1800 Series (Dual-Channel) Owners Manual 1800 Series Camera-mount UHF Wireless Microphone Systems (dual-channel) ATW-1821 Body-pack Transmitters System ATW-1822 Plug-on Transmitters System ATW-1823 Plug-on and Body-pack Transmitters System Installation and Operation 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. 1800 Series System Components (Dual-Channel) All 1800 Series dual-channel systems include: ATW-R1820 Dual-channel receiver Two detachable antennas Two 18” output cables, TA3F to XLRM Pouch with belt clip (holds receiver) Hook & loop fastener mount Each of the three dual-channel camera-mount wireless systems also includes the following: ATW-1821 Camera-mount UHF Wireless Microphone System (dual-channel) with Body-pack Transmitters Two ATW-T1801 UniPak™ Body-pack Transmitters Two Omnidirectional Lavalier Microphones ATW-1822 Camera-mount UHF Wireless Microphone System (dual-channel) with Plug-on Transmitters Two ATW-T1802 Plug-on Transmitters ATW-1823 Camera-mount UHF Wireless Microphone System (dual-channel) with Plug-on and Body-pack Transmitters ATW-T1801 UniPak™ Body-pack Transmitter ATW-T1802 Plug-on Transmitter Omnidirectional Lavalier Microphone System Features (Dual-Channel) • Two completely independent receiver channels in a single unit, for simultaneous operation of two microphones • Extremely compact receiver is easy to mount on a camera with included Velcro-type fastener • 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 (Transmitters are compatible with Advanced Digital Tone Lock™ squelch on Audio-Technica’s 3000 Series UHF Wireless Systems) • Two independent balanced outputs (you can assign function of each, independently) • Headphone monitor output with independent level control • Battery fuel-level indicators on transmitters and receiver • Soft-touch controls for easy frequency selection • True Diversity operation for resistance to multi-path interference and dropouts • LCD frequency and battery status display with backlight • Antenna and AF Peak LED indicators • Easy, user-friendly operation • Clear, natural sound quality • Powered by AA batteries 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; they 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 Receiver Battery Installation, page __.) 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, mount the ATW-R1820 Dual-channel Receiver to your camera using the included hook & loop fastener mount or another accessory bracket (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 callouts, page ___). Turn the ATW-R1820 Power Switch on. Choose “1” to activate only Receiver Channel 1 (power/peak LED 1 should light red); this option will increase useable battery life. Choose “Both” to activate both receiver channels (power/peak LEDs 1 and 2 should light red). (See Power Switch with four positions: External, Off, 1, Both callout, page ___.) Select a frequency for Receiver Channel 1 and Receiver Channel 2. (See Selecting Frequencies on your Dual-channel Receiver, page ___.) 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…

RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-2003 using a spectrum analyzer with pre-selector. The bandwidth of the spectrum analyzer was 100 kHz with an appropriate sweep speed. The analyzer was calibrated in dB above a microvolt at the output of the antenna. The resolution bandwidth was 100 kHz and the video bandwidth was 300 kHz. The ambient temperature of the UUT was 80ºF with a humidity of 70%. FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was established by adding the meter reading of the spectrum analyzer (which is set to read in units of dBuV) to the antenna correction factor supplied by the antenna manufacturer. The antenna correction factors are stated in terms of dB. The gain of the Preselector was accounted for in the Spectrum Analyzer Meter Reading. Example: Freq (MHz) METER READING + ACF +Coax Loss = FS 33 20 dBuV + 10.36 dB +1.2 = 31.66 dBuV/m @ 3m ANSI STANDARD C63.4-2003 10.1.7 MEASUREMENT PROCEDURES: The unit under test was placed on a table 80 cm high and with dimensions of 1m by 1.5m. The table used for radiated measurements is capable of continuous rotation. When an emission was found, the table was rotated to produce the maximum signal strength. At this point, the antenna was raised and lowered from 1m to 4m. The antenna was placed in both the horizontal and vertical planes. The situation was similar for the conducted measurement except that the table did not rotate. The EUT was setup as described in ANSI C63.4-2003 with the EUT 40 cm from the vertical ground wall.
