Notice to individuals with implanted cardiac pacemakers
or AICD devices:
Any source of RF (radio frequency) energy interfere with normal may
functioning of the implanted device. All wireless microphones have
low-power transmitters (less than 0.05 watts output) which are unlikely
to cause difculty, 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.
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 in 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 or frequency selection, please contact
your dealer or Audio-Technica. Extensive wireless information also is
available at www.audio-technica.com.
Thank you for choosing an Audio-Technica professional wireless
system. You have joined thousands of other satised 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 frequencies in one of ve UHF frequency ranges,
available for exible performance in a wide variety of regions
worldwide:
Frequency Range
Band D 656.125 – 678.500 MHz
Band E 795.500 – 805.875 MHz
Band F 854.900 – 864.900 MHz
Band G 722.125 – 744.500 MHz
Band I 487.125 – 506.500 MHz
Band U 606.500 – 629.900 MHz
The band letter reference at the end of 2000 Series Stock Numbers
indicates what band system/component operates in. For simplicity,
model numbers used throughout this manual will reference only the
basic model number without the band indications.
Each wireless system includes a receiver and either a body-pack or
handheld transmitter. UniPak® body-pack transmitter systems include
accessory microphones for particular applications. All A-T Wireless
Essentials® microphones and cables, available separately, are pre-
terminated for use with any Audio-Technica 2000 Series wireless
system.
The ATW-R2100b 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. The receiver also
offers a switchable output attenuator to reduce the level of the output
signal by 12 dB for exible use with a variety of system congurations.
2000 Series Installation and Operation

Switchable antenna power is also provided. 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-T210a 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 UniPak
® transmitter also offers separate trim
controls for instrument and microphone, plus switchable high/low RF
power.
The ATW-T220a handheld dynamic microphone/transmitter features
the same element used in the PRO 41 dynamic handheld microphone
created for professional live-sound venues. It also offers switchable
high/low RF power. Both the ATW-T210a UniPak® and ATW-T220a
handheld transmitters also offer charging contacts so the units can be
placed in an optional recharging station for multi-transmitter charging.
For economical operation and wide availability, transmitters in the
2000 Series use two 1.5V AA alkaline batteries or rechargeable two AA
NiMH batteries for use with Audio-Technica’s ATW-CHG2 Recharging
Station. 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 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) per
band that are used in the 2000 Series have been selected for multi-
channel compatibility. Subject to frequency availability in a particular
geographic area, any of these 10 channels may be used together. The
operating frequencies that correspond to each of the 10 channels are
listed on page 10.
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
reections. 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.
Fig. A
Output Connections
There are two audio outputs on the back panel: balanced and
unbalanced. 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 audio-technica.com for a wide
selection of wireless system accessories.
Antenna Power
The antenna input jacks also can provide +12V DC output on their
center pins to power inline RF devices. A maximum of 60 mA can be
drawn from each of the jacks. While an accidental short-circuit will not
harm the internal 12V supply, make certain that an antenna cable shield
does not contact the center conductor. Antenna Power is selected by
a switch on the back of the ATW-R2100b Receiver. The unit is shipped
with the switch in the “off” position.
Note: the antennas included with the ATW-R2100b Receiver do
not require power. If you have an antenna system that requires power
(such as powered antennas or active combiners or splitters) switch the
Antenna Power switch to the on” position.
Power Connections
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. Operation of the receiver is controlled by the front-
panel Power switch.
