INTRODUCTION
Congratulations and thank you for purchasing the OSD AUDIO SMP100 Subwoofer Amplifier.
The SMP100 may be small in physical appearance but its got all the muscle you need to drive
even the most demanding subwoofers to house thumping levels.
The SMP100 is a Class D 100 Watt amplifier that when p roperly installed, runs cool under
almost any load.
The SMP100 features a stereo/mono line level audio input that can receive full band audio
from any audio amplifier, receiver or preamp or an LFE input from an appropriately featured
device.
The SMP100 also features a stereo speaker level input. Amplified stereo audio will pass through
the SMP100 full-band and unprocessed to a pair of connected stereo speakers. The speaker
level input will also be processed by the crossover, phase and volume controls to enhance and
optimize low frequency content. This feature is an easy way to add amplified in wall or in-ceiling
subwoofers to multi-room audio amplifiers that do not have zone-specific line level outputs.
The adjustable crossover allows fine-tuning the SMP100 Sub OUT setting to properly comple-
ment any full-range speakers or room conditions.
The SMP100 is audio-sensing so anytime an audio signal hits the SMP100 line or speaker level
inputs, the amp will instantly turn ON. The amp will also turn itself OFF after 15 minutes if no
audio signal has been detected. There is also a 12VDC Trigger that will turn the SMP100 on
when 12-24VDC is applied and turn the amp OFF when the voltage is removed.
Please read and follow the instructions in this User Guide to assure you are getting the most
from your new Subwoofer Amplifier.
