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.

RF Interference

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 in 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 Audio-Technica. Extensive wireless information also is available at www.audio-technica.com.

This Audio-Technica wireless microphone system is the successful result of years of design and manufacturing experience.

Each 2000 Series wireless system provides a choice of 10 PLL synthesized UHF frequencies in one of five UHF frequency ranges, available for flexible performance in a wide variety of regions worldwide:

Frequency Range

Band D 656.125 – 678.500 MHz

Band E 800.550 – 813.150 MHz

Band F 854.900 – 864.900 MHz

Band G 722.125 – 744.500 MHz

Band I 487.125 – 506.500 MHz

The band letter reference at the end of 2000 Series Stock Numbers indicates what band system/component operates in. For simplicity, model numbers used throughout this manual will reference only the basic model number without the band indications.

Each wireless system includes a receiver and either a body-pack or handheld transmitter. UniPak® body-pack transmitter systems include accessory microphones for particular applications. All A-T Wireless Essentials® microphones and cables, available separately, are preterminated for use with any Audio-Technica 2000 Series wireless system.

The ATW-R2100a 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 also offers a switchable output attenuator to reduce the level of the output signal by 12 dB for flexible use with a variety of system configurations. Switchable antenna power is also provided. Soft-touch controls provide convenient access to selection of operating frequency and automatic scanning, while an LCD information display provides constant

monitoring of system operation. The receiver is half-width for a standard 1U 19" rack mount; rack-mount adapters are included. Two receivers can be mounted side by side, using an optional AT8630 joining-plate kit.

The versatile ATW-T210a UniPak® body-pack transmitter has both lowand high-impedance inputs plus a bias connection, for use with dynamic and electret condenser microphones, as well as Hi-Z

instrument pickups. The UniPak® transmitter also offers separate trim controls for instrument and microphone, plus switchable high/low RF power.

The ATW-T220a handheld dynamic microphone/transmitter features the same element used in the PRO 41 dynamic handheld microphone created for professional live-sound venues. It also offers switchable high/low RF power. Both the ATW-T210a UniPak® and ATW-T220a handheld transmitters also offer charging contacts so the units can be placed in an optional recharging station for multi-transmitter charging.

For economical operation and wide availability, transmitters in the 2000 Series use two 1.5V AA alkaline batteries or rechargeable two AA NiMH batteries for use with Audio-Technica’s ATW-CHG2 Recharging

Station. Both transmitters have battery condition indicators. 2000 Series receivers feature a sophisticated Tone Lock™ tone squelch system that opens the receiver’s audio output only when a 2000 Series transmitter is detected, reducing the possibility of interference. As a result, 2000

2000 Series Installation and Operation

Series transmitters and receivers must be used together and should not be used with components from other Audio-Technica wireless systems, or with those of other manufacturers.

Please note that in multiple-system applications there must be a transmitter-receiver combination set to a separate channel (frequency) for each input desired (only one transmitter for each receiver).

Because the wireless frequencies are within UHF TV frequency bands, only certain channels (operating frequencies) may be useable in a particular geographic area. The 10 channels (operating frequencies) per band that are used in the 2000 Series have been selected for multichannel compatibility. Subject to frequency availability in a particular geographic area, any of these 10 channels may be used together. The operating frequencies that correspond to each of the 10 channels are listed on page 10.

Receiver Installation

Location

For best operation the receiver should be at least 3 ft. (1 m) above the ground and at least 3 ft. away from a wall or metal surface to minimize reflections. The transmitter should be at least 3 ft. from the receiver, as shown in Figure A. Keep antennas away from noise sources such as digital equipment, motors, automobiles and neon lights, as well as away from large metal objects.

Fig. A

Output Connections

There are two audio outputs on the back panel: balanced and unbalanced. 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 housing 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 panel 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

Attach the included pair of UHF antennas to the antenna input jacks. The antennas are normally positioned in the shape of a “V” (both 45° from vertical) for best reception.

Accessory antennas can be remotely located from the receiver. However, due to signal loss in cables at UHF frequencies, use the lowest-loss RF cables practical for any cable runs over 25 feet. RG8type is a good choice. Use only copper-shielded cable, not CATV-type foil-shielded wire. Audio-Technica offers quality RF cables in four lengths, as well as remote antennas; see audio-technica.com for a wide selection of wireless system accessories.

Antenna Power

The antenna input jacks also can provide +12V DC output on their center pins to power inline RF devices. A maximum of 60 mA can be drawn from each of the jacks. While an accidental short-circuit will not harm the internal 12V supply, make certain that an antenna cable shield does not contact the center conductor. Antenna Power is selected by

a switch on the back of the ATW-R2100a Receiver. The unit is shipped with the switch in the “off” position.

Note: the antennas included with the ATW-R2100a Receiver do not require power. If you have an antenna system that requires power (such as powered antennas or active combiners or splitters) switch the Antenna Power switch to the “on” position.

Power Connections

Connect the included AC adapter to the DC power input on the back of the receiver. Loop the small cord from the DC plug over the cord hook above the jack, to keep the plug from being detached by an accidental tug on the cord. Operation of the receiver is controlled by the frontpanel Power switch.
