Audio-Technica System 10 PRO Digital Wireless System

System Overview

Thank you for choosing an Audio-Technica System 10 PRO Rack-Mount digital wireless system. This system is designed to provide rock-solid performance along with easy setup and clear, natural sound quality. It features a dual-receiver chassis and remote-mount receiver unit capability, operating in the 2.4 GHz range, far from TV and DTV interference. The System 10 PRO offers extremely easy operation and instantaneous channel selection. Up to ten channels may be used together without any frequency coordination problems or group selection issues.

The System 10 wireless ensures clear communications by providing three levels of diversity assurance: frequency, time, and space. Frequency Diversity sends the signal on two dynamically allocated frequencies for interference-free communication. Time Diversity sends the signal in multiple time slots to maximize immunity to multi-path interference. Finally, Space Diversity uses two antennas on each transmitter and receiver to maximize signal integrity.

Each configuration of the System 10 PRO digital wireless system includes a rack-mountable receiver chassis with two receiver unit docks. Depending on the configuration, the system will also include one or two receiver units that may be docked in the chassis or mounted remotely, and one or two transmitters of either the handheld microphone or body-pack style (or one of each). Some configurations also include one or two lavalier mics that attach to the body-pack transmitters. Up to five chassis (10 receiver units) can be linked with the included RJ12 cable to allow for simultaneous use of all receivers and increased stability of the multi-channel system.

Because System 10 packaging is designed to hold all versions of the system, some compartments in the carton may be intentionally left empty.

The ATW-R1300 includes a switching power supply that automatically adapts to changes in mains voltage.

The versatile ATW-T1001 UniPak® body-pack transmitter has both a high-impedance input for instruments, and a low-impedance input with bias connection for use with dynamic and electret condenser microphones. The ATW-T1002 handheld transmitter features a unidirectional dynamic microphone element.

Both the body-pack and handheld transmitters use internal AA batteries and have Power/Mute switches and input Trim (level) adjustments.

Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante.

WARNING: Changes or modifications not expressly approved in writing by Audio-Technica may void the user's authority to operate this equipment.

RF Exposure Statement: This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter used in other systems. ?

The ATW-RU13 complies with FCC/IC radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines and RSS-102 of the IC radio frequency (RF) Exposure rules. This equipment has very low levels of RF energy that it deemed to comply without maximum permissive exposure evaluation. (MPE). But it is desirable that it should be installed and operated keeping the radiator at least 20cm or more away from person's body.

Le ATW-RU13 conforme aux limites d'exposition aux rayonnements énoncées pour un environnement non contrôlé et respecte les règles d'exposition aux fréquences radioélectriques (RF) CNR-102 de l'IC. Cet équipement émet une énergie RF très faible qui est considérée conforme sans évaluation de l'exposition maximale autorisée. Cependant, il est souhaitable qu'il devrait être installé et utilisé en gardant une distance de 20 cm ou plus entre le dispositif rayonnant et le corps.

The available scientific evidence does not show that any health problems are associated with using low power wireless devices. There is no proof, however, that these low power wireless devices are absolutely safe. Low power Wireless devices emit low levels of radio frequency energy (RF) in the microwave range while being used. Whereas high levels of RF can produce health effects (by heating tissue), exposure of low-level RF that does not produce heating effects cause no known adverse health effects. Many studies of low-level RF exposures have not found any biological effects. Some studies have suggested that some biological effects might occur but such findings have not been confirmed by additional research. ATW-T1001, ATW-T1002 has been tested and found to comply with FCC/IC radiation exposure limits set fourth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines and RSS-102 of the IC radio frequency (RF) Exposure rules.

