observing the RF Level display as you do so. If any segments light (with the transmitter off), the selected Channel may be receiving interference and is probably unsuitable for use (one segment lighting is insignificant). Select a Group that has the greatest number of suitable Channels (that is, Channels where no segments light with the transmitter off). See Appendix B on page 54 in this manual for more information. When you have decided which Group and Channel you wish to utilize, turn on the T32 or H32 transmitter (using its Power On-Off switch) and use the supplied plastic screwdriver to set it to the same Group and Channel (the multifunction LED on the T32 or H32 will blink whenever you select a Channel that is unavailable within the currently selected Group). At this point, either the “A” or “B” indicator in the R32 LCD display will appear (depending upon which antenna is receiving the stronger signal).

10. When first setting up the Synth 32 System in a new environment, it’s always a good idea to do a walkaround while experimenting with different Group and Channel settings and observing the R32’s RF Level display—you may find that some cause more segments to appear than others (the more segments appear, the stronger the signal—if all five segments appear, the R32 is receiving an optimally strong RF signal and is placed and positioned correctly). Always pick the Group that has the greatest number of clear Channels and the Channel providing the strongest signal. The basic rule of thumb for

ENGLISH

Setting Up and Using the

Synth 32 System

successful wireless installations is to always try to minimize the distance between transmitter and receiver as much as possible and also to try to maintain “line of sight” between the two (so that the person using the transmitter can see the receiver antennas). You may also be able to improve RF reception by relocating the receiver or repositioning one or both of the receiver antennas.

11. Once you’ve settled on your Group and Channel assignments, it’s time to set the audio gain structure. If you are using a H32 transmitter or T32 transmitter with a connected lavalier or headset microphone, make sure it is unmuted (the Mute indicator in the R32 LCD display should not be lit). Then speak or sing into the mic at a normal performance level while using the supplied plastic screwdriver to turn the AF Level control (trimpot) on the transmitter slowly clockwise until the second from right segment on the AF Level meter of the receiver appears most of the time. If you are using the T32 transmitter with a connected instrument, play the instrument at normal performance level while using the supplied plastic screwdriver to turn the AF Level control (trimpot) on the transmitter slowly clockwise until the second from right segment on the AF Level meter of the receiver lights most of the time. This segment corresponds roughly to 0 vu.

12. Turn on your connected amplifier and/or mixer and set it to a low listening level. While continuing to sing or speak into the mic at normal performance level (or while continuing to play an instrument connected to the T32 at normal performance level), slowly turn the receiver Volume knob fully clockwise; this is unity gain. Finally, slowly raise the volume of your amplifier and/or mixer to normal listening level.

13. Temporarily turn down the level of your mixer/amplifier system and turn off the power to your transmitter, leaving the R32 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 R32 front panel Mute (noise squelch) control. When the Mute control is at its minimum setting, the Synth 32 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 transmitter is turned off. To do so, use the provided screwdriver to rotate the Mute 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).

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 / Fonctions du système

Nous savons que vous n’aimez pas vous plonger dans la lecture des modes d’emploi, mais vous venez d’acheter l’un des systèmes sans fil les plus incroyables qui existent et nous souhaitons vous le présenter. Donc, avant de vous lancer dans l’utilisation de votre sans fil, nous vous suggérons de prendre quelques instants pour parcourir ces quelques pages. Vous verrez, cela demande peu d’effort et vous y gagnerez une utilisation efficace de votre produit et sans doute quelques astuces complémentaires.

