Product brief introduction

The A100 may be small in physical appearance but it will its got all the muscle you need to drive even the most demanding subwoofers to house thumping levels.
The A100 is a Class D 100 Watts subwoofer amplifier that when properly installed, runs cool under almost any load.
The A100 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 adjustable crossover allows fine-tuning the A100 low frequency input setting to properly complement any full-range speakers or room conditions.
In addition the A100 features a phase adjustment that provides sub performance optimization given the subs placement relative to the main speakers.
Finally, if you just need more thump, there is a Boost switch that will provide a 6dB boost at 40Hz...just in case you want some extra kick.
The A100 is auto-sensing so anytime an audio signal hits the A100 inputs, the amp will instantly turn ON. The amp will also turn itself OFF after 15 minutes when no audio signal ispresent.

There is also a 12VDC Trigger that will turn the A100 ON when 12-24VDC is applied and turn the amp OFF when the voltage is removed.

Operation guide for the A100 100W subwoofer audio power amplifier

Once installed and setup, the A100 doesn’t typically need a whole lot of attention. But just in case you need to tweak something, here’s what you’ll want to do...

ON/OFF
The A100 is auto-sensing, so typically once the system is installed and setup, the power will automatically turn ON with the presence of an audio signal on either of the L & R Line
Inputs. The amp will automatically turn OFF when no audio signal has been detected for 15 minutes.

TRIGGER - If you are using the Trigger IN, the amp will automatically turn ON when DC voltage is applied to the Trigger jack and turn OFF when DC voltage is removed..

POWER - If however you are a major control freak and just have to have the ability to turn the amp ON/OFF, toggle the Power ON/OFF button once to turn the amp ON/OFF.

VOLUME - Adjust the volume to the subwoofer until low frequency level has a smooth,natural sounding transition from the left and right speakers.

PHASE - The Phase setting allows compensation for subwoofer location relative to the main speakers. Adjust the Phase setting to the point of highest sub audio output.
RANGE: 0º to 180º of the subwoofer power amplifier.

CROSSOVER - The Crossover sets the frequency at which audio content will pass to the A100
Speaker Out. Adjust the crossover so there is a slight overlap with the low-midrange cutoff to produce a natural sounding transition to low frequencies.
RANGE: 40Hz to 160Hz.

BOOST- Set to 0dB for normal signal.

Set to 6dB for 6dB boost @ 40Hz.
