Well...since the Final Countdown was a time travel movie, my guess is this:

The RR2150 will be an update of the IBCM, only the RR2150 will be 5 channel audio switcher which will include TIME management as well as bass management. It will have inputs for two (or more) 5 channel analog devices.

How it will manage the time equilization? I don't know...that's why the outlaws are the outlaws and I'm just a guy who buys their brilliant stuff.

And since, ultimatly, in The Final Countdown the crew opted to do nothing and not interfere with the attack on Pearl Harbor, that's what the RR2150 will do...absolutly nothing to your audio signal. It will be a completly clean sound which simply enables you to balance your 5ch analog imputs to your listening room.
