SUPER SPORT AMPLIFIERS:
!Each model is capable of 4 & 
!
!The input sensitivities for rated output powers are variable from 0.2 volt to 5 volt.
!All crossovers are fully variable in their respective ranges.
!Crossover filters are 12dB/Octave.
!A POWER LED indicates the powered up and turned on condition.
!All Autotek amplifiers feature a comprehensive diagnostic system, with speaker lead short circuit, and amplifier DC faults indicated by the red “PROTECT” LED.
!CAUTION: DO NOT OPERATE ANY AMPLIFIER BELOW THE INTENDED IMPEDANCE.. YOU WILL CAUSE DAMAGE TO THE AMPLIFIER THAT WILL NOT BE COVERED UNDER THE WARRANTY PRINTED IN THE BACK OF THE MANUAL. 2 & 4 Channel amps are capable of 4 and 
The 
MODE: The mode switch allows you to choose Stereo for full range 2 channel operation or MONO for bridging operation
HIGH INPUT: If your radio/CD player does not have unbalanced (RCA) outputs, you can use the HIGH level (wire) inputs.
LINE INPUT: The line input accepts unbalanced (RCA) inputs from 0.2V to 5V.
LINE OUTPUT: The line output passes through signal from the line inputs which allows you to daisy chain multiple amplifiers from one signal.
The 4 channel amps have the same features as the 2 channel models accept that there are 2 sets of controls.
1 set for channels 1 & 2 and 1 set for channels 3 & 4.
In addition, the 4 channel models have a Mode switch which allows you to select 2, 3 or 4 channel operation.
The 
MODE: The mode switch allows you to choose Stereo for full range 2 channel operation or MONO for bridging operation

LINE INPUT: The line input accepts unbalanced (RCA) inputs from 0.2V to 5V.
LINE OUTPUT: The line output passes through signal from the line inputs which allows you to daisy chain multiple amplifiers from one signal.
