    Digital Wireless W4
    Midi + Audio

    With the digital wireless system W4 you have chosen modernst technology. This system was specifically designed for Limex Midi System MPR4, but it should also work with other Midi products (please ask you local Limex dealer if it will work with your product).

    The digital wireless system W4 from Limex is using the license free 2.4 GHz ISM Band, therefore it can be used without registration. Best Quality, highest transmitting stability in real time and easiest usability were the main goals while developing this product.

    Our system is capable of transmitting 2-channel Audio (stereo signal) in very high quality (more than CD standard) and bidirectional Midi signals at the same time (Midi from Transmitter to receiver and vice versa). For all those who want to use the Limex foot pedal it is a must have add on for highest comfort.
