OSD Audio’s SMP100 Class D Digital Subwoofer Amplifier is a compact 100W amp designed to power passive subwoofers used in a home theater or whole-house audio system. We call this our “tiny but mighty” powered sub because it measures less than six inches wide but supplies an in-wall or stand-alone subwoofer the power it needs so you can experience room-shaking low-frequency impact (bass) on movie and music soundtracks. The advanced crossover circuit can be set at different frequency ranges (35Hz to 160Hz) and is adjustable with a front-panel control knob. Other features include the front-panel adjustable phase and volume controls to dial in just the right amount of low-frequency effects (LFE). The SMP100 uses Class D amplifier technology that combines the best qualities of both Class A and B amp protocols into a highly efficient and compact digital design that is ideal for budget-minded users who want a feature-rich digital sub amp that does not run hot or take up a lot of space. With both RCA and speaker level connections, the SMP100 also acts as a distributed amplifier and will power a pair of in-ceiling speakers in addition to a sub. Auto On/Off Switch The SMP100 includes auto-sensing that turns on the amp when an audio signal is detected then turns off automatically after 15 minutes when a signal is not detected so no more worrying about whether you hit the off switch before bedtime. Master Volume Control When properly set up, the volume control on the SMP100 will control both the amp and the receiver volume to which it is connected for simple operation.
