(1) Power Switch — Use this switch to power the unit 
ON or OFF.
(2) AC Power Cord IEC Connector — This standard 
IEC power cord receptacle features a built-in fuse 
holder.
(3) Power ON LED
(4) Clipping LED — This LED indicator turns red when 
the output signal is 3dB below clipping. It is acceptable 
if the red LED lights very occasionally. If the red LED 
lights more than occasionally, you should turn down 
the volume to avoid audible distortion and damage to 
the speaker.
Note: Speakers damaged due to hard clipping are 
not covered under warranty.
(5) AC Voltage Selector Switch — Before plugging in 
the power cord, check to see that the unit is set for the 
proper voltage for your area: ~115V (60Hz) or ~230V 
(50Hz).
(6) Line Inputs — These Balanced XLR and 1/4’ 
TRS jacks accept Line Level balanced or unbalanced 
signals.  These inputs can be used as outputs also for 
easy thru-put when daisy-chaining powered speakers.
(7) RCA Inputs — These dual RCA low line level 
inputs can be used singly or together, as they are 
mono’d together to ensure subwoofer frequencies from 
both Left and Right signals are accounted for. 
(8) Low Pass Control — This sets the upper band-
width frequency of the low pass filter from 60Hz to 
260Hz.  Adjust this control for the desired punch of the 
subwoofer depending on the audio desired to fit the 
music and environment.
(9) Volume Control — This adjusts the subwoofer 
volume level. This can be set to maximum if the user 
prefers to control the volume at the preceding unit.  
Make sure not to overpower your speaker by noting 
the appropriate level at the mixing board fader con-
trol and LED bargraph to avoid clipping.  Over-driven 
speakers due to improper use are not covered under 
warranty.
