The PANARAY
®
system digital controller has the ability to run a single stereo preset, a single mono preset, or
to run in dual mono mode. In the following section, the controller's signal flow is broken down to provide a
better understanding of its full functionality.
Input CH1
Input CH2
Stereo Operation: When a preset is loaded from the stereo bank, the EQ/crossover blocks both process
each input the same way, meaning that the parameters are "linked". The signal then passes through the router
section where the CH1 and CH2 inputs are sent to independent output channels for stereo operation.
Mono Operation: When a preset is loaded from the mono bank, the EQ/crossover blocks both process each
input the same way, meaning that the parameters are "linked". The signal then passes through the router sec-
tion where the CH1 and CH2 inputs are summed to mono. The controller has the ability to sum a stereo signal
to mono, or, it can process a single input for mono operation. Audio information is routed to the same outputs
regardless of the number of inputs that are connected.
Dual Mono Operation: When the PANARAY
EQ/crossover blocks process each input independently – allowing the user to run two independent speaker
EQs. The router also processes each input independently, so each output is discrete.
