This device complies with the European R&TTE Directive.
Operation is subject to the condition that this device does not cause harmful
interference.
CAUTION! Electrical shock can result from removal of the receiver cover. Refer
servicing to qualified 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 european regulations (R & TTE
directive). 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 0.035 watts output for T310 and 0.01 watts for T314 and T371) 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.
CAUTION! Do not expose batteries to excessive heat, such as direct sunlight
or open fires.
Thank you for choosing an Audio-Technica professional wireless system. You have
joined thousands of other satisfied customers who have chosen our products because
of their quality, performance and reliability. This Audio-Technica wireless microphone
system is the successful result of years of design and manufacturing experience.
• Band F 840.125 - 864.875 (TV Channels 67 - 69)
• Band E 795.500 - 820.000 (TV Channels 61 - 64)
For simplicity, model numbers used throughout the manual will reference only the basic
model number without reference to band indications.
Each wireless system includes a receiver and either a body-pack or handheld
transmitter. Individual components are also available separately.
All 3000 Series components feature soft-touch controls for quick, easy access to a
formidable range of functions; an LCD information display in each unit provides
convenient visual indication of unit settings and operation.
The ATW-R3100 receiver is equipped with automatic frequency scanning for easy set-
up. It also features true diversity reception. Two antennas feed two completely
independent RF sections on the same frequency; automatic logic circuitry continuously
compares and selects the superior received signal, providing better sound quality and
reducing the possibility of interference and dropouts. Soft-touch controls provide
convenient access to a variety of functions, while an LCD information display provides
constant monitoring of system operation, including indication of the transmitter's
battery status. The receiver is half-width for a standard 1U 19" rack mount; rack-mount
adapters are included. Two receivers can be mounted side by side, using an optional
.

functions, the transmitter features a three-position sliding cover to limit access, if
desired, to just the Power/Mute button, or to no controls, as appropriate for the
application and user.
The ATW-T341 handheld dynamic microphone/transmitter features the same element
used in the Artist Elite® AE4100 dynamic handheld microphone created for professional
live-sound venues.
The ATW-T371 handheld condenser microphone/transmitter features the same element
used in the Artist Series ATM710 cardioid condenser vocal microphone
Transmitters in the 3000 Series use two 1.5V AA batteries for economical operation and
wide availability. The receiver and both transmitters have "fuel gauge" battery condition
indicators with low-battery warnings.
An advanced Digital Tone Lock™ tone squelch system in the ATW-R3100 receiver opens
only when a 3000 Series transmitter is detected, reducing the possibility of interference.
As a result, 3000 Series transmitters and receivers must be used together and should
not be used with components from other Audio-Technica wireless systems, or with
those of other manufacturers.
Please note that in multiple-system applications there must be a transmitter-receiver
combination set to a separate frequency for each input desired (only one transmitter for
each receiver).
Because the wireless frequencies are within UHF TV frequency bands, only certain
operating frequencies may be useable in a particular geographic area. System
operating frequencies will be found on page 14 onwards.

Receiver Installation

Location
For best operation the receiver should be at least 3 ft. (1 m) above the ground and at
least 3 ft. away from a wall or metal surface to minimize reflections. The transmitter
should be at least 3 ft. from the receiver, as shown in Figure A. Keep antennas away
from noise sources such as digital equipment, motors, automobiles and neon lights, as
well as away from large metal objects.
Output Connections
There are two audio outputs on the back panel: balanced (32 mV) and unbalanced (50
mV). 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 housing 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
panel to the mixer. The two isolated audio outputs permit simultaneous feeds to both
unbalanced and balanced inputs. For example, both a guitar amp and a mixer can be
driven by the receiver.
Antennas
Attach the included pair of UHF antennas to the antenna input jacks. The antennas are
normally positioned in the shape of a "V" (both 45° from vertical) for best reception.
Antennas can be remotely located from the receiver. However, due to signal loss in
cables at UHF frequencies, use the lowest-loss RF cables practical for any cable runs
over 25 feet. RG8-type is a good choice. Use only copper-shielded cable, not CATV-type
foil-shielded wire. Audio-Technica offers quality RF cables in four lengths, as well as
remote antennas; see the Optional System Accessories section on page 13.
Power Connections
Connect the included PS6 13.5V, 500mA AC adapter to the DC power input on the back
of the receiver. Loop the small cord from the DC plug over the cord hook above the jack,
to keep the plug from being detached by an accidental tug on the cord. Then plug the
larger cord from the in-line adapter into a standard 230 Volt 50 Hz AC power outlet.
Operation of the receiver is controlled by the front-panel Power switch.
(Note: Units supplied to countries with 120V mains should include an in-line AC adapter
appropriate for that country.)
