2000 Series Professional UHF Wireless Systems ATW-2110 UniPak Transmitter System ATW-2120 Handheld Dynamic Microphone System Installation and Operation

()audio-technica. Professional UHF Wireless Systems 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 conformit 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. Notice to individuals with implanted cardiac pacemakers or AICD devices:

Any source of RF (radio frequency) energy may interfere with norma! 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. 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, performance and reliability. 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 the 656-678 MHz band (TV channels 45-48). Each wireless system includes a receiver and either a body-pack or handheld transmitter. Individual components are also available separately. The ATW-R2100 rceiver 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. 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-T210 UniPak 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. The ATW-T220 handheld dynamic microphone/transmitter features the same element used in the PRO 41 dynamic handheld microphone created for professional live-sound venues. Transmitters in the 2000 Series use two 1.5V AA batteries for economical operation and wide availability. 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 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) that are used in the 2000 Series have been selected for multi-channel 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 11. eam EEL yee 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. Output Connections There are two audio outputs on the back panel: balanced

(12.5 mV) and unbalanced (25 mV). Use shielded audio cable for the connection between the receiver and the mixer. If the input of the mixer is a */4" jack, connect a cable from the 1."

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 XL.R-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. Figure A 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. RG8-type 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 the Optional System Accessories section on page 10. 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. Then plug the adapter into a standard 120 Volt 60 Hz AC power outlet. Operation of the receiver is controlled by the front-pane! Power switch.

(Note: Units supplied to countries with 230V mains should include an in-line AC adapter appropriate for that country. Use the included adapter only with 120V 60 Hz AC power sources.)

Screwdriver on opposite side Transmitter Door Handheld Transmitter Battery Installation 1. While holding the upper part of the transmitter body by the translucant ring below the ball-screen, unscrew the lower body cover, slide it downward, and remove it to expose the battery compartment. 2. Observe correct polarity as marked inside the battery compartment and carefully insert two fresh 1.5V AA alkaline batteries. Insert the first battery and slide it down. Then insert the second battery into the space remaining. Make certain the batteries are fully seated in the battery compartment. (Fig. F) 3. Slide the lower body cover back up the body, then screw the housing together. Do not overtighten. Note: Remove batteries from the handheld transmitter starting at the bottom end, where finger indents in the battery housing are provided for easy grip. Figure F-Handheld Transmitter Battery Compartment Screwdriver Battery Indicator After the battery is installed, turn on the power switch (located on the bottom of the handheld transmitter and on the top of the UniPak transmitter). The battery indicator LED (Fig. G/H) should turn red. If it does not, the batteries are installed incorrectly or they are dead. Figure G-UniPak Transmitter Top View Figure H-Handheld Transmitter Bottom View Battery Indicator Battery Indicator input Connector Power Switch Power Switch UniPak Transmitter Input Connection Connect an audio input device (microphone or guitar cable) to the audio input connector on the top of the transmitter. A number of Audio-Technica professional microphones and cables are available separately, pre-terminated with a UniPak input connector (see Optional System Accessories on page 10). UniPak Transmitter Antenna The ATW-T210 UHF transmitter includes one field-replaceable antenna mounted on the transmitter. The antenna simply screws into the transmitters antenna fitting. Check the installed antenna occasionally to make certain it is snugly attached (only finger-tight). If the received signal is marginal, experiment with different transmitter positions on your body or instrument or try repositioning the receiver. Do not attempt to modify the transmitting antenna. Replace it only with the same parts, available from the Audio-Technica Service Department. System Operation Switch on the receiver. Do not switch on the transmitter yet. Receiver On... The LCD display will light up and one of the tuner operation indicator LCD segments (A or B) will light, even though the transmitter is not on. If two or more of the RF LCD segments light up at this point, there may be FF interference in the area. If this occurs, change operating channels (select another frequency). How to Make Operating Channel Changes Operating channel changes (frequency changes) may be made in two ways: manually and automatically. To change channel manually 1. Use the Up/Down arrow buttons to reach the desired channel number. 2 Hold the Set/Scan button until the channel number stops flashing to set the receiver to the channel indicated. NOTE: Before the channel has been set, a touch

