5. Choose one of the following options:
•SUB: Check to turn the sound from the SUB on; uncheck to turn it off.
•SUB Level: Use the slider to increase or decrease the volume of the SUB. (You can use this setting to
match the subwoofer level to the level of your main speakers.)
•Placement Adjustment (phase): Check or uncheck the box to adjust the phase.
•Speaker Size Adjustment (Crossover): This setting only appears when the SUB is associated with a
CONNECT:AMP or ZonePlayer 100. You may wish to choose a different setting from the drop-down list if:
• the main speakers sound distorted at high volumes—moving to a smaller speaker size setting can
help.
• your attention is drawn to the SUB's location while listening to music—moving to a larger speaker size
setting can help.
