Connectivity Front:1. Power Input - This unit features an IEC Type power jack
Low-Level Inputs (Left/Right) - RCA Style jacks that will accept standard line level inputs from a pre-amp level source.
Output Lead for Subwoofer Driver - Solderless disconnect terminals for driver connection: Red = 0.205" / Black = 0.11"
Power/Clipping LED - This LED indicator will display the current status of the amplifier.
Volume (Gain) - This control will match the amplifier's input sensitivity to the output of the pre-amp source.
Frequency (Low-pass crossover) - This sets the highest frequency the subwoofer will reproduce and has a range between 40-200Hz with a slope of 18dB/Oct.
Phase - This two-position switch helps to compensate for differences between the acoustical and electrical characteristics between the subwoofer and main speakers.
Auto Turn On/Off - When the "auto" position is selected the amp is in standby mode until an input signal is detected.
Bass Boost - This allows the user to add a 6dB boost to the response centered at 35Hz.
