The USP4 Module offers the flexibility of being able to route the signal from the module and amplifier in two different ways; Analog Outputs and Foldback via CobraNet. This feature is not available in a Master Panel.
The Foldback control panel allows you to select what items should be transmitted via CobraNet. The selections available are the Analog Inputs or the Amplifier Outputs. The audio can only be routed out through one bundle.
Each of the processing channels can be routed to the analog output on the module independently. You set he location where the signal is taken from in the signal path using the radio buttons. It can be selected to be after the input source router, after the crossover before the output EQ, or after the LevelMAX™ processing. In addition there are level, mute, and polarity controls for each channel.
The Foldback control panel allows you to select what source should be used to transmit audio via CobraNet back onto the network.. The selections available are the Analog Inputs, AES Inputs, or the Amplifier Outputs. The audio can only be routed out through one bundle.
