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 pages 21-22).
• 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.
Qt X 800/805 systems
• Each Qt X 800/805 controller has eight (8) outputs. Class 2 speaker
output runs are limited to single* 4Ω and 8Ω speakers (DS1357, DS1398)
or DS1320 active emitters.
• The Qt X 805/805D has an additional set of 8 line level outputs (mirroring
the Class 2 outputs) that can be connected to amplifiers to run DS1339 /
DS1390 70V sound masking loudspeakers.
• The Qt X 800/800D is designed for installation in the plenum space
and requires a PoE+ power supply (not included) for operation. The
Qt X 805/805D is a rack mounted unit and comes with a power supply.
• Since the controllers are networked, multiple outputs sharing the same
environmental, area and sound masking characteristics can be combined
in the same zone, which can then be configured in the software or via the
web interface.
*Note: Two DS1357 or DS1398 speakers may be daisy-chained on a single output for specic
coverage scenarios but are not able to be controlled/tuned individually in this instance.
