Radio/Radio Amplifier Output

Audio signals are provided to the radio amplifier through three sets of inputs. The radio generates a chime signal and sends it via the chime data line whenever a chime is commanded via Class 2. Radio, tape player and in-dash CD player signals are sent from the radio via a pair of shielded audio lines. Output from the CD changer is sent via another pair of shielded audio lines. Accordingly, the radio amplifier has three separate input circuits. The radio amplifier processes these input signals, according to the equalization instructions sent from the radio via Class 2, amplifies them, and sends them out to the appropriate speakers.
