Quick verview of System peration
Thank you for purchasing this Audio-Technica 1800 Series Dual-channel Camera-mount
UHF Wireless Microphone System. All 1800 Series systems are designed primarily to be used
with video cameras, with the AT W-R1820 dual-channel receiver mounted on a camera and
connected to the camera's audio input; the systems may also be used with other components
equipped with microphone-level input(s).
This system is equipped with a dual receiver, which consists of two completely independent
receiver channels in a single unit, for simultaneous operation of two microphones.
First, insert batteries (see Battery Installation, page 8 ). Note: The AT W-R1820 dual-channel
receiver also functions without batteries if connected to an external power supply
(12V DC source, 500 mA nominal current, not included).
Next, attach the antennas to the antenna input jacks, and mount the AT W-R1820 dual-channel
receiver to your camera (mounting hardware not included); or use the included pouch with belt
clip to attach the AT W-R1820 to your belt. Connect the output cable(s) to the AT W-R1820 and
your video camera (and/or audio mixer). (See Output A, Output B, and Output Sele t Swit h,
page 7.)
Turn the AT W-R1820 Power Switch on. Choose “1” to activate only Receiver Channel 1 and
Output A (Power/Peak LE 1 should light red); this option will increase useable battery life.
Choose “Both” to activate both receiver channels and both outputs (Power/Peak LE s 1 and 2
should light red). (See Power Swit h with four positions: External, Off, 1, Both, page 6.)
Select a frequency for Receiver Channel 1 and Receiver Channel 2. (See Sele ting Frequen ies
on your Re eiver, page 8.)
N TE: Receiver Channel 1 and Receiver Channel 2 must be set to different frequencies to
avoid interference. Transmitter-Receiver pairs must be set to identical frequencies: set
Transmitter 1 to the same frequency as Receiver Channel 1; setTransmitter 2 to the same
frequency as Receiver Channel 2.
If your system is equipped with a UniPak®Body-pack Transmitter and lavalier microphone:
Plug the included lavalier microphone(s) into the UniPak®body-pack transmitter(s) and position
microphone(s) on your subject about six inches below the chin. Anticipate movements that may
cause the microphone to rub against or be covered by clothing, and position the microphone to
avoid it. Turn the power on, select a frequency and choose other settings. (See Operating the
Transmitter, page 12.)
If your system is equipped with a Plug-on Transmitter:
Attach a microphone (dynamic or condenser) to the plug-on transmitter’s input connector
(see Mi rophone Input, page 11). The transmitter provides power to condenser microphones
rated to operate on 12V phantom power or less. Turn the power on, select a frequency and
choose other settings. (See Operating the Transmitter, page 12.)

AT W-R1820 Dual-channel Receiver Controls (front panel)
Liquid Crystal isplay shows battery status and frequency settings. (Use the ual-channel
Control Switch (6) to select frequencies for Receiver Channel 1 and Receiver Channel 2;
in Hold position, only Receiver Channel 1 frequency appears in LC .) Battery meter is only
active when ual-channel Control Switch is in the Hold position.
BNC-type antenna connectors. Antennas A & B (split internally) both provide signals for
Receiver Channel 1 and Receiver Channel 2. Attach the antennas to the antenna input jacks.
Make certain that during operation there is a clear open-air path between the receiver antennas
and the transmitters.
True iversity operation: two antennas feed two completely independent RF sections on the
same frequency for each receiver; automatic logic circuitry selects the superior signal.
iversity Indicator 1 indicates which tuner has the better reception and is in operation for
Receiver Channel 1; iversity Indicator 2 indicates which tuner has the better reception and is
in operation for Receiver Channel 2.
Turns the unit on and off.
Choose “Ext”, if the unit is connected to an external power supply (12V C source, 500 mA
nominal current, not included). In “Ext” position, both receiver channels and both outputs are
activated (indicated by illumination of Power/Peak LE s 1 and 2).
Choose “Off” to turn the unit off.
Choose “1” to activate only a single receiver channel (Receiver Channel 1/Output A, indicated by the
illumination of Power/Peak LE 1). This conserves energy if you are only using one audio channel.
Choose “Both” to activate both receiver channels and both outputs (indicated by illumination of
Power/Peak LE s 1 and 2).
Note: Selected receiver will be muted unless Dual-channel Control Switch (6) is in Hold position.
Indicates which receiver channel(s) is (are) in operation. Also indicates receiver overload by
turning off; too much signal will cause blinking LE (off during peaks). To correct overload,
adjust audio gain on transmitter. (See Audio Input Level (Gain) Adjustments, page 13.)
This switch allows you to use the single LC window to control each of the two receiver
channels separately.
To set frequency for Receiver Channel 1, switch to 1 (left position).
To set frequency for Receiver Channel 2, switch to 2 (right position).
To lock settings and operate unit, switch to Hold (center position).
Note: Receiver Channel 1 is muted when switch is at 1; Receiver Channel 2 is muted
when switch is at 2; both channels un-mute when switch is at Hold.
This LE is red when switch is in position 1, indicating muted operation for Receiver Channel 1.
It is also red when switch is in position 2, indicating muted operation for Receiver Channel 2.
LE turns green in Hold position, indicating unit is ready for operation.
Use with the ual-channel Control Switch and Up/ own arrows to choose operating frequencies
manually or automatically (using your choice of three automatic scan groups).

