SERIAL NO.:
1. LINE IN: Stereo RCA input connectors for the audio source (mixer, karaoke player, home theater).
These inputs mix the left and right channel. If your audio source have mono output or subwoofer
output, you can connect using single RCA cable .
2. LINE OUT: Stereo RCA output for connecting another subwoofer or active speakers.
3. VOLUME: Adjust the volume of the subwoofer. Set to 0 when first time turning on and adjusting the
system.
4. L.P.F (Low Pass Filter): Adjust high frequency cutoff point. If rotated fully clockwise, it cuts high
frequencies above 150 Hz. Rotated fully counterclockwise, it cuts high frequencies above 50 Hz.
5. PHASE: Adjust the subwoofer’s output phase so it can be set to match the main speakers phase.If
the subwoofer were to play out of phase with the main speakers, the sound waves from the main
speakers could partially cancel out the sound waves from the subwoofer, reducing bass performance.
6. HIGH LEVEL INPUT: High level input for class AB amplifier. If your amplifier doesn’t have dedicated
subwoofer outputs or line outputs, you can connect the audio from amplifier’s high level speaker
outputs. Note! Class-D amplifier can not be connected using high level input because class D
amplifier needs floating load (speaker).
7. POWER LIGHT: Turns on when the power is turned on from the power switch.
8. POWER SWITCH: Turns the subwoofer on (I) or off (O).
9. POWER INPUT: Connect the power cable here.
