    The headphones interface (FKH-IF) from Limex is a small and versatile box which can be mounted directly onto your instrument or is detachable mounted on the base righten. As power supply a LiPo battery (8000 mAh) is used. This LiPo is connected to the headphones interface via a small USB cable which is plugged into the micro USB port from the headphones interface. At the top side the headphones interface has a 6,3 mm headphone jack and two indication LED. One lights up green after power is switched on. If Midi signals are receives the green LED is flashing. The second LED is used for the optional wireless functionality. This button will then switch on the wireless system which is indicated by a blue led.
