Dayton Audio SPA100-D 100 Watt Class-D Subwoofer Plate Amplifier

The plate amplifier that packs a punch!

The Dayton Audio SPA100-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): 100 Watts
  • Power Handling @ 4 ohms (MAX): 200 Watts
  • Frequency Response: 20Hz - 200Hz
  • Inputs: 2x RCA Inputs
  • Outputs: 1x Powered Output

Phase Switch

Correct misalignment between your speakers and your subwoofer with a phase inversion switch

Variable Crossover

Maintain a smooth transition from your full-range speakers with a variable low-pass filter.

Bass Boost

Get maximum performance from smaller drivers and enclosures with a switchable 6dB boost at 30Hz.

Auto-On

When no signal is present, the SPA100-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. 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 - This rear mounted output lead connects the amplifier to the subwoofer driver

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 30Hz.

    10. Main Power Switch - Main power disconnect.
