Extension Speaker 

 
The Extension speaker jack is provided for connecting additional speakers to the amplifier.  This 
jack is wired in parallel with the main speaker jack (located on the underside of the chassis).  
When you attach a speaker using the external speaker jack, it will be connected in parallel with 
the internal speaker, and the internal speaker will remain operational.   
 
If you wish to drive only an external speaker, and to disconnect the internal speaker, then you 
must unplug the internal speaker from the main speaker jack location on the underside of the 
chassis and connect the external speaker to main speaker jack (not the extension speaker jack). 
 
 
 

Line Out 

 

The Line Out jack offers a level-matched version of the speaker signal with some basic EQ 
applied for use in driving a second amplifier or any line-level input such as a recording device.   
The Line-Out signal cannot be generated without signal begin sent to the speaker, so it is not 
possible to use it for silent recording.
