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 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.

Thank you for choosing this Audio-Technica 3000 Series Frequency-agile
True Diversity UHF Wireless System.

The 3000 Series wireless system is available in six UHF frequency
bands to provide exible performance in a wide variety of regions
worldwide:

Frequency Range Number of frequencies
Band C 541.500 – 566.375 MHz 996
Band D 655.500 – 680.375 MHz 996
Band E 795.500 – 820.000 MHz 981
Band F 840.125 – 864.900 MHz 953
Band G 721.500 – 746.375 MHz 996
Band I 482.000 – 507.000 MHz 1001
Band U 606.000 – 631.000 MHz 1001

The band letter reference at the end of 3000 Series Stock Numbers
indicates what band the 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 may
include an accessory microphone for a particular application. All A-T
Wireless Essentials® microphones and cables, available separately, are
pre-terminated for use with any Audio-Technica 3000 Series wireless
system.

All 3000 Series components feature soft-touch controls for quick, easy
access to a formidable range of functions; an LCD information display
in each unit provides convenient visual indication of unit settings and
operation.

The ATW-R3100b receiver is equipped with automatic frequency
scanning for easy setup. It also 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 a variety of functions, while a backlit LCD
information display provides constant monitoring of system operation,
including indication of the transmitter’s battery status. 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-T310b UniPak® body-pack transmitter has both
low- and high-impedance inputs, plus a bias connection for use with
electret condenser microphones, as well as Hi-Z instrument pickups.
In addition to its programmable functions, the transmitter features
a three-position sliding cover to limit access, if desired, to just the
Power/Mute button, or to cover all the controls, as appropriate for the
application and user. The ATW-T341b handheld dynamic microphone/
transmitter features the same element used in the Artist Elite® AE4100
dynamic handheld microphone created for professional livesound
venues. The ATW-T371b handheld condenser microphone/transmitter
features the same element used in the Artist Series ATM710 cardioid
condenser vocal microphone.

Transmitters in the 3000 Series use two 1.5V AA batteries for
economical operation and wide availability. The receiver and both
transmitters have “fuel gauge” battery condition indicators with
low-battery warnings.

An advanced Digital Tone Lock™ tone squelch system in the
ATW-R3100b receiver opens only when a 3000 Series transmitter

is detected, reducing the possibility of interference. As a result, 3000
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. Exception: 3000 Series
components are compatible with Audio-Technica 1800 Series wireless
system components.

Please note that in multiple-system applications there must be a
transmitter-receiver combination set to a separate frequency for each
input desired (only one transmitter for each receiver). Because the
wireless frequencies are within UHF TV frequency bands, only certain
operating frequencies may be useable in a particular geographic area.

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.

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 8 m/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.

Either passive or active antennas may be used. Both input jacks
offer switchable +12 V DC output on their center pins to operate
Audio-Technica powered antennas or other in-line RF devices if desired.
Up to 60 mA can be drawn from each antenna input jack.

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. Then plug the AC adapter into an AC power outlet.
Operation of the receiver is controlled by the front-panel Power switch.

Up/Down Arrow Buttons
In conjunction with the Mode/Set button, the arrow buttons permit
moving through the menu of functions, and they offer a choice of
settings within each function.

Mode/Set Button

The Mode/Set button shifts the receiver from normal operation into
Menu mode and, in conjunction with the Up/Down arrow buttons,
permits selection of different features and changing of their stored
values in the Edit mode.

How to Make Setting Changes

1. From the normal operating mode, press the Mode/Set button once
to enter the Function Menu mode. (Only the frequency will remain
in the LCD window, and the receiver’s audio output will be cut off.)

2. Use the Up/Down arrow buttons to reach the desired function.
The value in the LCD window is the current setting for that function.

3. Press the Mode/Set button once again to open the list of available
choices for that function. The value will ash, indicating that it can
be changed (Edit mode).

4. Use the arrow buttons to go through the available choices, stopping
on the desired new choice.

5. (a) To accept and enter the new choice, press and hold the Mode/
Set button until “STORED” appears in the LCD. This changes the
value and puts the function of the buttons back at Menu level (step
2 above). (The “B” tuner light will come on while the Mode/Set
button is depressed, to conrm its action.)
(b) To “back out” of the Edit mode without making a new choice,
simply press the Mode/Set button once. The word “ESCAPE” will
appear in the window and the function of the buttons will revert to
the Menu level (step 2 above), without making any changes.