Tous les systèmes sans fil se composent au moins d’un émetteur et d’un récepteur. Pour fonctionner correctement, ils doivent tous deux être réglés sur le même canal (c’est-à-dire, la même fréquence radio)*. Le système Synth 32 Samson est multifréquence : il est capable de fonctionner sur différentes fréquences sélectionnables. Il convient donc parfaitement aux configurations de tournée ou aux configurations impliquant l’utilisation simultanée de plusieurs systèmes sans fil. Il offre plus précisément 32 fréquences différentes dans chacune des trois bandes (basse, intermédiaire, haute), permettant l’utilisation simultanée de six systèmes Synth 32 différents sur la même bande de fréquences. Le système que vous venez d’acheter comprend un récepteur R32 et, au choix, notre émetteur de poche T32 (pour les instruments, les micros-cravates ou les applications sur serre-tête) ou l’émetteur à main H32 (disponible avec de nombreuses capsules de qualité).

Ce mode d’emploi se compose d’un Guide d’utilisation rapide (pour ceux d’entre vous qui connaissent déjà les arcanes des systèmes sans fil) ainsi que d’une description plus détaillées des fonctions du système Synth 32, une présentation de tous ses composants, des instructions précises pour la configuration de votre système, des schémas et des tableaux illustrant les connexions, un tableau des canaux et des caractéristiques techniques complètes. Si vous avez acheté votre système Synth 32 aux Etats-Unis, vous y trouverez une carte de garantie : n’oubliez pas de la remplir et de la renvoyer ! Cela vous permettra de recevoir une assistance technique en ligne, ainsi que les mises à jour de votre produit et des informations concernant les autres produits de la gamme Samson.

Fonctions du système

pouvez utiliser jusqu’à six systèmes Synth 32 (chacun étant réglé sur une fréquence différente de la même bande) dans le même lieu sans interférence.

•Une utilisation à la pointe de la technologie des filtres SAW (Surface Acoustic Wave ; similaires à ceux utilisés sur les récepteurs télévision de haute qualité) pour un accordage extrêmement stable et précis.

•La technologie True Diversity permet de maximiser la portée (jusqu’à 100 mètres) et de réduire les problèmes potentiels d’interférences grâce à la commutation automatique entre deux récepteurs indépendants.

•Le récepteur R32 est au format demi rack 1U et peut être utilisé seul ou monté en rack standard 19"*. Cette polyvalence permet une intégration facile à tout système audio en installation fixe ou mobile. Ce récepteur comprend deux antennes accordées et il est équipé de sorties symétrique et asymétrique, d’un sélecteur de niveau de sortie ligne/micro, de réglages Volume et Mute (circuit Squelch anti-bruit) et d’un écran LCD affichant des informations de bande/groupe/canal, des témoins du double récepteur et des afficheurs de niveau HF et AF (audio).

•Une suppression de bruit intégrée par compandeur au niveau de tous les composants pour un son extrêmement clair (bruit de fond et souffle minimisés au maximum)

•Les émetteurs utilisent la technologie VCO à synthétiseur PLL pour optimiser le rejet des fréquences parasites et offrir une fonction Mute sans « pop » de coupure du signal audio mais avec conservation de la porteuse. Ils fonctionnent sur pile 9 Volts standard qui leur confèrent une autonomie d’environ 8 heures. Ces émetteurs sont également équipés d’un afficheur multicolore 3 segments à LED indiquant le niveau de la pile et vous permettant de contrôler aisément l’alimentation.

•L’émetteur de poche compact T32 est extrêmement léger (moins de 120 grammes avec pile 9 Volts installée). Il est équipé d’un connecteur mini XLR pour la connexion des câbles guitare ou d’une gamme de microphones sur serre-tête ou de micro-cravate, dont les modèles suivants :

Émetteur sur serre-tête Samson QE ** Émetteur sur serre-tête Samson QV

Émetteur sur serre-tête AKG C-410 Émetteur sur serre-tête Audio-Technica ATM-75

Guide d’utilisation rapide

Si vous avez déjà acquis une certaine expérience en matière d’utilisation des systèmes sans fil, ces instructions d’utilisation rapide vont vous permettre d’utiliser votre système Synth 32 en un rien de temps ! vous trouverez des instructions détaillées sur la configuration et l’utilisation de votre système Synth 32 en page 24 de ce mode d’emploi. De plus, la “Présentation” aux pages 17 - 23 propose une description complète des affichages et des réglages du système Synth 32.