Les connaissances scientifiques dont nous disposons n' ont mis en évidence aucun problème de santé associé à l' usage des appareils sans fil à faible puissance. Nous ne sommes cependant pas en mesure de prouver que ces appareils sans fil à faible puissance sont entièrement sans danger. Les appareils sans fil à faible puissance émettent une énergie radioélectrique (RF) très faible dans le spectre des micro-ondes lorsque' ils sont utilisés. Alors qu' une dose élevée de RF peut avoir des effets sur la santé (en chauffant les tissus), l' exposition à de faibles RF qui ne produisent pas de chaleur n' a pas de mauvais effets connus sur la santé. De nombreuses études ont été menées sur les expositions aux RF faibles et n' ont découvert aucun effet biologique. Certaines études ont suggéré qu' il pouvait y avoir certains effets biologiques, mais ces résultats n' ont pas été confirmés par des recherches supplémentaires. ATW-T1001, ATW-T1002 a été testé et jugé conforme aux limites d' exposition aux rayonnements énoncées pour un environnement non contrôlé et respecte les règles les radioélectriques (RF) de la FCC lignes directrices d'exposition et d' exposition aux fréquences radioélectriques (RF) CNR-102 de I' IC.

Note: The ATW-RC13 has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.

CAUTION! Electrical shock can result from removal of the receiver chassis cover. Refer servicing to qualified service personnel. No user-serviceable parts inside. Do not expose to rain or moisture. The circuits inside the chassis, receivers and transmitters have been precisely adjusted for optimum performance and compliance with federal regulations. Do not attempt to open the chassis, receivers or transmitters. To do so will void the warranty, and may cause improper operation.

Notice to individuals with implanted cardiac pacemakers or AICD devices: Any source of RF (radio frequency) energy may interfere with normal functioning of the implanted device. All wireless microphones have low-power transmitters (less than 0.05 watts output) which are unlikely to cause difficulty, especially if they are at least a few inches away. However, since a "body-pack" mic transmitter typically is placed against the body, we suggest attaching it at the belt, rather than in a shirt pocket where it may be immediately adjacent to the medical device. Note also that any medical-device disruption will cease when the RF transmitting source is turned off. Please contact your physician or medical-device provider if you have any questions, or experience any problems with the use of this or any other RF equipment.

Interference Correction: If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

This Class B digital apparatus complies with Canadian ICES-003. Cet appareil numérique de la classe B est conforme à la norme NMB-003 du Canada.

Installation

Receiver Unit Location

For best operation, position receiver unit so it is off the floor, in line of sight of transmitter and away from any large obstructions. Keep the receiver unit away from noise sources such as other digital wireless equipment, microwave ovens, as well as away from large metal objects. Keep System 10 receivers 30' (9 m) away from wireless access points.

Output Connection

The ATW-R1300 is equipped with two audio outputs for each receiver: a balanced XLR-type output and an unbalanced 1/4" TRS phone jack. Use shielded audio cable for the connection between the receiver and the mixer. If the input of the mixer is a 1/4" jack, connect a cable from the 1/4" unbalanced audio output on the back of the receiver chassis to the mixer. If the input of the mixer is an XLR-type input, connect a cable from the balanced XLR-type audio output on the back of the chassis to the mixer.

Power Connection

Connect the DC plug on the included AC power adapter to the DC power input on the back of the receiver chassis. Secure the cord over the cord hook on the chassis to keep the plug from being accidentally dislodged. Plug the adapter into a standard 120 Volt 60 Hz AC power outlet. The receiver chassis is equipped with a power On/Off switch. Turn the power off when system is not in use, and unplug the power supply if you expect not to use the system for an extended period. ?

Antennas

For best reception, position the removable antennas in the shape of a "V" so that both tilt 45°. ?

Link Connection

When using multiple systems together it is strongly recommended that you link all of the chassis (up to five) using the RJ12 cable included with each system. (Linking is not necessary if you are using only a single chassis.) Linking creates a much more stable environment in which receivers work together, with all receiving, transmitting and frequency allocation coordinated to prevent audio dropouts and enable simultaneous use of up to 10 channels. See "Linking Systems" on page 9 for more details. ?

System Operation

Turn down the volume control for both receivers and the mixer/amplifier level before starting up the wireless system. Do not switch on the transmitter yet.

Receiver on...

Plug the power supply into an AC power source, then turn on the power switch. The blue System ID Display will illuminate. ?

Transmitter on...

