Getting Started - BASIC - Step 3: Positioning the System Positioning the speakers For the best possible surround sound, all the speakers other than the subwoofer should be the same distance from the listening position (A). The front speakers can be placed from 0.0 to 7.0 meters (0 to 23 ft) (A) from the listening position. Install the IR transmitter and IR receiver of the surround speaker (L) in direct line with each other. For details, see "To adjust the IR transmitter and IR receiver of the surround speaker (L)" (page 23). Place speakers as illustrated below.

Tip • If transmission is poor, you can also connect the surround speakers to the system by the speaker cords (OPTION) (supplied). • When you change the positions of the speakers, it is recommended that you change the settings.
