HARMAN’s Crown Audio has announced its DCi Network Display Amplifiers are the first professional audio endpoints to receive AVnu certification for Audio Video Bridging (AVB) interoperability from the AVnu Alliance, the professional audio industry’s organization dedicated to driving open, standards-based AV networking through the certification of AVB products for interoperability.
Crown’s flagship DCi Network Series amplifiers potentially set a new standard for power and flexibility in large-scale installed sound applications. The eight-channel DCi 8|600ND delivers 600 watts into eight ohms (300, 600 and 300 watts into 16, four and two ohms) and the four-channel DCi 4|1250ND provides 1250 watts into eight, four or two ohms (625W into 16 ohms). Both amplifiers offer direct drive “constant voltage” capabilities for 70Vrms and 100Vrms amplification without the need for a step-up transformer, yielding higher audio quality in distributed audio applications with power outputs of 1250 watts and 600 watts respectively.
Crown DCi Network Display Amplifiers passed the testing procedures at an AVnu-appointed test house. AVnu Alliance funds the development of certification testing and its members are responsible for ensuring AVNu Alliance’s IEEE AVB compliance program meets demanding performance benchmarks. This is the first and only independent AV networking certification test program.
Certification, which is available to any member, is based on testing that takes place at the University of New Hampshire InterOperability Lab (UNH-IOL), which serves as AVnu’s independent testing facility. “AVnu Certification provides in-depth validation of member products against established standards enabling a healthy multi-source ecosystem,” said UNH-IOL’s Bob Noseworthy.
