AMPLIFIER FEATURE  DESCRIPTIONS

AT-SERIES AMPLIFIERS:

 Each model is capable of 4 & 2-Ohms stereo  per channel, or 4-Ohms mono bridged 

 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 

 Tri-Mode operation with any stereo pair of amplifier channels  is possible, as with  all

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.
