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…

Operational Description of ATW-T1801D Transmitter 1. Audio 1.1 Audio signal produced by the Microphone element is feed in to the audio IC 200. 1.2 Audio signal injected in to the IC200 is then amplified by the internal AF Amp. 1.3 Amplified audio signal is feed in to the compander circuit that const by IC250 operational amp and IC251compander IC, and compressed. 1.4 Audio signal that coming from the Guitar cable also feed in to the IC200, through the buffer amplifier, then feed in to the same AF amp listed item 1.2. 1.5 The compressed audio signal Is feed in to the IC200 and pre-emphasized and out from the IC200 and adjusted it level to appropriate by VR201. 1.6 32.15KHz signal that produced by the tone generator circuit in the IC200, is superposed with the control signal that produced by the micro-controller IC300 and out from the IC200 and adjusted it level to appropriate by VR200. 1.7 Properly adjusted Audio and tone signals are mixed and send to the VCO, VCO100. 1.8 Q280 detects peak signal level that feed in to the microphone and line input and dimmer the Power LED D349. 2. RF 1.9 RF signal produced by the VCO, VCO100 is modulate by the mixed audio and tone signal. 1.10 Modulated RF signal is through the buffer amp Q101, feed to the RF amplifier, consist by Q102 and Q103. 1.11 Amplified RF signal is then set it RF output power to; Hi position, 30mW by VR101and Low position, 10mW by VR100. 1.12 Amplified RF signal is suppress it harmonics by through Low pass filter consist by L104 to 108, C132 to 136 and feed in to Antenna terminal. 1.13 RF signal feed in to the Antenna terminal is then transmitted to the air by antenna screwed on to it.

RF power measured is: HIGH: O.030 WATTS ERP LOW: 0.015 WATTS ERP For a device with a fixed antenna, RF power is measured as ERP as the antenna is permanently attached. The substitution method was used as described in TIA-603-C. METHOD OF MEASUREMENT: The tabulated data shows the results of the radiated field strength emissions test. The spectrum was scanned from 30 MHz to at least the tenth harmonic of the fundamental. This test was conducted per TIA/EIA STANDARD 603 using the substitution method. Measurements were made at the test site of TIMCO ENGINEERING, INC. located at 849 NW State Road 45, Newberry, FL 32669. TIMCO ENGINEERING INC.

From 100 to 250% of the authorize3d band- width they are attenuated by at least 35dB and beyond 250% 43 log(Po) dB. The plot shows the transmitter modulated with 15000 Hz(the highest modulation frequen- cy), adjusted for 50% modulation plus 16 dB.
