Jensen PA500 Скачать руководство пользователя страница 2

 
The JENSEN PA500 is a universal public address system 
that can be utilized as a stand alone PA (when connected 
to speakers) or operate in conjunction with any existing 
radio/speaker set up.

The PA500 system amplifier connects in line between the 
vehicle's radio and the installed speakers.   
The installed radio will operate normally.  When  
the microphone is activated by the "Push to Talk" (PTT) 
switch on the microphone, the speakers are electrically 
disconnected from the radio and engaged with the PA.  
The microphone triggers activation of the PA through 
the same speakers (muting/overriding the radio source).  
There is no need to adjust PA volume at the radio since 
the PA volume can be set using the volume/gain control 
on the PA500 itself.  If the PA500 is installed in an enclosure 
the volume level can be pre-set by the installer.
