How do I connect a subwoofer to the A1 or A1-MR ?

You can use either a single LFE RCA cable or stereo white/red RCA cable.

Connect FROM your powered speaker’s ‘Subwoofer’ output TO your subwoofer’s ‘Left’ RCA input or the subwoofer’s LFE input.

For stereo RCA cables, just use the left/white RCA cable, and leave the red RCA disconnected to prevent an accidental ground loop.

** Please note:  a 3.5mm/stereo mini cable will not work with the ‘Subwoofer’ output on the back of your A1/A1-MR speakers. **
