Connecting sub to sprout


hi there,

newbie question. Can I add a sub with only a LFE connection to my Sprout? I am looking at the Focal Dome sub. Thanks!


Hi hollis,

Thanks for reaching out to us about this. The LFE (low frequency effect) channel is the name of channel specifically intended for deep, low-pitched sounds ranging from 3-120 Hz. The Sprout does not have an LFE output per se but you can use the analog output to the LFE input to the SUB without serious issues to the audio performance.

Hope this is helpful.

Thanks! So just one rca to connect the sub to the analog output on the sub?


Hi hollis,

The Sprout has a 3.5mm Analog output jack in the back.

You’ll want to get an adapter to an RCA connector to hook it up.

One similar to this one:
