Thanks to the compact construction of the electronic components and the loudspeakers of the NOCH Sound Scenes, the noise is reproduced where it originally comes from. Thus, the ready-for-connection electronics can be installed in churches or the street musician module can be placed directly in a building next to the band. You will be surprised by the realistic sound reproduced in the centre of the action. The connection is made via a usual 16 V transformer, suitable for AC/DC. How to connect the sound module to a poser source: Connect the black cable directly to one oft he two light current outputs oft he transformer. Connect the red cable to the other light current output of the transformer. Now you can hear a permanent sound. If desired you can make the sound switchable. For this you can use a switch or a control panel (not included in the scope). Interrupt the electric circuit with this on/off switch at the red cable.