6. Repeat this selection process for any other function changes
desired. When nished with any changes, use the arrow buttons to

move to “QUIT”. Press the Mode/Set button once to exit the
menu and return the receiver to normal operation. (“RF” and “AF”
will reappear in the window, indicating the return to normal receiver
operation, with the receiver’s audio output again enabled.)

Frequency Group Selection

To select a frequency scan group, press the Mode/Set button, then use
the arrow button until the desired group appears in the display. To store
the selected frequency scan group, press the Mode/Set button to enter
the desired group; then use the arrow button to start the scan. When a
ashing number is displayed, press and hold Mode/Set button to select
the frequency. See detailed instructions in System Operation.

How to Restore Default Settings

To return all the receiver functions to their original factory default
settings, rst turn the receiver off. Then hold in the Mode/Set button
while pressing and releasing the Power switch. The LCD will briey
show “RESET”, followed by “WAIT” (release the Mode/Set button),
before commencing normal-mode operation at the default settings.

When the receiver is in the Menu or Edit mode, its audio output is
silenced. Once control-setting operations are completed (or Escape
is used), normal receiver operation will resume with its audio output
restored.

While in the Edit mode, if no action is taken for approximately 30
seconds (no buttons pressed), the receiver will “back out” to the Menu
mode. Similarly, after about 30 seconds of inaction in the Menu mode,
the receiver will “back out” to normal receiver operation with audio
output restored.

High-pass Filter

Internal high-pass lter circuitry may be set to four positions: High­pass Off, or a 6 dB, 12 dB or 18 dB slope at 150 Hz. The default
setting is Off (“HP OFF”). Increasing the slope of the high-pass lter
further suppresses unwanted low frequencies, while maintaining the
frequency response in the desired audio range.

Meter Hold Setting

When activated (“MH ON”), this function permits the bar-meters in
the LCD window to capture and display the highest-level “AF” audio
modulation (a solid bar) and the lowest-level “RF” signal (a ashing bar)
received from the transmitter. This is particularly useful when setting
up the system initially, during a sound- check, or when diagnosing
operating problems. The default setting is Off (“MH OFF”).

When the Meter Hold is On, it is possible to reset it – to obtain a new
set of RF and AF readings – without turning it off-and-on using the
Menu/Edit functions. Simply press the transmitter’s Power/Mute button
once (to mute the transmitter) and wait until the receiver’s Alert light

comes on, indicating the Mute condition. Then press the transmitter’s

Power/Mute button once again, to un-mute the transmitter. After the

Alert light goes out, a new set of min/max RF/AF readings will be

indicated on the bar-meters. (Note that, depending upon the digital
updating- and-conrming sequence of the Mute condition data from
the transmitter, it may take several seconds for the Alert light condition
to change. The Meter Hold function is not reset until the Alert light

has turned on, then turned off.)

Digital Tone Lock™ Squelch

The 3000 Series employs a unique Digital Tone Lock squelch system
that provides enhanced rejection of interference. In addition to providing
highly effective control of unwanted noise, the Tone Lock signal from
the transmitter also conveys data on the transmitter’s battery condition
and mute status back to the receiver for display.

3000 Series Installation and Operation

5

The squelch level is adjustable from 15 dB (the default value) to 39 dB
in 6 dB steps. Increasing the squelch level – also called “tightening
the squelch” – can cause a reduction in useable range of the wireless
transmitter, so use the lowest value that reliably mutes the unwanted
RF signals. (If interference is a problem, rst consider trying a different
frequency.)

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 (“ANT.PWR”) is
selected (switched on or off) from the LCD menu.

Pre-coordinated Frequency Scan Groups 1-9

The nine scan groups provided on the 3000 Series receivers simplify
the selection of usable frequencies in a multi-channel wireless system.
If you are using multiple systems, stay within one of the nine frequency
groups for all of your systems. The available frequencies within each
group have been selected for simultaneous use, eliminating the
frustration encountered when trying to select compatible frequecies in
a multi-channel system.

Scan Groups 8 and 9 have been designed to allow for use on adjoining
stages. Use Group 8 on one stage and Group 9 on a second nearby
stage. Or use these two groups in two different rooms, with one room
using Group 8, and the second using Group 9.

