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.

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 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.

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

For simplicity, model numbers used throughout the manual will reference only the basic model number without the “C” or “D” band indications.

Each wireless system includes a receiver and either a bodypack or handheld transmitter. Individual components are also available separately.

All 3000 Series components feature soft-touch controls for quick, easy access to a formidable range of functions; an LCD information display in each unit provides convenient visual indication of unit settings and operation.

The ATW-R310 receiver features true diversity reception. Two antennas feed two completely independent RF sections on the same frequency; automatic logic circuitry continuously

es and selects the superior received signal, providing

compar better sound quality and reducing the possibility of interference and dropouts. Soft-touch controls provide convenient access to a variety of functions, while an LCD information display provides constant monitoring of system operation, including indication of the transmitter’s battery status. 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-T310 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. In addition to its programmable functions, the transmitter features a three-position sliding cover to limit access, if desired, to just the Power/Mute button, or to no controls, as appropriate for the application and user.

The ATW-T341 handheld dynamic microphone/transmitter features the same element used in the Artist Elite dynamic handheld microphone cr sound venues.

Transmitters in the 3000 Series use two 1.5V AA batteries for economical operation and wide availability. The receiver and both transmitters have “fuel gauge” battery condition indicators with low-batter

-R310 receiver opens only when a 3000 Series transmitter is detected, reducing the possibility of interference. As a result, 3000 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 ther a transmitter for each input desired (only one transmitter for each receiver).

Because the wireless frequencies are within UHF TV frequency bands, only certain operating frequencies may be useable in a particular geographic area. System operating frequencies will be found on page 12.

Receiver Installation

Location

For best operation the receiver should be at least 3 ft. (1 m) above the gr

face to minimize reflections. The transmitter should be at

sur least 3 ft. fr antennas away from noise sources such as digital equipment, motors, automobiles and neon lights, as well as away from large metal objects.

Output Connections

e are two audio outputs on the back panel: balanced

Ther (32 mV) and unbalanced (50 mV). Use shielded audio cable for the connection between the receiver and the mixer. If the input of the mixer is a 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

Antennas can be remotely located from the receiver. However, due to signal loss in cables at UHF fr 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 11.

Power Connections

Connect the included AD1205AA in-line 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 larger cord from the in-line adapter into a standard 120 Volt 60 Hz AC power outlet. Operation of the receiver is controlled by the front-panel Power switch.

(Note: Units supplied to countries with 230V mains should include an in-line AC adapter appropriate for that country.

Use the AD1205AA adapter only with 120V 60 Hz AC power sources.)

Power On/Off

To turn the receiver on, press in the Power switch. The Alert light and the LCD window will come on (about 1-2 seconds). The operating frequency will be displayed in the window after the power-up sequence. To turn the receiver off, press the Power switch again.

LCD Window

The LCD (Liquid Crystal Display) presents a great deal of setup and operating information clearly and conveniently. (See Figure D for examples.)

Up/Down Arrow Buttons

In conjunction with the Mode/Set button, the arrow buttons permit moving through the menu of functions, and choice of settings within each function.

Mode/Set Button

The Mode/Set button shifts the receiver from normal operation into Menu mode and, in conjunction with the Up/Down arrow buttons, permits selection of different features and changing of their stored values in the Edit mode.

How to Make Setting Changes

1. From the normal operating mode, press the Mode/Set button

once to enter the Function Menu mode. (Only the

frequency will remain in the LCD window, and the receiver’s audio output will be cut off.)

2. Use the Up/Down arrow buttons to reach the desired function. The value in the LCD window is the current setting for that function.

3. Press the Mode/Set button once again to open the list of available choices for that function. The value will flash, indicating that it can be changed (Edit mode).

4. Use the arrow buttons to go through the available choices, stopping on the desired new choice.

Receiver Controls and Functions (Continued)

When the receiver is in the Menu or Edit mode, its audio output is silenced. Once control-setting operations are completed (or Escape is used), normal receiver operation will resume with its audio output restored.

