Rear Panel Operations and Connections

NOTE: Rear Panel color coding 

GREEN = Input 
RED = Output 

Input 1 

Input 1 is a priority input. This input functions the same as 

the other input channels but offers some added features suitable for 
paging microphones. Priority means “override”. Simply stated the 
microphone or line level signal will override all other inputs.  

RCA

 

UNBALANCED

- These jacks accept line level signals from CD's, 

DVD's, tuners etc. This is an unbalanced input that sums the signal to 

mono. The INPUT LEVEL knob does not affect the RCA input level. 

BALANCED - 

This is a balanced three-pin detachable terminal block 

connector that will accept microphone or line level sources. You can 
also connect an unbalanced source by connecting the HOT to + and 

connecting the COLD or (return) to G terminal. The INPUT LEVEL

 

control affects the input level for the terminal block input jack. 

INPUT LEVEL

 – This rotary control adjusts the input level for the 

terminal block connector only. Use this to match the correct input level 
based on the signal strength of the device connected. A good starting 
point is the 12:00 position. If you hear distortion turn the control 

counter clockwise. Turn this control clockwise to increase the input 
level.
