FEATURES AND CONTROLS – STX MICRO-1

The STX MICRO-1 is a mono block amplifier that is designed to exclusively 
drive subwoofers. The fully variable crossover can be adjusted from 50Hz to 
250Hz to fine tune the amplifier for the subwoofer enclosure and speakers 
being used in the system. 

1. Low Pass Filter. This sets the lower limit of the frequency range for the 

amplifier. When the Low Pass Filter is set to 80Hz, the amplifier will pass 
all frequencies 80Hz and below.

2. Sensitivity. This control is used to match the input of the amplifier to 

the source unit. The higher the sensitivity the sooner the amp will reach 
maximum output.

3. Bass Boost. This is an equalization control that allows emphasis to be 

put on one frequency (45Hz) to increase the amplifier’s output at that one 
frequency. The farther to the right this control is set, the more output the 
amplifier will have at 45Hz. Care should be taken when using this control. 
Excessive bass boost can damage subwoofers!

4. Phase Control. This will reverse the phase of the subwoofer. The best way 

to set this is by ear. Whichever sounds best should be set and left alone.

5. Subsonic Filter. Asking the amplifier to amplify frequencies below the 

tuning or audible range of the subwoofer will cause the amplifier to work 
less efficiently. Adjusting this setting slightly below the tuning frequency 
of the enclosure will result in more efficient and reliable operation.

6. Power/Protect Indicator. This indicator will light up RED upon initial amp 

start up. If all connections are OK, within 3-5 seconds the light will turn to 
BLUE. If a condition of protect (short circuit, over/under voltage) occurs the 
light will turn to RED until the condition of protect is resolved.
