CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
Warning: This apparatus must be grounded.
This product is a safety class 1 product.
There must be an uninterruptible safety earth
ground from the main power source to the
product‘s AC input. Whenever it is likely that
the protection has been impaired, disconnect
the power cord until the ground has been
restored.
Attention: Cet appareil doit être mise à la
terre. Cet appareil est de classe de sûreté 1.
Il doit y avoir un ininterrompable de mise à la
terre de sécurité provenant de la source
principale de courant de l‘appareil de l‘entrée
du courant alternatif. Quand la protection a été
affaiblie, débrancher le fil de courant jusqu‘à la
mise à terre a bien été réétablie.
Warning: To prevent fire or shock hazard, do
not expose this appliance to rain or moisture.
Attention: Pour prévenir feu ou choc
électrique, ne pas exposé l’appareil à la pluie
ou à l’humidité.
Caution/Avis: For continued protection
against fire hazard, replace only with same
type/rating of fuse.
Pour poursuivre la protection contre le feu,
replacez la fusible de même type/cote.
Warning/Attention: There are some sharp
edges inside. To reduce the risk of injury,
do not remove cover.
Bord tranchant à l‘intérieur. Pour réduire le
risque de blessure, ne pas ouvir le couvercle.
To prevent electric shock, do not remove the
cover. There are no user-serviceable parts
inside. Internal adjustments are for qualified
professionals only. Refer all servicing to
qualified service personnel.
Pour prévenir un choc électrique, ne pas ouvrir
le couvercle. Il n’y aucune pièces de rechanges
à l’intérieur. Tout ajustement interne doit être
fait par une personne qualifié seulement.
Référez tout réparation au personnel qualifié.
Location
For best operation the receiver should be at least 3 ft.
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 large
metal objects.
Introduction
Audio-Technica Engineered Sound®wireless systems are
offered as separate receiver and transmitter units, rather
than in predetermined combinations, for greatest system
flexibility. Operating details for Engineered Sound transmitters are included with each transmitter.
Engineered Sound receivers feature a sophisticated Tone
Lock
™
tone squelch system that opens only when an
Engineered Sound transmitter is detected, reducing the
possibility of interference. As a result, Engineered Sound
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.
The ESW-210 Receiver offers 100 PLL-synthesized UHF
frequencies and true diversity reception. Two antennas feed
two completely independent RF sections (Tuners) 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 ESW-R210 also provides
+12V DC on the antenna jacks to power in-line RF devices.
The receiver is housed in a full-width standard 19" (1U)
rack-mountable case, with rack-mount adapters included.
Please note that in multiple-system applications there must
be a transmitter-receiver pair set to a separate frequency for
each input desired (only one transmitter at a time for each
receiver). Because the wireless frequencies are on UHF TV
frequencies, only certain wireless frequencies may be useable in a particular geographic area. Also, only certain of the
available operating frequencies may be used together in
multi-channel systems. (Suggestions for multiple-frequency
groupings will be found on page 7.)

Receiver Installation

Output Connections
There are two audio output jacks on the back panel:
balanced (4 mV) and unbalanced (40 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 tape
recorder and a mixer can be driven by the receiver.
Antennas
Attach a pair of UHF antennas to the antenna input jacks.
The antennas are normally positioned in the shape of a “V”
(45° from vertical) for best reception.
The antennas can be remotely located from the receiver.
However, due to signal loss in cables at UHF frequencies,
use the lowest-loss RF cable type(s) practical for any cable
runs over 25 feet. RG-8 is a good choice. Use only coppershielded cable, not CATV-type foil-shielded wire.
The antenna input jacks also provide +12V DC output on
their center pins to power in-line RF devices. Twenty (20)
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.
Power Connections
The switching power supply is designed to operate properly
from any AC power source 120-240V, 50/60 Hz without
adjustment. Simply connect to a standard AC power outlet,
using an IEC input cordset approved for the country of
operation. Use the included cable clamp to secure the plug
in the chassis connector. Power to the unit is controlled by
the front-panel Power switch.
Headphone Jack
A headphone jack on the front panel provides monitoring
of the receiver’s output. The
1
/
4
" TRS jack is intended for use
with stereo headphones. The “Phones” level control affects
the headphone jack only.