1. Assurez-vous que le récepteur R32 fourni et que l’émetteur T32 ou H32 sont préprogrammés en usine sur la même bande de fréquences (haute, intermédiaire ou basse).

2. Placez le R32 dans le lieu où il doit être utilisé et étirez verticalement les deux antennes.

3. Si vous utilisez le T32 avec un micro-cravate ou un micro sur serre-tête, reliez le connecteur microphone que vous utilisez à l’entrée mini XLR.

4. Placez une pile neuve dans l’émetteur et activez-le momentanément pour vérifier son fonctionnement. La LED multifonction de l’émetteur s’allume en vert si la pile est suffisamment chargée.

5. Coupez votre système audio et effectuez la connexion du câble entre le connecteur de sortie symétrique ou asymétrique du R32 (les deux peuvent être utilisées simultanément si nécessaire) et l’entrée à niveau ligne ou à niveau micro de votre amplificateur ou de votre mélangeur. Si vous utilisez la sortie symétrique, assurez-vous de placez correctement le sélecteur de niveau de sortie audio situé en face arrière du R32.

6. Le système audio est toujours désactivé, connectez l’adaptateur secteur fourni à l’embase DC en face arrière du R32 (en prenant d’abord soin de faire un tour dans le passe-câble), puis reliez-le au secteur appuyez sur l’interrupteur Power. L’écran LCD s’allume en façade.

7. Déterminez le meilleur groupe et le meilleur canal à utiliser en désactivant l’émetteur et en appuyant sur les touches d’incrémentation/décrémentation Frequency/Group en face avant du R32. Observez en même temps l’affichage du niveau HF. Si les segments s’allument (alors que l’émetteur est désactivé), le canal sélectionné reçoit sans doute des interférences, il est donc inutilisable. Sélectionnez le groupe présentant le plus grand nombre de canaux utilisables (c’est-à-dire des canaux pour lesquels aucun segment ne s’allume lorsque l’émetteur est désactivé), puis choisissez un canal avec le moins d’interférences au sein de ce groupe. Souvenez-vous que lorsque deux ou plusieurs émetteurs et récepteurs sont utilisés dans un même lieu, tous les appareils doivent utiliser le même groupe.

8. Activez l’émetteur et utilisez le tournevis en plastique fourni pour le régler sur le même groupe et le même canal (la LED multifonction du T32 ou du H32 clignote lorsque vous sélectionnez un canal non disponible dans le groupe actuellement sélectionné).

9. Déplacez-vous dans la zone de portée souhaitée, tout en observant le niveau HF sur le R32. Repositionnez-vous ou sélectionnez un autre groupe/canal si nécessaire.

10. Réglez le gain audio en parlant ou en chantant dans votre microphone (ou en jouant de votre instrument) à un niveau normal tout en utilisant le tournevis en plastique fourni pour tourner lentement vers la droite l’atténuateur de niveau audio (AF) de l’émetteur jusqu’à ce que le second segment en partant de la droite de l’afficheur de niveau audio du R32 s’allume fréquemment (ce segment correspond environ à 0 VU).

11. Activez votre système audio et utilisez un faible niveau d’écoute. En continuant à chanter, parler ou jouer à un niveau normal, tournez lentement le potentiomètre de volume du R32 au maximum vers la droite (position de gain unitaire). Augmentez ensuite doucement le volume de votre amplificateur et/ou mélangeur pour atteindre le niveau désiré.

12. Si vous entendez des bruits parasites en sortie du R32 lorsque l’émetteur est désactivé, réglez la fonction Mute du R32 (circuit Squelch anti-bruit) à l’aide du tournevis en plastique fourni. Tournez-le doucement vers la droite jusqu’au point de disparition du bruit.
