Cargo Area PA Pre-Amp Model CAPP-101

Cargo Area PA Pre-Amp Model CAPP-101

The CAPP replaces the integral Public Address System Amplifier (PAA) impedance and power matching function installed on the baseline C-130J Inter-Communication System which is lost with the LRS modification to an integrated ICS. The CAPP passes and amplifies unencrypted audio from the MICS to the Public Address system PAA on the baseline HC-130J LRS. The CAPP is a portion of the communications subsystem used aboard the HC-130J Mission System.
