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 dual-color LED Power/Mute indicator, which is on during normal operation, will
blink off if the peak audio input reaches overload level.
Available Level Settings
AEW-T1000a UniPak™: Choices are +12 dB to –6 dB in 2 dB steps. The default setting is +6 dB.
AEW-T4100a/6100a Dynamic Handhelds: Choices are +12 dB, +6 dB, 0 dB and –6 dB. The default setting
is +6 dB.
AEW-T3300a/5400a 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....” If you need assistance with operation or
frequency selection, please contact your dealer or the Audio-Technica professional division. Extensive
information on using wireless microphones is also available on the Audio-Technica Web site at
www.audio-technica.com.
