It's equipped with stereo RCA inputs, providing the option of a stereo connection or using only the left as an LFE input. One LINK can control two Totem wireless subwoofers. Set up is simple, just connect the LINK to the amp or powered speaker, push the pairing button, and push the pairing button on the sub. That's all you need to do to enjoy powerful bas delivered wirelessly, by the NEW TOTEM LINK.
