Dayton Audio SPA300-D 300 Watt Class-D Subwoofer Plate Amplifier

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!

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

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.

I bought this unit to replace a faulty amplifier in my Tannoy TS12. The sound is excellent and the performance of my system is excellent once again. It deals with high peaks from my demonstration discs with no signs of clipping - highly recommended!
