This Device complies with the European R & TTE Directive and conforms
with National Regulations.
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 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 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 ques-
tions, or experience any problems with the use of this or any other RF equipment.

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.
Each 2000 Series wireless system provides a choice of 10 PLL-synthesized UHF fre-
quencies. Each wireless system includes a receiver and either a body-pack or hand-
held transmitter. Individual components are also available separately.
The ATW-R2100 receiver 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 selection of operating frequency and automatic
scanning, while an LCD information display provides constant monitoring of system
operation. 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
AT8630 joining-plate kit.
The versatile ATW-T210 UniPak™ body-pack transmitter has both low- and high-
impedance inputs plus a bias connection, for use with dynamic and electret condenser
microphones, as well as Hi-Z instrument pickups.
The ATW-T220 handheld dynamic microphone/transmitter features the same element
used in the PRO 41 dynamic handheld microphone created for professional live-sound
venues.
Transmitters in the 2000 Series use two 1.5V AA batteries for economical operation and
wide availability. Both transmitters have battery condition indicators.
2000 Series receivers feature a sophisticated Tone Lock™ tone squelch system that
opens the receiver's audio output only when a 2000 Series transmitter is detected,
reducing the possibility of interference. As a result, 2000 Series transmitters and
Installation and Operation
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 channel (frequency) for each input desired (only one
transmitter for each receiver).
Because the wireless frequencies are within UHF TV frequency bands, only certain
channels (operating frequencies) may be useable in a particular geographic area. The
10 channels (operating frequencies) that are used in the 2000 Series have been select-
ed for multi-channel compatibility. Subject to frequency availability in a particular geo-
graphic area.
The operating frequencies that correspond to each of the 10 channels are listed on
page 10.

Location
See Figure A
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 (12.5 mV) and unbalanced (25
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.
Accessory 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 9.
Power Connections
Figure D-Rear Panel Controls and Functions
Connect the included 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 AD1210UK
(AD1210E Type C-4 EX Version) AC adapter into a standard 230 Volt 50 Hz AC power
outlet. For European users, plug the ADP1210E AC 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. Use the included AC adapter only with 230V 50 Hz AC
power sources)