Transmitter Controls And Functions

Refer to Figures E, F, G and H for an overview of transmitter features
and controls.

LCD Window

The backlit Liquid Crystal Display presents a great deal of setup and
operating information clearly and conveniently (See examples in Fig. J).
The LCD in the transmitters is designed for greatest contrast and best
viewing with the window rotated somewhat away from the viewer
(about 30 degrees), not straight-on, for a more convenient holding/
viewing position. The display is illuminated with a backlight when you
power on the device and when you press Set to access transmitter
functions. The backlight remains on during the Set process, only
turning off if no action is taken within 30 seconds or if Quit is pressed;
otherwise, it automatically turns off in ten seconds.

Power/Mute Button
The transmitters have a combination Power and Mute switch. When
used in combination with the programmed choices explained below,
the various functions available to the transmitter user may be tailored to
t personal preferences or particular situations of use.

Power On/Off

To turn the transmitter on, press and hold the Power/Mute button until
the green power indicator and the LCD window come on (about 1-2
seconds). The operating frequency will show in the window after the
power-up sequence.

To turn the transmitter off, press and hold the Power/Mute button again,
until the green power indicator and the LCD window are extinguished
(about 1-2 seconds). The LCD window will show “PWR.OFF” before
shutdown.

Mute Off/On

When the transmitter is muted, it produces RF with no audio signal

modulation. When the transmitter is un-muted, it produces both RF and
audio.

To mute the transmitter (cut off the audio, but continue the RF output),
press and release the Power/Mute button once. A small “MUTE” will
appear in the LCD window, just below the frequency (Fig. M-2) and the
power/mute LED will change from green to red.

To un-mute the transmitter (restore the audio), press and release the
Power/Mute button once again. The “MUTE” will disappear from the
LCD window and the power/mute LED will change from red to green.

Power/Mute Locks

Programmable Power/Mute Locks limit the functioning of the Power/
Mute button as desired for particular users and/or applications. Power
can be locked On; Mute can be locked Off. Selection of the desired
locks, if any, is made through the function menu:

Setting Description
NO.LOC The normal Power and Mute functions are fully

operational.
ALL.LOC Both the Power and Mute functions are locked
into their status as of the time “ALL.LOC” is
applied. (Power On, and Mute either On or Off.)
Note: ALL.LOC must be re-accessed and the
setting changed to turn the transmitter off.
MUT.LOC In this mode, the audio cannot be muted.
The Power functioning is unaffected. (If MUT.LOC is
applied while the transmitter is muted, pressing
the Power/Mute button once will return to
un-muted operation; thereafter the Mute function
is disabled until the setting is changed again.)
PWR.LOC Power is locked On as of the time “PWR.LOC”
is applied. The Mute functioning is unaffected.
Note: When in the PWR.LOC mode, the
transmitter may be turned off by: (1) Re-accessing
the .LOC Menu and changing the setting, or
(2) Removing and re-installing the batteries. When
the transmitter is turned on again, it will power-up
in the NO.LOC mode. (Only the PWR. LOC
function will change when batteries are removed;
all other settings remain stored in memory.)

If an attempt is made to take an action that currently is locked
out, the LCD will display “LOCKED” briey, then return to its
previously-displayed contents.

3000 Series Installation and Operation

Transmitter Setup

Battery Selection and Installation

Each transmitter uses two 1.5V AA batteries, not included. Alkaline
type is recommended; other types of 1.5V AA batteries (including
rechargeable) may be used, however performance may vary. Always
replace both batteries. Make certain the transmitter power is Off before
replacing batteries.

UniPak® Transmitter Battery Installation

1. Open the battery compartment door as follows:
Slide door lock down to the unlocked position. Pinch the release
arrows together to open the compartment. (Fig. J)

2. Observe correct polarity as marked on the metal contacts on the
door and carefully insert two fresh 1.5V AA alkaline batteries (Fig. K).

3. Close the door, making certain the latch clicks securely in place.

4. Slide the door lock up to the locked position.

Serial Number

Start from this end
to remove batteries

The transmitter’s “fuel gauge” battery indicator displays a maximum of
four bar segments. When it ashes “LOW.BAT”, the batteries should
be replaced immediately to ensure continued operation. (The receiver
also displays transmitter battery condition in the LCD window with
bar segments; the Alert indicator comes on to warn of a low-battery
condition.)

