Set each transmitter-receiver pair to identical frequencies. 5 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.) 6 ATW-R1820 Dual-channel Receiver Controls (front panel) LCD 1 Liquid Crystal Display shows battery status and frequency settings. (Use the Dual-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 LCD.) Battery meter is only active when Dual-channel Control Switch is in the Hold position. Antenna Input Jacks 2 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. Diversity Indicators 3 True Diversity operation: two antennas feed two completely independent RF sections on the for each antenna same frequency for each receiver; automatic logic circuitry selects the superior signal. for each receiver Diversity Indicator 1 indicates which tuner has the better reception and is in operation for Receiver Channel 1; Diversity Indicator 2 indicates which tuner has the better reception and is in operation for Receiver Channel 2. Power Switch 4 Turns the unit on and off. with four positions: External, Off, 1, Both Choose “Ext”, if the unit is connected to an external power supply (12V DC source, 500 mA nominal current, not included). In “Ext” position, both receiver channels and both outputs are activated (indicated by illumination of Power/Peak LEDs 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 LED 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 LEDs 1 and 2). Note: Selected receiver will be muted unless Dual-channel Control Switch (6) is in Hold position. Power/Peak LED 5 Indicates which receiver channel(s) is (are) in operation. Also indicates receiver overload by turning off; too much signal will cause blinking LED (off during peaks). To correct overload, adjust audio gain on transmitter. (See Audio Input Level (Gain) Adjustments, page 13.) Dual-channel Control Switch 6 This switch allows you to use the single LCD window to control each of the two receiver channels separately. with three positions: 1, Hold, 2 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. Dual-channel Control LED 7 This LED 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. LED turns green in Hold position, indicating unit is ready for operation. Set 8 Use with the Dual-channel Control Switch and Up/Down arrows to choose operating frequencies manually or automatically (using your choice of three automatic scan groups).

Pin 1: ground (shield); Pin 2: “audio +”; 10 Output A 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. PIN 1 Balanced Audio Output Jack: TA3M-type connector. Pin 1: ground (shield); Pin 2: “audio +”; 11 Output B 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. PIN 3 PIN 2 The rear panel provides two balanced audio outputs (Outputs A & B). The unit is equipped with 12 Output Select Switch 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: Output 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 13 Receiver Level Controls (1 and 2) 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. 14 Monitor Select Switch • 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 OUT (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. 15 Monitor Level Control Turn to the right to increase the volume. You may connect the unit to an external power supply (12V DC source, 500 mA nominal 16 DC Input current, not included).

The word “MUTE” will appear in the LCD window, just below the frequency, and the Power-on LED will turn red. To un-mute the transmitter (restore the audio), press and release the Power/Mute button once again. The “MUTE” will disappear from the LCD window, and the Power-on LED will turn green. The Power/Mute button can be programmed (through the function menu): power can be locked Power/Mute Locks On; Mute can be locked either On or Off. Setting Description NO.LOC The Power and Mute functions operate normally. ALL.LOC Both the Power and Mute functions are locked into their status as of the time “ALL.LOC” is applied. (Power On, and Mute either On or Off.) Note: “ALL.LOC” must be re-accessed and the setting changed to turn the transmitter off. MUT.LOC In “MUT.LOC” mode, the audio cannot be muted. The Power functioning is unaffected. (If “MUT.LOC” is applied while the transmitter is muted, pressing the Power/Mute button once will return to un-muted operation; thereafter the Mute function is disabled until the setting is changed again.) PWR.LOC Power is locked On as of the time “PWR.LOC”is applied. The Mute functioning is unaffected. Note: When in the “PWR.LOC” mode, the transmitter may be turned off by: (1) Re-accessing the .LOC Menu and changing the setting, or (2) Removing and re-installing the batteries. When the transmitter is turned on again, it will power-up in the “NO.LOC” mode. (Only the “PWR.LOC” function will change when batteries are removed; all other settings remain stored in memory.) If an attempt is made to take an action that currently is locked out, the LCD will display “LOC.KED” briefly, then return to its previously-displayed contents. The UniPak® body-pack transmitter provides input connections for both low-impedance (Lo-Z) Audio Input Selector microphones and high-impedance (Hi-Z) instruments. A wide range of Audio-Technica Wireless Essentials™ microphones and cables are available pre-terminated with the appropriate professional latching connector (see page 14 ). Select the desired input – microphone or instrument – through the function menu; “MIC” or “INST” will show in the LCD window, just below the frequency. (continued on page 14) 14 Operating the Transmitter (continued) Restore Default Settings 1. A “PRESET” selection in the menu allows you to reset all transmitter functions to their factory-default values. 2. Press the Set button once to move to Menu mode. 3. Press the Up arrow twice to move to “PRESET” in the LCD window. 4. Press the Set button once and “LOAD” will appear in the LCD. 5. Press and hold the Set button until “DEF” appears in the LCD. 6. Press and hold the Set button until “LOADED” appears briefly in the LCD. The window will then revert to “PRESET”. 7. Press the Down arrow once to move to “QUIT”. 8. Press the Set button once to exit the Menu mode and return to normal operation, with all factory-default settings restored. Tips for Best Results 1. Use only fresh alkaline batteries. Always replace all batteries. Do not use “general purpose” (carbon-zinc) batteries. 2. Position the dual-channel receiver so that it has the fewest possible obstructions between it and the normal location of the transmitters. Line-of-sight is best. 3. The transmitters and the dual-channel receiver should be as close together as conveniently possible, but no closer together than three feet. 4. The receiver antennas should be in the open and away from any metal. 5. Each transmitter-receiver pair must be set to the same frequency. 6. Only one transmitter on a given frequency should be “on” at a time. 7. The power switch on the transmitter has four positions: “Ext.,” “Off”, “1” and “Both.” 8. If the “Out Level” of either receiver channel is set too high, it may over-drive the input of the camera/mixer or clip the output of the receiver, causing distortion. Conversely, if the receiver output is set too low, the overall signal-to-noise ratio of the system may be reduced. 9. You need to change channels 1) when a strong interference signal is received, 2) when the channel breaks down, or 3) during multiple-system operation in order to select an interferencefree channel. Always turn the units off before changing frequencies. 10. Turn the receiver and transmitter off when not in use. Remove the batteries during long-term storage.
