device. This jack is always active and is a pre-gain  
output.  
u Power Cord:  
This supplies AC power to the amplifier. If the  
cord becomes damaged, take the amplifier to an  
authorized service center for repair.  
{ Effects Send Jack:  
Use this jack to connect to the input of an external  
effects processor. This jack can also be used as a  
preamp out.  
v Speaker Output:  
This jack is used to connect the amplifier to
