CAS computer unit. The output at RMP-2F and -2G supply high-level (up to 8 W)
audio signals to an 8-ohm speaker. The second output at RMP-3F and -3G supply
low-level (up to 80 mW) audio signals to a 600-ohm audio distribution system. All
aural traffic and resolution advisories can be annunciated over these outputs unless
cancelled by a Cancel Discrete (RMP-3D).
