70/100V transformers have color coded
bare wire terminations to avoid the cost of
rotary selectors.
For enhanced performance and speedy
installs, implement model-specific
advanced voicing through QSC Intrinsic
Correction. QSC Intrinsic Correction™ is
available in the Q-SYS™ Platform and in
CXD Series amplifiers.
The high-quality weather treated paper
cone transducer features a whizzer cone
to improve high frequency dispersion
throughout the critical vocal range and
maintain speech intelligibility. The wide
dispersion angle lets you cover an area
evenly with fewer loudspeakers, even in
low-ceiling applications.
The easy-to-install blind mount assembly
