The efficient class-D design keeps size and weight to a minimum while providing maximum power to your driver. SPA-D Amplifiers are perfect for subwoofer duty due to their high efficiency and low noise volume at lower frequencies making amplification selection easier than ever.

Connectivity

Front:

1. Power Input - This unit features an IEC Type power jack

2. Low-Level Inputs (Left/Right) - RCA Style jacks that will accept standard line level inputs from a pre-amp level source.

3. Output Lead for Subwoofer Driver - Solderless disconnect terminals for driver connection: Red = 0.205" / Black = 0.11"

4. Power/Clipping LED - This LED indicator will display the current status of the amplifier.

5. Volume (Gain) - This control will match the amplifier's input sensitivity to the output of the pre-amp source.

6. 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.

7. Phase - This two-position switch helps to compensate for differences between the acoustical and electrical characteristics between the subwoofer and main speakers.

8. Auto Turn On/Off - When the "auto" position is selected the amp is in standby mode until an input signal is detected.

9. Bass Boost - This allows the user to add a 6dB boost to the response centered at 35Hz.

    10. Main Power Switch - Main power disconnect.