While in the Edit mode, if no action is taken for approximately 30 seconds (no buttons pressed), the receiver will “back out” to the Menu mode. Similarly, after about 30 seconds of inaction in the Menu mode, the receiver will “back out” to normal receiver operation with audio output

estored.

High-pass Filter

Internal high-pass filter circuitry may be set to four positions: High-pass Off, or a 6 dB, 12 dB or 18 dB slope at 150 Hz. The default setting is Off high-pass filter further suppresses unwanted low frequencies, while maintaining the frequency response in the desired audio range.

Meter Hold Setting

When activated (“MH ON”), this function permits the bar-meters in the LCD window to capture and display the

highest-level “AF” audio modulation (a solid bar) and the lowest-level "RF" signal (a flashing bar) received from the

transmitter. This is particularly useful when setting up the system initially, during a sound-check, or when diagnosing operating problems. The default setting is Off

(“HP OFF”). Increasing the slope of the

(“MH OFF”).

When the Meter Hold is On, it is possible to reset it – to obtain a new set of RF and AF readings – without turning it off-and-on using the Menu/Edit functions. Simply press the transmitter’s Power/Mute button once (to mute the transmitter) and

until the Alert light has turned on, then turned off.)

Digital Tone Lock™Squelch

The 3000 Series employs a unique Digital Tone Lock squelch system that provides enhanced rejection of interference. In addition to providing highly effective control of unwanted noise, the Tone Lock signal from the transmitter also conveys data on the transmitter’s battery condition and mute status back to the receiver for display.

The squelch level is adjustable from 15 dB (the default value) to 42 dB in 3 dB steps. Increasing the squelch level – also called “tightening the squelch” – can cause a reduction in useable range of the wireless transmitter, so use the lowest value that reliably mutes the unwanted RF signals. (If interference is a problem, first consider trying a different frequency.)

ransmitter Controls And Functions

Refer to Figures E, F, G and H for an overview of transmitter features and controls.

LCD Window

The Liquid Crystal Display presents a great deal of setup and operating information clearly and conveniently (See examples in Fig. J). The LCD in the transmitters is designed for greatest contrast and best viewing with the window rotated somewhat away from the viewer (about 30 degrees), not straight-on, for a more convenient holding/viewing position.

Power/Mute Button

The transmitters have a combination Power and Mute switch. When used in combination with the programmed choices explained below, the various functions available to the transmitter user may be tailored to fit personal preferences or particular situations of use.

Power On/Off

To turn the transmitter on, press and hold the Power/Mute button until the red power indicator and the LCD window come on (about 1-2 seconds). The operating frequency will show in the window after the power-up sequence.

To turn the transmitter off, button again, until the red power indicator and the LCD window are extinguished (about 1-2 seconds). The LCD window will show

“PWR.OFF” before shutdown.

Mute Off/On

When the transmitter is muted, it produces RF with no audio signal modulation. When the transmitter is un-muted, it produces both RF and audio.

To mute the transmitter (cut off the audio, but continue the RF output), small frequency (Fig. J-2).

If an attempt is made to take an action that currently is locked out, the LCD will display

eviously-displayed contents.

Audio Input Selector

The UniPak™ body-pack transmitter provides input connections for both low-impedance (Lo-Z) microphones and highimpedance (Hi-Z) instruments. A wide range of Audio-Technica Wireless Essentials™ microphones and cables is available pre-terminated with the appropriate professional latching connector. (See page 11.)

Selection of the desired input – microphone or instrument – is made through the function menu. Depending upon the input selected, a small window, just below the frequency. (In the handheld transmitter, only

“MIC” will show in the LCD window.)

Setting Audio Input Level

A 4-position audio input gain setting, selected through the function menu, serves to match the audio input level to the transmitter for best modulation with minimum distortion.

Available choices are +12 dB, +6 dB, 0 dB and –6 dB. The default value is +6 dB. Select the highest setting that does not result in over-modulation with the highest audio/instrument input levels (an AF indication on the receiver no higher than “0”); watch the receiver’s “AF” meter “+3/+6” indications and the Alert light to make certain they are not triggered by the highest audio levels.