Pin 3: “audio -”. Use the included TA3F to XLRM interface cable to connect the receiver output
to a balanced microphone-level input on a camera, mixer or integrated amplifier.
The rear panel provides two balanced audio outputs (Outputs A & B). The unit is equipped with
an output select switch that assigns a signal to each of the audio outputs, as follows:
Output A (left) can be assigned either Receiver Channel 1 or Mix. (Mix = Ch. 1 and Ch. 2
signals mixed together. The relative levels of each signal can be adjusted using the individual
receiver level controls.)
Output B (right) can be assigned either Receiver Channel 1, Receiver Channel 2, or Mix.
Note: utput B is not active when Power Switch is in “1” position.
Typical configuration: Output A is assigned Channel 1; Output B is assigned Channel 2, feeding
individual channels in a mixer or camera. Many other options are available, providing much
flexibility. For instance:
• If your camera doesn’t accept two inputs, you can sum the signal from both transmitters
in Output A and connect this mixed signal to your camera.
• You can connect Output A (mixed signal) to a camera, and Output B (mixed signal)
to an audio mixer.
• When using the unit with a single transmitter with both outputs active (Power Switch set
at Both), Output A can be used to feed a camera, while Output B can feed an audio mixer
(both with identical signals from Receiver Channel 1).
The signal levels of each receiver signal (Receiver Channel 1 and Receiver Channel 2) may
be adjusted using these controls. When the outputs are assigned to a single receiver signal,
these controls will adjust the output level. (Turn clockwise to increase output level.) When the
outputs are assigned to Mix, these controls adjust the relative levels between the
receiver signals.
This switch assigns a signal to the monitor headphone output.
• Choose 1(left position) to hear Channel 1 in both ears (mono signal, stereo output);
• Choose 2(right position) to hear Channel 2 in both ears (mono signal, stereo output);
• Choose UT (middle position), to hear Output A in the left ear, and Output B in the right ear.
The level control (volume control) for headphones is independent of other level controls.
Turn to the right to increase the volume.
You may connect the unit to an external power supply (12V C source, 500 mA nominal
current, not included). In this case, move the Power Switch to the “Ext” position; both receiver
channels are activated (indicated by illumination of Power/Peak LE s 1 and 2).

AT W-R1820 Dual-channel Receiver Batteries
Each AT W-R18 20 dual-channel receiver uses six 1.5V AA batteries, not included. Alkaline type is
recommended. Always replace all batteries. Make certain the receiver power is Off before
replacing batteries. Note:The AT W-R18 20 receiver also functions without batteries if connected
to an external power supply (12V DC source, 500 mA nominal current, not included).
1. Open the battery compartment door by pushing the catch back.
2. Observe correct polarity as marked and carefully insert six fresh 1.5V AA alkaline batteries
(see above).
3. Replace the door, making certain the latch clicks securely in place.
After the batteries are installed, turn the power on by moving the Power Switch to either the 1
or Both position. The small red power- on LE (s) (see aat left ) should light (red light at 1 if Power
Switch is in position 1; red light at 1 and 2 if Power Switch is in Both position) and the LC window
should come on. If this does not happen, the batteries are installed incorrectly or they are depleted.
The receiver’s “fuel gauge” battery indicator (see bat left ) displays a maximum of four bar
segments. When LC flashes “LOW.BAT”, the batteries should be replaced immediately to
ensure continued operation. Note: Battery indicator is only visible in the “Hold” position.