When the transmitter is switched on, Receiver A's green Pairing Indicator lights along with two indicators on the transmitter: the green Power/Battery/Mute status indicator and the blue System ID. The blue System ID display on the transmitter turns off after 30 seconds to conserve battery power; the transmitter Power/Battery/Mute status indicator will remain illuminated, indicating transmitter status.

To re-illuminate System ID display, press the Power/Mute switch. Note: this will alter the transmitter mute status. A slight touch of the power switch toggles between muted and unmuted operation. ?

The transmitter's Power/Battery/Mute status indicator glows red when transmitter is muted, or green to indicate unmuted status. In a low-battery situation, the Power/Battery/Mute status indicator blinks. ?

The transmitters have a soft-touch power switch. When the switch is set to "Mute" (red indicator LED), the transmitter produces RF with no audio signal. When the switch is "On" (green indicator LED) the transmitter produces both RF and audio. Excessive audio input to the transmitter will cause the receiver's Audio Indicator to light red.

Receiver Volume

Under typical operating conditions, the receiver's volume control should be turned all the way up, with overall system audio gain adjusted at the mixer or amplifier.

Input Level Adjustment

Input trimmer controls in the transmitters enable you to maximize performance for a particular microphone or guitar sensitivity, or to adjust for different acoustic input levels.

Adjusting Input Level -- UniPak® Transmitter

Slide the battery cover off the transmitter and remove the screwdriver from its clip. Using the screwdriver, gently turn the "VOL" (Volume - Microphone/Instrument Level) all the way up (clockwise, toward "H"). Check for excessive gain by speaking/singing into the microphone at typically loud levels while watching the receiver's Audio Indicator. If the Audio Indicator lights red, turn the "VOL" control slightly counterclockwise until the Audio Indicator lights green or yellow with maximum audio input to the transmitter.

Adjusting Input Level -- Handheld Transmitter

Unscrew the lower body cover and slide it off, exposing the screwdriver and "LEVEL" (Gain Trimmer) control. Remove the screwdriver from its clip. Gently turn the "LEVEL" all the way up (clockwise, toward "H"). Check for excessive gain by speaking/singing into the microphone at typically loud levels while watching the receiver's Audio Indicator. If the Audio Indicator lights red, turn the "LEVEL" control slightly counterclockwise until the Audio Indicator lights green or yellow with maximum audio input to the mic/transmitter.

Return the screwdriver to its clip and close and secure the lower body. No further transmitter gain adjustments should be needed, as long as the acoustic input does not change significantly.

CAUTION! The small trimmer controls are delicate; use only the supplied screwdriver. Do not force the trimmers beyond their normal 190° range of rotation. ?

Setting System ID Number & Pairing your Transmitter and Receiver

Your system has been preconfigured at the factory to operate with no other pairing setup required; it will work out of the box. That is, your receivers and transmitters are already digital pairs, with each transmitter sharing a System ID number with one of the receivers.

The pairing instructions outlined below will help you if you find it necessary to change system ID numbers in multiple-system configurations, or pair a new transmitter to an existing receiver.

NOTE: System ID is an identical number assigned to a paired receiver and transmitter for identification purposes. The System ID number is not related to transmitting frequency. Due to the dynamic nature of System 10's automatic frequency selection, the actual transmitting frequencies may change during power-up or performance. These frequency changes are seamless and imperceptible to the ear.

Pairing Receivers with Transmitters

Note: Up to ten transmitters may be paired with any one receiver, and up to ten channels may be used simultaneously when multiple chassis are linked. (See "Linking Systems" on page 9.)

