The CVA50-1 NET and NET+ are subcompact 50W mono 70V/100V networked power amplifiers built to meet the rigorous demands of high quality commercial, industrial and Pro Audio sound installations. The CVA50-1 NET version is designed with a Network only signal input, while the Net+ version has both Network and local inputs. A priority switch on the rear allows for selective ducking of either signal to allow one amplifier to do the work of two. These versatile dual input amplifiers allow for legacy audio devices to be used in a local setting while still having the flexibility of utilizing a networked signal. By setting the priority to local, the network could play background music until a signal is detected on the local inputs from a TV in a lobby. If the priority is set to network, a page could duck the TV output in a training room. These lightweight Class D amplifiers straddle the digital divide using all the benefits of the networked audio and while allowing for legacy device use.