UniPak® Transmitter Input Connection

Connect an audio input device (microphone or guitar cable) to the audio
input jack on the transmitter. A number of Audio-Technica professional
microphones and cables are available separately, pre-terminated with
a UniPak input connector. 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.

UniPak® Transmitter Antenna

The UniPak transmitter includes a eld-replaceable exible antenna.
For best results, allow the antenna to extend to its 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 or using remote receiver antennas. Since the transmitter
antenna simply screws in, check it occasionally to make certain it
is snugly attached (nger-tight). Do not change the length of the

transmitting antenna.

Handheld Transmitter Antenna

The antenna for the handheld mic/transmitter is in the black,
non-metallic section at the bottom of the unit (Fig. F). For best results,
hold the mic/transmitter naturally, around its painted metal case;
holding or otherwise covering the antenna housing may reduce the
operating range.

UniPak® Transmitter Mounting Clip

The UniPak transmitter’s mounting clip may be installed with the case
positioned either “up” or “down,” depending upon which is preferred
for the application. To turn the clip around, pull the ends of the clip
out of the two holes on the sides of the transmitter case (Fig. E) and
reinstall it facing in the opposite direction.

Handheld Transmitter Battery Installation

1. While holding the lower body cover (near the LCD window), grasp
the upper part of the transmitter body just below the grille and
unscrew it at least four complete turns (Fig. G); then slide the
lower body cover down until it stops (Fig. H). Once the cover
has been lowered, turn the transmitter over to reveal the battery
compartment on the side opposite the LCD window.

2. Observe correct polarity as marked inside the battery compartment
and carefully insert two fresh 1.5V AA batteries (Fig. L). Insert the
rst battery and slide it down. Then insert the second battery,
bottom rst, into the space remaining. Make certain the batteries
are fully seated in the battery compartment.

3. Slide the lower body cover back up the body, then screw the
housing together. Do not overtighten.

Note: Remove batteries from the handheld transmitter starting at
the bottom (– end) of the top battery (Fig. L). The top (+ end) of the
top battery is captured in a recess and will not come straight out.

Battery Condition Indicator

After the batteries are installed, turn the power on by pressing and
holding the Power/Mute button. The small power-on LED (Fig. E/F)

should light green and the LCD window should come on. If this does
not happen, the batteries are installed incorrectly or they are dead.

3000 Series Installation and Operation

System Operation

Turn the receiver on by pressing in the Power switch. Do not switch on
the transmitter yet.

The Alert indicator and the LCD window will light up; the normal­operation LCD display will appear after 1-2 seconds (Fig. D-1). If
any of the bars show in the “RF” bar-graph meter, there may be RF
interference in the area. If this occurs, select another frequency as
explained below. (If the Meter Hold function has been selected, one of
the RF bars will be ashing, indicating the lowest RF level received.)

Selecting/Setting Frequency

Selection of the desired operating frequency is made through the
function menus. It’s usually best to start by setting the receiver’s
frequency, to determine there is no local interference on that frequency.
Then, always make certain to set the transmitter to the receiver’s exact
frequency. The receiver’s unique Digital Tone Lock system squelches
the audio only, permitting any RF energy on the frequency to show on
the “RF” bar-meter.

Note: It is often convenient to start with the factory-default frequency,

if there is no RF energy showing on the RF bar meter.

Using the Automatic Scan Function to Set Receiver Frequency

1. Press the Mode/Set button once; then the “RF” and “AF” scales will
disappear from the window and only the frequency will appear in
the LCD window. (The receiver is now in the Menu mode.) See
Figure D-2.

2. Use the Up arrow button to reach Group 1 through Group 9. Press
the Mode/Set button once to select one of these nine scan groups.
The lowest frequency in the selected scan group will appear in the
LCD window.

3. Press the Up arrow button to begin the scan. “G SCAN” will ash in
the LCD window.

4. The rst available frequency will ash in the LCD window. To
activate this frequency selection, press and hold the Mode/Set
button until the word “STORED” appears in the LCD window. (If you
do not wish to complete this particular selection, just press the
Mode/Set button once. The word “ESCAPE” will appear briey in
the window and the receiver will return to the Menu mode.)

5. After you have activated your frequency selection (step 4), the “RF”
and “AF” scales will reappear in the window, indicating the return to
normal operation.

