3000 Series Installation and Operation

4.Use the Up/Down arrow buttons to change the second three digits to the desired frequency.

5.To activate this frequency selection, press and hold the Set button until the word “STORED” appears in the transmitter’s window. (If you do not wish to complete this selection, just press the Set button

once: the word “ESCAPE” will appear briefly in the window and the transmitter will return to the Menu mode.)

6.When finished entering a frequency, press the Up arrow button once to move to “QUIT”. Then press the Set button once to exit the menu. The word “MENU” in the transmitter window will go off, indicating the return to normal operation.

When the transmitter is switched on and in normal operation, the receiver’s “RF” signal-level bars will display from bottom to top, with more bars indicating increased signal reception. For optimum performance at least four, and preferably five or more, of the RF indicators should be displayed.

Setting Transmitter Audio Input Levels

Correct adjustment of transmitter audio input, receiver audio output, and mixer/amplifier input and output levels is important for optimum system performance.

ATW-T310b and ATW-T341b Transmitters

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”).

ATW-T371b Transmitter

A 3-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, and 0 dB. The default value is +6 dB. In addition, a mechanical pad switch on the condenser capsule (inside the screw-on wire mesh grille) can provide another 6 dB of attenuation. For best performance, adjust the input level using the function menu choices, keeping the capsule’s mechanical switch at 0 dB. If more audio attenuation is needed than the menu provides, then set the capsule’s pad switch to - 6 dB.

RF Power Adjustment

RF power may be set to “RF HI” (30 mW nominal) or “RF LOW”

(10 mW nominal) through the function menu. The default setting is “RF LOW”. While the High setting normally provides maximum operating range, the Low setting will help extend battery life. The Low setting may also be preferred in multichannel systems, or when operating very close to the receiver, to reduce the possibility of interference

or overload.

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.

Ten Tips to Obtain the Best Results

1.Use only fresh alkaline batteries. Do not use “general purpose” (carbon-zinc) batteries.

2.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.

3.The transmitter and the receiver should be as close together as conveniently possible, but no closer than three feet (1 m).

4.Avoid placing the receiver in a low or shielded location where the transmitter and receiver antennas are not within line-of-sight. If necessary, use remotely-located receiver antennas.

5.Avoid placing the receiver near computers or other RF generating equipment.

6.The receiver and transmitter must be set to the same frequency.

7.A receiver cannot receive signals from two transmitters at the same time.

8.Do not obstruct the handheld transmitter’s antenna (located at the base) or attached body-pack transmitter’s antenna with your hands.

9.You need to change frequencies 1) when a strong interference signal is received, 2) when audio quality is poor due to weak RF, or 3) during multiple-system operation in order to select an interference-free frequency.

10.Turn the transmitter off when not in use. Remove the batteries if the transmitter is not to be used for a period of time.
