Audio Level Program Pin No.1 (NO)
Two synthesized voice outputs with programmable output levels are provided by
the T

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).
Listed below are the audio level program pin configurations and the resulting output
levels:
