OPERATION
OFF HI LO
Automatic Turn-On Selection: The DXA series offers two automatic turn-on modes; +12V and DC Offset.
•Remote Turn-On: Run 18 gauge wire from the Remote Turn-On Lead on your source unit to the terminal labeled REM between the amplifi er’s positive and negative power terminals.
•DC Offset Turn-On: The DC Offset mode detects a 6V DC offset from the HI-Level speaker outputs when the source unit has been turned on.
Input Level: The RCA inputs on KICKER DXA amplifi ers are capable of receiving either Hi or Low-level signals from your source unit. If the only output available from your source unit is a Hi-Level signal, simply press in the Input Level switch on the amplifi er. Refer to the wiring section of this manual for additional instructions.
Input Gain Control: The input gain control is not a volume control. It matches the output of the source unit to the input level of the amplifi er. Turn the source unit up to about 3/4 volume (if the source unit goes to 30, turn it to 25). Next, slowly turn (clockwise) the gain on the amplifi er up until you can hear audible distortion, then turn it down a little.
Crossover Control: The variable crossover on the side of the amplifi er allows you to set the crossover to OFF, HI-PASS, or LO-PASS at frequencies from 50Hz–200Hz. The setting for this control is subjective.
KICK EQ Bass Boost Control: The variable bass boost control on the side of the DXA125.2 amplifi er is designed to give you increased output, 0–12dB, at 40Hz. The setting for this control is subjective. If you turn it up, you must readjust the input gain control to avoid clipping the amplifi er.
