In lots of applications a local input control can be a useful and above all a timesaving product. No complex devices with multiple buttons to control just plug in and control the volume, nothing more, nothing less. Especially in rooms where very often a music source or microphone is used, the D-ALINP plays its role. Think of classrooms where each hour a different teacher uses the classroom and wants to plug in his laptop or meeting rooms where presentations are given on a regular basis. What about multi-function rooms, bars, restaurants or banquet rooms? With the D-ALINP you can connect your device in a blink of an eye.
