7.4 System controller variants
Three system controller variants offer a different maximum number of simultaneous audio
streams (for calls, tones, announcements, background music channels), to optimally match
system requirements and cost price. OMNEO channel routing is always dynamic and secure,
using audio encryption in the transmitting device and decryption in the receiving device.
Dante and AES67 channels are always static and not encrypted for easy compatibility between
systems of different brands. The PRAESENSA system controller can either encrypt up to eight
incoming streams to dynamic secure OMNEO streams, or decrypt up to eight dynamic secure
OMNEO streams to outgoing streams, or a mix of both with a maximum of eight. This is
sufficient for the PRA-SCM and PRA-SCS. But the PRA-SCL can receive up to 120 Dante or
AES67 channels, so 112 of these channels cannot be encrypted but are only converted to
open (unencrypted) dynamic OMNEO streams.
OMNEO streams are always dynamic multicast streams, routed from transmitter to one or
more receivers. The Dante and AES67 streams are static and received and/or transmitted by
the system controller, where they are encrypted, converted or decrypted.
