Description
The 1800 Series frequency-agile true diversity UHF wireless systems
provide a new standard for audio and RF performance with user-friendly
features and awless operation for camera-mount and special remote
applications. The systems provide the audio quality, range and reliability
necessary for the most demanding requirements of today’s video and
audio systems.
The ATW-T1801 UniPak® body-pack transmitter has both low and high
impedance inputs plus a 5V DC bias connection allowing it to be used
with condenser and dynamic microphones, as well as Hi-Z instrument
pickups. The locking 4-pin HRS-type audio input connector is recessed
to protect the connector from damage. Operating on two standard AA
batteries, the transmitter features high- and low-level RF output
settings. The low-level setting allows 2 additional hours of battery life
while retaining a strong RF signal link. Soft-touch controls provide
convenient access to a variety of functions including RF power, audio
input level, power/mute locks and frequency selection. The transmitter’s
backlit LCD display presents a great deal of setup and operating
information clearly and conveniently including battery fuel remaining,
mute, and operating frequency. A two-color LED, which can be seen from
the top or side of the transmitter, indicates power on and mute status.
A ashing “Lo-Batt” alert visually signals the battery is almost depleted.
Programmable power/mute locks limit the functioning of the transmitter’s
power/mute button as desired for particular users and applications. To
match the audio input level to the transmitter, a ve-position audio input
gain setting selected through the function menu is provided.

antenna and captive battery cover door.
Additionally, the frequency conguration used in the 1800 Series
components allows them to be interchangeable with the Audio-Technica
3000 Series components.
Architect’s and Engineer’s Specications
The frequency-agile FM body-pack transmitter shall be part of a wireless
microphone system consisting of a receiver and the appropriate transmitter. Operating in the UHF bands of either 541.500 – 566.375 MHz or
655.500–680.375 MHz the system shall be capable of operating on any
of 996 PLL-synthesized frequencies per band (adjustable in 25 kHz steps).
The frequency-agile FM wireless body-pack transmitter shall have
microphone and line level inputs. Connections shall be via a recessed
4-pin locking connector. It shall provide DC voltage to power microphones
requiring DC bias. The body-pack transmitter shall have a reversible clip
allowing for up or down cable entry. A dual color LED indicator shall
illuminate “green” when the transmitter is turned on and “red” when
the transmitter is muted. The transmitter shall have an audio input level
adjustment range of 24 dB. All adjustments shall be via soft-touch controls and shall remain as set even if the transmitter loses power or the
batteries are removed. A sliding door shall cover the setup controls when
not in use. The transmitter shall operate on two AA batteries and contain
a Hi/Lo power selector. The transmitter shall be equipped with a backlit
LCD screen used to show operating frequency and programming status.
A battery fuel gauge shall be incorporated into the display to indicate
the status of the internal batteries. The transmitter housing shall be of
high-impact materials with a captive battery door. The transmitter antenna
shall be removable and eld replaceable.
The wireless body-pack transmitter shall be an Audio-Technica
ATW-T1801 or equivalent.
