8 Connections and Control Settings AC Power Connection Replacing the Fuse The power cord should be firmly inserted into any conve- nient AC wall outlet. The CW10 also integrates a signal sensing power supply that automatically switches off after sensing no music signal for several minutes (this will cause the status LED to turn off). Your CW10 subw[...]

P laCement Placement 9 Generally, subwoofers have the most output when placed in the corner of a room. However, this can also exagger- ate the subwoofers output making blending difficult. We recommend starting by placing the CW10 in a corner. If, after the full range of tuning techniques have been employed, the su bw oo fe r s ou nd s l ik e i t ha[...]
