Individualized audio equipment

Loudspeakers (here) not only serve the purpose of playing music, but also for issuing navigation messages, radio or telephony, be it cell phones or landlines via LTE. Monaural signals can be fed in via the right or left of the four stereo inputs and mixed if necessary.
If you reserve two stereo inputs for radio and TV, four mono channels remain for navigation, radio, telephone, as well as a reserve input.

In this respect, special attention must be paid to signal processing. It is important to mix monaural and stereo signals and output them to the amplifier at a suitable, balanced volume.

This is ideal for this MOUKEY 6-channel stereo mixer at. Each channel is adjustable, including the output level. Mono signals can be assigned to both channels using a switch.

A Bluetooth transceiver FT ABT 00102 takes over the BT transmission of, for example, navigation output from a tablet or cell phone audio, as well as feeding it into the Behringer interface.

A JBL STAGE A6002 acts as the final amplifier, and the audio output is also provided by a very inexpensive one Numan Ambience 2.0 Audio System.
