The PENTA 721s has 1 large user-configurable slot for one of the seven optional I/O cards including a 128 ch Dante interface. There is a slot for the optional Dual MADI Module labeled Optical I/O and includes as standard a Dante/AES67 Interface using the two Ethernet ports on the rear.
The large slot can be configured with any one of the seven available analog and digital cards, in addition to the digital interfaces provided on the base unit. Check out the features of each of the available Penta I/O cards here. Signal Routing
PENTA 721s include a 512×512 multiplexer, enabling all analog and digital inputs and outputs to be routed in any combination; this enables the unit to also split signals for advanced signal distribution. The multiplexer can be used to establish the static connections of the signal inputs and outputs, and furthermore, it incorporates soft switching with a fade down and fade up the functionality of the signal level. Soft switching ensures that setting or changing a signal path can be made without any audible click or artifact.
