Power/Mute Locks

Programmable Power/Mute Locks limit the functioning of the Power/Mute button as desired for particular users and/or applications. Power can be locked On; Mute can be locked Off. Selection of the desired locks, if any, is made through the function menu:

Setting	Description
NO.LOC	The normal Power and Mute functions are
	fully operational.
ALL.LOC	Power is locked On and Mute is locked Off
	when “ALL.LOC” is applied. When in the
	ALL.LOC mode, the transmitter may be
	turned off by (1) re-accessing the .LOC
	Menu and changing the setting, (2) pressing
	and holding the Up arrow button and the Set
	button at the same time, until the power
	goes off, or (3) removing and re-installing
	the batteries. When the transmitter is turned
	on again, it will power up in the NO.LOC
	mode.
MUT.LOC	In this mode, the audio cannot be muted
	(Mute function is locked Off). The Power
	functioning is unaffected.
	“Mute” Note: If ALL.LOC or MUT.LOC is
	applied while the transmitter is muted,
	pressing the Power/Mute button once will
	return the transmitter to un-muted operation;
	thereafter the Mute function is disabled
	(Mute Off) until the .LOC setting is changed
	again.
PWR.LOC	Power is locked On when “PWR.LOC” is
	applied. The Mute functioning is unaffected.
	When in the PWR.LOC mode, the transmitter
	may be turned off by: (1) Re-accessing the
	.LOC Menu and changing the setting,
	(2) Pressing and holding the Up arrow button
	and the Set button at the same time, until
	the power goes off, or (3) Removing and
	re-installing the batteries. When the
	transmitter is turned on again, it will power
	up in the NO.LOC mode.
	Note: Only the ALL.LOC or PWR.LOC Power
	function will change when batteries are
	removed; NO.LOC and MUT.LOC settings
	remain stored in memory.

If an action is attempted that currently is locked out, the transmitter LCD will briefly display “LOC.KED”, then return to its previously displayed contents.

Whenever any lock condition is applied to a transmitter, its associated receiver will display a small “TX LOCK” in the LCD window, just to the right of the frequency.

Audio Input Selector

The UniPak™ body-pack transmitter provides input connections for both low-impedance (Lo-Z) microphones and high- impedance (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 28.)

Selection of the desired input – microphone or instrument – is made through the function menu. Depending upon the input selected, a small “MIC” or “INST” will continue to show in the LCD window, just below the frequency. (In the handheld transmitters, “MIC” will always show in the LCD window.)

Setting Audio Input Level

AEW-T1000 UniPak: A 10-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 to –6 dB in 2 dB steps. The default value is +6 dB.

AEW-T4100 and AEW-T6100 Dynamic Handhelds:

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 to –6 dB in 6 dB steps. The default value is +6 dB.

AEW-T3300 and AEW-T5400 Condenser Handhelds:

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 attenua- tion is needed than the menu provides, then set the capsule’s pad switch to –6 dB.

For all transmitters: Select the highest audio level 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” meter “+6” indication and the Alert light to make certain they are not triggered often by the highest audio levels.

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