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 “bodypack” 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 me

Introduction
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 wireless microphone system
is the successful result of years of design and manufacturing
experience.
Each DR-1000 Series professional VHF wireles
a receiver and either a body-pack transmitter or a
handheld microphone/transmitter on a specific crystal-controlled
frequency.
Because DR-1000 Series packaging is designed to hold all
versions of the system, some compartments in the carton are
intentionally left empty.
The DR-R11 receiver includes a space-saving switching power
supply that automatically adapts to changes in mains voltage.
Unlike bulky linear power supplies, this switching powe
is lightweight and compact; it uses only a single outlet space.
The versatile DR-T15 UniPak
high-impedance input for instruments, and a low-impedance
input with bias connection for use with dynamic and electret
condenser microphones. The DR-T16 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 sw
(level) adjustments and battery-save switches.

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 reflections. Keep the receiver
antennas away from noise sources such as digital equipment,
motors, automobiles and neon lights, as well as away from
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 receiv
ers to help assure
maximum RF performance.
Output Connection
The receiver provides unbalanced, aux-level output from a
TS (“mono”) phone jack; an output cable is not included. Use
a shielded audio cable with
1
/4" phone plug to connect the
1
/4"
receiver’s AF Out jack to the mixer/amplifier’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. Secure the cord
over the cord hook on the back of the
receiver, to keep the
plug from being detached by an accidental tug on the cord.
Then plug the adapter into a standard 120 Volt 60 Hz AC power
outlet.
(Note that the receiver has no power Off/On switch. The
receiver will be energized whenever the power adapter is
connected and plugged into the AC outlet. Unplug the power
supply from the AC outlet when the system is not in use –
both for safety, and to conserve energy.)
Antennas
A novel “dipole” antenna system on the receiver improves
operation by providing a “ground” element in addition to the
usual “si
gnal” element. Position the two antennas at 90° in the
form of a “V,” or position the left (“signal”) antenna vertically
and the right (“ground”) antenna horizontally, in the shape of
an “L” (Fig. A). Use the position that performs better in your
operating environment. Be certain to extend both antennas to
their full 15" (38 cm) length by holding them at their bases and
pulling out on their caps. Both antenna elements may be
swiveled to the left and right, but do not attempt to rot
ate them
in a screwing/unscrewing motion. To do so may damage the
antenna and/or receiver. For best performance, locate the
receiver so its antennas are in direct line-of-sight to the
transmitter's likely operating position.

Transmitter Setup
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.

the input connector on the bottom of the transmitter. The
cable connector latches automatically when inserted into the
transmitter jack. To unlatch and remove the connector, simply
pull up on the connector’s knurled metal collar.
A number of Audio-Technica professional microphones and
cables are available separately, pre-terminated with a UniPak
™
input connector (see “Optional System Accessories” on
page 7).
Transmitting Antenna
The UniPak
™
nsmitter includes a permanently attached
tra
flexible antenna. For best results, allow the antenna to hang
freely and full length from the bottom of the transmitter. If the
received signal is marginal, experiment with different transmitter
positions on your body or instrument; or try repositioning the
receiver. Do not attempt to remove, replace or change the
length of the transmitting antenna.
3. Screw the body back together. Do not overtighten.
Battery Condition Indicator
The red battery condition indicator (Fig. H/I) should light strongly
with a fresh battery. As the battery weakens, the indicator will
grow dimmer. When the indicator becomes very di
m or goes
out, there is little life left in the battery. Replace it at once for
continued operation of the transmitter.
All transmitters feature battery-save switches (Fig. D/F). As
supplied, the switch is set in the High position for maximum
range. Switching to the Low position increases battery life by
reducing power. (Note: Effective range decreases when the
switch is set in Low position.)

System Operation
Turn down the receiver volume control and the mixer/amplifier
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. The green
Power indicator on the front panel will light.
Transmitter on...
When the transmitter is switched on, the receiver’s yellow RF
signal indicator will light. The transmitters have a 3-position
power switch. When t
he 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 amplifier.
Input Level Adjustment

immer controls in the transmitters enable you to
maximize performance for a particular microphone or guitar
sensitivity, or to adjust for different acoustic input levels.

and the acoustic input level are not changed.
Adjusting Input Level - Handheld Transmitter
Unscrew the lower body cover and slide it downward, exposing
the screwdriver and Gain Trimmer control (Fig. G). Remove the
screwdriver from its clip. Gently turn the control to its full
clockwise position (toward the side marked “H”), the factory
setting. Check for excessive gain by speaking/singing in
to the
microphone at typically-loud levels while watching the receiver’s
AF Peak indicator. If the AF Peak indicator does light, turn the
Gain Trimmer control slightly counterclockwise until the AF Peak
indicator no longer lights with maximum audio input to the
mic/transmitter.
Return the screwdriver to its clip and close and secure the
lower body. No further transmitter gain adjustments should
be needed, as long as the acoustic input does not change
significantly.
CAUTION! The small trimmer controls are delicate; use
only the supplied screwdriver. Do not force the trimmers
beyond their normal 190

Ten Tips To Obtain The Best Results
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 outpu
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 off when not in use. Remove the battery if
the transmitter is not to be used for a period of time.
