CAUTION! Electrical shock can result from removal of
the receiver cover. Refer servicing to qualified 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.
This device complies with part 15 of the FCC Rules.
Operation is subject to the condition that this device does
not cause harmful interference.
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.
All units operate on ten switch-selected frequencies in one of
two UHF frequency ranges: Band “A” units in 470-480 MHz,
and Band “B” units in 482-492 MHz:
Band “A” Band “B”
470-480 MHz 482-492 MHz

The ATW-R600 receiver design features a novel “docking”
power supply configuration. An AC power adapter housed in a
compartment in the receiver uses an IEC-standard detachable
power cordset. Furthering its flexibility, the power adapter may
be easily removed from the receiver case, permitting its use as
a conventional in-line AC adapter.
The versatile ATW-T601 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-T602 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 switches, input Trim
(level) adjustments and battery condition indicators.
Note: 600 Series “A” Band transmitters must be used only with
“A” Band receivers; the same holds true for 600 Series “B”
Band transmitters and receivers. For multiple-mic applications,
as many as four systems in the “A” Band may be used together, and/or up to four systems in the “B” Band. This permits
multi-channel combinations with up to eight channels using only
600 Series systems.
Please note that in a multi-channel application, there must be a
transmitter-receiver combination on a separate frequency for
each input desired (only one transmitter for each receiver).
Because the 600 Series operates on UHF TV frequencies
(channels 14-15 or 16-17), only certain wireless frequencies may
be useable in a particular geographic area. (Frequency selection
information will be found on page 6.)
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 Freeway
™
600 Series professional UHF wireless system
includes a receiver and either a body-pack transmitter or a
handheld microphone/transmitter. ATW-601 UniPak body-pack
transmitter systems include models pre-packaged with either
an AT-GCW guitar cable (/G), a PRO 8HEcW headworn
microphone (/H) or an AT829cW lavalier mic ( /L) for particular
applications. All A-T Wireless Essentials
™
microphones and
cables, available separately, are pre-terminated for use with any
ATW-601 system.
Because Freeway packaging is designed to hold all versions of
the system, some compartments in the carton are intentionally
left empty.
Introduction
See pages 8-9 for illustrations.
Receiver Installation
3
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 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/amplifier’s aux-level input.
Power Connection
Turn the receiver’s volume control all the way down. If not
already connected, plug the small DC output cord from the AC
power adapter to the DC power input jack on the back of
receiver. Plug the power cordset into the power adapter, and
then connect the cordset to an AC source.
(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 cordset
from the AC outlet whenever the system is not in use – both
for safety, and to conserve energy.)
If desired, the power adapter may be removed from the receiver housing and used as an in-line supply. To remove the
adapter,
gently
pull the release tab
slightly
away from the
housing; then pull the power supply
straight back
out of the
receiver (Fig. A). Extend the 12V DC cord and/or the AC cordset as desired.
Front Panel Controls and Functions (Fig. C)
1. ANTENNAS: Position the “signal” antenna (1a) and
“ground” antenna (1b) as shown in Figure B. Fully extend
both antennas by pulling up on their end-caps.
2. CHANNEL SELECTOR: Chooses receiver operating
frequency. (Transmitter must be set to the same channel.)
3. POWER INDICATOR: Lights when power is supplied to
the receiver.
4. RF INDICATOR: Lights to show presence of transmitter
signal.
5. AF PEAK INDICATOR: Indicates when maximum
transmitter modulation without distortion has been
reached. Not affected by position of Volume control.
6. VOLUME CONTROL: Adjusts the audio level at the
1
/4"
output jack. Does not affect AF Peak indicator.
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. B). Use the position that performs
better in your operating environment. Be certain to extend both
antennas to their full 6
1
/4" (158 mm) length by 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.

7. AC POWER ADAPTER: Power supply “docks” inside
receiver housing, but can be removed to be used as an
in-line supply if desired.
8. RELEASE TAB: Pull down
slightly
to permit removal of
power adapter from receiver housing.
9. AC INPUT: Connect the AC cordset here.
10. DC POWER CORD: Connects the power supply’s 12-volt
DC output to the receiver’s DC input jack.
11. DC POWER INPUT: Connect the provided docking
power adapter, or other 12V DC source. (Receiver requires
200 mA.)
12. SQUELCH CONTROL: Adjusts level of noise-muting circuit
(preset at factory but can be adjusted as circumstances
warrant).
13. AUDIO OUTPUT JACK:
1
/4" TS (Tip-Sleeve) or “mono”
phone jack. Use a shielded cable to connect to an
unbalanced aux-level input of a mixer or amplifier.
