The VO-4 is a networked audio output expansion device allowing the user to add four line-level output channels to a Vocia® system. The VO-4 accepts four channels of digital audio input via CobraNet® and provides four line-level analog audio outputs. The VO-4 features embedded DSP and on-board memory to process and store all device-specific configuration information locally and includes comprehensive fixed-chain digital-signal processing. As part of the Vocia system, the VO-4 meets paging requirements for facilities of all sizes.
