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 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 half-width for a standard 19" (1U) rack mount. Please note that in multiple-system applications there must be a transmitter-receiver combination on a separatefrequency for each input desired (only one transmitter for each receiver). Operating frequency information will be found on page 6. The versatile ATW-T201 UniPak body-pack transmitter has both a high-impedance input for instruments, and a low-impedance input with bias connection for use with dynamic and electret condenser microphones. The ATW-T202 handheld transmitter features a unidirectional dynamic microphone element. Both the body-pack and handheld transmitters use internal 9-volt batteries and have Off/Standby/On switches, input Trim (level) adjustments and battery-save switches. Introduction See pages 8-9 for illustrations. Notice to individuals with implanted cardiac pacemakers or AICD devices: Any source of RF (radio frequency) energy mayinterfere 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, especial- ly 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. Receiver Installation 3 Location For best operation the receiver should be at least 3' (1 m) above the ground and at least 3' (1 m) away from a wall or metal surface to minimize reflections. Keep the receiver antennas away from noise sources such as digital equipment, motors, automobiles and neon lights, as well as away from large metal objects. In multi-channel systems, position receivers at least 3' (1 m) apart and keep operating transmit- ters at least 6' (2 m) from the receivers to help assure maximum RF performance. Output Connection There are two audio outputs on the back of the receiver: balanced (160 mV) and unbalanced (280 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.

RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-2001 using a HEWLETT PACKARD spectrum analyzer with a 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 100KHZ and the video bandwidth was 300KHZ. 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 = FS 33 20 dBuV + 10.36 dB = 30.36 dBuV/m @ 3m ANSI STANDARD C63.4-2001 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 ANSIC63.4-1992 with the EUT 40 cm from the vertical ground wall.