6. If you are using multiple systems, all frequencies must be selected
from the same group (Group 1 through Group 9). After completing
the rst receiver’s scan and frequency selection, set the transmitter
to the same frequency (see Setting Transmitter Frequency
instructions); leave the transmitter On, and run the next
receiver’s automatic scan function. Always set a receiver-transmitter
pair to the same frequency before using the automatic scan function
to select a frequency for the next receiver. “End” will show on
the receiver display when no further usable frequencies remain in
the selected scan plan.

NOTES ON USING THE RECEIVER SCAN FEATURE:

• Selecting low power on your transmitter can be helpful for multiple
system setup, if you are experiencing problems with radio
frequency interference.

• To prevent raised noise oors that a receiver scan might interpret as
radio frequency interference: during setup, keep all transmitters at
least three feet apart and at least 15 feet from the receivers.

Setting Receiver Frequency Manually

1. Press the Mode/Set button once; then only the frequency will
appear in the LCD window. (The receiver is now in the Menu mode.)
See Figure D-2.

2. Press the Mode/Set button again; the Alert light will come on and
the rst three digits of the frequency will ash in the window.
(The receiver is now in the Edit mode, Fig. D-3.)

3. Use the Up/Down arrow buttons to change the rst three digits
(MHz) to the desired frequency. Choose a frequency appropriate
for your area, avoiding frequencies with active TV channels. Press
either arrow for single steps, or hold down either arrow for rapid
cycling through the band. Frequencies “wrap around” to the other
end of the range when the top or bottom of the band is reached.

4. Press the Mode/Set button once to set the rst three digits to the
desired frequency.

5. Use the Up/Down arrow buttons to change the second three digits
(kHz) to the desired frequency. Again, be certain to choose a
frequency appropriate for your area, avoiding frequencies with active
TV channels.

6. To activate this frequency selection, press and hold the Mode/Set
button until the word “STORED” appears in the receiver’s window.
(If you do not wish to complete this particular selection, just press
the Mode/Set button once. The word “ESCAPE” will appear briey
in the window and the receiver will return to the Menu mode.)

7. When nished entering a frequency, press the Down arrow button
once to move to “QUIT”. Then press the Mode/Set button once to
exit the menu. The “RF” and “AF” scales will reappear in the
window, indicating the return to normal operation.

4. Use the Up/Down arrow buttons to change the second three digits
to the desired frequency.

5. To activate this frequency selection, press and hold the Set button
until the word “STORED” appears in the transmitter’s window. (If
you do not wish to complete this selection, just press the Set button
once: the word “ESCAPE” will appear briey in the window and the
transmitter will return to the Menu mode.)

6. When nished entering a frequency, press the Up arrow button
once to move to “QUIT”. Then press the Set button once to exit
the menu. The word “MENU” in the transmitter window will go off,
indicating the return to normal operation.

When the transmitter is switched on and in normal operation, the
receiver’s “RF” signal-level bars will display from bottom to top,
with more bars indicating increased signal reception. For optimum
performance at least four, and preferably ve or more, of the RF
indicators should be displayed.

Setting Transmitter Audio Input Levels

Correct adjustment of transmitter audio input, receiver audio output,
and mixer/amplier input and output levels is important for optimum
system performance.

ATW-T310b and ATW-T341b Transmitters

A 4-position audio input gain setting, selected through the function
menu, serves to match the audio input level to the transmitter for best
modulation with minimum distortion. Available choices are +12 dB,
+6 dB, 0 dB and -6 dB. The default value is +6 dB. Select the highest
setting that does not result in over-modulation with the highest audio/
instrument input levels (an AF indication on the receiver no higher than
“0”).

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 no closer than three feet (1 m).

4. Avoid placing the receiver in a low or shielded location where the
transmitter and receiver antennas are not within line-of-sight. If
necessary, use remotely-located receiver antennas.

5. Avoid placing the receiver near computers or other RF generating
equipment.

6. The receiver and transmitter must be set to the same frequency.

7. A receiver cannot receive signals from two transmitters at the same time.

8. Do not obstruct the handheld transmitter’s antenna (located at the
base) or attached body-pack transmitter’s antenna with your hands.

9. You need to change frequencies 1) when a strong interference
signal is received, 2) when audio quality is poor due to weak RF, or

3) during multiple-system operation in order to select an
interference-free frequency.

