    Turn down the volume control on the SubOne i Controller to its lowest position (counter-clockwise). Turn on your audio system, including the SubOne i. Play some music you are familiar with and set your receiver/pre- amplifier volume to a comfortable listening level. Slowly increase the volume on the SubOne i Controller, lis- tening for proper frequency balance.

In the “Video Contour” mode, the SubOne i has boosted output between 40Hz and the low pass frequency, and rolls off response below 35Hz to provide greater power han- dling at elevated listening levels.

With an RCA intercon- nect cable, connect the receiver’s “Pre-Out” to the SubOne i Controller’s LINE IN. Connect a second RCA interconnect cable from the SubOne i Controller’s SATELLITE LINE OUT back to the receiver’s “Main-In.”...
