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-R1820dual-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.)
