Z input This input feeds directly to the amplifier s mix bus through the front level control for the particular module bay and is not processed by the output module directly The input is included so that the input function of the module bay is not lost when an output module is installed Input Modules Functionality The Power Vector series of amplifiers accepts Bogen s new advanced input modules which provide a wide range of input types allowing the amplifier inputs to be custom configured in both type and number for a particular application Input modules can be installed into any of the 8 module bays and do not have to be installed in any particular bay order The front panel volume control for that number bay will control the mix level of that input module In addition to a host of module specific features each input module has a priority jumper section for creating a priority hierarchy between different inputs installed in the amplifier Priorities The Power Vector series of amplifiers allows inputs to be prioritized at four different levels The Bogen input modules contain circuitry that can cause their outputs to be muted in response to higher priority control signals from other input modules Each input module also contains circuitry that sends a mute control signal out to other modules when it becomes active all input modules become active when they receive an audio input Active modules may be prevented from sending their audio onto th
