Installation Considerations
Qt X 300/600 systems
• Output runs must have the same device type (Standard or Active Emitters)
and will share the same sound masking settings. The cabling runs must
be configured to prevent any signal interference among the 4 channels
along the layout. (Refer to illustrations
• Differences in ceiling height of more than 6" (152mm) need to be
connected as separate outputs because sound masking levels will be
different.
• Each output's sound masking levels can be individually controlled and
then assigned to networked zones with additional controls applied to the
whole zone.