1. Turn on the receiver chassis and transmitter.
2. Press the System ID button on the chassis that corresponds to the receiver you wish to pair. The ID number will blink on the display. Continue to press the System ID button until the display shows the number from 0 to 9 that you want.
3. Note: When pairing a receiver that is mounted out of range (typically beyond 100') of the chassis or in another room, you will need to insert another receiver unit into the pairing receiver's empty dock. Follow the directions below, then eject the substitute receiver once pairing is complete.
4. Within 15 seconds, press and hold the Pair button on the receiver chassis for about one second. The receiver's Pairing Indicator will begin to blink green. Your receiver is now in Pair Mode. ?
5. Note: If the receiver's Pair button is not pressed within 15 seconds, the System ID number will revert to its previous setting.
6. Open your transmitter and press and hold its Pair button within 30 seconds of entering Pair Mode. The transmitter display will now show the System ID number you have chosen on the receiver. The receiver's Pairing Indicator will glow steady, indicating you have successfully paired your system.
7. To pair an additional transmitter, you must switch off the first transmitter by pressing and holding its Power/Mute button. Turn the second transmitter on and follow instructions 2-4 above, making sure to assign a different System ID number to the new transmitter.
8. Repeat for each additional transmitter you wish to pair with this receiver. Remember to switch off all transmitters already paired before adding a new one and to use a unique ID number for each transmitter.
9. Note: With all transmitters turned off, the receiver's System ID Display will cycle through all currently paired ID numbers. Turn on a transmitter to activate its pairing with the receiver. The receiver recognizes only one transmitter at a time. That transmitter must be turned off before the receiver will recognize another paired transmitter. If that transmitter is turned off out of range, the receiver will not recognize another paired transmitter until the receiver is powered off and turned on again.

Linking Systems

Up to five chassis (10 receiver units) may be linked to allow the simultaneous use of up to 10 channels. If more than five chassis (10 receivers) are linked, error code E44 will flash on chassis' system ID display. Use the RJ12 cable that comes with each system to link multiple chassis. Run the RJ12 cable from the OUT connector of the first chassis to the IN connector of the second chassis. (If the IN/OUT connectors on the same chassis are linked, error code E41 will flash on chassis' system ID display.) When successfully linked, the word "LINK" will appear at the bottom of each chassis' system ID display. To extend the link, run another RJ12 cable from the OUT connector of the second chassis to the IN connector of a third. Continue in this manner to link a fourth and fifth chassis. (The IN connector of the first chassis and the OUT connector of the last chassis in the chain will remain unused.) ?

Ten Tips to Obtain the Best Results

1. Use only fresh alkaline or fully charged rechargeable batteries for the transmitter. ?
2. Position the receiver unit so that it has the fewest possible obstructions between it and the normal location of the transmitter. Line-of-sight is best.
3. The transmitter and the receiver unit should be as close together as conveniently possible, but not less than 6' (2 m).
4. While System 10 PRO has been designed to mount in a rack for convenient multi-system operation, please keep other wireless devices (including wireless systems and routers) away from System 10 PRO receivers. For best performance, some routers and Wi-Fi-based wireless systems may need to be up to 30 feet away from System 10 PRO receivers.
5. Use the included RJ12 cable to link multiple (up to five) chassis. Linking the chassis will give you a stable multi-channel system with the use of up to 10 simultaneous channels. ?
6. The receiver antennas should be kept away from any metal. ?
7. As some guitar pickups may be overly sensitive to magnetic interference, please keep the System 10 UniPak® body-pack transmitter at least 1' (0.30 m) away from guitar pickups.
8. Use the transmitter level control to optimize performance for your sound source. ?
9. If the receiver output is set too low, the overall signal-to-noise ratio of the system may be reduced. Conversely, if the volume control on the receiver is set too high, it may over-drive the input of the mixer/amplifier, causing distortion. Adjust the output level of the receiver so the highest sound pressure level going into the microphone (or the loudest instrument playing level) causes no input overload in the mixer, and yet permits the mixer level controls to operate in their "normal" range (not set too high or too low). This provides the optimum signal-to-noise for the entire system.
10. Turn off chassis and transmitters when they are not in use. During extended periods of disuse, unplug chassis and remove batteries from transmitters. ??

System Operating Frequencies

Automatic Frequency Selection

System 10 wireless systems operate in automatically selected frequencies in the 2.4 GHz range, far from TV and DTV interference. Up to ten channels may be used together without any frequency coordination problems or group selection issues. Every time a receiver/transmitter pair is powered on, it automatically selects clear frequencies. Due to the dynamic nature of System 10 automatic frequency selection, these transmitting frequencies may change during power-up or performance if interference is encountered. These frequency changes occur at both the receiver and transmitter; they are seamless and imperceptible to the ear. ?
