## Overview

The OSD Audio SMP-100 is a compact, 100-Watt Class D mono subwoofer amplifier engineered for high efficiency and low heat output. It features an adjustable low-pass filter and front panel phase and volume controls, making it ideal for whole-house audio systems and dedicated home theaters seeking distortion-free, powerful bass.

## Description

OSD Audio's 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.

## Questions & Answers

**Q: how much power rms at 8 ohms?**
A: The manual mine came with "the 1000 Watt version" -- details it at providing 497 watts RMS at 8 ohms.

**Q: Anyone have an issue with the speaker out port not working?**
A: First off , do you have a audio signal out from the receiver/ amp to the input of subwoofer? Please check wiring diagram of the manual it should work.

**Q: Does the SMP100 require a 12v trigger cable to work properly?**
A: 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, but it also has the manual on/off switch.

**Q: Will this work with a polk s35 center channel speaker?**
A: Yes. But this amp would be overkill. Simply get an a/v receiver instead.