10. Turn the transmitter off when not in use. Remove the batteries if the
transmitter is not to be used for a period of time.

ATW-T371b Transmitter

A 3-position audio input gain setting, selected through the function
menu, serves to match the audio input level to the transmitter for best
modulation with minimum distortion. Available choices are +12 dB, +6
dB, and 0 dB. The default value is +6 dB. In addition, a mechanical pad
switch on the condenser capsule (inside the screw-on wire mesh grille)
can provide another 6 dB of attenuation. For best performance, adjust
the input level using the function menu choices, keeping the capsule’s
mechanical switch at 0 dB. If more audio attenuation is needed than the
menu provides, then set the capsule’s pad switch to -6 dB.

RF Power Adjustment

RF power may be set to “RF HI” (30 mW nominal) or “RF LOW”
(10 mW nominal) through the function menu. The default setting is “RF
LOW”. While the High setting normally provides maximum operating
range, the Low setting will help extend battery life. The Low setting
may also be preferred in multichannel systems, or when operating very
close to the receiver, to reduce the possibility of interference
or overload.

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.

Troubleshooting Guide

Receiver is not on (LCD window does not light).

• Receiver Power switch is not pressed in.

• Small DC power cord from included in-line power supply
is not plugged into jack on back of receiver. (Use the cord
hook to secure it.)

• The in-line power supply is not plugged into AC power outlet.

• AC power is not present at the AC outlet.

Receiver is on (LCD window lights).

- No sound - Alert light is OFF:

3 “RF”, “AF” and “BATT” legends do not appear in LCD.

• Receiver is in the Menu mode.

3 “RF” and “AF” level meters both show good signals.

• AF Level control on back of receiver not turned up (clockwise).
Note: If the “AF” level meter shows a good signal on the receiver
when the transmitter is receiving audio input, and the AF Level
control is turned up, then the problem is in connections to or
control settings on the mixer, amplier, etc.
3 Only “RF” level meter shows good signal; no “AF” signal.

• No sound input to mic.

• ATW-T310b body-pack only: Wrong input selected (“INST”
or “MIC”).

Receiver is on (LCD window lights).

- No sound - Alert light is ON:

• Signal blockage or interference from large metal objects, other
wireless units located too close and/or on incompatible
frequencies, computer or lighting equipment.

• Squelch setting may be set “tighter” than it needs to be.
(Recommended squelch setting is the minimum/default value,
15 dB.)
Tip: Use the Meter Hold function to help identify and resolve (or
at least avoid) RF problem locations.

With transmitter on, received signal is noisy or contains
extraneous sounds.

• Batteries may be weak. Check “BATT” fuel gauge and “RF”
meter level.

• Local TV transmissions on this frequency.

• Nearby sources of RF interference, such as computers, lighting
equipment, etc.

• Two transmitters may be operating on the same frequency.
Locate and turn one off or change its frequency.

• In multiple-system use, two (or more) incompatible frequencies
may have been selected.

3 “RF”, “AF” and “BATT” legends do not appear in LCD, and
LCD is ashing.

• Receiver is in the Edit mode.

3 “RF” and “AF” level meters both show good signals.

• The transmitter audio level is too high
(“+3”/”+6” on receiver).

• Batteries may be weak. (Check “BATT” fuel gauge.)

3 Only “RF” level meter shows good signal; no “AF”signal.

• Transmitter may be muted. (Note: Normally it takes several
seconds for the Alert light to turn off/on after the transmitter
mute is switched off/on.)

3 Neither the “RF” nor the “AF” level meter shows any signal.

• Receiver antennas not connected.

• Transmitter is turned off.

• Transmitter batteries are dead or missing.

• Transmitter is set to a different frequency.

• Transmitter and receiver not in same Band.

Receiver is on (LCD window lights).

- Distorted sound - Alert light is ON:

3 “RF” and/or “AF” level meters may show good signals.

• The transmitter audio level is too high (“+3”/”+6” on receiver).

• Received RF level may be too low (only one or two bars).

• Batteries may be weak; check “BATT” fuel gauge. (Sound may
or may not be distorted.)

Momentary loss of sound/noisy sound as transmitter is
moved around performing area.

• Transmitter and receiver antennas not in line-of-sight (or perhaps
too far apart). Adjust positions of units so they are visible to each
other/closer together; use remote antennas located closer to the
transmitter location.
