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.

Installation and Operation

Audio-Technica’s ATR7000 Series Wireless Systems are compact, portable, versatile systems designed to provide reliable performance, easy setup and clear, natural sound quality. Available in handheld, headworn, guitar, and lavalier configurations, the ATR7000 Series Wireless Systems are single-channel, fixed-frequency systems available in three VHF frequencies (169.505, 170.245, and 171.905 MHz).

Each ATR7000 Series Wireless System includes the ATR-R7000 receiver and either a body-pack transmitter or handheld microphone/transmitter. The ATR-R7000 is a non-diversity, singlechannel receiver with a quarter-wave telescoping antenna for extended operating range of up to 200 feet. The ATR-R7000 receiver also offers volume control along with Power, RF and AF Peak indicator lights. It can be placed horizontally or vertically with the included stand mount.

Because ATR7000 Series packaging is designed to hold all versions of the system, some compartments in the carton are intentionally left empty.

The ATR-R7000 receiver includes a space-saving, switching power supply that automatically adapts to changes in mains voltage. Unlike bulky linear power supplies, this switching power supply is lightweight and compact; it uses only a single outlet space.

The ATR7100 Systems body-pack transmitters are designed to work with the lavalier, or the headworn microphone or guitar cable included in the wireless system you selected. The ATR7200 Systems handheld transmitter features a unidirectional dynamic microphone element.

Both the body-pack and handheld transmitters use internal 9-volt batteries and have Off/Standby/ On switches. The body-pack transmitter also offers a volume control.

Receiver Installation

Location

For best operation the receiver should be at least 3' (1 m) above the ground and at least 3'

(1 m) away from a wall or metal surface to minimize reflections. Keep the receiver antenna away from noise sources such as digital equipment, motors, automobiles and neon lights, as well

as large metal objects. In multi-channel systems, position receivers at least 3' (1 m) apart and keep operating transmitters at least 6' (2 m) from the receivers to help assure maximum RF performance.

Output Connection

The receiver provides unbalanced, aux-level output from a ¼" TS (“mono”) phone jack; an output cable is included. Use this shielded audio cable with ¼" phone plug to connect the receiver’s Audio Out jack to the mixer/amplifier’s aux-level input.

Power Connection

Connect the DC plug on the included AC power adapter to the DC power input on the back of the receiver. Then plug the adapter into a standard 120 Volt 60 Hz AC power outlet.

Antennas

The receiver is equipped with a quarter-wave telescoping antenna for extended operating range of up to 200 feet. The quarter-wave telescoping antenna offers extended operating range of up to 200 feet. Position the fully extended antenna in a vertical position for best operating performance.

Be certain to extend the antenna to its full 15" (39 cm) length by holding it at its base and pulling out on its cap. The antenna may be swiveled 180° in a single plate to achieve vertical position depending upon position of the receiver, but do not attempt to rotate it in a screwing/ unscrewing motion. To do so may damage the antenna and/or receiver. For best performance, locate the receiver so its antenna is in direct line-of-sight to the transmitter's likely operating position.

Mounting Instructions

The receiver features versatile positioning for horizontal or vertical applications. For a horizontal application, place the receiver on a horizontal surface (rubber feet on bottom).

For a vertical mounting position, use the included stand mount. The stand mount snaps into receptacles on the right side of the receiver. Simply insert the stand mount pegs into the receptacles and slide gently into place until locked. Reverse the motion to remove the stand mount.

Transmitter Setup Controls and Functions

Battery Selection and Installation

An alkaline 9-volt battery is recommended. Make certain the transmitter power switch is Off before installing or changing batteries. When inserting the battery, observe correct polarity as marked inside the battery compartment. The transmitter housings are designed to prevent incorrect installation of the battery; do not force the battery in. Reversed batteries may cause damage to the transmitter.

2.Carefully insert a fresh 9V alkaline battery, observing polarity markings.

3.Screw the body back together. Do not overtighten.

Battery Condition Indicator

The red battery condition indicator (Fig. D/E) should light strongly with a fresh battery. As the battery weakens, the indicator will grow dimmer. When the indicator becomes very dim or goes out, there is little life left in the battery. Replace it at once for continued operation of the transmitter.

Body-PackTransmitter Input Connection

Connect an audio input device (included lavalier microphone, guitar cable or headworn microphone) to the input connector on the top of the transmitter. This is a screw-down locking connector. To lock the connector to the transmitter, screw the silver locking ring on the threaded portion of the input connector clockwise. To remove the connector, unscrew the silver locking ring counterclockwise, and then simply pull up on the connector’s metal collar.

Transmitting Antenna

The body-pack transmitter uses the attached mic/guitar cable as the antenna. Due to this feature, any modification of the cable length or connector termination will affect the

performance. If the received signal is marginal, experiment with different transmitter positions on your body or instrument or try repositioning the receiver.

ATR7000 SeriesVHFWireless Systems Installation and Operation

System Operation

Turn down the receiver volume control 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. Turn on the rotary On/Off/Volume control. The red power indicator on the front panel will light.

Transmitter on...

When the transmitter is switched on, the receiver’s green RF signal indicator will light. The transmitters have a 3-position power switch. When the switch is set to “Standby” (ST or ST.BY), the transmitter produces RF with no audio signal. When the switch is “On,” the transmitter produces both RF and audio. Excessive audio input to the transmitter will cause the receiver’s red AF Peak indicator to light.

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

Ten Tips to Obtain the Best Results

1.Use only fresh alkaline batteries. Do not use “general purpose” (carbon-zinc) batteries.

2.Position the receiver 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 should be as close together as conveniently possible.

4.If receiver signal is weak, try mounting it in the vertical position for improved reception.

5.Do not place the receiver antenna within 3' (1 m) of another receiver or antenna.

6.The receiver antenna should be kept away from any metal.

7.A receiver cannot receive signals from two transmitters at the same time.

8.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 of 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.

9.Turn the transmitter and receiver off when not in use. Remove the battery if the transmitter is not to be used for a period of time.

10.Make sure to screw down the locking ring on the guitar and microphone cables for a secure connection.

System Operating Frequencies

Frequency Selection

Each transmitter/receiver system operates on a single factory aligned, crystal-controlled frequency. Available frequencies are shown in the chart on page 7.

Operating frequency is specified by a two character code, such as “T2,” in addition to the actual frequency in MHz. The frequency of each transmitter appears on a label on the outside/back of the unit. The frequency of each receiver appears on a label on the bottom panel of the unit. On the body-pack the transmitter is located outside on the back. The handheld label is located inside the back of the battery compartment. The frequency of each system appears on the outer carton.

RF Interference

Please note that wireless frequencies are shared with other radio services. According to Federal Communications Commission regulations, “Wireless microphone operations are unprotected from interference from other licensed operations within the band. If any interference is received by any Government or non-Government operation, the wireless microphone must cease operation...”

If you need assistance with operation, please contact your dealer or the Audio Solutions team at Audio-Technica. Extensive wireless information is also available on the A-T Website at www.audio-technica.com.

Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
