Where does the ATT wire connect on a sony radio?

The ATT (attenuation) wire on a Sony car radio typically connects to the system's remote turn-on lead or can be connected to a compatible device that requires attenuation, such as an amplifier or a hands-free microphone. This wire helps reduce the volume when a call is received or when the audio signal needs to be lowered for clarity. Always refer to the specific wiring diagram for your model to ensure correct connections.
