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. CAUTION! Electrical shock can result from removal of the receiver cover. Refer servicing to qualified service personnel. No user-serviceable parts inside. Do not expose to rain or moisture. The circuits inside the receiver and transmitter have been precisely adjusted for optimum performance and compli- ance with federal regulations. Do not attempt to open the receiver or transmitter. To do so will void the warranty, and may cause improper operation. Individuals with implanted cardiac pacemakers or AICD devices: Please see notice on back cover. Introduction Thank you for choosing an Audio-Technica professional wireless system. You have joined thousands of other satisfied customers who have chosen our products because of their quality, perfor- mance and reliability. This Audio-Technica wireless microphone system is the successful result of years of design and manufacturing experience. This professional wireless system includes a receiver and either a body-pack or a handheld transmitter on a specific crystal-controlled frequency. The receiver features true diversity reception. Two antennas feed two completely independent RF sections on the same frequency; automatic logic circuitry continuously compares and selects the superior received signal, providing better sound quality and reducing the possibility of interference and dropouts. The receiver is made to be mounted in a standard 190 rack (1 U). The versatile UniPakJ” body-pack transmitter has both low- and high-impedance inputs plus a bias connection, for use with dynamic and electret condenser microphones, as well as Hi-Z instrument pickups. Both the handheld and UniPak transmitters use internal 9-volt batteries and have Off/Standby/On switches, battery condition indicators, and battery-save switches. Please note that in multiple-system applications there must be a transmitter-receiver combination on a separate frequency for each input desired (only one transmitter for each receiver). Because the wireless frequencies are in or near VHF TV frequencies, only certain frequencies are useable in a particular geographical area. Also, only certain of the available operating frequencies may be used together. (Frequency selection information will be found on page 7.) 2 Receiver Installation Location For best operation the receiver should be at least 3 ft. above the ground and at least 3 ft. away from a wall or metal sur- face to minimize reflections. The transmitter should also be at least 3 ft. away from the receiver, as shown in Figure A. Fig. A Receiver Location Keep antennas away from noise sources such as motors, automobiles, and neon lights, as well as large metal objects. Output Connections There are two audio outputs on the back of the receiver: balanced (220 mV) and unbalanced (350 mV). Use shielded audio cable for the connection between the receiver and the mixer. If the input of the mixer is a 1/4″ jack, connect a cable from the 1/4″ unbalanced audio output on the back of the receiver to the mixer. If the input of the mixer is an XLR-type input, connect a cable from the balanced XLR-type audio output on the back of the receiver to the mixer. The two isolated audio outputs permit simultaneous feeds to both unbalanced and balanced inputs. For example, both a guitar amp and a mixer can be driven by the receiver. Antennas Assemble the two whip antennas to the special connectors provided. Screw the whips into the threaded side holes at the rear of the connector (Fig. B). Attach the antennas to the antenna input jacks. The antennas are normally positioned in the shape of a “V” (450 from vertical) for best reception. Do not try to move the antenna rod after the connector shell has been tightened down. Always loosen the connector shell completely before repositioning the rod. ANT. A Fig. B Antenna Assembly If there is not sufficient space above the receiver and/or if the receiver is installed in a metal cabinet, the antennas can be mounted in the threaded holes in the back of the connectors so the antennas will stick straight out from the back of the receiver. Use one set of threaded holes or the other; do not attempt to bend the antenna rods. (The optional accessory ATW-RAI rack-mount antenna kit brings antenna inputs to the front of the receiver.) Power Connections Connect the included AD1205A AC adapter to the DC power input on the back of the receiver. Then plug the adapter into a standard 120 volt 60 Hz AC power outlet.

Available frequencies are shown in the chart below. Operating frequency is specified by a two- or three-character code, such as "T 2" or "11 G," in addition to the actual frequency in MHz. The frequency of each transmitter appears on a label on the outside of the unit. The frequency of each receiver appears on a label on the back of the unit and the frequency of each system appears on the outer carton. For future reference, please record them in the space provided. Because most of these authorized frequencies are shared with TV broadcasting, frequency selection is largely dependent upon which TV broadcast channels are in operation where the wireless system is to be used. RF Interference If you encounter receiving interference (from other than an operating TV station), often it can be eliminated by adjusting the receiver's squelch control, as described on page 5. 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 within the band. If any interference is received by any Government or non-Government operation, the wireless microphone must cease operation.. If you need assistance with operation or frequency selection, please contact your dealer or the A-T professional division. Extensive wireless information also is available on the A-T Web site at audio-technica.com.

(AT-US,) to be free of defects in materials and workmanship. In event of such defect, product will be repaired promptly without charge or, at our option, replaced with a new product of equal or superior value if delivered to A.T.U.S. or an Authorized Service Center, prepaid, together with the sales slip or other proof of purchase date. Prior approval from A.T.U.S. is required for return. This warranty excludes defects due to normal wear, abuse, shipping damage, or failure to use product in accordance with the instructions. This warranty is void in the event of unauthorized repair or modification, or removal or defacing of the product labeling. For return approval and shipping information, contact the Service Dept., Audio-Technica U.S„ Inc., 1221 Commerce Drive, Stow, Ohio 44224. Except to the extent precluded by applicable state law, A.T.U.S. will have no liability for any consequential, incidental, or special damages; any warranty of merchantability or fitness for particular purpose expires when this warranty expires. This warranty gives you specific legal rights, and you may have other rights which vary from state to state. Outside the U.S.A., please contact your local dealer for warranty details. 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 wire- less 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. audio•technica Audio-Technica U.S., Inc., 1 221 Commerce Drive, Stow, Ohio 44224 330/686-2600 audio-technica.com P50901-Ol-B/W 01998 Audio-Technica Inc.
