The Dayton Audio SPA300-D high-efficiency subwoofer plate amp packs big-amp features into a compact chassis that is ideal for installation into cabinets that can't accommodate bulky old-style amps. A Class-D topology makes it small, but with the same output capability as a traditional amplifier topology. We've included everything that you need to connect the amp to your system and get maximum performance! Key Specs: Channels: 1 Power Handling @ 4 ohms (RMS): 300 Watts Power Handling @ 4 ohms (MAX): 600 Watts Frequency Response: 40Hz - 200Hz Inputs: 2x RCA Inputs Outputs: 1x Powered Output USB Power Out Attach a Dayton Audio WLS System to the USB output and enjoy a wireless connection from your stereo system Variable Crossover Maintain a smooth transition from your full-range speakers with a variable low-pass filter.

Auto-On When no signal is present, the SPA300-D will shut itself off until you need it most! Class-D Excellence 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. USB Power Supply - 5V 500mA USB power supply. This output will supply power when the amplifier is on or in stand-by mode. 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 - This rear mounted output lead connects the amplifier to the subwoofer driver 4. Power Input - This unit features an IEC Type power jack. 5. Power/Clipping LED - This LED indicator will display the current status of the amplifier. 6. Volume (Gain) - This control will match the amplifier's input sensitivity to the output of the pre-amp source. 7. 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. 8. Phase - This two-position switch helps to compensate for differences between the acoustical and electrical characteristics between the subwoofer and main speakers. 9. Auto Turn On/Off - When the "auto" position is selected the amp is in standby mode until an input signal is detected. 10. Bass Boost - This allows the user to add a 6dB boost to the response centered at 30Hz. 11. Voltage Selector Switch - This switch allows the user to select 115/120VAC or 230/240VAC operation. 12. Main Power Switch - Main power disconnect.
