Turning on the Transmitter, Setting Levels

System Operation (Continued)

Turning on the Transmitter

Turn on the transmitter by holding the Power/Mute button (see Figure J/K on page 18) for a second or two, until the red power indicator and the LCD window have come on. (When using a handheld transmitter, unscrew and slide down the lower body cover, as shown in Figures N/P on page 22.)

Setting Transmitter Frequency

Touch: A momentary press of the Mode/Set button. It is used to enter Menu mode, to enter Edit mode, or to Escape without making any changes to current settings.

Hold: A press and hold (about two seconds) of the Mode/Set button. It is used to accept a new setting when the receiver is in Edit mode or to save the current settings to one of the five user-defined name presets or the internal memory location (“NAME?”).

1.Touch the Set button once. The small word “MENU” appears above the frequency. Touch the Set button again and

the small flashing word “EDIT” appears to the right of

“MENU.” (The actual frequency flashes twice, then “EDIT” continues to flash.)

2.Use the Up/Down arrow buttons to change the transmitter frequency. Touch either arrow for single steps, or hold down either arrow for rapid cycling through the range. Frequencies “wrap around” when the top or bottom of the band is reached. Select the exact frequency displayed on the receiver.

3.To activate this frequency selection, hold the Set button until the word “STORED” appears in the transmitter’s window. (If you do not wish to complete this selection, just touch the Set button once: the word “ESCAPE” appears briefly in the window, and the transmitter returns to the Menu mode.)

4.When finished entering a frequency, touch the Up arrow button once to move to “QUIT.” Then touch the Set button once to exit the menu. The word “MENU” in the transmitter window disappears, indicating the return to normal operation.

5.If desired, assign a standard or custom Preset Name at this time as described on page 20 (To store Preset configurations), so this particular configuration can be recalled in the future.

If a new name is not assigned, the transmitter will continue to operate on this frequency (and with these settings) until some other change in settings is made.

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

Setting Levels

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

Setting Transmitter Audio Input Level

Multiple-position audio input gain settings, selected through the function menu, serve to match the audio input level to the transmitter for best modulation and highest signal-to-noise ratio with minimum distortion.

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 “+3”); watch the receiver’s “AF” bar-graph “+6” indication and the Alert light to make certain that they are not triggered by the highest audio levels.

Also, the transmitter’s red LED power indicator, which is on during normal operation, will blink off if the peak audio input reaches overload level.

Available Level Settings

AEW-T1000 UniPak™: Choices are +12 dB to –6 dB in 2 dB steps. The default setting is +6 dB.

AEW-T4100/6100 Dynamic Handhelds: Choices are +12 dB, +6 dB, 0 dB and –6 dB. The default setting is +6 dB.

AEW-T3300/5400 Condenser Handhelds: Choices are +12 dB, +6 dB and 0 dB. The default setting is +6 dB. A mechanical switch on the condenser capsule activates a 6 dB pad. For best performance, adjust the input level using the function menu choices first, keeping the capsule’s pad switch at 0 dB. If more audio attenuation is needed, set the capsule’s switch to –6 dB.

RF Power Adjustment

RF power may be set to “RF HI” (35 mW nominal) or “RF LOW” (10 mW nominal) through the function menu. The default setting is “RF LOW.” While the Hi setting normally provides maximum operating range, the Low setting will help extend battery life. The Low setting may also be preferred when using multi-channel systems, or when operating very close to the receiver, to reduce the possibility of interference or overload.

RF Interference

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....”
