This device complies with part 15 of the FCC Rules. Operation is subject
to the condition that this device does not cause harmful interference.
A copy of the declaration of conformity can be found on the internet at
www.audio-technica.com.
This device complies with INDUSTRY CANADA R.S.S. 210, en
conformité avec IC: RSS-210/CNR210. Operation is subject to the
following conditions: 1) This device may not cause harmful interference
and 2) this device must accept any interference received, including
interference which may cause undesired operation. Changes or
modications not expressly approved by Audio-Technica could void your
authority to operate this equipment.
CAUTION! Electrical shock can result from removal of the receiver
cover. Refer servicing to qualied 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 difculty, 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.
Thank you for choosing an Audio-Technica professional wireless
system. You have joined thousands of other satised 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 System 8 professional VHF wireless system includes a receiver
and either a body-pack transmitter or a handheld microphone/
transmitter on a specic crystal-controlled frequency. ATW-801 UniPak®
body-pack transmitter systems include models pre-packaged with either
an AT-GCW guitar cable (/G), a PRO 8HEcW headworn microphone (/H),
a PRO 92cW headworn microphone (/H92), a PRO 92cW-TH headworn
microphone (/H92-TH), or a lavalier mic (/L) for particular applications. All
A-T Wireless Essentials® microphones and cables, available separately,
are pre-terminated for use with any ATW-801 system.
Because System 8 packaging is designed to hold all versions
of the system, some compartments in the carton may be intentionally
left empty.
The ATW-R800 receiver includes a switching power supply that
automatically adapts to changes in mains voltage.
The versatile ATW-T801 UniPak body-pack transmitter has both
a high-impedance input for instruments, and a low-impedance input
with bias connection for use with dynamic and electret condenser
microphones. The ATW-T802 handheld transmitter features a
unidirectional dynamic microphone element.
Both the body-pack and handheld transmitters use internal AA batteries
and have Power/Mute switches and input Trim (level) adjustments.
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 reections. 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 receivers to help assure
maximum RF performance.
Output Connection
The receiver provides unbalanced, aux-level output from a 1/4" TS
(“mono”) phone jack; an output cable is not included. Use a shielded
audio cable with 1/4" phone plug to connect the receiver’s AF Out jack to
the mixer/amplier’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 “signal”
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 rotate 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.

www.audio-technica.com).
UniPak® Transmitter Antenna
The UniPak® transmitter includes a permanently-attached exible
antenna. For best results, allow the antenna to hang freely and
full length from 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.

System Operation
Turn down the receiver volume control and the mixer/amplier
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 amber RF signal
indicator will light. The transmitters have a soft-touch power switch.
When the switch is set to “Mute” (red indicator LED), the transmitter
produces RF with no audio signal. When the switch is “On” (green
indicator LED) 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 amplier.
Input Level Adjustment
Input trimmer controls in the transmitters enable you to maximize
performance for a particular microphone or guitar sensitivity, or to
adjust for different acoustic input levels.
Adjusting Input Level - UniPak Transmitter
Slide the battery cover off the top part of transmitter and remove
the screwdriver from its clip (Fig. D). Gently turn both the “MIC”
(Mic Trimmer) and “INST” (Instrument Trimmer) controls to their full
counterclockwise positions (toward “L”).
• Microphone: Adjusting input level
Gently turn only the “MIC” (Mic Trimmer) control all the way
up (clockwise, toward “H”). Check for excessive gain by speaking/
singing into the microphone at typically loud levels while watching the
receiver’s AF Peak indicator. If the AF Peak indicator does light, turn
the “MIC” control slightly counterclockwise until the AF Peak indicator
no longer lights with maximum audio input to the transmitter.
• Guitar/Instrument: Adjusting input level
Gently turn only the “INST” (Instrument Trimmer) control all the way
up (clockwise, toward “H”). Check for excessive gain by playing at
typically loud levels while watching the receiver’s AF Peak indicator.
If the AF Peak indicator does light, turn the “INST” control slightly
counterclockwise until the AF Peak indicator no longer lights with
maximum instrument input to the transmitter. After adjusting input
level, return the screwdriver to its clip and reinstall the battery cover.
No further transmitter gain adjustments should be needed, as long as
the input device and the acoustic input level are not changed.
Adjusting Input Level - Handheld Transmitter
Unscrew the lower body cover and slide it off, exposing the screwdriver
and "LEVEL" (Gain Trimmer) control (Fig. C). Remove the screwdriver
from its clip. Gently turn the "LEVEL" control to its full clockwise
position (toward the side marked “H”), the factory setting. Check for
excessive gain by speaking/singing into the microphone at typically-loud
levels while watching the receiver’s AF Peak indicator. If the AF Peak
indicator does light, turn the "LEVEL" 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 signicantly.
CAUTION! The small trimmer controls are delicate; use only the
supplied screwdriver. Do not force the trimmers beyond their normal
190o range of rotation.
Return the screwdriver to its storage clip when not in use.
Ten Tips to Obtain the Best Results
1. Use only fresh alkaline batteries. Do not use “general purpose”
(carbon-zinc) batteries.
2. Position the receiver so that it has the fewest possible
obstructions between it and the normal location of the transmitter.
Line-of-sight is best.
3. The transmitter and the receiver should be as close together as
conveniently possible, but not less than 6' (2 m).
4. Do not place the receiver antennas within 3' (1 m) of another
receiver or antenna.
5. The receiver antennas should be kept away from any metal.
6. A receiver cannot receive signals from two transmitters on the same
frequency at the same time.
7. In the UniPak transmitter, the “MIC” or “INST” input control not
in use should be set to minimum.
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 output level of the
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.
10. Unplug the receiver from the AC outlet when the system is not
in use.
System Operating Frequencies
Frequency Selection
Each transmitter/receiver system operates on a single factory aligned,
crystal-controlled frequency. Available frequencies are shown in the chart
on the next page.
Operating frequency is specified by a two character code, such as
“T2,” in addition to the actual frequency in MHz. The frequency of each
transmitter appears on a label on the outside of the unit. The frequency
of each receiver appears on a label on the bottom of the unit and the
frequency of each system appears on the outer carton. For future refer-
ence, please record them in the space provided on page 7.
RF Interference
Please note that wireless frequencies are shared with other radio ser-
vices. According to Federal Communications Commission regulations,
“Wireless microphone operations are unprotected from interference
from other licensed operations within 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