(momentary press) of the Set/Scan (rather than a hold) will revert the channel to its previous setting. To change channel automatically 1. Hold the Set/Scan button. The Automatic Scan/Set Mode will automatically scan for and set the next open channel. LCD screen will flash FS four times to indicate start of scan. Transmitter On... Before turning on the transmitter, use the provided screwdriver to set the transmitter channel selector switches (Fig. E/l) to the same numbers as those displayed on the receiver. Always turn the transmitter off when changing channels (frequencies). _ The transmitters have a two-position, on-off power switch. When the switch is On, the transmitter produces both RF and audio. There is about a half-second delay after the transmitter is switched to the On position before the receiver's Tone Lock squelch un-mutes the receiver. When the transmitter is switched on and in normal operation, the receiver's RF signal level indicators will display as dark segments (signal strength indicators) from bottom to top at the left side of the LCD display. Setting Levels Correct adjustment of transmitter audio input, receiver audio output, and mixer/amplifier input and output levels is important for optimum system performance. ATW-T220 Handheld Transmitter The 2000 Series -handheld transmitter has factory pre-set audio input levels. Factory setting is full clockwise, maximum gain. While speaking/singing into the microphone at typically loud levels, check the AF meter levels on the receiver. If all five AF meter bars are consistently illuminated and distortion is heard through the system, it may be necessary to adjust the transmitter audio input level. To adjust the transmitter audio input level, unscrew the lower body cover and slide it downwards, exposing the screwdriver and level trim control (Fig I). Remove the screwdriver and gently turn the level trim control counterclockwise until the topmost receiver AF level meter bar is iNuminated only on audio peaks. Return the screwdriver to its clip and close and secure the lower body. No further transmitter gain adjustments should be needed, as long as the acoustic input does not change significantly. CAUTION! The smail trimmer controls are delicate; use only the supplied screwdriver. Do not force the trimmers beyond their normal 180 range of rotation. Return the screwdriver to its storage clip when not in use. Figure |-Handheld Transmitter Interior View Level Trim Control Channel Selector Switch Screwdriver System Operation (continued) Setting Levels (Continued) ATW-T210 UniPak Transmitter Trimmer adjustments in the UniPak transmitter (Fig. E) will enable you to use microphones or instruments with different output levels. 1. For MIC: Set microphone level trim control fully clockwise (maximum) and instrument level trim control fully counterclockwise (minimum). For INSTRUMENT: Set instrument level trim control fully clockwise (maximum) and microphone level trim control fully counterclockwise (minimum). 2. Set the receiver's AF Level control to its full clockwise position (maximum). See Figure D on page 5. 3. Plug the mic or instrument into the transmitter and power up the system. 4. For MIC: Make an initial adjustment of the mixers level controls that will allow audio through the system. For INSTRUMENT: Make an initial adjustment of the instrument amplifier input level control that will allow audio through the system. 5. For MIC: While speaking/singing into the microphone at typically loud levels, check the AF meter levels on the receiver. If all five meter bars are consistently illuminated and distortion is heard through the system, it may be necessary to adjust the UniPak transmitter audio input level. To adjust the transmitter audio input level, gently turn the microphone level trim control counterclockwise until the topmost receiver AF level meter bar is illuminated only on audio peaks. For INSTRUMENT: While playing the instrument at typically loud levels, check the AF meter levels on the receiver. If all five meter bars are consistently illuminated and distortion is heard through the system, it may be necessary to adjust the UniPak transmitter audio input level. To adjust the transmitter audio input level, gently turn the instrument level trim control counterclockwise until the topmost receiver AF level meter bar is illuminated only on audio peaks. 6. For MIC: While again speaking/singing into the microphone at typically loud levels, adjust the mixers input trim control so the highest sound pressure level going into the micro-

phone causes no input overload in the mixer, and yet permits the mixers channel and output level controls to operate in their normal range (not set too high or too low). For INSTRUMENT: While again playing the instrument at typically foud levels, adjust the receivers AF Level control so the highest signal level causes no input overload in the instrument amplifier and yet permits the amplifiers input level controls to operate in their normal range (not set too high or too low). Note: If the mixer cannot be adjusted to operate in its normal range without distortion, adjust the receiver's AF Level Control (turn counterclockwise) until the mixer/

amplifier is no longer overloaded. Figure E-UniPak Transmitter Open Audio Input Jack Instrument/Microphone Channel Level Trim Controls Selector Battery-keeper Arm (open);

Screwdriver on opposite side Transmitter Door Receiver Squelch The squelch control on the back panel of the receiver is preset at the factory for best system performance (factory setting is full counterclockwise), but can be adjusted if you must use the system in an area with considerable RF interference. If there is interference in the audio, and changing the channel is not an option, adjust the squelch control so the system will receive the signal from your transmitter but will squelch or eliminate the unwanted background RF noise. This adjustment can cause a reduction in useable range of the wireless transmitter, so set the control to the lowest position that reliably mutes the unwanted RF signals. 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...

Do not use general purpose (carbon-zinc) batteries. Position the receiver so that it has the fewest possible obstructions between it and the normal location of the transmitter. Line-of-sight is best. The transmitter and the receiver should be as close together as conveniently possible, but no closer than three feet (1 m). The receiver antennas should be in the open and away from any metal. If mounted in a rack, have the unit on top, or use an ATW-RAT kit to front-mount the antennas. The transmitter and receiver must be set to the same channel number. A receiver cannot receive signals from two transmitters at the same time. 7. If the AF Level control of the receiver is set too high, it may over-drive the input of the mixer or clip the output of the receiver, causing distortion. Conversely, if the receiver output is set too low, the overall signal-to-noise ratio of the system may be reduced. Please see Setting Levels section, pages 7 and 8. You need to change channels when a strong interference signal is received (a strong RF signal is shown with the transmitter off). in the UniPak transmitter, the microphone level trim or instrument level trim input control not in use should be set to minimum. Turn the transmitter off when not in use. Remove the battery if the transmitter is not to be used for a period of time. , For future reference, please record your system information here.
