Certain Loudmouth

™

 options affect operation as follows: 

With this feature enabled the Loudmouth

™

 will sound a short tone prior to each broadcast to notify listeners that 

a page is forthcoming.   

 

Set the Loudmouth

™

 for one or two speaker operation to set the correct audio output level from the audio 

amplifier. 

 

 

Feedback is the result of the Loudmouth

™

 speaker audio getting back into the microphone of the radio being used 

to access the Loudmouth

™

.  This is a problem with the calling radio, not the Loudmouth

™

 receiver.  Although the 

Loudmouth

™

 is not intended to be used in the same area as the calling radio, steps can be taken to minimize the 

feedback effect. 

 
Reduce Loudmouth

Do not set the Loudmouth

™

 volume any high than is necessary to cover the intended area. 

 

The use of multiple speakers means you don’t have to cover as large an area with each speaker, consequently, 
speaker volume can be reduced. 

 

In general, the calling radio should be at least 50 feet away from the speaker when the Loudmouth

™

 is set for 

50% volume.  The necessary distance increases if the volume is turned up and decreases if the volume is 
turned down. 

 

You do not want the speaker pointing directly into the microphone.  Using your hand to shield the microphone 
can also reduce feedback. 

 

Equip your calling radio with an optional noise-canceling microphone. 

 

The Record and Play feature completely eliminates feedback by recording your 
message and playing it back immediately after you have finished sending it to the 
Loudmouth

™

 receiver.   See page 18 to enable the Record and Play operation. 

The calling radio is not transmitting while the message is broadcast, so speaker 
audio cannot get into the calling radio microphone.
