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. Changes or modifications not expressly approved by Audio-Technica could void your authority to operate this equipment.

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 difficulty, 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.

CAUTION! 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.

Warning: To prevent fire or shock hazard, do not expose this appliance to rain or moisture. Attention: Pour prévenir feu ou choc électrique, ne pas exposé l'appareil à la pluie ou à l'humidité.

About 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 help with operation or frequency selection, please contact your local dealer or Audio-Technica. Extensive wireless information also is available at www.audio-technica.com.

System Features (dual-channel)

• Two completely independent receiver channels in a single unit, for simultaneous operation of two microphones

• True Diversity operation for resistance to multi-path interference and dropouts

• UHF reception with 996 frequencies selectable in 25 kHz steps

• Automatic frequency scanning for easy selection of open channels

• Tone Lock™ squelch system eliminates interference when transmitter is off

• Two independent balanced outputs

• Headphone monitor output with independent level control

• Battery fuel-level indicators on transmitters and receiver

• Soft-touch controls for easy frequency selection

• LCD frequency and battery status display with backlight on receiver and transmitters

• Antenna and AF Peak LED indicators

• Dual-channel receiver can operate in single-receiver mode to extend battery life when only one audio channel is required

• Compact dual receiver is easy to mount on a camera

• Transmitters operate in low or high transmission modes to conserve battery life/maximize power

• Easy, user-friendly operation

• Clear, natural sound quality

• Powered by AA batteries or by external 12V DC power (not included)

• System components of the 1800 Series and 3000 Series UHF wireless systems can be used interchangeably*

* NOTE: The 1800 Series offers operating frequencies in 25 kHz steps, while the 3000 Series offers operating frequencies in 125 kHz steps. This means that not every frequency selectable on the 1800 Series components will be selectable on the 3000 Series components. Set each transmitter-receiver pair to identical frequencies.

Quick Overview of System Operation

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 ATW-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 ATW-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 ATW-R1820 dual-channel receiver to your camera (mounting hardware not included); or use the included pouch with belt clip to attach the ATW-R1820 to your belt. Connect the output cable(s) to the ATW-R1820 and your video camera (and/or audio mixer). (See Output A, Output B, and Output Select Switch, page 7.)

Turn the ATW-R1820 Power Switch on. Choose “1” to activate only Receiver Channel 1 and Output A (Power/Peak LED 1 should light red); this option will increase useable battery life. Choose “Both” to activate both receiver channels and both outputs (Power/Peak LEDs 1 and 2 should light red). (See Power Switch with four positions: External, Off, 1, Both, page 6.)

Select a frequency for Receiver Channel 1 and Receiver Channel 2. (See Selecting Frequencies on your Receiver, page 8.)

NOTE: 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; set Transmitter 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 Microphone 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.)
