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!
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
- 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 - This rear mounted output lead connects the amplifier to the subwoofer driver
- 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 30Hz.
- Main Power Switch - Main power disconnect.
Note: Speakers with a burned voice coil are not returnable for exchange, repair, or refund credit, as this is not covered by its warranty.
