This device complies with Industry Canada licence-exempt RSS standard(s). Operation is
Subject to the following two conditions: (1) this device may not cause interference, and (2)
this device must accept any interference, including interference that may cause undesired
operation of the device.
CAUTION! Electrical shock can result from removal of the receiver cover. Refer servicing
to qualied service personnel. No user-serviceable parts inside. Do not expose to rain or
moisture.
The circuits inside the receiver and transmitter have been precisely adjusted for optimum
performance and compliance with federal regulations. Do not attempt to open the receiver or
transmitter. 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 difculty, 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 congurations, the ATR7000 Series Wireless Systems
are single-channel, xed-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.
Both the handheld and body-pack transmitters offer an easily accessible On/Off/Standby switch;
the body-pack also features an external microphone volume control and a convenient 3.5 mm
locking input.

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 reections. 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/amplier’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-Pack Transmitter 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 modication 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.

System Operation
Turn down the receiver volume control and the mixer/amplier 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 amplier
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.
