Description
The Q-SYS NL-C4 is a network PoE loudspeaker that delivers clear speech and music reproduction natively to Q -SYS. The ceiling-mount loudspeaker features a four-inch, full-range driver, and can be integrated into your space with a single Ethernet cable to reduce overall hardware footprint and lower system cost. As a native Q-SYS Product, you can take advantage of the drag-and-drop integration and simple control capabilities offered by Q-SYS.
As native Q-SYS products, the NL Series network loudspeakers offer easy drag-and-drop integration within Q-SYS Designer Software. To simplify the tuning process, Q-SYS automatically delivers custom loudspeaker voicings (Intrinsic Correction™) to NL Series loudspeakers. Additionally, NL Series network loudspeakers are the first loudspeakers that can be automatically monitored and managed by Q-SYS Reflect Enterprise Manager every step of the way, from the audio source all the way through the loudspeaker driver.
